5 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMedingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · Q2 2026 $835.20 $3,340.79 / 4 syringes
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through Aug 2039. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

LOE
Substance patent Formulation patent Method-of-use patent Exclusivity Pediatric +6mo
🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of BREKIYA 1 MG/ML AUTOINJECTOR?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for BREKIYA 1 MG/ML AUTOINJECTOR. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Aug 2039 — an estimate, not a guaranteed launch date.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Brekiya — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Brekiya. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 64896-509-02, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 64896-0509-02, written without dashes as 64896050902. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 64896-0509-02, the first segment (64896) is the labeler code FDA assigned to Amneal Pharmaceuticals LLC; the middle segment (0509) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (02) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Amneal Pharmaceuticals LLC. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Amneal Pharmaceuticals LLC is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.

🚨 Boxed Warning 159 words

WARNING: PERIPHERAL ISCHEMIA FOLLOWING COADMINISTRATION WITH STRONG CYP3A4 INHIBITORS Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of dihydroergotamine with strong CYP3A4 inhibitors. Because CYP3A4 inhibition elevates the serum levels of dihydroergotamine, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased. Hence, concomitant use of BREKIYA with strong CYP3A4 inhibitors is contraindicated [see Contraindications (4) , Warnings and Precautions (5.1) , and Drug Interactions (7.1) ].

WARNING: PERIPHERAL ISCHEMIA FOLLOWING COADMINISTRATION WITH STRONG CYP3A4 INHIBITORS See full prescribing information for complete boxed warning. Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of dihydroergotamine with strong CYP3A4 inhibitors including protease inhibitors and macrolide antibiotics. Because CYP3A4 inhibition elevates the serum levels of dihydroergotamine, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased.

Hence, concomitant use of BREKIYA with strong CYP3A4 inhibitors is contraindicated [see Contraindications (4) and Warnings and Precautions (5.1) ].

⏱️ Dosage and Administration ~2 min read

2 DOSAGE AND ADMINISTRATION For subcutaneous injection only. ( 2.1 ) Recommended dosage is 1 mg administered subcutaneously as a single 1 mL autoinjector. ( 2.1 ) Do not exceed 3 mg (3 doses) in a 24-hour period. ( 2.1 ) Do not exceed 6 mg (6 doses) in a week. ( 2.1 ) Prior to initiation, a cardiovascular evaluation is recommended. ( 2.2 )

2.1Recommended Dosage BREKIYA autoinjector is for subcutaneous injection only. The recommended dose of BREKIYA is 1 mg administered subcutaneously via a single 1 mL autoinjector. The dose may be repeated, as needed, at 1-hour intervals to a total maximum of 3 mg (3 doses) in a 24-hour period. Do not exceed 6 mg (6 doses) total in a week.

2.2Assessment Prior to First Dose Prior to initiation of BREKIYA, a cardiovascular evaluation is recommended [see Warnings and Precautions (5.3) ] . For patients with risk factors predictive of coronary artery disease who are determined to have a satisfactory cardiovascular evaluation, it is strongly recommended that administration of the first dose of BREKIYA take place in the setting of an equipped healthcare facility.

2.3Important Administration Instructions See the “Instructions for Use” for detailed steps for administering the subcutaneous injection using the autoinjector. Preparation BREKIYA is a prefilled, single-dose disposable autoinjector intended to be given subcutaneously into the skin of the middle thigh. Rotate injection sites.

Choose an injection site at least 2 inches away from the last injection site. Do not inject into moles, scars, birthmarks, or areas where the skin is tender, bruised, red, or hard. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

Carefully examine the liquid medication for discoloration, cloudiness, floating flakes or particles. Administer only if clear and colorless. Administration Remove the red needle cap by pulling it straight off.

Position the autoinjector straight onto the cleaned injection site with the white safety guard resting on the skin. Push the autoinjector down and press and release the gray activation button to start the injection. A “click” will sound when the injection starts.

The autoinjector takes approximately 10 seconds to deliver the dose; when the viewing window is fully blocked (completely blue), the full dose has been administered.

( 5.7 , 8.1 ) Fibrotic Complications: Pleural and retroperitoneal fibrosis have been reported following prolonged daily use of dihydroergotamine mesylate. Do not exceed the BREKIYA dosing guidelines or use for chronic daily administration. ( 5.8 )

5.1Peripheral Ischemia Following Coadministration with Strong CYP3A4 Inhibitors Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of dihydroergotamine and strong CYP3A4 inhibitors. Because CYP3A4 inhibition elevates the serum levels of dihydroergotamine, the risk for vasospasm leading to cerebral ischemia and/or and ischemia of the extremities is increased. Hence, concomitant use of BREKIYA with strong CYP3A4 inhibitors is contraindicated [see Contraindications (4) and Drug Interactions (7.1) ].

5.2Myocardial Ischemia and/or Infarction, Other Cardiac Adverse Reactions, and Fatalities The potential for cardiac adverse reactions exists with BREKIYA treatment. Serious adverse cardiac events, including some that have been fatal, have occurred following use of dihydroergotamine mesylate. These events have included acute myocardial infarction, life-threatening disturbances of cardiac rhythm (e.g., ventricular tachycardia and ventricular fibrillation), coronary artery vasospasm, and transient myocardial ischemia.

Prior to initiation of BREKIYA, a cardiovascular evaluation is recommended to determine if the patient is free of coronary artery and ischemic myocardial disease or other significant underlying cardiovascular disease. If, during the cardiovascular evaluation, the patient’s medical history (including risk factors), or electrocardiographic investigation findings are consistent with coronary artery vasospasm or myocardial ischemia, BREKIYA should not be administered [see Contraindications (4) ]. For patients with risk factors predictive of coronary artery disease (e.g., hypertension, hypercholesterolemia, smoker, obesity, diabetes, strong family history of coronary artery disease, females who are surgically or physiologically postmenopausal, or males who are over 40 years of age) who are determined to have a satisfactory cardiovascular evaluation, it is strongly recommended that administration of the first dose of BREKIYA take place in the setting of an equipped healthcare facility, unless the patient has previously received dihydroergotamine.

During the interval immediately following the first use of BREKIYA, an electrocardiogram is recommended in those patients with risk factors because ischemia can occur in the absence of clinical symptoms.

5.3Cerebrovascular Adverse Reactions and Fatalities The potential for adverse cerebrovascular events exists with BREKIYA treatment. Cerebral hemorrhage, subarachnoid hemorrhage, stroke, and other cerebrovascular events have been reported in patients treated with dihydroergotamine mesylate; and some have resulted in fatalities. In a number of cases, it appears possible that the cerebrovascular events were primary, the dihydroergotamine mesylate having been administered in the incorrect belief that the symptoms experienced were a consequence of migraine, when they were not.

It should be noted that patients with migraine may be at increased risk of certain c…

6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Peripheral Ischemia Following Coadministration with Strong CYP3A4 Inhibitors [see Boxed Warning and Warnings and Precautions (5.1) ] Myocardial Ischemia and/or Infarction, Other Cardiac Adverse Reactions, and Fatalities [see Warnings and Precautions (5.2) ] Cerebrovascular Adverse Reactions and Fatalities [see Warnings and Precautions (5.3) ] Other Vasospasm Related Adverse Reactions [see Warnings and Precautions (5.4) ] Increase in Blood Pressure [see Warnings and Precautions (5.5) ] Medication Overuse Headache [see Warnings and Precautions (5.6) ] Preterm Labor [see Warnings and Precautions (5.7) ] Fibrotic Complications [see Warnings and Precautions (5.8) ] Hypersensitivity [see Warnings and Precautions (5.9) ] The following adverse reactions associated with the use of dihydroergotamine were identified in clinical studies or postmarketing reports.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to the drug exposure. Serious cardiac events, including some that have been fatal, have occurred following use of dihydroergotamine. Events reported have included coronary artery vasospasm, transient myocardial ischemia, myocardial infarction, ventricular tachycardia, and ventricular fibrillation [see Contraindications (4) and Warnings and Precautions (5.2) ].

Fibrotic complications have been reported in association with long term use of injectable dihydroergotamine mesylate [see Warnings and Precautions (5.8) ]. Vasospasm, paresthesia, hypertension, dizziness, anxiety, dyspnea, headache, flushing, diarrhea, rash, increased sweating, and pleural and retroperitoneal fibrosis occurred after long-term use of dihydroergotamine. Cases of myocardial infarction and stroke have been reported following the use of dihydroergotamine [see Warnings and Precautions (5.2 , 5.3 )].

Serious cardiac events (including fatal) that have been reported with dihydroergotamine mesylate injection use include coronary artery vasospasm, transient myocardial ischemia, myocardial infarction, ventricular tachycardia, ventricular fibrillation.

7 DRUG INTERACTIONS Beta Blockers/Nicotine: May potentiate/provoke vasoconstriction. ( 7.3 , 7.5 ) Selective Serotonin Reuptake Inhibitors: Weakness, hyperreflexia, and incoordination may occur with coadministration. ( 7.6 )

7.1CYP3A4 Inhibitors There have been rare reports of serious adverse events in connection with the coadministration of intravenous administration of dihydroergotamine and strong CYP3A4 inhibitors resulting in vasospasm that led to cerebral ischemia and/or ischemia of the extremities [see Warnings and Precautions (5.1) ]. The use of strong CYP3A4 inhibitors with BREKIYA is contraindicated [see Contraindications (4) ]. Administer moderate CYP3A4 inhibitors with caution.

7.2Triptans Triptans (serotonin [5-HT 1B/1D receptor agonists) have been reported to cause coronary artery vasospasm, and its effect could be additive with BREKIYA. Therefore, triptans and BREKIYA should not be taken within 24 hours of each other [see Contraindications (4) ].

7.3Beta Blockers There have been reports that propranolol may potentiate the vasoconstrictive action of ergotamine by blocking the vasodilating property of epinephrine.

7.4Vasoconstrictors BREKIYA is contraindicated for use with peripheral and central vasoconstrictors because the combination may cause synergistic elevation of blood pressure [see Warnings and Precautions (5.5) ].

7.5Nicotine Nicotine may provoke vasoconstriction in some patients, predisposing to a greater ischemic response to ergot therapy [see Warnings and Precautions (5.4) ] .

7.6Selective Serotonin Reuptake Inhibitors Weakness, hyperreflexia, and incoordination have been reported rarely when 5-HT 1 agonists have been co-administered with selective serotonin reuptake inhibitors (SSRI’s) (e.g., fluoxetine, fluvoxamine, paroxetine, sertraline).

👥 Use in Specific Populations ~3 min read

8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm. ( 8.1 ) Lactation: Advise not to use during breastfeeding. ( 8.2 )

8.1Pregnancy Risk Summary Available data from published literature indicate an increased risk of preterm delivery with dihydroergotamine, the active moiety in BREKIYA, use during pregnancy. Avoid use of BREKIYA during pregnancy [see Warnings and Precautions (5.7) ] . Data collected over decades have shown no increased risk of major birth defects or miscarriage with the use of dihydroergotamine mesylate during pregnancy .

In animal reproduction studies, adverse effects on development were observed following administration of dihydroergotamine mesylate during pregnancy (decreased fetal body weight and/or skeletal ossification) in rats and rabbits or during pregnancy and lactation in rats (decreased body weight and impaired reproductive function in the offspring) at doses that were not associated with maternal toxicity (see Data). The estimated rate of major birth defects (2.2% to 2.9%) and miscarriage (17%) among deliveries to women with migraine are similar to rates reported in women without migraine.

All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriages in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Published data have suggested that women with migraine may be at increased risk of preeclampsia and gestational hypertension during pregnancy.

Data Animal Data Intranasal administration of dihydroergotamine mesylate to pregnant rats throughout the period of organogenesis resulted in decreased fetal body weight and/or skeletal ossification at doses of 0.16 mg/day or greater. A no-effect level for adverse effects on embryofetal toxicity was not identified in rats. Intranasal administration of dihydroergotamine mesylate to pregnant rabbits throughout organogenesis resulted in decreased skeletal ossification at 3.6 mg/day.

The no-effect dose for adverse effects on embryofetal toxicity in rabbits was 1.2 mg/day. Intranasal administration of dihydroergotamine mesylate to female rats throughout pregnancy and lactation resulted in decreased body weight and impaired reproductive function (decreased mating indices) in the offspring at doses of 0.16 mg/day or greater. A no-effect dose for adverse developmental effects in rats was not established.

Effects on offspring development occurred at doses below those that produced evidence of maternal toxicity in these studies. Dihydroergotamine-induced intrauterine growth retardation has been attributed to reduced uteroplacental blood flow resulting from prolonged vasoconstriction of the uterine vessels and/or increased myometrial tone.

8.2Lactation Risk Summary There are no data on the presence of dihydroergotamine in human milk; however, ergotamine, a related drug, is excreted in human milk. There are reports of vomiting, diarrhea, weak pulse, and unstable blood pressure in breastfed infants exposed to ergotamine. BREKIYA may reduce milk supply because it may decrease prolactin levels.

Because of the potential for reduced milk supply and serious adverse events in the breastfed infant, including diarrhea, vomiting, weak pulse, and unstable blood pressure; advise patients not to breastfeed during treatment with BREKIYA and for 3 days after the last dose. Breast milk supply during this time should be pumped and discarded.

8.4Pediatric Use Safety and effectiveness in pediatric patients have not been established.

8.5Geriatric Use Clinical studies of dihydroergotamine products did not include sufficient numbers of subjects aged 65 and older to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end o…

🆘 Overdosage 163 words

10 OVERDOSAGE Symptoms Excessive doses of dihydroergotamine may result in peripheral signs and symptoms of ergotism. In general, the symptoms of an acute BREKIYA overdose may be similar to those of an ergotamine overdose, although there may be less pronounced nausea and vomiting with BREKIYA. The symptoms of an ergotamine overdose include the following: numbness, tingling, pain, and cyanosis of the extremities associated with diminished or absent peripheral pulses; respiratory depression; an increase and/or decrease in blood pressure, usually in that order; confusion, delirium, convulsions, and coma; and/or some degree of nausea, vomiting, and abdominal pain.

In laboratory animals, dihydroergotamine was lethal when given at intravenous doses of 44 mg/kg in mice, 130 mg/kg in rats, and 37 mg/kg in rabbits. Treatment Treatment includes discontinuance of the drug, local application of warmth to the affected area, the administration of vasodilators, and nursing care to prevent tissue damage. Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.

🧬 Clinical Pharmacology ~2 min read

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Dihydroergotamine binds with high affinity to 5-HT 1Dα and 5-HT 1Dβ receptors. The therapeutic activity of dihydroergotamine in migraine is generally attributed to the agonist effects at 5-HT 1D receptors.

12.2Pharmacodynamics Significant elevation in blood pressure has been reported in patients treated with dihydroergotamine with and without a history of hypertension [see Warnings and Precautions (5.5) ]. Dihydroergotamine possesses oxytocic properties .

12.3Pharmacokinetics Absorption Following BREKIYA administration, the mean maximum plasma concentration was 3.8 ng/mL, and the median time from dosing to maximum plasma concentration was approximately 0.4 hours. Distribution Dihydroergotamine mesylate is 93% plasma protein bound. The apparent steady-state volume of distribution is approximately 800 liters.

Elimination Metabolism Four dihydroergotamine mesylate metabolites have been identified in human plasma following oral administration. The major metabolite, 8´-β-hydroxydihydroergotamine, exhibits affinity equivalent to its parent for adrenergic and 5-HT receptors and demonstrates equivalent potency in several venoconstrictor activity models, in vivo and in vitro . The other metabolites (i.e., dihydrolysergic acid, dihydrolysergic amide, and a metabolite formed by oxidative opening of the proline ring) are of minor importance.

Following nasal administration, total metabolites represent only 20% to 30% of plasma AUC. Quantitative pharmacokinetic characterization of the four metabolites has not been performed. Excretion The major excretory route of dihydroergotamine is via the bile in the feces.

The total body clearance is

1.5L/min which reflects mainly hepatic clearance. Only 6% to 7% of unchanged dihydroergotamine is excreted in the urine after intramuscular injection. The renal clearance (0.1 L/min) is unaffected by the route of dihydroergotamine administration.

The decline of plasma dihydroergotamine after intramuscular or intravenous administration is multi-exponential with a terminal half-life of about 9 hours. Specific Populations No studies have been conducted on the effect of renal or hepatic impairment, gender, race, or ethnicity on dihydroergotamine pharmacokinetics [see Contraindications (4) ]. Drug Interaction Studies Pharmacokinetic interactions have been reported in patients treated orally with other ergot alkaloids (e.g., increased levels of ergotamine) and macrolide antibiotics, presumably due to inhibition of cytochrome P450 3A metabolism of the alkaloids.

Dihydroergotamine has also been shown to be an inhibitor of cytochrome P450 3A catalyzed reactions and rare reports of ergotism have been obtained from patients treated with dihydroergotamine and macrolide antibiotics (e.g., clarithromycin, erythromycin), and in patients treated with dihydroergotamine and protease inhibitors (e.g., ritonavir), presumably due to inhibition of cytochrome P450 3A metabolism of ergotamine [see Contraindications (4) ].

BREKIYA can cause serious side effects, including: Serious problems with blood circulation to your legs and feet (peripheral ischemia) . BREKIYA can cause peripheral ischemia when you take it with certain medicines known as CYP3A4 inhibitors.

Peripheral ischemia may lead to a stroke and death. Stop taking BREKIYA and get emergency medical help right away if you have any of the following symptoms: cramping and pain in your legs or hips feeling of heaviness or tightness in your leg muscles burning or aching pain in your feet or toes while resting numbness, tingling, or weakness in your legs cold feeling or color changes in 1 or both legs or feet slurred speech sudden weakness Do not take medicines known as strong CYP3A4 inhibitors, such as: ritonavir indinavir clarithromycin itraconazole nelfinavir erythromycin ketoconazole These are not all of the medicines that could affect how BREKIYA works.

Your healthcare provider can tell you if it is safe to take BREKIYA with other medicines. What is BREKIYA? BREKIYA is a prescription medicine used for the acute treatment of migraine with or without aura and acute cluster headaches in adults.

BREKIYA is not used to prevent migraine. BREKIYA is not used to treat other types of headaches such as hemiplegic migraines (that make you unable to move on one side of your body) or basilar migraines (rare form of migraine with aura). It is not known if BREKIYA is safe and effective in children.

Who should not take BREKIYA? Do not use BREKIYA if you: are taking medicines known as strong CYP3A4 inhibitors. have heart problems or a history of heart problems. have uncontrolled high blood pressure. have narrowing of blood vessels in your legs, arms, stomach, or kidneys (peripheral vascular disease). have sepsis. have had vascular surgery. have severe liver problems. have severe kidney problems. are allergic to dihydroergotamine, ergot alkaloids, latex, or any of the ingredients in BREKIYA. See the end of this Medication Guide for a complete list of ingredients in BREKIYA. have taken any of the following medicines in the last 24 hours: sumatriptan almotriptan eletriptan frovatriptan naratriptan rizatriptan ergotamine or ergotamine-type medicines zolmitriptan have taken any medicines that constrict your blood vessels or raise your blood pressure.

Ask your healthcare provider if you are not sure if you are taking any of these medicines. Your healthcare provider can tell you if it is safe to take BREKIYA with other medicines.
