⏳ Availability & generic status
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.
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.
🛈 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.

🚨 Boxed Warning ▾
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 ATZUMI with strong CYP3A4 inhibitors is contraindicated [see Contraindications (4) , Warnings and Precautions (5.1) , and Drug Interactions (7.1) ].

⛔ Contraindications ▾
4 CONTRAINDICATIONS ATZUMI is contraindicated in patients: with concomitant use of strong CYP3A4 inhibitors [see Warnings and Precautions (5.1) and Drug Interactions (7.1) ] with ischemic heart disease (e.g., angina pectoris, history of myocardial infarction, or documented silent ischemia) or patients who have clinical symptoms or findings consistent with coronary artery vasospasm, including Prinzmetal's variant angina [see Warnings and Precautions (5.4) ] with uncontrolled hypertension [see Warnings and Precautions (5.5) ] with peripheral arterial disease with sepsis following vascular surgery with severe hepatic impairment with severe renal impairment with known hypersensitivity to ergot alkaloids with recent use (i.e., within 24 hours) of other 5-HT 1 agonists or ergotamine-containing or ergot-type medications [see Drug Interactions (7.2) ] with concomitant use of peripheral and central vasoconstrictors because the combination may result in additive or synergistic elevation of blood pressure [see Warnings and Precautions (5.5) ] Concomitant use of strong CYP3A4 inhibitors.
( 4 ) Ischemic heart disease or coronary artery vasospasm ( 4 ) Uncontrolled hypertension, peripheral arterial diseases, sepsis, following vascular surgery, or severe hepatic or renal impairment ( 4 ) Hypersensitivity to ergot alkaloids ( 4 ) Concomitant use of other 5-HT 1 agonists or ergotamine-containing or ergot-type medications within 24 hours ( 4 ) Concomitant use of peripheral and central vasoconstrictors ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Myocardial Ischemia and/or Infarction, Other Cardiac Adverse Reactions, and Fatalities: In patients with risk factors predictive of coronary artery disease, consider first dose administration under medical supervision with electrocardiogram. ( 5.2 ) Cerebrovascular Adverse Reactions and Fatalities: Cerebral hemorrhage, subarachnoid hemorrhage, and stroke have been reported; discontinue ATZUMI if suspected. ( 5.3 ) Other Vasospasm Related Adverse Reactions: ATZUMI may cause vasospasm or elevation in blood pressure.
Discontinue if signs or symptoms of vasoconstriction develop. ( 5.4 , 5.5 ) Medication Overuse Headache: Detoxification may be necessary. ( 5.6 ) Preterm Labor: Advise pregnant women of the risk.
( 5.7 , 8.1 ) Fibrotic Complications: Pleural and retroperitoneal fibrosis have been reported following prolonged daily use of dihydroergotamine. Administration of ATZUMI should not exceed the dosing guidelines or be used for chronic daily administration. ( 5.8 ) Local Irritation: If severe local irritation occurs for no other attributable reason, suspend ATZUMI until resolution.
( 5.9 )
5.1Peripheral 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, including protease inhibitors, macrolide antibiotics, and antifungals. 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 ATZUMI 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 ATZUMI treatment. Serious adverse cardiac events, including some that have been fatal, have occurred following use of dihydroergotamine. 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 ATZUMI, 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, ATZUMI 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 ATZUMI 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 ATZUMI, 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 adverse reactions exists with ATZUMI treatment. Cerebral hemorrhage, subarachnoid hemorrhage, stroke, and other cerebrovascular events have been reported in patients treated with dihydroergotamine; and some have resulted in fatalities. In a number of cases, it appears possible that the cerebrovascular events were primary, the dihydroergotamine having been administered in the inco…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The studies described below were conducted with dihydroergotamine mesylate nasal spray; adverse reactions with ATZUMI nasal powder are expected to be similar to adverse reactions with dihydroergotamine mesylate nasal spray. Adverse Reactions in Placebo-Controlled Trials with Dihydroergotamine Mesylate Nasal Spray [see Clinical Studies (14) ] Of the 1,796 patients and subjects treated with dihydroergotamine mesylate nasal spray doses 2 mg or less in U.S. and foreign clinical studies, 26 (1.4%) discontinued because of adverse events.
The adverse events associated with discontinuation were, in decreasing order of frequency: rhinitis (13), dizziness (2), facial edema (2), and one patient each due to cold sweats, accidental trauma, depression, elective surgery, somnolence, allergy, vomiting, hypotension, and paraesthesia. Table 1 summarizes the incidence rates of adverse reactions reported by at least 1% of patients who received dihydroergotamine mesylate nasal spray for the treatment of migraine during placebo-controlled, double-blind clinical studies and were more frequent than in those patients receiving placebo.
The most commonly reported adverse reactions (greater than 1% of patients who received dihydroergotamine mesylate nasal spray) were rhinitis, nausea, altered sense of taste, application site reactions, dizziness, vomiting, somnolence, pharyngitis, and diarrhea. In most instances these events were transient and self-limited and did not result in patient discontinuation from a study.

🔄 Drug Interactions ▾
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 ATZUMI 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 effects could be additive with ATZUMI. Therefore, triptans and ATZUMI 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 ATZUMI 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 (5.2 , 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 (e.g., fluoxetine, fluvoxamine, paroxetine, sertraline).
👥 Use in Specific Populations ▾
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 ATZUMI, use during pregnancy. Avoid use of ATZUMI 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 during pregnancy.
In animal reproduction studies, adverse effects on development were observed following intranasal 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 ) . 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.
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. 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 and greater.
A no-effect level for adverse effects on embryofetal development 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 development 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 effects on pre- and postnatal development in rats was not established. Effects on offspring development occurred at doses below those that produced evidence of significant 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 present in human milk. There are reports of diarrhea, vomiting, weak pulse, and unstable blood pressure in breastfed infants exposed to ergotamine. ATZUMI 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 ATZUMI and for 3 days after the last dose. Breast milk supply during this time should be pumped and discarded.
8.4Pediatric Use The safety and effectiveness of ATZUMI have not been established in pediatric patients.
8.5Geriatric Use Clinical studies of ATZUMI and other 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 e…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of ATZUMI have not been established in pediatric patients.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of ATZUMI and other 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 of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE
10.1Symptoms Excessive doses of dihydroergotamine may result in peripheral signs and symptoms of ergotism. In general, the symptoms of an acute ATZUMI overdose may be similar to those of an ergotamine overdose, although there may be less pronounced nausea and vomiting with ATZUMI. 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 mesylate was lethal when given at intravenous doses of 44 mg/kg in mice, 130 mg/kg in rats, and 37 mg/kg in rabbits.
10.2Treatment Treatment of an overdose of ATZUMI should consist of discontinuation of the drug, general supportive measures including monitoring of vital signs, and observation of the clinical status of the patient for at least 24 hours, or while symptoms or signs persist.

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 [see Warnings and Precautions (5.7) ] .
12.3Pharmacokinetics Absorption Following ATZUMI administration, the mean maximum plasma concentration was 2.1 ng/mL, and the median time from dosing to maximum plasma concentration was approximately 0.5 hours. Distribution Dihydroergotamine is 93% plasma protein bound. The apparent steady-state volume of distribution is approximately 800 liters.
Elimination The mean apparent half-life of dihydroergotamine following nasal administration of ATZUMI in healthy subjects is approximately 13 hours. 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 1 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 of ATZUMI, the 8'-β-hydroxydihydroergotamine metabolite plasma AUC was approximately 16% of the plasma AUC of dihydroergotamine, and the mean C max (5.7% of parent) was below the minimal concentrations required for receptor binding for adrenergic and 5-HT 1 receptors. Excretion The major excretory route of dihydroergotamine is via the bile in the feces.
The total body clearance following ATZUMI administration is
1.5L/min which reflects mainly hepatic clearance. The renal clearance (0.1 L/min) is unaffected by the route of dihydroergotamine administration based on other dihydroergotamine products. Specific Populations No studies have been conducted on the effect of renal or hepatic impairment, gender, race, ethnicity, or pregnancy on dihydroergotamine pharmacokinetics [see Contraindications (4) , Use in Specific Populations (8.1) ] .
Drug Interaction Studies CYP3A4 Inhibitors In a drug interaction study, administration of ATZUMI with itraconazole increased dihydroergotamine plasma exposure by 14% for C max and 19% for AUC while the plasma exposures (C max and AUC 0-inf ) of 8'-β-hydroxy dihydroergotamine (8'-OH-DHE, active metabolite) were increased by approximately 4-fold and 3-fold, respectively [see Contraindications (4) , Warnings and Precautions (5.1) , Drug Interactions (7.1) ] . Other Drugs The pharmacokinetics of dihydroergotamine did not appear to be significantly affected by the concomitant use of a local vasoconstrictor.
Multiple oral doses of the β-adrenoceptor antagonist propranolol, used for preventive treatment of migraine, had no significant influence on the C max , T max or AUC of dihydroergotamine doses up to 4 mg [see Drug Interactions (7.3) ]. The effect of oral contraceptives on the pharmacokinetics of dihydroergotamine has not been studied.
