🩺 Clinical
Zavegepant nasal spray is used to treat the symptoms of migraine headaches (severe, throbbing headaches, sometimes occurring with nausea and sensitivity to sound or light). Zavegepant is in a class of medications called calcitonin gene-related peptide receptor antagonists. It works by blocking the action of a certain natural substance in the body that causes migraine headaches. Zavegepant does not prevent migraine attacks.

⏳ 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.

⛔ Contraindications ▾
4 CONTRAINDICATIONS ZAVZPRET is contraindicated in patients with a history of hypersensitivity reaction to zavegepant or any of the components of ZAVZPRET. Reactions have included anaphylaxis [see Warnings and Precautions (5.1) ] . Patients with a history of hypersensitivity reaction to zavegepant or to any of the components of ZAVZPRET. ( 4 )
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Hypersensitivity Reactions: If a serious hypersensitivity reaction occurs, discontinue ZAVZPRET and initiate appropriate therapy. Hypersensitivity reactions including anaphylaxis, facial swelling, and urticaria, have occurred with ZAVZPRET. ( 5.1 ) • Hypertension: New-onset or worsening of pre-existing hypertension may occur.
( 5.2 ) • Raynaud’s Phenomenon: New-onset or worsening of pre-existing Raynaud’s phenomenon may occur. ( 5.3 )
5.1Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis, facial swelling, and urticaria, have occurred in patients treated with ZAVZPRET. If a hypersensitivity reaction occurs, discontinue ZAVZPRET and initiate appropriate therapy [see Contraindications (4) and Adverse Reactions (6.1 , 6.2) ].
5.2Hypertension Development of hypertension and worsening of pre-existing hypertension have been reported following the use of CGRP antagonists in the postmarketing setting. Some of the patients receiving a CGRP antagonist who developed new-onset hypertension had risk factors for hypertension. There were cases requiring initiation of pharmacological treatment for hypertension and, in some cases, hospitalization.
Hypertension may occur at any time during treatment, but was most frequently reported within 7 days of therapy initiation. The CGRP antagonist was discontinued in many of the reported cases. Monitor patients treated with ZAVZPRET for new-onset hypertension or worsening of pre-existing hypertension, and consider whether discontinuation of ZAVZPRET is warranted if evaluation fails to establish an alternative etiology or blood pressure is inadequately controlled.
5.3Raynaud’s Phenomenon Development of Raynaud’s phenomenon and recurrence or worsening of pre-existing Raynaud’s phenomenon have been reported in the postmarketing setting following the use of CGRP antagonists. In reported cases with small molecule CGRP antagonists, symptom onset occurred a median of 1.5 days following dosing. Many of the cases reported serious outcomes, including hospitalizations and disability, generally related to debilitating pain.
In most reported cases, discontinuation of the CGRP antagonist resulted in resolution of symptoms. ZAVZPRET should be discontinued if signs or symptoms of Raynaud’s phenomenon develop, and patients should be evaluated by a healthcare provider if symptoms do not resolve. Patients with a history of Raynaud’s phenomenon should be monitored for, and informed about the possibility of, worsening or recurrence of signs and symptoms.
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The following clinically significant adverse reactions are discussed in greater detail in other sections of the labeling: • Hypersensitivity Reactions [see Warnings and Precautions (5.1) ] • Hypertension [see Warnings and Precautions (5.2) ] • Raynaud’s Phenomenon [see Warnings and Precautions (5.3) ] Most common adverse reactions (at least 2% of patients treated with ZAVZPRET and greater than placebo) were taste disorders, nausea, nasal discomfort, and vomiting. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch .
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 clinical practice. The safety of ZAVZPRET for the acute treatment of migraine in adults has been evaluated in two randomized, double-blind, placebo-controlled trials (Study 1 and Study 2) in patients with migraine who received one 10 mg dose of ZAVZPRET nasal spray (N=1023) or placebo (N=1056) [see Clinical Studies (14) ] .
Approximately 83% were female, 81% were White, 20% were Hispanic or Latino, and 15% were Black. The mean age at study entry was 41 years (range 18-79 years of age). Adverse reactions in Study 1 and 2 are shown in Table 1.
Table 1: Adverse Reactions Occurring in At Least 2% of Patients Treated with ZAVZPRET and at a Frequency Greater than Placebo in Study 1 and 2 Adverse Reaction ZAVZPRET N=1023 % Placebo N=1056 % Taste Disorders Taste disorders includes dysgeusia and ageusia 18 4 Nausea 4 1 Nasal Discomfort 3 1 Vomiting 2 <1 Hypersensitivity, including facial swelling and urticaria, occurred in less than 1% of patients treated with ZAVZPRET [see Contraindications (4) and Warnings and Precautions (5.1) ]. Long-term safety was assessed in an open-label extension study.
That study evaluated 603 patients, dosing intermittently for up to one year, including 360 patients who were exposed to ZAVZPRET 10 mg for at least 6 months, and 298 who were exposed for at least one year, all of whom treated an average of at least two migraine attacks per month.
6.2Postmarketing Experience The following adverse reactions have been identified during postapproval use of ZAVZPRET. 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 drug exposure. Immune System Disorders: Hypersensitivity (e.g., anaphylaxis) [see Contraindications (4) and Warnings and Precautions (5.1) ] Vascular Disorders : Hypertension [see Warnings and Precautions (5.2) ] , Raynaud’s phenomenon [see Warnings and Precautions (5.3) ]
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS • Avoid use with drugs that inhibit OATP1B3 or NTCP transporters. ( 7.1 ) • Avoid use with drugs that induce OATP1B3 or NTCP transporters. ( 7.2 ) • Avoid use of intranasal decongestants; if unavoidable, administer intranasal decongestants at least 1 hour after ZAVZPRET administration. ( 7.3 )
7.1OATP1B3 or NTCP Inhibitors Concomitant administration of ZAVZPRET with inhibitors of the organic anion transporting polypeptide 1B3 (OATP1B3) or sodium taurocholate co-transporting polypeptide (NTCP) transporters may result in a significant increase in zavegepant exposure.

7.2OATP1B3 or NTCP Inducers Concomitant administration of ZAVZPRET with inducers of OATP1B3 or NTCP transporters may result in a decrease in zavegepant exposure. Avoid concomitant administration of ZAVZPRET with drugs that induce OATP1B3 or NTCP transporters [see Clinical Pharmacology (12.3) ] .
7.3Intranasal Decongestants Concomitant administration of ZAVZPRET with intranasal decongestants may decrease the absorption of zavegepant. Avoid concomitant administration of intranasal decongestants with ZAVZPRET. When concomitant use is unavoidable, intranasal decongestants should be administered at least 1 hour after ZAVZPRET administration [see Clinical Pharmacology (12.3) ] .
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS • Avoid use in patients with severe hepatic impairment. ( 8.6 ) • Avoid use in patients with CLcr < 30 mL/min. ( 8.7 )
8.1Pregnancy Risk Summary There are no adequate data on the developmental risk associated with the use of ZAVZPRET in pregnant women. No adverse developmental effects were observed following subcutaneous administration of zavegepant to pregnant animals at doses associated with plasma exposures higher than those used clinically (see Data ) . In the U.S. general population, the estimated background risk of major birth defects and miscarriage 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 Subcutaneous administration of zavegepant to pregnant rats (0, 10, 20, or 40 mg/kg/day) or rabbits (0, 20, 40, or 60 mg/kg/day) during the period of organogenesis resulted in no adverse effects on embryofetal development.
Plasma exposures (AUC) at the highest doses tested were approximately 4000 times that in humans at the maximum recommended human dose (MRHD) of 10 mg/day. Subcutaneous administration of zavegepant (0, 5, 10, or 20 mg/kg/day) to rats throughout pregnancy and lactation resulted in no adverse effects on pre- and postnatal development. Plasma exposure (AUC) at the highest dose tested was approximately 2500 times that in humans at the MRHD.
8.2Lactation There are no data on the presence of zavegepant or its metabolites in human milk, the effects of zavegepant on the breastfed infant, or the effects of zavegepant on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ZAVZPRET and any potential adverse effects on the breastfed infant from ZAVZPRET or from the underlying maternal condition.
8.4Pediatric Use Safety and effectiveness in pediatric patients have not been established.
8.5Geriatric Use Clinical studies of ZAVZPRET did not include sufficient numbers of patients 65 years of age and older to determine whether they respond differently from younger adult patients. In a limited number of patients 65 years of age and older, no clinically significant pharmacokinetic differences were observed between elderly and younger subjects.
8.6Hepatic Impairment No dosage adjustment of ZAVZPRET is necessary in patients with mild hepatic impairment (Child-Pugh Class A) or moderate hepatic impairment (Child-Pugh Class B). ZAVZPRET has not been studied in patients with severe hepatic impairment (Child-Pugh Class C). Avoid use of ZAVZPRET in patients with severe hepatic impairment [see Clinical Pharmacology (12.3) ] .
8.7Renal Impairment No dosage adjustment of ZAVZPRET is necessary in patients with estimated creatine clearance (CLcr) 30 mL/min or greater. Avoid use of ZAVZPRET in patients with CLcr less than 30 mL/min [see Clinical Pharmacology (12.3) ] .

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Zavegepant is a calcitonin gene-related peptide (CGRP) receptor antagonist.
12.2Pharmacodynamics The relationship between pharmacodynamic activity and the mechanism by which zavegepant exerts its clinical effects is unknown. No clinically relevant differences in resting blood pressure were observed when zavegepant was concomitantly administered with sumatriptan (12 mg subcutaneous, given as two 6 mg doses separated by one hour) compared with sumatriptan alone to healthy volunteers. Cardiac Electrophysiology At a dose up to 4 times the recommended daily dose, zavegepant does not prolong the QT interval to any clinically relevant extent.
12.3Pharmacokinetics Absorption Peak plasma concentration of zavegepant was observed at approximately 30 minutes after a single 10 mg dose of the nasal spray. After nasal spray administration of zavegepant, the absolute bioavailability is approximately 5%. Zavegepant given as a single dose of the nasal spray displays slightly less than dose-proportional pharmacokinetics up to 40 mg (approximately 4 times the recommended dosage of 10 mg).
Following once daily dosing of ZAVZPRET for 14 days there was no evidence of zavegepant accumulation. Distribution The mean apparent volume of distribution of intranasal zavegepant is approximately 1774 L. Plasma protein binding of zavegepant is approximately 90%.
Elimination Metabolism Zavegepant is primarily metabolized by CYP3A4 and to a lesser extent by CYP2D6, in vitro. After single IV dose of 5 mg [ 14 C]-zavegepant, unchanged zavegepant was the most prevalent (approximately 90%) circulating component in the human plasma. No major metabolites (i.e., greater than 10%) of zavegepant were detected in plasma.
Excretion The effective half-life of zavegepant following a 10 mg dose of the nasal spray is 6.55 hours. The mean apparent clearance of intranasal zavegepant is 266 L/h. Zavegepant is excreted mostly via the biliary/fecal route, while the renal route is a minor route of elimination.
Following a single intravenous dose of 5 mg [ 14 C]-zavegepant to healthy male subjects, approximately 80% and 11% of the dose was recovered as unchanged zavegepant in feces and urine, respectively. Specific Populations Patients with Hepatic Impairment In a dedicated clinical study comparing the pharmacokinetics of zavegepant in subjects with moderate hepatic impairment (Child-Pugh B) to that of normal subjects (matched healthy controls), zavegepant C max was 16% higher and AUC was 1.9-fold higher in patients with moderate hepatic impairment.
These changes in exposures are not expected to be clinically significant, based on clinical safety experience and minimal accumulation of drug exposures. The impact of severe hepatic impairment (Child-Pugh C) on the pharmacokinetics of zavegepant was not studied [see Use in Specific Populations (8.6) ] . Patients with Renal Impairment The renal route plays a minor role in the clearance of zavegepant.
No clinically significant effect on the pharmacokinetics of zavegepant is expected in subjects with estimated creatinine clearance (CLcr) 30 mL/min or greater. In patients with CLcr 15 to 29 mL/min, accumulation of uremic solutes can cause an increase in zavegepant exposures by inhibiting OATP transporters. Zavegepant has not been studied in patients with CLcr less than 15 mL/min [see Use in Specific Populations (8.7) ] .
Other Specific Populations Age, sex, race, ethnicity, and body weight did not show clinically significant effects on the pharmacokinetics of zavegepant. Drug Interaction Studies In Vitro Studies Enzymes Zavegepant is a substrate of CYP3A4 and to a lesser extent CYP2D6. Zavegepant is not an inducer of CYP1A2, 2B6, or 3A4, or an inhibitor of CYP1A2, CYP2C9, 2C19, 2B6, 2D6, 2C8, and 3A4 at clinically relevant concentrations.
Transporters Zavegepant is a substrate for OATP1B3 and NTCP (see In Vivo studies ) . Zavegepant is also a substrate for the transporters P-gp, MATE1, and…
