Clinical
Sumatriptan injection is used to treat the symptoms of migraine headaches (severe, throbbing headaches that sometimes come with nausea and a strong reaction to sound and light). Sumatriptan injection is also used to treat the symptoms of cluster headaches (severe headaches usually on one side of the head or around one eye). Sumatriptan is in a class of medications called selective serotonin receptor agonists. It works by narrowing blood vessels in the brain, stopping pain signals from being sent to the brain, and stops the release of certain natural substances that cause pain, nausea, and othe...

🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Sumatriptan injection is indicated in adults for (1) the acute treatment of migraine, with or without aura, and (2) the acute treatment of cluster headache. Limitations of Use : Use only if a clear diagnosis of migraine or cluster headache has been established. If a patient has no response to the first migraine or cluster headache attack treated with sumatriptan injection, reconsider the diagnosis before sumatriptan injection is administered to treat any subsequent attacks.
Sumatriptan injection is not indicated for the prevention of migraine or cluster headache attacks. Sumatriptan injection is a serotonin (5-HT 1B/1D ) receptor agonist (triptan) indicated for: Acute treatment of migraine with or without aura in adults (1) Acute treatment of cluster headache in adults (1) Limitations of Use: Use only if a clear diagnosis of migraine or cluster headache has been established. (1) Not indicated for the prophylactic therapy of migraine or cluster headache attacks (1)
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION For subcutaneous use only. (2.1) Acute treatment of migraine: single dose of 1 mg to 6 mg (2.1) Acute treatment of cluster headache: single dose of 6 mg (2.1) Maximum dose in a 24-hour period: 12 mg, separate doses by at least 1 hour. (2.1)
2.1Dosing Information The maximum single recommended adult dose of sumatriptan injection for the acute treatment of migraine or cluster headache is 6 mg injected subcutaneously. For the treatment of migraine, if side effects are dose limiting, the lower dose of 4 mg may be used [see Clinical Studies ( 14.1 )]. For the treatment of cluster headache, the efficacy of lower doses has not been established.
The maximum cumulative dose that may be given in 24 hours is 12 mg, two 6 mg injections separated by at least 1 hour. A second 6 mg dose should only be considered if some response to a first injection was observed.
2.2Administration Using the Sumatriptan Autoinjector An autoinjector device (sumatriptan autoinjector) is available for use with 6 mg prefilled syringe to facilitate self-administration in patients using the 6 mg dose. With this device, the needle penetrates approximately 1/4 inch (5 to 6 mm). The injection is intended to be given subcutaneously, and intramuscular or intravascular delivery must be avoided.
Instruct patients on the proper use of sumatriptan autoinjector and direct them to use injection sites with an adequate skin and subcutaneous thickness to accommodate the length of the needle.
💊 Dosage Forms and Strengths ▾
3 DOSAGE FORMS AND STRENGTHS Injection: 6 mg prefilled syringe assembled in an Autoinjector. Each 0.5 mL injection contains 8.4 mg of sumatriptan succinate, USP equivalent to 6 mg of sumatriptan. Injection: 6 mg single-dose prefilled syringe assembled in an autoinjector (3)

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Myocardial ischemia/infarction and Prinzmetal’s angina: Perform cardiac evaluation in patients with multiple cardiovascular risk factors. (5.1) Arrhythmias: Discontinue sumatriptan injection if occurs. (5.2) Chest/throat/neck/jaw pain, tightness, pressure, or heaviness: Generally not associated with myocardial ischemia; evaluate for coronary artery disease in patients at high risk.
(5.3) Cerebral hemorrhage, subarachnoid hemorrhage, and stroke: Discontinue sumatriptan injection if occurs. (5.4) Gastrointestinal ischemic reactions and peripheral vasospastic reactions: Discontinue sumatriptan injection if occurs. (5.5) Medication overuse headache: Detoxification may be necessary.
(5.6) Serotonin syndrome: Discontinue sumatriptan injection if occurs. (5.7) Seizures: Use with caution in patients with epilepsy or a lowered seizure threshold. (5.10)
5.1Myocardial Ischemia, Myocardial Infarction, and Prinzmetal’s Angina The use of sumatriptan injection is contraindicated in patients with ischemic or vasospastic CAD. There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few hours following administration of sumatriptan injection. Some of these reactions occurred in patients without known CAD.
Sumatriptan injection may cause coronary artery vasospasm (Prinzmetal’s angina), even in patients without a history of CAD. Perform a cardiovascular evaluation in triptan-naive patients who have multiple cardiovascular risk factors (e.g., increased age, diabetes, hypertension, smoking, obesity, strong family history of CAD) prior to receiving sumatriptan injection. If there is evidence of CAD or coronary artery vasospasm, sumatriptan injection is contraindicated.
For patients with multiple cardiovascular risk factors who have a negative cardiovascular evaluation, consider administering the first dose of sumatriptan injection in a medically supervised setting and performing an electrocardiogram (ECG) immediately following administration of sumatriptan injection. For such patients, consider periodic cardiovascular evaluation in intermittent long-term users of sumatriptan injection.
5.2Arrhythmias Life-threatening disturbances of cardiac rhythm, including ventricular tachycardia and ventricular fibrillation leading to death, have been reported within a few hours following the administration of 5-HT 1 agonists. Discontinue sumatriptan injection if these disturbances occur. Sumatriptan injection is contraindicated in patients with Wolff-Parkinson-White syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorders.
5.3Chest, Throat, Neck and /or Jaw Pain/Tightness/Pressure Sensations of tightness, pain, pressure, and heaviness in the precordium, throat, neck, and jaw commonly occur after treatment with sumatriptan injection and are usually non-cardiac in origin. However, perform a cardiac evaluation if these patients are at high cardiac risk. The use of sumatriptan injection is contraindicated in patients with CAD and those with Prinzmetal’s variant angina.
5.4Cerebrovascular Events Cerebral hemorrhage, subarachnoid hemorrhage, and stroke have occurred in patients treated with 5-HT 1 agonists, and some have resulted in fatalities. In a number of cases, it appears possible that the cerebrovascular events were primary, the 5-HT 1 agonist having been administered in the incorrect belief that the symptoms experienced were a consequence of migraine when they were not. Also, patients with migraine may be at increased risk of certain cerebrovascular events (e.g., stroke, hemorrhage, TIA).
Discontinue sumatriptan injection if a cerebrovascular event occurs. Before treating headaches in patients not previously diagnosed with migraine or cluster headache or in patients who present with atypical symptoms, exclude other potentially serious neurological conditions. Sumatriptan injection is contraindicated in patients with a history of…

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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. Migraine Headache Table 1 lists adverse reactions that occurred in 2 U.S. placebo-controlled clinical trials in patients with migraines (Studies 2 and 3) following either a single 6 mg dose of sumatriptan injection or placebo.
Only reactions that occurred at a frequency of 2% or more in groups treated with sumatriptan injection 6 mg and that occurred at a frequency greater than the placebo group are included in Table 1. Table 1. Adverse Reactions in Pooled Placebo-Controlled Trials in Patients with Migraine (Studies 2 and 3) Percent of Subjects Reporting Adverse Reaction Sumatriptan Injection 6 mg Subcutaneous (n = 547) % Placebo (n = 370) % Atypical sensations 42 9 Tingling 14 3 Warm/hot sensation 11 4 Burning sensation 7 <1 Feeling of heaviness 7 1 Pressure sensation 7 2 Feeling of tightness 5 <1 Numbness 5 2 Feeling strange 2 <1 Tight feeling in head 2 <1 Cardiovascular Flushing 7 2 Chest discomfort 5 1 Tightness in chest 3 <1 Pressure in chest 2 <1 Ear, nose, and throat Throat discomfort 3 <1 Discomfort: nasal cavity/sinuses 2 <1 Injection site reaction a 59 24 Miscellaneous Jaw discomfort 2 0 Musculoskeletal Weakness 5 <1 Neck pain/stiffness 5 <1 Myalgia 2 <1 Neurological Dizziness/vertigo 12 4 Drowsiness/sedation 3 2 Headache 2 <1 Skin Sweating 2 1 a Includes injection site pain, stinging/burning, swelling, erythema, bruising, bleeding.
The incidence of adverse reactions in controlled clinical trials was not affected by gender or age of the patients. There were insufficient data to assess the impact of race on the incidence of adverse reactions. Cluster Headache In the controlled clinical trials assessing the efficacy of sumatriptan injection as a treatment for cluster headache (Studies 4 and 5), no new significant adverse reactions were detected that had not already been identified in trials of sumatriptan injection in patients with migraine.
Overall, the frequency of adverse reactions reported in the trials of cluster headache was generally lower than in the migraine trials. Exceptions include reports of paresthesia (5% sumatriptan injection, 0% placebo), nausea and vomiting (4% sumatriptan injection, 0% placebo), and bronchospasm (1% sumatriptan injection, 0% placebo).
6.2Postmarketing Experience The following adverse reactions have been identified during postapproval use of sumatriptan tablets, sumatriptan nasal spray, and sumatriptan injection. Because these reactions are reported voluntarily from a population of unc…

7 DRUG INTERACTIONS
7.1Ergot-Containing Drugs Ergot-containing drugs have been reported to cause prolonged vasospastic reactions. Because these effects may be additive, use of ergotamine-containing or ergot-type medications (like dihydroergotamine or methysergide) and sumatriptan injection within 24 hours of each other is contraindicated.
7.2Monoamine Oxidase-A Inhibitors MAO-A inhibitors increase systemic exposure by 2-fold. Therefore, the use of sumatriptan injection in patients receiving MAO-A inhibitors is contraindicated [see Clinical Pharmacology ( 12.3)] .
7.3Other 5-HT 1 Agonists Because their vasospastic effects may be additive, co-administration of sumatriptan injection and other 5-HT 1 agonists (e.g., triptans) within 24 hours of each other is contraindicated.
7.4Selective Serotonin Reuptake Inhibitors/Serotonin Norepinephrine Reuptake Inhibitors and Serotonin Syndrome Cases of serotonin syndrome have been reported during coadministration of triptans and SSRIs, SNRIs, TCAs, and MAO inhibitors [see Warnings and Precautions (5.7 )].
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm (8.1)
8.1Pregnancy Risk Summary Data from a prospective pregnancy exposure registry and epidemiological studies of pregnant women have not detected an increased frequency of birth defects or a consistent pattern of birth defects among women exposed to sumatriptan compared with the general population (see Data). In developmental toxicity studies in rats and rabbits, oral administration of sumatriptan to pregnant animals was associated with embryolethality, fetal abnormalities, and pup mortality. When administered by the intravenous route to pregnant rabbits, sumatriptan was embryolethal (see Data).
In the U.S. general population, the estimated background risk of major birth defects and of miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. The reported rate of major birth defects among deliveries to women with migraine ranged from 2.2% to 2.9% and the reported rate of miscarriage was 17%, which were similar to rates reported in women without migraine. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk: Several studies have suggested that women with migraine may be at increased risk of preeclampsia during pregnancy.
Data Human Data: The Sumatriptan/Naratriptan/TREXIMET (sumatriptan and naproxen sodium) Pregnancy Registry, a population-based international prospective study, collected data for sumatriptan from January 1996 to September 2012. The Registry documented outcomes of 626 infants and fetuses exposed to sumatriptan during pregnancy (528 with earliest exposure during the first trimester, 78 during the second trimester, 16 during the third trimester, and 4 unknown). The occurrence of major birth defects (excluding fetal deaths and induced abortions without reported defects and all spontaneous pregnancy losses) during first-trimester exposure to sumatriptan was 4.2% (20/478 [95% CI: 2.6% to 6.5%]) and during any trimester of exposure was 4.2% (24/576 [95% CI: 2.7% to 6.2%]).
The sample size in this study had 80% power to detect at least a 1.73-to 1.91-fold increase in the rate of major malformations. The number of exposed pregnancy outcomes accumulated during the registry was insufficient to support definitive conclusions about overall malformation risk or for making comparisons of the frequencies of specific birth defects. Of the 20 infants with reported birth defects after exposure to sumatriptan in the first trimester, 4 infants had ventricular septal defects, including one infant who was exposed to both sumatriptan and naratriptan, and 3 infants had pyloric stenosis.
No other birth defect was reported for more than 2 infants in this group. In a study using data from the Swedish Medical Birth Register, live births to women who reported using triptans or ergots during pregnancy were compared with those of women who did not. Of the 2,257 births with first-trimester exposure to sumatriptan, 107 infants were born with malformations (relative risk 0.99 [95% CI: 0.91 to 1.21]).
A study using linked data from the Medical Birth Registry of Norway to the Norwegian Prescription Database compared pregnancy outcomes in women who redeemed prescriptions for triptans during pregnancy, as well as a migraine disease comparison group who redeemed prescriptions for sumatriptan before pregnancy only, compared with a population control group. Of the 415 women who redeemed prescriptions for sumatriptan during the first trimester, 15 had infants with major congenital malformations (OR 1.16 [95% CI: 0.69 to 1.94]) while for the 364 women who redeemed prescriptions for sumatriptan before, but not during, pregnancy, 20 had infants with major congenital malformations (OR 1.83 [95% CI: 1.17 to 2.88]), each compared with the population comparison group.

🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness in pediatric patients have not been established. Sumatriptan injection is not recommended for use in patients younger than 18 years of age. Two controlled clinical trials evaluated sumatriptan nasal spray (5 to 20 mg) in 1,248 pediatric migraineurs aged 12 to 17 years who treated a single attack.
The trials did not establish the efficacy of sumatriptan nasal spray compared with placebo in the treatment of migraine in pediatric patients. Adverse reactions observed in these clinical trials were similar in nature to those reported in clinical trials in adults. Five controlled clinical trials (2 single-attack trials, 3 multiple-attack trials) evaluating oral sumatriptan (25 to 100 mg) in pediatric patients aged 12 to 17 years enrolled a total of 701 pediatric migraineurs.
These trials did not establish the efficacy of oral sumatriptan compared with placebo in the treatment of migraine in pediatric patients. Adverse reactions observed in these clinical trials were similar in nature to those reported in clinical trials in adults. The frequency of all adverse reactions in these patients appeared to be both dose- and age-dependent, with younger patients reporting reactions more commonly than older pediatric patients.
Postmarketing experience documents that serious adverse reactions have occurred in the pediatric population after use of subcutaneous, oral, and/or intranasal sumatriptan. These reports include reactions similar in nature to those reported rarely in adults, including stroke, visual loss, and death. A myocardial infarction has been reported in a 14-year-old male following the use of oral sumatriptan; clinical signs occurred within 1 day of drug administration.
Clinical data to determine the frequency of serious adverse reactions in pediatric patients who might receive subcutaneous, oral, or intranasal sumatriptan are not presently available.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical trials of sumatriptan injection did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. 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.
A cardiovascular evaluation is recommended for geriatric patients who have other cardiovascular risk factors (e.g., diabetes, hypertension, smoking, obesity, strong family history of CAD) prior to receiving sumatriptan injection [see Warnings and Precautions ( 5.1 )].
🆘 Overdosage ▾
10 OVERDOSAGE Coronary vasospasm was observed after intravenous administration of sumatriptan injection [see Contraindications ( 4 )] . Overdoses would be expected from animal data (dogs at 0.1 g/kg, rats at 2 g/kg) to possibly cause convulsions, tremor, inactivity, erythema of the extremities, reduced respiratory rate, cyanosis, ataxia, mydriasis, injection site reactions (desquamation, hair loss, and scab formation), and paralysis. The elimination half-life of sumatriptan is about 2 hours [ see Clinical Pharmacology (12.3) ] ; therefore, monitoring of patients after overdose with sumatriptan injection should continue for at least 10 hours or while symptoms or signs persist.
It is unknown what effect hemodialysis or peritoneal dialysis has on the serum concentrations of sumatriptan.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Sumatriptan binds with high affinity to human cloned 5-HT 1B/1D receptors. Sumatriptan presumably exerts its therapeutic effects in the treatment of migraine and cluster headaches through agonist effects at the 5-HT 1B/1D receptors on intracranial blood vessels and sensory nerves of the trigeminal system, which result in cranial vessel constriction and inhibition of pro-inflammatory neuropeptide release.
12.2Pharmacodynamics Blood Pressure Significant elevation in blood pressure, including hypertensive crisis, has been reported in patients with and without a history of hypertension [see Warnings and Precautions ( 5.8 )] . Peripheral (Small) Arteries In healthy volunteers (N = 18), a trial evaluating the effects of sumatriptan on peripheral (small vessel) arterial reactivity failed to detect a clinically significant increase in peripheral resistance. Heart Rate Transient increases in blood pressure observed in some patients in clinical trials carried out during sumatriptan’s development as a treatment for migraine were not accompanied by any clinically significant changes in heart rate.
12.3Pharmacokinetics Absorption The bioavailability of sumatriptan via subcutaneous site injection to 18 healthy male subjects was 97% ± 16% of that obtained following intravenous injection. After a single 6 mg subcutaneous manual injection into the deltoid area of the arm in 18 healthy males (age: 24 ± 6 years, weight: 70 kg), the maximum serum concentration (C max ) of sumatriptan was (mean ± standard deviation) 74 ± 15 ng/mL and the time to peak concentration (T max ) was 12 minutes after injection (range: 5 to 20 minutes).
In this trial, the same dose injected subcutaneously in the thigh gave a C max of 61 ± 15 ng/mL by manual injection versus 52 ±15 ng/mL by autoinjector techniques. The T max or amount absorbed was not significantly altered by either the site or technique of injection. Distribution Protein binding, determined by equilibrium dialysis over the concentration range of 10 to 1,000 ng/mL is low, approximately 14% to 21%.
The effect of sumatriptan on the protein binding of other drugs has not been evaluated. Following a 6 mg subcutaneous injection into the deltoid area of the arm in 9 males (mean age: 33 years, mean weight: 77 kg) the volume of distribution central compartment of sumatriptan was 50 ± 8 liters and the distribution half-life was 15± 2 minutes. Metabolism In vitro studies with human microsomes suggest that sumatriptan is metabolized by MAO, predominantly the A isoenzyme.
Most of a radiolabeled dose of sumatriptan excreted in the urine is the major metabolite indole acetic acid (IAA) or the IAA glucuronide, both of which are inactive. Elimination After a single 6 mg subcutaneous dose, 22% ± 4% was excreted in the urine as unchanged sumatriptan and 38% ± 7% as the IAA metabolite. Following a 6 mg subcutaneous injection into the deltoid area of the arm, the systemic clearance of sumatriptan was 1,194 ± 149 mL/min and the terminal half-life was 115 ± 19 minutes.
Specific Populations Age :The pharmacokinetics of sumatriptan in the elderly (mean age: 72 years, 2 males and 4 females) and in subjects with migraine (mean age: 38 years, 25 males and 155 females) were similar to that in healthy male subjects (mean age: 30 years). Patients with Hepatic Impairment: The effect of mild to moderate hepatic disease on the pharmacokinetics of subcutaneously administered sumatriptan has been evaluated. There were no significant differences in the pharmacokinetics of subcutaneously administered sumatriptan in moderately hepatically impaired subjects compared with healthy controls.
The pharmacokinetics of subcutaneously administered sumatriptan in patients with severe hepatic impairment has not been studied. The use of sumatriptan injection in this population is contraindicated [see Contraindications (4) ]. Racial Groups: The systemic clearance and C max of subcutaneous sumatriptan were…
🧬 Mechanism of Action ▾
12.1Mechanism of Action Sumatriptan binds with high affinity to human cloned 5-HT 1B/1D receptors. Sumatriptan presumably exerts its therapeutic effects in the treatment of migraine and cluster headaches through agonist effects at the 5-HT 1B/1D receptors on intracranial blood vessels and sensory nerves of the trigeminal system, which result in cranial vessel constriction and inhibition of pro-inflammatory neuropeptide release.

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use). Risk of Myocardial Ischemia and/or Infarction, Prinzmetal’s Angina, Other Vasospasm-Related Events, Arrhythmias, and Cerebrovascular Events Inform patients that sumatriptan injection may cause serious cardiovascular side effects such as myocardial infarction or stroke. Although serious cardiovascular events can occur without warning symptoms, patients should be alert for the signs and symptoms of chest pain, shortness of breath, irregular heartbeat, significant rise in blood pressure, weakness, and slurring of speech and should ask for medical advice if any indicative sign or symptoms are observed.
Apprise patients of the importance of this follow-up [see Warnings and Precautions ( 5.1 , 5.2 , 5.4 , 5.5 , 5.8 )] . Hypersensitivity Reactions Inform patients that anaphylactic reactions have occurred in patients receiving sumatriptan injection. Such reactions can be life-threatening or fatal.
In general, anaphylactic reactions to drugs are more likely to occur in individuals with a history of sensitivity to multiple allergens [see Contraindications (4) , Warnings and Precautions (5.9) ]. Concomitant Use with Other Triptans or Ergot Medications Inform patients that use of sumatriptan injection within 24 hours of another triptan or an ergot-type medication (including dihydroergotamine or methysergide) is contraindicated [see Contraindications (4) , Drug Interactions ( 7.1 , 7.3 )] . Serotonin Syndrome Caution patients about the risk of serotonin syndrome with the use of sumatriptan injection or other triptans, particularly during combined use with SSRIs, SNRIs, TCAs, and MAO inhibitors [see Warnings and Precautions (5.7) , Drug Interactions (7.4) ] .
Medication Overuse Headache Inform patients that use of acute migraine drugs for 10 or more days per month may lead to an exacerbation of headache and encourage patients to record headache frequency and drug use (e.g., by keeping a headache diary) [see Warnings and Precautions (5.6) ]. Pregnancy Advise patients to notify their healthcare provider if they become pregnant during treatment or plan to become pregnant [see Use in Specific Populations ( 8.1 )]. Lactation Advise breastfeeding women that they may develop transient breast pain when taking sumatriptan injection.
Advise breastfeeding women that avoiding breastfeeding for 12 hours after treatment with sumatriptan injection can minimize their infant’s exposure to sumatriptan [see Use in Specific Populations (8.2) ] . Ability to Perform Complex Tasks Treatment with sumatriptan injection may cause somnolence and dizziness; instruct patients to evaluate their ability to perform complex tasks after administration of sumatriptan injection. How to Use Sumatriptan Injection Instruct patients to read the Instructions for Use before starting therapy.
Provide patients instruction on the proper use of sumatriptan injection if they are able to self-administer sumatriptan injection in medicaly unsupervised situations. Instruct patients on storage and disposal of the pen [see How Supplied/Storage and Handling ( 16 )]. Inform patients that the needle in the sumatriptan autoinjector penetrates approximately 1/4 of an inch (5 to 6 mm).
Inform patients that the injection is intended to be given subcutaneously and intramuscular or intravascular delivery should be avoided.
