Cautions
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
Equally effective at any stage of migraine, although early use recommended
Overuse of acute migraine drugs (eg, ergotamine, triptans, opioids, or combination of these drugs for ≥10 days/month) may lead to exacerbation of headache (medication overuse headache); detoxification may be necessary
Binds to melanin, may cause toxicity to melanin-rich tissues on prolonged use
Very rare reports of transient and permanent blindness and significant partial vision loss
Serotonin syndrome may occur, particularly during combined use with SSRIs (eg, fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram) or SNRIs (eg, venlafaxine, duloxetine); discontinue therapy if it occurs
Cerebral/subarachnoid hemorrhage and stroke reported with 5-HT1 agonist administration; discontinue if it occurs
Significant elevation of blood pressure, including hypertensive crisis, reported
Not for administration to patients with risk factors for coronary artery disease
Use caution in patients with history of seizure disorder or lowered seizure threshold
May cause depression including dizziness, weakness, or drowsiness (infrequent); caution when operating heavy machinery
Coronary artery vasospasm, transient ischemia, ventricular tachycardia/fibrillation, myocardial infarction, cardiac arrest and death reported with use 5HT1 agonists; perform cardiac evaluation in patients with multiple cardiovascular risk factors; evaluate for coronary artery disease in patients at high risk; discontinue therapy if arrhythmia occurs
Use oral formulations with caution in patients with mild-to-moderate hepatic impairment if treatment necessary and advisable; presystemic clearance, when administered orally, is reduced in hepatic impairment and cause an increase in plasma concentrations; dose reduction recommended; when adminsitered parenterally (SC, intranasal), does not undergo first pass metabolism and may not cause increase in plasma concentrations
Hypersensitivity reactions, including angioedema and anaphylaxis, reported; needle shield of prefilled syringe contains dry natural rubber (a latex derivative) that has potential to cause allergic reactions in latex-sensitive individuals
Pregnancy & Lactation
Pregnancy
Data from a prospective pregnancy exposure registry and epidemiological studies of pregnant women have not detected increased frequency of birth defects or consistent pattern of birth defects among women exposed to sumatriptan compared with general population; 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 intravenous route to pregnant rabbits, sumatriptan was embryolethal
However, possible disease-associated maternal and/or embryo/fetal risk reported; several studies have suggested that women with migraine may be at increased risk of preeclampsia during pregnancy
Lactation
Sumatriptan is excreted in human milk following subcutaneous administration; there are no data on effects of sumatriptan on breastfed infant or effects of sumatriptan on milk production; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for injection and any potential adverse effects on breastfed infant from sumatriptan or from underlying maternal condition
Infant exposure to sumatriptan can be minimized by avoiding breastfeeding for 12 hr after therapy
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

SUMATRIPTAN SPRAY - NASAL
(SOO-ma-TRIP-tan)
COMMON BRAND NAME(S): Imitrex, Tosymra
USES: Sumatriptan is used to treat migraines. It helps to relieve headache, pain, and other migraine symptoms (including nausea, vomiting, sensitivity to light/sound). Prompt treatment helps you return to your normal routine and may decrease your need for other pain medications. Sumatriptan belongs to a class of drugs known as triptans. It affects a certain natural substance (serotonin) that causes narrowing of blood vessels in the brain. It may also relieve pain by affecting certain nerves in the brain.Sumatriptan does not prevent future migraines or lessen how often you get migraine attacks.
HOW TO USE: Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start using sumatriptan spray and each time you get a refill. This medication comes in different brands with different strengths. Carefully read and follow the instructions for your brand. If you have any questions, ask your doctor or pharmacist.This product is for use in the nose only. Remove the sumatriptan spray from the package only when you are ready to use it. Do not test or prime the spray before use. Doing so will make you lose the dose.Use this medication at the first sign of a migraine as directed by your doctor, usually 1 spray into one nostril. Avoid spraying into your eyes. Gently blow your nose before using this medication. Keeping your head upright, close one nostril by pressing with your index finger on one side of your nose. You may tilt your head back slightly to keep the medicine from dripping out of your nose. Place the nozzle of the spray device into the other nostril and breathe in gently as you press the plunger. Keep your head upright, remove the nozzle from your nose, and gently breathe in through your nose and out through your mouth for 10 to 20 seconds. Your nose may feel wet inside and you may notice a slight taste after using the spray. This is normal.If there is no improvement in your symptoms, do not take more doses of this medication before talking to your doctor. If your symptoms are only partly relieved, or if your headache comes back, you may use another dose after at least 1 or at least 2 hours (depending on your brand). The dosage is based on your medical condition and response to treatment.If you have a higher risk for heart problems (see Precautions), your doctor may perform a heart exam before you start taking sumatriptan. He/she may also direct you to take your first dose of this medication in the office/clinic to monitor for serious side effects (such as chest pain). Talk to your doctor for details.If you are using drugs for migraine attacks on 10 or more days each month, the drugs may actually make your headaches worse (medication overuse headache). Do not use medications more often or for longer than directed. Tell your doctor if you need to use this medication more often, or if the medication is not working as well, or if your headaches get worse.
SIDE EFFECTS: Unusual taste or irritation/numbness/tingling of the nose or throat may occur after using the spray. Flushing, feelings of tingling/numbness/prickling/heat, tiredness, weakness, drowsiness, or dizziness may also occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.Tell your doctor right away if you have any serious side effects, including: blue fingers/toes/nails, cold hands/feet, hearing changes, mental/mood changes.Sumatriptan can commonly cause chest/jaw/neck tightness, pain, or pressure that is usually not serious. However, these side effects are like symptoms of a heart attack, which may include chest/jaw/left arm pain, shortness of breath, or unusual sweating. Get medical help right away if these or other serious side effects occur, including: fast/irregular heartbeat, fainting, severe stomach/abdominal pain, bloody diarrhea, seizure, signs of a stroke (such as weakness on one side of the body, trouble speaking, sudden vision changes, confusion).This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects.
