Postmarketing Experience
Hypersensitivity reactions (including angioedema, anaphylactic reactions and eye disorders including visual impairment, vision blurred) reported
Warnings
Contraindications
Hypersensitivity, severe hepatic or renal impairment, migraine prophylaxis
Ischemic heart disease, coronary artery vasospasm, including Prinzmetal's variant angina, uncontrolled HTN, hemiplegic or basilar migraines, cluster HA, cerebrovascular syndromes, PVD
Do not use within 24 hr of another 5-HT1 agonist or ergot derivative, or within 2 weeks of MAOIs
Ergotamine-containing and ergot-type medications
Concomitant Use With 5-HT1 Agonists (eg, Triptans)
Cautions
Transient and permanent blindness and partial vision loss have been reported with 5-HT-1 agonists
Use caution when prescribing to patient with known hypersensitivity to sulfonamides due to sulfonyl group in chemical structure of drug; sulfonyl group is structurally different from a sulfonamide; cross-sensitivity to almotriptan not systematically evaluated
Administer with caution to patients with diseases that may alter absorption, metabolism, or excretion of drugs, such as those with impaired hepatic or renal function
Adverse cardiac events
- Serious adverse cardiac events, including acute myocardial infarction, reported within a few hours following administration of the drug; life-threatening disturbances of cardiac rhythm and death have been reported within a few hours following administration of other triptans; considering the extent of use of triptans in patients with migraine, the incidence of these events is extremely low
- May cause coronary vasospasm, patients who experience signs or symptoms suggestive of angina following dosing should be evaluated for presence of coronary artery disease (CAD) or a predisposition to Prinzmetal’s variant angina before receiving additional doses of medication, and should be monitored electrocardiographically if dosing is resumed and similar symptoms recur
- Because of potential of this class of compound (5-HT1 agonists) to cause coronary vasospasm, drug should not be given to patients with documented ischemic or vasospastic coronary artery disease
- It is strongly recommended that drug not be given to patients in whom unrecognized CAD is predicted by presence of risk factors (eg, hypertension, hypercholesterolemia, smoker, obesity, diabetes, strong family history of CAD, female with surgical or physiological menopause, or male over 40 years of age) unless a cardiovascular evaluation provides satisfactory clinical evidence that the patient is reasonably free of coronary artery and ischemic myocardial disease or other significant underlying cardiovascular disease
- The sensitivity of cardiac diagnostic procedures to detect cardiovascular disease or predisposition to coronary artery vasospasm is modest, at best; if, during the cardiovascular evaluation, the patient’s medical history, electrocardiographic or other investigations reveal findings indicative of, or consistent with, coronary artery vasospasm or myocardial ischemia, the drug should not be administered
- For patients with risk factors predictive of CAD, who are determined to have a satisfactory cardiovascular evaluation, it is strongly recommended that administration of first dose of therapy take place in the setting of a physician’s office or similar medically staffed and equipped facility unless patient has previously received the drug
- Because cardiac ischemia can occur in the absence of clinical symptoms, consideration should be given to obtaining on first occasion of use an ECG during interval immediately following the dose, in these patients with risk factors
- It is recommended that patients who are intermittent long-term users and who have or acquire risk factors predictive of CAD, as described above, undergo periodic interval cardiovascular evaluation as they continue to use the drug
- The systematic approach described above is intended to reduce likelihood that patients with unrecognized cardiovascular disease will be inadvertently exposed to the drug
- The ability of cardiac diagnostic procedures to detect all cardiovascular diseases or predisposition to coronary artery vasospasm is modest at best
- Cardiovascular events associated with triptan treatment have occurred in patients with no cardiac history and with documented absence of coronary artery disease
Sensations of pain, tightness, pressure of the chest and/or throat neck, and jaw
- Sensations of tightness, pain, pressure, and heaviness in precordium, throat, neck, and jaw reported after treatment; because 5- HT1 agonists may cause coronary vasospasm
- Patients who experience signs or symptoms suggestive of angina following dosing should be evaluated for presence of CAD or a predisposition to Prinzmetal’s variant angina before receiving additional doses of medication, and should be monitored electrocardiographically if dosing is resumed and similar symptoms occur
- Patients shown to have CAD and those with Prinzmetal’s variant angina should not receive 5-HT1 agonists
Cerebrovascular events and fatalities
- Cerebral hemorrhage, subarachnoid hemorrhage, stroke, and other cerebrovascular events reported in patients treated with other triptans and some resulted in fatalities
- In a number of cases, it appeared possible that the cerebrovascular events were primary, the triptan having been administered in the incorrect belief that the symptoms experienced were a consequence of migraine, when they were not
- As with other acute migraine therapies, before treating headaches in patients not previously diagnosed as migraineurs and in migraineurs who present with atypical symptoms, care should be taken to exclude other potentially serious neurological conditions
- It should be noted that patients with migraine may be at increased risk of certain cerebrovascular events (eg, stroke, hemorrhage, and transient ischemic attack)
Vasospasm-related events, including peripheral vascular ischemia and Colonic Ischemia
- Therapy may cause vasospastic reactions other than coronary artery vasospasm, such as peripheral and gastrointestinal vascular ischemia with abdominal pain and bloody diarrhea
- Very rare reports of transient and permanent blindness and significant partial vision loss reported with use of triptans; visual disorders may also be part of a migraine attack
- Patients who experience symptoms or signs suggestive of decreased arterial flow following use of any triptan, such as ischemic bowel syndrome or Raynaud’s syndrome, are candidates for further evaluation
Serotonin syndrome
- The development of a potentially life-threatening serotonin syndrome may occur with triptans, including the drug, particularly during combined use with selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs)
- If concomitant treatment with the drug and an SSRI (eg, fluoxetine, paroxetine, sertraline, fluvoxamine, citalopram, escitalopram) or SNRI (eg, venlafaxine, duloxetine) is clinically warranted, careful observation of the patient is advised, particularly during treatment initiation and dose increases
- Serotonin syndrome symptoms may include mental status changes (eg, agitation, hallucinations, coma), autonomic instability (eg, tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (eg, hyperreflexia, incoordination) and/or gastrointestinal symptoms (eg, nausea, vomiting, diarrhea)
Medication overuse headache
- Overuse of acute migraine drugs (eg, ergotamine, triptans, opioids, or combination of these drugs for 10 or more days per month) may lead to exacerbation of headache (medication overuse headache)
- Medication overuse headache may present as migraine-like daily headaches or as a marked increase in frequency of migraine attacks
- Detoxification of patients, including withdrawal of overused drugs, and treatment of withdrawal symptoms (which often includes a transient worsening of headache) may be necessary
Increases in blood pressure
- As with other triptans, significant elevations in systemic blood pressure have been reported on rare occasions in patients with and without a history of hypertension; very rarely these increases in blood pressure have been associated with significant clinical events
- Therapy is contraindicated in patients with uncontrolled hypertension In normotensive healthy subjects and patients with hypertension controlled by medication

ALMOTRIPTAN - ORAL
(AL-moe-TRIP-tan)
COMMON BRAND NAME(S): Axert
USES: Almotriptan 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. Almotriptan belongs to a class of drugs known as triptans. It affects a certain natural substance (serotonin) that narrows blood vessels in the brain. It may also relieve pain by affecting certain nerves in the brain.Almotriptan does not prevent future migraines or lessen how often you get migraine attacks.
HOW TO USE: Read the Patient Information Leaflet if available from your pharmacist before you start taking almotriptan and each time you get a refill. If you have any questions, ask your doctor or pharmacist.If you have a higher risk for heart problems (see Precautions), your doctor may perform a heart exam before you start taking almotriptan. He/she may also direct you to use 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.Take this medication by mouth with or without food as directed by your doctor at the first sign of a migraine. Do not take almotriptan to prevent a migraine.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 take a second dose after 2 hours. Do not take more than 2 doses in a 24-hour period.The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).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: Drowsiness, dizziness, nausea, sensations of tingling/numbness/prickling, or dry mouth may occur. If any of these effects last or get worse, 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.Tell your doctor right away if you have any serious side effects, including: blue fingers/toes/nails, cold sensation of hands/feet, hearing changes, mental/mood changes.This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.Almotriptan 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, 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. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: See also How to Use section.Before taking almotriptan, tell your doctor or pharmacist if you are allergic to it; or to other triptan migraine drugs; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: blood circulation problems (for example, in your legs, arms/hands, or stomach), certain types of headaches (hemiplegic or basilar migraine), heart problems (such as chest pain, irregular heartbeat, previous heart attack), stroke or "mini-stroke" (transient ischemic attack), kidney disease, liver disease.Certain conditions can increase your risk for heart problems. Tell your doctor if you have any of these conditions, including: diabetes, family history of heart disease, high blood pressure, high cholesterol, overweight, smoker, postmenopausal (women), age more than 40 years (men).This drug may make you dizzy or drowsy. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).The risk of heart disease, liver disease, and high blood pressure increases with age. Older adults may be more sensitive to the side effects of this drug, especially increased blood pressure and heart problems.During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.It is unknown if this medication passes into breast milk. Consult your doctor before breast-feeding.
DRUG INTERACTIONS: Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (including SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.If you also take any ergotamine medication (such as dihydroergotamine) or other "triptan" drugs (such as zolmitriptan, rizatriptan), you will need to separate your almotriptan dose from your dose of these other medications to lessen the chance of serious side effects. Ask your doctor how long you should wait between your doses of these drugs.
OVERDOSE: If someone has overdosed and has serious symptoms such as passing out or trouble breathing, call 911. Otherwise, call a poison control center right away. US residents can call their local poison control center at 1-800-222-1222. Canada residents can call a provincial poison control center.
NOTES: Do not share this medication with others.Certain foods, beverages, or food additives (such as red wine, cheese, chocolate, monosodium glutamate) as well as lifestyle patterns such as irregular eating/sleeping habits or stress may bring on a migraine headache. Avoiding such "triggers" may help lessen migraine attacks. Consult your doctor for more details.Lab and/or medical tests (such as blood pressure) may be done while you are using this medication. Keep all medical and lab appointments.
MISSED DOSE: Not applicable. (See How to Use section.)
