Descriptions


Almotriptan is used to treat acute migraine headaches in adults and teenagers. It is not used to prevent migraine headaches and is not used for cluster headaches. Almotriptan works in the brain to relieve the pain from migraine headaches. It belongs to the group of medicines called triptans.

Almotriptan is not an ordinary pain reliever. It will not help with any kind of pain other than migraine headaches. This medicine is usually used in people whose headaches are not helped or relieved by acetaminophen (Tylenol®), aspirin, or other pain relievers.

This medicine is available only with your doctor's prescription.

This product is available in the following dosage forms:

  • Tablet

Before Using

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of almotriptan in children younger than 12 years of age. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of almotriptan in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving almotriptan.

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Precautions

It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it.

Check with your doctor if you used this medicine and your migraine did not go away, or if your migraine got worse or started occurring more often.

You should not take this medicine if you have used other triptan or ergot-type migraine medicines within the past 24 hours. Some examples of triptan medicines are frovatriptan (Frova®), naratriptan (Amerge®), rizatriptan (Maxalt®), sumatriptan (Imitrex®, Treximet®), and zolmitriptan (Zomig®). Some examples of ergot-type medicines are dihydroergotamine (D.H.E. 45®, Migranal®), ergotamine (Bellergal®, Cafergot®, Ergomar®, or Wigraine®), and methysergide (Sansert®).

This medicine may cause problems if you have heart disease. If your doctor thinks you might have a problem with this medicine, he or she may want you to take your first dose in the doctor’s office or clinic.

This medicine may increase your risk of having a heart attack, angina, or stroke. This is more likely to occur if you or a family member already have heart disease, if you smoke, if you are male and over 40 years of age, or if you are female and have gone through menopause. Call your doctor right away if you have any symptoms of a heart problem, such as chest pain or discomfort, an irregular heartbeat, nausea or vomiting, pain or discomfort in the shoulders, arms, jaw, back, or neck, shortness of breath, or sweating. Call your doctor right away if you have any symptoms of a stroke, such as confusion, difficulty with speaking, double vision, headaches, an inability to move the arms, legs, or facial muscles, an inability to speak, or slow speech.

Check with your doctor right away if you have chest discomfort, jaw or neck tightness after taking this medicine. Also, tell your doctor if you have sudden or severe abdominal or stomach pain or bloody diarrhea after using this medicine.

Make sure your doctor knows about all the other medicines you are using. Almotriptan may cause a serious condition called serotonin syndrome when taken with some medicines. This includes medicines to treat depression, such as citalopram (Celexa®), duloxetine (Cymbalta®), escitalopram (Lexapro®), fluoxetine (Prozac®, Sarafem®, or Symbyax®), fluvoxamine (Luvox®), paroxetine (Paxil®), sertraline (Zoloft®), or venlafaxine (Effexor®). Check with your doctor right away if you have agitation, confusion, diarrhea, excitement while talking that is not normal, fever, overactive reflexes, poor coordination, restlessness, shivering, sweating, trembling or shaking that you cannot control, or twitching. These could be symptoms of serotonin syndrome.

Using almotriptan alone or in combination with other migraine medicines for 10 or more days per month may lead to worsening of headache. You may keep a headache diary to record your headache frequency and drug use.

Check with your doctor right away if you have blurred vision, difficulty with reading, or any other change in vision while you are using this medicine. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).

Almotriptan may cause drowsiness, dizziness, or trouble with your vision. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that requires you to be alert and able to see well.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
