Information About Your Medicine

The name of your medicine is AMERGE (naratriptan hydrochloride) Tablets. It can be obtained only by prescription from your doctor. The decision to use AMERGE (naratriptan) Tablets is one that you and your doctor should make jointly, taking into account your individual preferences and medical circumstances. If you have risk factors for heart disease (such as high blood pressure, high cholesterol, obesity, diabetes, smoking, strong family history of heart disease, or you are postmenopausal or a male over 40), you should tell your doctor, who should evaluate you for heart disease in order to determine if AMERGE (naratriptan) is appropriate for you. The majority of those who have taken AMERGE (naratriptan) Tablets have not experienced any significant side effects. Rarely, deaths and/or serious heart problems have been reported with this class of medicines; in all but a few instances, however, these deaths and/or serious heart problems occurred in people with heart disease and it was not clear whether these medicines were a contributing factor.

1. The Purpose of Your Medicine:

AMERGE (naratriptan) Tablets are intended to relieve your migraine, but not to prevent or reduce the number of attacks you experience. Use AMERGE (naratriptan) Tablets only to treat an actual migraine attack.

2. Important Questions to Consider Before Taking AMERGE (naratriptan) Tablets:

If the answer to any of the following questions is YES or if you do not know the answer, then please discuss it with your doctor before you use AMERGE (naratriptan) Tablets.

  • Are you pregnant? Do you think you might be pregnant? Are you trying to become pregnant? Are you not using adequate contraception? Are you breastfeeding?
  • Do you have any chest pain, heart disease, shortness of breath, or irregular heartbeats? Have you had a heart attack?
  • Do you have risk factors for heart disease (such as high blood pressure, high cholesterol, obesity, diabetes, smoking, strong family history of heart disease, or you are postmenopausal or a male over 40)?
  • Have you had a stroke, transient ischemic attacks (TIAs), or Raynaud syndrome?
  • Do you have high blood pressure?
  • Have you ever had to stop taking this or any other medicine because of an allergy or other problems?
  • Are you taking any other migraine medicines, including other 5-HT1 agonists such as IMITREX®* (sumatriptan/sumatriptan succinate), or medicines containing ergotamine, dihydroergotamine, or methysergide?
  • Are you taking any medicine for depression or other disorders such as selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs)? Common SSRIs are citalopram HBr (CELEXA® ), escitalopram oxalate (LEXAPRO® ), paroxetine (PAXIL® ), fluoxetine (PROZAC® /SARAFEM® ), olanzapine/fluoxetine (SYMBYAX® ), sertraline (ZOLOFT® ), and fluvoxamine. Common SNRIs are duloxetine (CYMBALTA® ) and venlafaxine (EFFEXOR® ).*
  • Have you had, or do you have, any disease of the kidney or liver?
  • Is this headache different from your usual migraine attacks?

Remember, if you answered YES to any of the above questions, then discuss it with your doctor.

3. The Use of AMERGE (naratriptan) Tablets During Pregnancy:

Do not use AMERGE (naratriptan) Tablets if you are pregnant, think you might be pregnant, are trying to become pregnant, or are not using adequate contraception, unless you have discussed this with your doctor.

4. How to Use AMERGE (naratriptan) Tablets:

For adults, the usual dose is a single tablet taken whole with fluids. It may be given at any time after the headache starts. For an individual attack, if you have no response to the first tablet, do not take a second tablet without first talking to your doctor. If you need more relief due to a partial response or return of your headache after the first tablet, a second tablet may be taken, but not sooner than 4 hours following the first tablet. Do not take more than a total of 2 AMERGE (naratriptan) Tablets in any 24-hour period. If you have kidney or liver disease, take as directed by your doctor.

5. Side Effects to Watch for:

  • Some patients experience pain or tightness in the chest or throat when using AMERGE (naratriptan) Tablets. If this happens to you, then discuss it with your doctor before using any more AMERGE (naratriptan) Tablets. If the chest pain, tightness, or pressure is severe or does not go away, call your doctor immediately.
  • If you have sudden and/or severe abdominal pain following AMERGE (naratriptan) Tablets, call your doctor immediately.
  • Some people may have a reaction called serotonin syndrome when they use certain types of antidepressants, SSRIs or SNRIs, while taking AMERGE (naratriptan) Tablets. Symptoms may include confusion, hallucinations, fast heart beat, feeling faint, fever, sweating, muscle spasm, difficulty walking, and/or diarrhea. Call your doctor immediately if you have any of these symptoms after taking AMERGE (naratriptan) Tablets.
  • Shortness of breath; wheeziness; heart throbbing, swelling of eyelids, face, or lips; or a skin rash, skin lumps, or hives happens rarely. If it happens to you, then tell your doctor immediately. Do not take any more AMERGE (naratriptan) Tablets unless your doctor tells you to do so.
  • Some people may have feelings of tingling, heat, flushing (redness of face lasting a short time), heaviness or pressure after treatment with AMERGE (naratriptan) Tablets. A few people may feel drowsy, dizzy, tired, or sick. Tell your doctor of these symptoms at your next visit.

If you have taken more medicine than you have been told, contact either your doctor, hospital emergency department, or nearest poison control center immediately.
