It is very important that your doctor check the progress of you or your child at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you or your child should continue to take it.
You should not take this medicine if you or your child have used other triptan or ergot-type migraine medicines within the past 24 hours. Some examples of triptan medicines are almotriptan (Axert™), eletriptan (Relpax®), frovatriptan (Frova®), naratriptan (Amerge®), 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®). Do not take this medicine within 2 weeks after taking an MAO inhibitor, such as Eldepryl®, Marplan®, Nardil®, or Parnate®.
Check with your doctor if you or your child used this medicine and your migraine did not go away, or if your migraine got worse or started occurring more often.
This medicine may increase your risk of having abnormal heart rhythm, heart attack, angina, or stroke. This is more likely to occur if you or a family member already has heart disease, if you have diabetes, high blood pressure, high cholesterol, 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 uneven 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 or your child 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.
Check with your doctor right away if you have blurred vision, difficulty with reading, or any other change in vision while you or your child are using this medicine. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).
Using rizatriptan 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 the headache frequency and drug use.
Make sure your doctor knows about all the other medicines you are using. Rizatriptan 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®), olanzapine (Zyprexa®), paroxetine (Paxil®), sertraline (Zoloft®), or venlafaxine (Effexor®). Check with your doctor right away if you or your child 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.
Drinking alcoholic beverages can make headaches worse or cause new headaches to occur. People who suffer from severe headaches should probably avoid alcoholic beverages, especially during a headache.
Some people feel dizzy or drowsy during or after a migraine, or after taking rizatriptan to relieve a migraine. As long as you are feeling dizzy or drowsy, do not drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.
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.
