About this Medication

The name of your medicine is MAXALT . It can only be obtained by prescription from your physician. The decision to use MAXALT is one that you and your physician 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 a post-menopausal female, or a male over 40), tell your physician. Your physician should evaluate you for heart disease in order to determine whether MAXALT is appropriate for you.

What the Medication is Used For

MAXALT is intended to relieve your migraine headache and other associated symptoms of a migraine attack in adults.

MAXALT should not be used continuously to prevent or reduce the number of attacks you experience. Use MAXALT only to treat an actual migraine headache attack.

What it Does

Migraine headache is believed to be caused by a widening of the blood vessels in the head. MAXALT narrows the vessels and relieves the pain and other symptoms of migraine headache.

When it should Not be Used

Do not take MAXALT if you:

  • are allergic to any of the ingredients (see What the nonmedicinal ingredients are section)
  • have uncontrolled or severe high blood pressure
  • have heart disease or history of heart disease
  • have severe liver disease
  • have had a stroke or transient ischemic attack (TIA)
  • have or have had blood vessels problems, including ischemic bowel disease
  • take monoamine oxidase (MAO) inhibitors such as moclobemide, phenelzine, tranylcypromine, or pargyline, or have taken MAO inhibitors within the last two weeks.

MAXALT should not be used to relieve pain other than that associated with migraine headache.

MAXALT should not be used within 24 hours of treatment with another 5-HT 1 agonist such as sumatriptan (Imitrex), naratriptan (Amerge) or zolmitriptan (Zomig), or ergotamine-type medications such as ergotamine, dihydroergotamine or methysergide.

Interactions with this Medication

If you are taking any other migraine medication, check with your physician first before taking MAXALT and inform your physician of any other medications you may be taking, including those obtained without a prescription.

Do not take MAXALT or MAXALT RPD if you take monoamine oxidase (MAO) inhibitors such as moclobemide, phenelzine, tranylcypromine, or pargyline, or have taken MAO inhibitors within the last two weeks.

A life-threatening condition called serotonin syndrome can happen when medicines called triptans, such as MAXALT, and medicines used to treat depression and mood disorders called SSRIs and SNRIs are used together. Signs and symptoms of serotonin syndrome include the following: restlessness, diarrhea, hallucinations, coma, loss of coordination, nausea, fast heartbeat, vomiting, increased body temperature, changes in blood pressure and overactive reflexes.

Proper Use of this Medication

REMEMBER: this medicine was prescribed only for YOU. Only a physician knows who can use it safely. Never give it to someone else. It may harm them, even if their symptoms are the same as yours.

Usual dose

For adults, the usual dosage is 5 or 10 mg, as recommended by your physician. The dose should be taken as soon as your migraine appears, but it may be taken at any time during your migraine headache.

If you are taking a tablet, swallow your dose with water.

If you are using MAXALT RPD, leave the wafer in its package until you are ready to take it. Remove the blister from the foil pouch. Do not push the wafer through the blister; rather, peel open the blister pack with dry hands and place the wafer on your tongue. The wafer will dissolve rapidly and be swallowed with your saliva. No liquid is needed to take the wafer.

A second dose may be taken if your headache returns. Repeat doses cannot be taken any sooner than 2 hours following the first dose. Do not take more than 20 mg in any 24-hour period.

For any attack where you have no response to the first dose, do not take a second dose without first consulting your physician.

Overdose

In case of drug overdose, contact a health care practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.
