How to Use Imitrex
One dose is taken by mouth at the first signs of a migraine attack. If

whole with a glass of water. Do not crush or chew them.
Imitrex Side Effects
Imitrex may initially cause flushing, dizziness, weakness, nausea, drowsiness,
stiffness, or feelings of tingling, heat, fatigue. If any of these effects
continue or become bothersome, inform your doctor. In the unlikely event
you have an allergic reaction to Imitrex, seek immediate medical attention.
Symptoms of an allergic reaction include: rash, itching, swelling, dizziness,
trouble breathing. If you notice other effects not listed above, contact
your doctor or pharmacist.
Imitrex Precautions
Tell your doctor if you have: heart disease, coronary artery disease, high
blood pressure, stroke, kidney disease, liver disease, allergies (especially
drug allergies). There have been rare reports of those with sulfa drug
allergies having allergic reactions to sumatriptan. Consult your doctor
or pharmacist. Since Imitrex may cause drowsiness, use caution operating
machinery or engaging in activities requiring alertness and avoid alcohol
because it may increase drowsiness/dizziness effects. The manufacturer
does not recommend use of sumatriptan in the elderly, because they may
be more sensitive to its side effects. Sumatriptan should be used during
pregnancy only when clearly needed. Discuss the risks and benefits with
your doctor. Imitrex is excreted into breast milk. The effects on nursing
infants are unknown at this time. Consult your doctor before breast-feeding.

within 2 weeks of stopping use of MAO inhibitors. Do not take any ergotamine-containing
medication and sumatriptan within 24 hours of each other. Also, report
