Imitrex Nasal Spray

How is this medication used?

Use Imitrex Nasal Spray exactly as prescribed by your doctor. The usual dose is a single spray in one nostril. Use it as soon as you notice headache symptoms, or after an attack has already begun. If your headache does not completely go away after the first dose, a second dose may be used after 2 hours. Do not use more than 40 mg of Imitrex Nasal Spray in a 24-hour period.

What are the possible side effects?

Common side effects of Imitrex Nasal Spray include unusual taste, nose irritation, nausea, vomiting, dizziness, drowsiness, weakness, and sensitivity to heat or cold. Tell your doctor if you have severe or persistent side effects, including signs of allergic reaction (rash, itching/swelling, severe dizziness, trouble breathing), signs of heart attack (chest pain, jaw/left arm pain, shortness of breath), or stroke (weakness on one side of the body, trouble speaking, sudden vision changes).

What are the potential interactions?

Imitrex Nasal Spray may interact with MAO inhibitors, antidepressants (such as SSRIs, SNRIs), other migraine headache medicines (ergotamines, triptans), and drugs that increase serotonin (such as St. John's wort, tramadol, and certain antidepressants). These interactions can cause serious side effects including serotonin syndrome. Avoid using Imitrex within 24 hours of using any ergotamine-containing or ergot-type medication, or another triptan. Always inform your doctor about all medications you're taking before starting Imitrex.
