From the Guidelines
The recommended dose of Imitrex (sumatriptan) for as-needed migraine treatment is 25 to 100 mg taken orally every two hours, with a maximal dosage of 200 mg per day. According to the study published in the American Family Physician 1, this dosage is effective in treating moderate to severe migraines. The study also notes that Imitrex can be administered subcutaneously (6 mg, repeated in one hour, with a maximal dosage of 12 mg per 24 hours) or intranasally (5 to 10 mg, one to two sprays, in one nostril, with a dose that may be repeated after 2 hours to a maximal dosage of 40 mg per day). It's essential to start with a lower dose, such as 25 mg, if you're new to the medication or concerned about side effects. Common side effects of Imitrex include nausea, warmth, vomiting, vertigo, malaise, headache, injection site reactions, and chest pressure and heaviness. Imitrex works by constricting blood vessels and blocking pain pathways in the brain, and it should not be taken with other triptans, ergotamines, or MAOIs. People with heart disease, uncontrolled hypertension, or stroke history should avoid taking Imitrex due to the risk of adverse reactions.
Some key points to consider when taking Imitrex for migraines include:
- Taking the medication as soon as you recognize migraine symptoms for best results
- Not exceeding the maximal dosage of 200 mg per day
- Avoiding chronic use due to the potential for peripheral vasoconstriction
- Consulting the current Physician's Desk Reference and other pharmacologic resources before prescribing or taking Imitrex, as the information provided is not all-inclusive in treatment protocols, contraindications, or adverse reactions 1.
It's crucial to weigh the benefits and risks of Imitrex and consider individual patient needs and medical history when determining the best course of treatment for migraines.
