Sumatriptan: Dosage, Side Effects and How It Works
Sumatriptan stops migraines by narrowing blood vessels around the brain. Costs typically run 10 to 50 dollars per dose without insurance. Works best when taken early.
How Sumatriptan Works
Sumatriptan is a triptan class migraine abortive. It works by narrowing blood vessels around the brain and reducing substances in the body that can trigger headaches, nausea, sensitivity to light and sound, and other migraine symptoms.
Dosage and Forms
Sumatriptan comes as a tablet, nasal spray, or injection. Standard tablet dosing starts at 25 mg to 100 mg, taken as soon as migraine symptoms appear. A second dose can be taken two hours later if the first dose does not fully relieve symptoms, up to 200 mg per day maximum.
Cost Without Insurance
Out-of-pocket sumatriptan typically costs 10 to 50 dollars per dose, depending on the form and where you fill it. Lead with generic versions cost significantly less than brand-name Imitrex.
Side Effects
Common side effects include dizziness, tingling, flushing and chest tightness. Most side effects are mild and temporary. Serious side effects are rare but can include changes in heart rhythm or severe allergic reactions.
When to Take It
Sumatriptan works best when taken at the first sign of migraine pain, before symptoms worsen. Starting early increases the chances of complete relief and reduces the dose needed.
