Answer :

The correct dosing for sumatriptan in the treatment of migraines is option 3: 50-100 mg initially and dosage may be repeated after 2 hours, with a maximum dosage of 200 mg/day.

Explanation:

Sumatriptan is a medication commonly used to treat migraine headaches. It belongs to the class of medications known as triptans, which work by narrowing blood vessels around the brain and reducing substances in the body that can trigger headache pain, nausea, and sensitivity to light and sound.

Dosage Details:

  • Initial dose: Patients are typically advised to take 50 to 100 mg of sumatriptan orally at the onset of a migraine attack.
  • Repeat dosing: If symptoms are not sufficiently relieved, it is safe to take another dose after at least 2 hours.
  • Maximum dose: The maximum recommended dose is 200 mg in a 24-hour period.

Important Considerations:

  • Who Can Take Sumatriptan? Oftentimes, individuals with known cardiovascular conditions should not use sumatriptan without consulting their healthcare provider due to potential risks associated with narrowing of blood vessels.
  • When to Take Sumatriptan? It is most effective if taken at the first sign of a migraine. It is not intended for preventative use or to decrease the number of attacks.
  • Side Effects and Interactions: Patients should be aware of potential side effects, such as dizziness and drowsiness, and discuss with their healthcare provider any other medications they are taking to avoid interactions.

This dosing guideline helps ensure that patients use the medication safely and effectively while minimizing potential side effects.
