Dosage Guide

Quick Answer

Sumatriptan (Imigran) is taken at the onset of a migraine headache — the standard adult starting dose is 50mg orally. If 50mg is insufficient, 100mg may be used in subsequent attacks as prescribed. A maximum of 2 doses (at least 2 hours apart) may be taken in 24 hours. Never take a second dose if the first had no effect in the same attack without doctor advice.

Dose at a Glance

Adult Dose

50mg orally at onset of headache phase (25mg or 100mg as prescribed)

As needed — only at onset of migraine headache, not for prevention

Max: Maximum 2 doses in 24 hours (second dose only if first worked and headache returned); do not exceed 300mg/24h

Child Dose (Under 18 — requires specialist guidance)

Not routinely recommended — specialist assessment required

As directed by paediatrician/neurologist only

Missed Dose

Sumatriptan is taken only when needed (acute treatment) — there is no routine scheduled dose. If sumatriptan does not work in a migraine attack, do not take a second dose in the same attack without doctor's advice.

Overdose

Sumatriptan overdose may cause chest pain, a rise in blood pressure, and cardiac problems. If an excessive dose is taken, contact a doctor or emergency services immediately.

Sumatriptan (Imigran) Dosage (Kitni leni hai)

Correct dosage and timing of Sumatriptan (Imigran) is critical for effective migraine treatment. Always follow your doctor's prescription.

Adult Dose (Baalgon ke liye)

  • At onset of migraine headache (not during aura): 50mg orally
  • If 50mg insufficient: 100mg may be prescribed for subsequent attacks
  • 25mg may be used if 50mg causes intolerable side effects
  • Maximum 2 doses in 24 hours — second dose only if first worked and headache returned (minimum 2 hours between doses)
  • Do not exceed the recommended limit

Starting Dose: 50mg at headache onset

Usual Dose: 50–100mg as prescribed

Max Daily Dose: 300mg in 24 hours (two 100mg doses + one 100mg — but always follow your doctor's specific instructions)

Child Dose (Bachon ke liye)

Sumatriptan is not routinely recommended for children under 18. Specialist paediatric neurologist assessment required before use.

A child's dose is always decided by a specialist based on weight and age. Do not calculate the dose yourself.

How to Take (Kaise leni hai)

  • Take at onset of headache phase — not during aura (less effective)
  • Swallow tablet whole with water
  • Can be taken with or without food
  • Do not crush or chew tablet

Best Time to Take (Kab leni chahiye)

  • Take as early as possible at the onset of headache — earlier use gives a better response
  • Not prophylactically — only at the time of an attack

With Food or Empty Stomach (Khali pait ya khane ke baad)

It can be taken on an empty stomach or after food. If nausea accompanies the migraine, taking it with a light snack may help.

Missed Dose (Dose chhoot jaye to kya karein)

Sumatriptan is an as-needed (PRN) medicine — no scheduled dose. If the first dose has no effect in an attack, do not take a second dose in the same attack on your own.

Overdose (Zyada Dose)

Sumatriptan overdose may cause chest pain, a rise in blood pressure, and cardiac/neurological problems. If an excessive dose has been taken, contact a doctor or the nearest emergency room immediately.

Frequently Asked Questions

Sumatriptan ki standard adult dose kya hai?

The standard starting dose is a 50mg oral tablet at the onset of migraine headache. If 50mg is insufficient, 100mg may be tried in subsequent attacks on doctor's advice. Maximum 2 doses in 24 hours.

Kya sumatriptan khali pait li ja sakti hai?

Yes, sumatriptan can be taken on an empty stomach or after food. Nausea is common with migraine — taking it with a little water may help.

Agar sumatriptan se pehle attack mein koi fayda nahi hua to kya karein?

Do not take a second dose in the same attack if the first had no effect. The dose may be increased (50 to 100mg) in subsequent attacks but consult a doctor first. If there is no benefit in 3 attacks, have the diagnosis reviewed.

Sumatriptan kitni baar mahine mein le sakte hain?

Using it on more than 10 days per month carries a risk of medication-overuse headache (MOH/rebound headache). If migraines are that frequent, discuss prophylactic treatment with a doctor.

Sumatriptan aur ergotamine ek saath le sakte hain?

No — sumatriptan must not be taken together with ergotamine or dihydroergotamine, or within 6 hours of either. Combined use causes vasoconstriction severe enough to create a serious circulatory problem.
