Dosage and Administration

IMIGRAN should not be used prophylactically. The recommended dose of IMIGRAN should not be exceeded.

It is advisable that sumatriptan be given as early as possible after the onset of a migraine headache. It is equally effective at whatever stage of the attack it is administered.

Populations

• Adults

  The recommended dose of oral IMIGRAN is a single 50 mg tablet. Some patients may require 100 mg.

  If a patient does not respond to the first dose of IMIGRAN, a second dose should not be taken for the same attack. IMIGRAN tablets may be taken for subsequent attacks.

  If the patient has responded to the first dose, but the symptoms recur a second dose may be given, provided that there is a minimum interval of two hours between doses and not more than 300 mg is taken in any 24-hour period.

  The tablets should be swallowed whole with water.

• Children and Adolescents (under 18 years of age)

  The safety and efficacy of sumatriptan tablets in this population has not been demonstrated.

• Elderly (over 65 years of age)

  Experience of the use of sumatriptan tablets in patients aged over 65 years is limited. The pharmacokinetics do not differ significantly from a younger population, but until further clinical data are available, the use of IMIGRAN in patients aged over 65 years is not recommended.
