What you will receive

Imitrex is the originator brand name, made by GSK. We use it here to identify the medicine only; we are not affiliated with GSK and do not ship the original Imitrex.

  • You receive a generic equivalent: the same active ingredient (Sumatriptan) at the same dose, mostly recognised Indian branded generics from vetted manufacturers.
  • The exact brand supplied depends on what is in stock at the dispatching warehouse.
  • Inactive ingredients, tablet appearance and packaging can differ from the original brand; the active ingredient and dose are the same.
