For migraine:
Use one pre-filled pen at the first sign of a migraine attack (although it will be equally effective if used at
any time during an attack). If, after your first dose, your migraine goes away but then returns, you may
use another pre-filled pen, provided it is at least an hour since the first injection. DO NOT use more than

injections in 24 hours and make sure you leave at least one hour between the two doses.

1. What Sumatriptan Injection is and what it is used for
The active substance in Sumatriptan Injection is Sumatriptan. It is one of a group of medicines called 5HT1
receptor agonists.
Sumatriptan Injection is used to treat migraine headache and a rare condition called cluster headache. The
symptoms of migraine may due to temporary swelling of blood vessels in the head. Sumatriptan is
believed to work by reducing the size of these blood vessels.

2. What you need to know before you use Sumatriptan Injection

Very common( may affect more than 1 in 10 people)
- temporary pain at the place the injection was given
- stinging/burning, redness, swelling, bruising and bleeding at the place the injection was given.

As with other migraine treatments, overuse could make your migraine worse and make them occur more
You may only use Sumatriptan Injection when your doctor is certain that you suffer from migraine
headache or cluster headache.
