Sumatriptan Sandoz – Sumatriptan uses, dose and side effects


50 mg film-coated tablets

What Sumatriptan Sandoz is and what it is used for

Each Sumatriptan Sandoz tablet contains a single dose of sumatriptan, which belongs to a group of medicines called triptans (also called 5-HT 1 – receptor agonists ).

Sumatriptan Sandoz is a medicine used in the treatment of acute migraine , with or without aura (a sensation that usually consists of visual disturbances such as flashes, zigzag lines, stars or waves). Sumatriptan Sandoz should only be used when you have signs or symptoms of a migraine attack. Migraine headaches are usually of moderate to severe intensity , unilateral (but can switch sides between attacks) and have a pulsating character. Symptoms such as nausea, sometimes vomiting, and significant sensitivity to light and sound are common in migraines .

The migraine symptoms are probably caused by a temporary dilation of the blood vessels in the head. Sumatriptan Sandoz is thought to reduce the dilation of these blood vessels. This contributes to the disappearance of the headache as well as other migraine symptoms such as nausea, vomiting and sensitivity to light and sound.

Sumatriptan Sandoz is not intended for the treatment of other types of headache, such as tension headache.

What you need to know before using Sumatriptan Sandoz

Sumatriptan Sandoz should only be used by you who know you have migraines .

  • has a pulsating character and is one-sided
  • has moderate to strong intensity and lasts for 4-72 hours
  • worsens with normal physical activity (eg walking or climbing stairs)
  • affects your ability to concentrate and your daily tasks

Migraine can be accompanied by other symptoms such as:

  • Nausea, sensitivity to light and sound
  • Aura symptoms, for example visual field loss, zigzag patterns or flashes in the visual field , and less often numbness or speech difficulties.

Some medicines should not be taken together with Sumatriptan Sandoz and others can cause side effects when used at the same time.

You must tell your doctor if you use:

  • Ergotamine which is also used to treat migraines or similar medications such as methysergide. Do not use Sumatriptan Sandoz at the same time as these medicines. You must stop taking these at least 24 hours before using Sumatriptan Sandoz. Do not take any medicine containing ergotamine or substances similar to ergotamine until at least 6 hours after taking Sumatriptan Sandoz.

Driving ability and use of machinery

Both the migraine symptoms and your medication can make you drowsy. If you are affected, you should not drive or operate machinery.

You yourself are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects . Description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with your doctor or pharmacist if you are unsure.
