Imigran Novum – Sumatriptan uses, dose and side effects


50 mg and 100 mg tablet

1. What Imigran Novum is and what it is used for

Imigran Novum containing sumatriptan belonging to a group of drugs called triptans ( also known as 5-HT 1 – receptor agonists).

Imigran Novum is used for treating migraines.

The migraine symptoms are probably caused by a temporary dilation of the blood vessels in the head. Imigran Novum is considered 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.

Some medicines should not be taken with Imigran Novum and others may cause side effects when used concomitantly. You must tell your doctor if you use:

Pregnancy and breastfeeding

  • If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine. There is only limited information on the safety of Imigran Novum when used in pregnant women, although there is no evidence of an increased risk of birth defects to date. Your doctor will discuss with you whether to use Imigran Novum during pregnancy.
  • You should not breast-feed your baby for the next 12 hours after using Imigran Novum. Breast milk pumped out during these 12 hours should not be given to your baby, but should be discarded.

Driving and using machines

Both the migraine symptoms and your medication can make you drowsy. If you are affected, do not drive or operate machinery. You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased vigilance. 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. Descriptions of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. If you are not sure, talk to your doctor or pharmacist.
