- with other medicines to treat seizures in adults and children over age 2
- to prevent migraine headaches in adults.
2 Before you take
Do not take Topiramate tablets and tell your doctor
- if you are allergic (hypersensitive) to topiramate or any of the other ingredients of Topiramate tablets (see section 6).
- for migraine prevention do not take if you are pregnant or you are able to become pregnant but you are not using effective contraception (see ‘Pregnancy and breastfeeding’ for further information).

Especially, tell your doctor or pharmacist if you are taking:
- other medicines that impair or decrease your thinking, concentration, or muscle coordination (e.g. central nervous system depressant medicines such as muscle relaxants and sedatives).
