Mefloquine is used to prevent and treat malaria.
Take mefloquine as directed with food and a glass of water. Usually it should be swallowed whole as it has a bitter taste. It may be crushed and given in water or milk if you are unable to swallow tablets.
Take the missed dose as soon as possible. If it is close to the time for your next dose, skip the missed dose and carry on as normal. Do not take two doses at the same time.
Some medicines available without a prescription may react with mefloquine including:
Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs (e.g. ecstasy).
