Description

Do not take tablet if you are allergic to mefloquine or if you have a history of mental health issues like depression, anxiety, psychosis, or seizures. Common side effects include nausea, vomiting, stomach pain, dizziness, and diarrhoea. If you experience unusual mood changes or balance issues, please notify your doctor immediately.
Take tablet with or without food and swallow the tablet whole with water. Try to take it at the same time each day. Store it in a cool, dry place away from sunlight and out of children’s reach. If you miss a dose, take it as soon as you remember, unless it’s almost time for the next one. Do not double up on doses.
tablet can interact with many medications, especially those used to treat seizures, irregular heartbeats, or fungal infections. Avoid taking it with halofantrine, ketoconazole, or quinine. It may reduce the effect of certain vaccines and seizure medications. Speak to your doctor if you’re pregnant, breastfeeding, or have liver or mental health problems before starting this medicine. Avoid driving if you feel dizzy or off balance.
