This medication is used alone or with other medication to treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. This medication is used to kill the malaria parasites living inside red blood cells. In some cases, you may need to take a different medication (such as primaquine) to kill the malaria parasites living in other body tissues. Both drugs may be needed for a complete cure and to prevent the return of infection (relapse). Quinine belongs to a class of drugs known as antimalarials. It is not used for the prevention of malaria.The United States Centers for Disease Control provide updated guidelines and travel recommendations for the prevention and treatment of malaria in different parts of the world. Discuss the most recent information with your doctor before traveling to areas where malaria occurs.
Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking quinine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
