Practical information on using quinine

Quinine is used orally to treat uncomplicated malaria and intravenously to treat severe malaria.

Hypersensitivity or drug accumulation may lead to cinchonism (tinnitus, impaired hearing, headache, gastrointestinal disturbances, visual disturbances). Other adverse effects include urticaria, fever, rash, dyspnoea, and, in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency, haemolytic anaemia.
