Quinine Sulphate

This medication is used to treat or prevent many types of irregular heartbeats (heart arrhythmias such as atrial fibrillation). Quinidine can greatly improve your ability to perform normal activities by decreasing the number of irregular heartbeats you have. However, it may not stop all your irregular heartbeats completely. It works by blocking abnormal heartbeat signals.

Quinine sulfate is an antimalarial drug indicated only for treatment of uncomplicated Plasmodium falciparum malaria.

Mild headache, flushing, unusual sweating, nausea, ringing in the ears, decreased hearing, dizziness, blurred vision, and temporary changes in color vision may occur. Quinine Sulphate may cause low blood sugar (hypoglycemia), especially during pregnancy.
