Who is this for?

Quinine Sulfate is an antimalarial drug that works by killing the malaria parasites living inside your red blood cells, stopping them from multiplying and clearing the infection from your body.

Is Quinine safe to take with another drug?

For adults treating malaria, the usual dose is 600 mg (two 300 mg tablets) taken every 8 hours — that means 3 times a day — for 7 days. Take the tablets with food or a glass of water to reduce stomach upset. The tablets can taste very bitter, so swallow them whole without chewing. You may be told to combine quinine with another antimalarial like doxycycline or clindamycin to make sure the malaria is fully cleared.

If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue as normal. Do not take two doses at once to make up for it.

• Ringing or buzzing sound in the ears (called cinchonism)
• headache
• nausea or vomiting
• blurred vision
• dizziness. These symptoms often go away as your body adjusts
• but tell your doctor if they are severe.

Do not take quinine with mefloquine (another antimalarial) as it increases the risk of seizures and heart problems. Quinine can increase the effect of blood-thinning drugs like warfarin, causing dangerous bleeding. Avoid alcohol while taking quinine as it can worsen dizziness and stomach upset.

Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can be hot, so avoid storing near windows or in cars. Keep the tablets in their original container and always keep out of reach of children.
