What does Quinine treat?

Quinine treats Malaria which is caused by a parasite that enters the red blood cells. It works by killing it and preventing growth of these parasites. Quinine is classified under the list of anti-malarials and is a highly effective drug.

Dosage Instructions

Follow the Quinine dosage prescribed by your physician. The dosage could vary based on individual patient requirements. Always follow your physician’s instructions or go by the directions on the prescription drug label. It’s to be taken along with food.

Missed a dose?

Take it immediately once you remember. In case, this time is closer to the next dosage, skip it and get back to the prescribed schedule. Never take a double dose unless your doctor specifically asks you to.


Don’t waste any time and seek immediate medical attention.

Drug Interactions

Drug interactions must be considered before starting to take any kind of drug. Drug interactions might happen either when Quinine is taken along with another drug or with particular foods. To prevent any kind of negative interaction, make sure you inform your doctor of any drugs you are taking including non-prescription medication, OTCs, health supplements like vitamins, minerals, herbal medicine and so on which may interfere with the effect of Quinine.

It may interact with:

Possible Side Effects

Quinine might have some side effects but it’s not possible to anticipate them. It does not have any major side effects and the minor ones that may occur are temporary. In rare cases, there might be major side effects and immediate medical attention must be sought.

Some of the side effects could be headache, unusual sweating, blurred vision, ringing in the ears, dizziness, nervousness, diarrhea, sweating, low blood sugar and stomach pain. Besides these, there could be other side effects too.
