Malaria is a serious infection, and if not treated, can be life-threatening. Quinine Sulfate has been used for many years as an effective treatment for uncomplicated malaria caused by the parasite Plasmodium falciparum.

What is Qualaquin?

Qualaquin is a prescription medication used in the treatment of uncomplicated malaria caused by the parasite Plasmodium falciparum.

Qualaquin is NOT approved for the prevention of malaria or for the prevention or treatment of nighttime leg cramps.

Who should not take Qualaquin?

Do not take Qualaquin if you:

  • Had previous allergic reactions to quinine, quinidine, or mefloquine (Lariam®).

  • Have myasthenia gravis.
  • Have optic neuritis, which is an inflammation of the nerve important for vision.

Tell your doctor or health care provider:

  • About all your medical conditions, including any heart, kidney, or liver problems.
  • About all the prescription and non-prescription medications you are taking, including vitamins and herbal medications.
  • If you are pregnant or could be pregnant. Treatment of malaria is important because it can be a serious disease for a pregnant woman and her unborn baby. Your doctor can tell you more about the benefits and risks of taking this medication during pregnancy for uncomplicated malaria. You and your doctor can decide if Qualaquin is right for you.
  • If you are breast-feeding. Small amounts of Qualaquin can pass into the breast milk, but no problems with this medicine have been reported in nursing babies. Discuss with your doctor whether you should breastfeed while taking Qualaquin.

  • Unless directed otherwise by your doctor, the usual dose is 648 mg (two 324 mg capsules) of Qualaquin every 8 hours by mouth at the same time every day for 7 days.
  • To lower the chance of stomach upset, take this medication WITH FOOD.
  • Finish all the Qualaquin that is prescribed even if you feel better. Do not stop taking the medication without talking to your doctor.
  • Do not take more than the amount prescribed. Do not take more than 2 capsules at one time or more than 3 doses in one day. If you take more than the prescribed dose, call your doctor right away.

What should I do if I miss a dose?
