Although quinine is no longer the primary treatment for malaria, its use has been effective for other ailments. In the United States, quinine is prescribed for nighttime leg cramps and arthritis. However, due the hazards of the drug, the Food and Drug Administration banned over-the-counter quinine in 1994. While quinine is still available with a prescription in the United States, the FDA does not fully support it as an option for leg cramp relief. In regards the malaria, the FDA feels quinine use is valid, since it is a life-threatening illness.
