10Quinine
Quinine has been used for treating muscle cramps since the 40s when there have been no other reliable options developed. The only brand name that contains quinine is Qualaquin, which is allowed by the Food and Drug Administration. While it can be an effective option, there are some side effects to consider such as kidney failure, eye issues, hearing problems, allergic reactions, and rashes, or cardiac problems. Thus, make sure to consult your doctor about all of the available treatment choices before choosing quinine. [10]
