ReviewShould people with nocturnal leg cramps drink tonic water and bitter lemon?
A literature search from 1993 to 1997 using MEDLINE and key-words beverages, muscle cramp, and quinine was performed. Three beverages containing quinine were examined in grocery stores. Analysis indicate that leg cramps are a common phenomenon associated with many comorbid disorders especially peripheral vascular and neurologic disorders. ⋯ It appears that 325 milligrams of quinine taken by mouth at bedtime typically relieves nocturnal leg cramps, but lower starting doses are appropriate for senior citizens and individuals with impaired renal function. In general, quinine in any form should be avoided by pregnant women and people with hepatic failure. Quinine consumed for the treatment of leg cramps should be prescribed and monitored by physicians, and people who consume quinine in commercial beverages must be warned of the health risks.
