Description
Quinine sulfate at a dose of 200–300 mg at night has been used for many years to treat nocturnal leg cramps. Usually idiopathic, these muscle cramps are common, particularly in older patients. Quinine may help by decreasing the excitability of the motor end-plate and increasing the muscle refractory period.
SIDE EFFECTS
headache, blurred vision, changes in color vision; · sweating or flushing (warmth, redness, or tingly feeling).
