Fine tremor of skeletal muscle, palpitations, muscle cramps, tachycardia, nervous tension, headache, peripheral vasodilatation, hypersensitivity reactions.
Potentially Fatal: Large doses may result in severe hypokalaemia.

Increased risk of hypokalaemia when used with potassium-depleting drugs eg. corticosteroids, diuretics and theophylline. May enhance neuromuscular blockade produced by pancuronium and vecuronium. Increased risk of digitalis-induced arrhythmias.
