Concomitant administration of<unk>  with corticosteroids, diuretics, and xanthine derivatives (such as theophylline) increases the risk of hypokalemia (decreased levels of potassium in the blood).<unk>  acts as a cholinesterase inhibitor, and can prolong the duration of action of suxamethonium (succinylcholine) and other drugs whose breakdown in the body depends on cholinesterase function. Butyrylcholinesterase activity returns to normal approximately two weeks after<unk>  is stopped. It can also enhance the effects of non-depolarizing neuromuscular blockers, such as vecuronium bromide.
