Interactions
May reduce effects of anticholinergics. May increase effects of cholinergic agonists. Increased risk of bradycardia with digoxin, diltiazem, verapamil or beta-blockers without intrinsic sympathomimetic activity. Increased muscle weakness and decreased response to anticholinesterases with corticosteroids. May increase effects of depolarising neuromuscular blockers. Effects may be antagonised by drugs with neuromuscular blocking activity e.g. aminoglycosides, clindamycin, colistin, cyclopropane, halogenated inhalational anaesthetics. Effects may be reduced by quinine, chloroquine, hydroxychloroquine, quinidine, procainamide, propafenone, lithium, beta-blockers. Possible additive toxicity with ophthalmic use of anticholinesterases e.g. ecothiopate.
