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.

Allergic: Allergic reactions and anaphylaxis
Neurologic: Dizziness, convulsions, loss of consciousness, drowsiness, headache, dysarthria, miosis and visual changes
Cardiovascular: Cardiac arrhythmias (including bradycardia, tachycardia, A-V block and nodal rhythm) and nonspecific EKG changes have been reported, as well as cardiac arrest, syncope and hypotension (predominantly with parenteral dosage form)
Respiratory: Increased oral, pharyngeal and bronchial secretions, and dyspnea; respiratory depression, respiratory arrest and bronchospasm have been reported following the use of the injectable form
Dermatologic: Rash and urticaria
Gastrointestinal: Nausea, emesis, flatulence, and increased peristalsis and salivation
Genitourinary: Urinary frequency
Musculoskeletal: Muscle cramps and spasms, arthralgia
Miscellaneous: Diaphoresis, flushing and weaknes
Potentially Fatal: Anaphylaxis.
Mechanism of Action
Neostigmine reversibly inhibits acetylcholinesterase and thus potentiates the nicotinic and muscarinic effects of acetylcholine. This facilitates the transmission of impulses across myoneural junction.
