WARNINGS Prostigmin should be used with caution in patients with epilepsy, bronchial asthma, bradycardia, recent coronary occlusion, vagotonia, hyperthyroidism, cardiac arrhythmias or peptic ulcer. As a rule, 15 mg of neostigmine bromide orally is equivalent to 0.5 mg of neostigmine methylsulfate parenterally, due to poor absorption of the tablet from the intestinal tract. Large doses should be avoided in situations where there might be an increased absorption rate from the intestinal tract. It should be used with caution when co-administered with anticholinergic drugs, in order to avoid reduction in intestinal mobility.
ADVERSE REACTIONS Side effects are generally due to an exaggeration of pharmacological effects of which salivation and fasciculation are the most common. Bowel cramps and diarrhea may also occur.

Neurologic: Dizziness, convulsions, loss of consciousness, drowsiness, headache, dysarthria, miosis and visual changes.
