SIDE EFFECTS

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Adverse reactions to neostigmine methylsulfate are most often attributable to exaggerated pharmacological effects, in particular, at muscarinic receptor sites. The use of an anticholinergic agent, e.g., atropine sulfate or glycopyrrolate, may prevent or mitigate these reactions.

Quantitative adverse event data are available from trials of neostigmine methylsulfate in which 200 adult patients were exposed to the product. The following table lists the adverse reactions that occurred with an overall frequency of 1% or greater.

System Organ ClassAdverse Reaction
Cardiovascular Disordersbradycardia, hypotension, tachycardia/heart rate increase
Gastrointestinal Disordersdry mouth, nausea, post-procedural nausea, vomiting
General Disorders and Administration Site Conditionsincision site complication, pharyngolaryngeal pain, procedural complication, procedural pain
