Known Drug Interactions

7.2 Use with Cholinomimetics and Other Cholinesterase Inhibitors A synergistic effect may be expected when cholinesterase inhibitors are given concurrently with succinylcholine, similar neuromuscular blocking agents, or cholinergic agonists such as bethanechol.

Mechanism: Both drugs work in a similar way to increase a specific chemical in the body. Taking them together can make this effect much stronger than intended.

7.2 Use with Cholinomimetics and Other Cholinesterase Inhibitors A synergistic effect is expected when cholinesterase inhibitors are given concurrently with succinylcholine, other cholinesterase inhibitors, similar neuromuscular blocking agents or cholinergic agonists such as bethanechol [see Clinical Pharmacology ( 12.3 )] .

Mechanism: Both drugs increase the activity of a specific chemical in the body's nervous system. Taking them together can make their effects much stronger than usual.

Bethanechol treats urinary retention (trouble emptying your bladder). Official labeling lists 8 commonly reported side effects, including Abdominal cramps or discomfort, Nausea, Diarrhea.

Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. Voluntary reports accumulate over the lifetime of a drug and reflect wide-ranging clinical use. The database also lists 2 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated minor severity. NADAC pricing from CMS shows a generic unit cost of $0.18.

Report counts do not establish causation, a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information are separate source-record fields.
