Fenpiverinium bromide works by relaxing the smooth muscles in the gastrointestinal and genitourinary systems, which can help to relieve spasms and associated pain. It is typically administered in the form of an injection, and the usual dosage for adults is 1-2 ml, up to three times a day.
As with any medication, fenpiverinium bromide may cause side effects in some people. Common side effects may include dry mouth, blurred vision, constipation, and urinary retention.
