Fesoterodine (fesoterodine fumarate) — Uses, Dosage, Side Effects & Safety

Drug class: Antimuscarinic (Anticholinergic) agent

Overview

Fesoterodine is a prescription medication used to treat symptoms of overactive bladder, such as frequent urination, urgency, and urge incontinence (leaking urine). It works by relaxing the muscles in the bladder, helping to reduce sudden urges to urinate and the number of times you need to go to the bathroom. This medicine belongs to a group of drugs called antimuscarinics or anticholinergics. By blocking certain nerve signals to the bladder, fesoterodine helps control bladder contractions and improves your ability to hold urine. Key points for patients: Fesoterodine is usually taken once daily, with or without food. It may take a few weeks to notice the full benefit. Common side effects include dry mouth and constipation. Always follow your healthcare provider’s instructions and tell them about any other medicines you are taking.
