Trospium is prescribed for the management of overactive bladder, a condition characterized by involuntary contractions of the bladder muscles that lead to frequent urination, a compelling need to urinate, and difficulty controlling urination. Trospium belongs to a group of drugs known as antimuscarinics. Its mode of action involves the relaxation of the bladder muscles, effectively preventing episodes of urgent, frequent, or involuntary urination.
Uses and Dosage
Trospium is available in both tablet and extended-release capsule forms for oral administration. Typically, the tablet is taken twice a day, either on an empty stomach or 1 hour prior to meals, although in some cases it may be taken once daily at bedtime. The trospium extended-release capsule is generally taken once a day in the morning with water, on an empty stomach, and at least 1 hour before having a meal. To ensure consistent adherence, aim to take trospium at roughly the same time each day.
Take trospium exactly as prescribed—do not exceed or reduce the dosage, and do not take it more frequently than directed by your doctor.
