LYRINEL XL is a prescription medication primarily used in the treatment of overactive bladder symptoms, such as a strong need to urinate with leaking or wetting accidents (urge urinary incontinence), a strong need to urinate right away (urgency), and urinating often (frequency). It belongs to a class of drugs known as antimuscarinics or anticholinergics, which work by relaxing the muscles in the bladder to help decrease urinary urgency, frequency, and incontinence episodes. LYRINEL XL is formulated as an extended-release tablet, designed to release the medication slowly over time, allowing for once-daily dosing. It is important for patients to follow their healthcare provider's instructions regarding dosage and administration to minimize potential side effects and achieve the best possible symptom control.
