Oxytrol (Oxybutynin) – Transdermal: Uses, Side Effects, Dosages, Interactions

What Is Oxytrol?

Oxytrol (oxybutynin) is a transdermal patch used to treat an overactive bladder. It belongs to a drug class known as antispasmodics. Oxybutynin is an anticholinergic drug.

It works by blocking the actions of a neurotransmitter (acetylcholine) on the muscle. It relaxes the bladder muscle, improves its capacity, reduces bladder spasms, and reduces urination urge and frequency. Oxytrol is available both with a prescription and over-the-counter (OTC).
