What is Oxybutynin Chloride Er?

Oxybutynin ER (extended-release) is a prescription medication used to treat overactive bladder (OAB) — a condition that causes sudden, urgent urges to urinate, frequent urination, and sometimes leakage. It works by relaxing the muscles of the bladder, reducing those sudden urges and giving you much better control throughout the day. Unlike the immediate-release version taken multiple times a day, oxybutynin ER is taken just once daily, making it easier to stick to your routine. Doses typically start at 5 mg or 10 mg per day and can be adjusted up to 30 mg based on how your body responds. A licensed provider can determine if oxybutynin ER is right for you and write a prescription online. Through Rx.com, you can see a provider, get your prescription, and find the lowest price at pharmacies near you — all in one place.

What is oxybutynin chloride ER and how does it work?

Oxybutynin chloride ER (extended-release) is an anticholinergic, also called an antimuscarinic or antispasmodic, medication. It works by relaxing the muscle of the bladder wall, which helps reduce sudden bladder contractions. This eases the symptoms of overactive bladder (OAB), including a strong, sudden urge to urinate, urinating too often, and leaking urine with that urgency (urge urinary incontinence). The extended-release form is designed to release the medicine slowly over the day, so it is usually taken once daily.

It is FDA-approved for overactive bladder in adults and is also approved for children age 6 and older who have bladder overactivity related to a neurological condition, such as spina bifida. It is sometimes used off-label for excessive sweating (hyperhidrosis). This information is educational and is not medical advice; your provider can tell you whether this medication is right for you.

How much does oxybutynin chloride ER cost without insurance?

Oxybutynin chloride ER is available as a generic, which typically makes it far more affordable than a brand-name product. Even so, the cash price without insurance is not the same everywhere. Pharmacies set their own prices, and the difference between two stores in the same town can be significant, so it pays to compare before you fill.

That is where Rx.com helps. Enter your ZIP code above to see today's price at pharmacies near you and get a free discount coupon you can use whether or not you have insurance. There is no membership fee to compare prices or use the coupon.

Alternatives and related medications

Oxybutynin chloride ER is the generic equivalent of the brand Ditropan XL. The same active ingredient also comes as immediate-release oxybutynin, which is taken more than once a day.

Several other prescription medicines are used for overactive bladder. If oxybutynin is not a good fit, your provider may discuss other anticholinergic options such as tolterodine, solifenacin, or trospium, or a different type of medication called a beta-3 agonist, mirabegron. You can compare prices for any of these on Rx.com. Only your provider can decide which medication is best for you.

Safety information and side effects

The most common side effect of oxybutynin chloride ER is dry mouth, which tends to be dose-related. Other anticholinergic effects can include constipation, blurred vision, drowsiness, dizziness, and difficulty urinating (urinary retention). In some people, especially older adults, it can cause confusion or hallucinations, so caution is advised in the elderly. Because the medication reduces sweating, it can raise the risk of overheating (heat prostration) in hot weather or with heavy activity.

Oxybutynin chloride ER should not be used by people with urinary retention, certain serious stomach or intestinal conditions (gastric retention or severe GI motility disorders), or uncontrolled narrow-angle glaucoma. Rare but serious swelling of the face, lips, tongue, or throat (angioedema) has been reported. The medication may impair your ability to drive or operate machinery, and alcohol or other sedating medicines can add to drowsiness. Use caution if you have liver or kidney problems. This is not a complete list of warnings, and it is not medical advice. Talk with your doctor or pharmacist about your full health history before starting this medication.
