This is a long-acting form of oxybutynin that is used to treat overactive bladder and urinary conditions. It relaxes the muscles in the bladder to help decrease problems of urgency and frequent urination. Oxybutynin belongs to a class of drugs known as antispasmodics.
This medication is also used to treat children 6 years of age and older who have an overactive bladder due to certain nerve disorders (e.g., spina bifida).
How To Use
Take this medication by mouth, usually once a day, or as directed by your doctor. It may be taken with or without food. The dosage is based on your medical condition and response to therapy. The length of treatment is determined by your doctor who may suggest periodic trials off the drug to evaluate whether you still need to be taking it.
Swallow this medication with the help of liquids. Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day.
