Oxybutynin Chloride

Oxybutynin Chloride is a prescription used to treat urinary incontinence, urgency, and frequency in people with unstable bladder conditions. This type of condition is called overactive bladder (OAB). OAB causes a sudden urge to urinate. The urge may be difficult to stop and it may lead to the involuntary loss of urine. Some symptoms of OAB may be:

  • Awaken 2 or more times in the night to urinate
  • Urinate frequently usually 8 or more times in 24 hours
  • Feel a sudden urge to urinate that’s difficult to control

This medication relaxes the muscles in the bladder. It is to help lessen problems of urgency and frequent urination.

Oxybutynin Chloride may also be used to treat bedwetting or nocturnal enuresis associated with an overactive bladder in children aged 5 years and over. This is used in combination with other non-drug therapy. It is only when other approaches have not been successful. Bedwetting or nocturnal enuresis refers to the unintentional passage of urine during sleep. It is the medical term for wetting, whether in the clothing during the day or bed at night.

The Food and Drug Administration (FDA) has already approved this medication. This product is supplied as tablets for oral use. Each tablet contains Oxybutynin Chloride as an active ingredient. It is a white crystalline solid that is readily soluble in water but relatively insoluble in alkalis. This is available in the dosage forms of 5 mg, 10 mg, and 15 mg. Oxybutynin Chloride belongs to the class of medications called an anticholinergic or antimuscarinic muscle relaxant. This helps lessen your sudden need to urinate and leaking in between bathroom visits.

How does Oxybutynin Chloride work?

Oxybutynin Chloride works by relaxing the involuntary muscle that is found in the wall of the bladder. The detrusor muscle can sometimes contract in uncontrollable spasms. This is often referred to as having an overactive or unstable bladder. The overactive detrusor muscle can cause an increase in the number of times you need to pass urine. It also includes involuntary leakage of urine and uncontrollable urges to pass urine.

By relaxing the detrusor muscle, Oxybutynin Chloride lessens unstable and involuntary contractions of the bladder. Thereby, it increases the capacity of the bladder to hold urine. This, in turn, decreases the need to pass urine.

How to use Oxybutynin Chloride?

The prescribed dosage is based on your medical condition, age, and response to the treatment. You must take this medication exactly as it is prescribed. For the best benefit from this product, take it regularly. Do not suddenly stop taking this medication without the consent of your doctor. It may cause another complication or may worsen your current condition.

Oxybutynin Chloride is usually taken two to three times a day. It is to be taken by mouth with a full glass of water. Swallow the tablet as a whole. Do not break, crush, or chew it as directed by your doctor. You may take each dose with or without a meal. To help you remember, take it at the same time and in the same way each day.

You may notice some improvement in your symptoms within the first two weeks of treatment. However, it may take six to eight weeks to experience the full benefit of this drug. Inform your doctor if your condition gets worse or does not improve.

If you missed a dose, take it as soon as you remember it. If it is almost time for your next dose, skip the missed dose and follow your regular schedule. Do not double the dose to make up for the missed dose
