Precautions

It is very important that your doctor check the progress of you or your child at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you or your child should continue to use it.

This medicine may cause a serious type of allergic reaction called angioedema. Angioedema may be life-threatening and requires immediate medical attention. Call your doctor right away if you or your child have a rash, itching, a large, hive-like swelling on the face, eyelids, lips, tongue, throat, hands, legs, feet, or sex organs, trouble breathing, or chest tightness while you are using this medicine.

Oxybutynin may cause anxiety, confusion, irritability, sleepiness or unusual drowsiness, or hallucinations (seeing, hearing, or feeling things that are not there). These symptoms are more likely to occur when you begin taking this medicine, or when the dose is increased. If you or your child have these symptoms, tell your doctor right away.

This medicine will add to the effects of alcohol and other CNS depressants (medicines that slow down the nervous system, possibly causing drowsiness). Some examples of CNS depressants are antihistamines or medicine for hay fever, other allergies, or colds, sedatives, tranquilizers, or sleeping medicine, prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you or your child are using this medicine.

This medicine may cause your eyes to become more sensitive to light than they are normally. Wearing sunglasses and avoiding too much exposure to bright light may help lessen the discomfort.

This medicine may cause some people to become dizzy, drowsy, or have blurred vision. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy, not alert, or not able to see well.

Oxybutynin may make you sweat less, causing your body temperature to increase. Use extra care not to become overheated during exercise or hot weather while you or your child are taking this medicine, since overheating may result in heat stroke. Also, hot baths or saunas may make you feel dizzy or faint while you or your child are taking this medicine.

Your mouth, nose, and throat may feel very dry while you or your child are taking this medicine. For temporary relief of mouth dryness, use sugarless candy or gum, melt bits of ice in your mouth, or use a saliva substitute. However, if your mouth continues to feel dry for more than 2 weeks, check with your medical doctor or dentist. Continuing dryness of the mouth may increase the chance of dental disease, including tooth decay, gum disease, and fungus infections.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
