Let's take a minute to talk about your medication. This is oxybutynin, and you should take it as directed by your doctor, at the same time each day. Oxybutynin helps relieve symptoms from an overactive bladder, like having to go frequently and losing control at times. This medicine is well-tolerated, but some side effects can occur, like drowsiness or mildly blurry vision. So don't do activities that require you to be alert, like driving, until you know how it affects you. These are normal if they are mild and should go away. If these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist. To reduce side effects, you should ask your doctor or pharmacist before taking any new medicines, even if they don't require a prescription. Also, be careful drinking alcohol, because it can make side effects worse. Lastly, your body may sweat less, so you could become overheated easier than before. So, be careful in hot weather and stay cool. As with any medicine, in rare cases, more serious side effects can occur. You should call your doctor right away if you notice any unusual changes to your body, like swelling, especially in your face or throat, because this could be an allergic reaction. For best results, take your medicine as prescribed, and let your doctor know if you don't get the results with bladder control that you were expecting.
