Read the following passage and mark the letter A, B, C, or D to indicate the answer to each of the question.

When lifestyle changes aren’t enough, the next step may be to take medicine. Your health care provider can tell you about special drugs for overactive bladder (OAB).

There are several drug types that can relax the bladder muscle. These drugs, like anti-muscarinics and beta-3 agonists, can help stop your bladder from squeezing when it’s not full. Some are taken as pills, by mouth. Others are gels or a sticky transdermal patch to give you the drug through your skin.

Anti-muscarinics and betta-3 adrenoceptor agonists can relax the bladder muscle and increase the amount of urine your bladder can hold and empty. Combination drugs, like using both antimuscarinics and - betta-3 adrenoceptor agonists together may help control OAB when one option alone isn’t working.

Your health care providers will want to know if the medicine works for you. They will check to see if you get relief or if the drug causes problems, known as side effects. Some people get dry mouth and dry eyes, constipation, or blurred vision. If one drug you try doesn’t work, your health care provider may ask you to take different amounts, give you a different one to try, or have you try two types together. Lifestyle changes and medicine at the same time help many people.
