Allopurinol is a drug used for the treatment of gout and some types of kidney stones, as well as to prevent increased levels of uric acid (in patients receiving chemotherapy). You should drink plenty of fluids during the day to prevent the formation of stones. Stop taking Allopurinol and contact your doctor right away in case of experiencing skin rash. This medicine can make it easier for you to bleed as it lowers the level of blood cells responsible for fighting infection in your body. Your blood will need to be tested regularly so that the doctor is able to monitor your condition. Drinking alcohol may worsen the symptoms or side effects.
Before you start taking this medicine tell your doctor about having liver or kidney disease, diabetes, congestive heart failure, high blood pressure, or in case you received or are currently receiving chemotherapy. This medicine is FDA pregnancy category C - it can be harmful to an unborn baby and pass into breast milk. If you are pregnant or breastfeeding, you need to talk to your doctor before getting the prescription. If you think you may have become pregnant while taking Allopurinol contact your health care provider right away.
