What is Zyloprim?

Zyloprim is an oral tablet containing a drug, with antigout and antihyperuricemic agents, called allopurinol. We carry the brand name Zyloprim and its generic alternative in 100mg, 200mg, and 300mg.

Zyloprim is a medication used to treat gout and certain types of kidney stones. These conditions are often times caused by uric acid levels being too high. Usually, this is because the kidneys don’t know how to eliminate the uric acid efficiently, which may be a result of being overweight, having diabetes, taking certain diuretics, or drinking too much alcohol. Uric acid is made naturally in the body during the breakdown of purine, which is found in foods.

Additionally, this medication may be used to treat and prevent high levels of uric acid levels in patients undergoing cancer chemotherapy. Cancer chemotherapy is a cancer-killing method, but when cancer cells die, they often release uric acid, increasing the amount the uric acid in the body. Increased uric acid can lead to gout and kidney problems.

Zyloprim (allopurinol) is effective at treating gout, kidney stones, and high levels of uric acid because it is able to reduce the amount of uric acid being produced in the body.

You should only take this medication the way that you have been directed to by your doctor.
