Allopurinol is a prescription drug that helps lower the uric acid in the body. It is used for:

  • Long-term management and prevention of chronic gout
  • Prevention of certain types of kidney stones due to uric acid build-up
  • Reducing uric acid formation when a build-up is predictable
  • Treatment of enzyme disorders that results in the overproduction of uric acid

Allopurinol belongs to the group of drug known as xanthine oxidase inhibitors. It works by reducing the production of uric acid in the body. Excessive level of uric acid in the blood is produced by xanthine oxidase enzyme.  The uric acid forms crystals in joints and tissues causing pain and inflammation. It can also cause kidney stones and other kidney diseases. 

Why Buy Allopurinol?

Allopurinol is FDA-approved for long-term prevention of gout. It works well in preventing a gout attack. It’s also cheaper compared with other gout medications. It’s available as generic and brand names like Zyloprim. Both versions contain the same active ingredient and have the same mechanism of action.

How to Take Allopurinol?

Allopurinol comes as a tablet that you need to take orally. Take it exactly as directed. Your dose depends on your condition and the severity of your condition. The usual recommended dose is one tablet once or two times a day. Your doctor may start giving you a lower dose at the beginning of your treatment and gradually increase not more than once a week.

Take it with plenty of water right after a meal. Swallow the tablet whole. Do not break or crush the tablet. Take the medicine at the same time each day.

Things to Remember
