Allopurinol treats attack of gout, kidney stones, raised uric acid levels, and enzyme disorders. It works by inhibiting the uric acid production in the body since it belongs to a group of drugs called xanthine oxidase inhibitors or enzyme inhibitors.


Allopurinol is a prescription medicine available as an oral tablet. Allopurinol is a Xanthine oxidase inhibitor that reduces the blood uric acid level.

Allopurinol decreases the uric acid level in the blood. Accordingly, it is used for:

  • the long-term management of primary and secondary Gout. High blood levels of uric acid in the body lead to uric acid crystals in and around the joints, medically known as Gout. Gout is an inflammatory condition characterized by swollen and painful joints.
  • the treatment of kidney stones formed due to uric acid build-up.
  • decreasing the production of uric acid during chemotherapy of certain types of cancer.
  • treating enzymatic disorders that result in excessive production of uric acid, for example, Lesch-Nyhan syndrome.

Usually, the human body produces a substance known as Urate, which is removed from the body by the kidney. However, often body starts producing an excessive amount of uric acid, which gets deposit in and around body joints in the form of uric acid crystals. Xanthine oxidase is the enzyme that plays a critical role in the production of uric acid in the human body. Allopurinol inhibits the enzyme, Xanthine oxidase, thus reducing uric acid production in the body.

Allopurinol helps relieve Gout flare up or gout attacks by inhibiting uric acid production in the body. The reduction of uric acid production by Allopurinol helps in the long-term management of Gout.

Allopurinol is a prescription medicine. Allopurinol tablets are to be taken orally with a glass of water, once a day, preferably after having food. Depending upon the blood uric acid levels, the doctor will prescribe the exact dose of Allopurinol. Allopurinol tablet can be taken at any time of the day; however, it is best to take the Allopurinol tablet daily at the same time. Drinking plenty of water daily is also highly recommended as it will aid in removing uric acid from the body.

Allopurinol tablets are available in two strengths- 100 mg and 300 mg. Usually, therapy is initiated at a low dose of 100 mg daily and may go up to 300mg a day. Depending on the blood uric acid levels and kidney function, the doctor will advise the correct dosage of Allopurinol. In patients with exceptionally high uric acid levels, the dosage may go as high as 900mg a day.
