Allopurinol: A Practical Guide for Gout and Uric Acid Management

When working with Allopurinol, a medication that lowers uric acid by blocking the enzyme xanthine oxidase. Also known as Aloprim, it’s used to prevent gout attacks and treat kidney stones caused by uric acid buildup.

Allopurinol belongs to the class of xanthine oxidase inhibitors, drugs that stop the conversion of purines into uric acid. By inhibiting this pathway, the drug reduces the concentration of uric acid, the crystal‑forming substance that triggers joint inflammation. When uric acid levels stay low, the risk of gout, a painful arthritis caused by uric acid crystals in joints drops dramatically. The same principle helps manage hyperuricemia, a condition of chronically elevated uric acid in the blood, which can lead to kidney stones and renal impairment if untreated.

Key Points About Allopurinol

Most patients start with a low dose—usually 100 mg daily—to gauge tolerance, then increase by 100 mg each week until serum uric acid falls below 6 mg/dL. The drug works best when taken after a meal, which reduces stomach upset. People with reduced kidney function often need a lower maintenance dose because the medication and its metabolites are cleared renally; a typical adjustment is 50 mg daily for moderate impairment and 25 mg for severe cases. Monitoring kidney labs every few months helps catch any buildup early.

Common side effects include mild rash, nausea, and occasional headache. A rare but serious reaction is Stevens‑Johnson syndrome, which usually presents as a widespread skin rash and fever; anyone showing these signs should stop the drug and seek care right away. Allopurinol can also interact with drugs that affect purine metabolism, such as azathioprine and mercaptopurine, increasing the risk of bone‑marrow suppression. Keeping a medication list handy and informing your pharmacist ensures safe combinations.
