Zyloprim is a brand name for the medication allopurinol, an oral pill used to lower high levels of uric acid in the blood. Allopurinol belongs to the class of xanthine oxidase inhibitors and is commonly prescribed for conditions such as gout and certain types of kidney stones. In Hong Kong, Zyloprim is a prescription-only medication regulated by the Department of Health. It is available in two strengths: 100 mg and 300 mg tablets.
Allopurinol blocks the enzyme xanthine oxidase, which is responsible for converting purines (found in many foods) into uric acid. By inhibiting this enzyme, Zyloprim reduces the production of uric acid, helping to prevent its accumulation in joints and kidneys. Lower uric acid levels lessen the risk of gout flares and can slow the formation of uric-acid kidney stones.
Zyloprim is FDA- and EMA-approved for the following indications, which are also recognized by Hong Kong health authorities:
These uses are based on the drug’s ability to lower uric acid rather than directly relieving pain; pain relief in gout results from the reduction of crystal-induced inflammation.
These reactions are usually mild and resolve without discontinuing therapy.
If any severe skin rash, jaundice, or persistent abdominal pain occurs, seek medical attention promptly.
General Advice: Always provide a full medication list-including over-the-counter drugs, supplements, and herbal products-to the prescribing clinician.
Regular follow-up appointments allow dose adjustments to maintain uric acid below 6 mg/dL (or below 5 mg/dL in patients with tophi).

Yes, Zyloprim is often initiated alongside colchicine or an NSAID to prevent an initial gout flare. Both drugs can be taken together, but dosing intervals should follow the prescribing clinician’s instructions.
Allopurinol can trigger immune-mediated skin reactions in a small proportion of patients. The rash typically appears within the first few weeks. If it spreads or is accompanied by fever, seek medical care promptly.
Patients with mild to moderate renal impairment can use Zyloprim, but the starting dose is usually reduced to 100 mg daily, and dosing is adjusted based on kidney function and uric-acid response.
Most patients see a measurable decline in serum uric acid within 2-3 days, with optimal control achieved after 2-4 weeks of steady dosing.
Yes, Zyloprim is legal for personal use in most countries when you possess a valid prescription. Carry the medication in its original packaging with the prescription label visible.
Limiting high-purine foods (e.g., red meat, organ meats, certain seafood) and reducing alcohol intake, especially beer, helps maximize the drug’s effectiveness.
Take the missed dose as soon as you remember, unless it is close to the time of your next scheduled dose. Do not double-dose; simply resume the regular dosing schedule.
Store the tablets in a cool, dry place away from direct sunlight. In very hot environments, keep them inside a temperature-controlled cabinet or a sealed container to protect from heat and humidity.
Both drugs lower uric acid, but they belong to different classes. Allopurinol (Zyloprim) is a xanthine oxidase inhibitor with a long safety record, while febuxostat is a newer, non-purine inhibitor. Choice depends on individual kidney function, tolerance, and physician recommendation.
