How long before allopurinol starts working?

Allopurinol may begin lowering uric acid after a few weeks, but full benefits, like reduced gout attacks or fewer kidney stones, often occur after several months of consistent use. Continue daily even when you feel fine.

Can alcohol be consumed while taking allopurinol?

Alcohol may increase uric acid levels, potentially counteracting treatment. Limiting alcohol, especially beer and spirits, is advisable to support treatment effectiveness.

Is allopurinol used for treating gout flares?

No. Its purpose is preventive, not to relieve acute flare-ups. Other medications such as NSAIDs or colchicine are used for flares.

Why might gout worsen when starting allopurinol?

Starting allopurinol may initially trigger gout flare-ups as uric acid levels shift. Healthcare providers often prescribe anti-inflammatory prophylaxis during initiation to reduce this risk.

How often should uric acid be checked?

Regular blood tests are important, typically every few months, to ensure uric acid reaches target levels. Dosage may be adjusted based on results.

How do xanthine oxidase inhibitors differ from other gout drugs?

Xanthine oxidase inhibitors decrease uric acid production, unlike uricosuric drugs that help the body excrete uric acid. They are a common first choice for long-term control.

Zyloprim / Alloril (generic name: allopurinol) is a long-term medication used to prevent recurrent gout attacks, kidney stones, and manage high uric acid levels, especially in people receiving chemotherapy. It belongs to a class of medications called xanthine oxidase inhibitors. Allopurinol works by reducing the production of uric acid in the body, helping to prevent the buildup that leads to painful gout flares and kidney stones. This medication must be taken regularly, even if symptoms are not present, to maintain its preventive effect. Read more about this function at MedlinePlus.

Usual dosage

It is important to follow the dosage instructions printed on the label of the box. Treatment generally starts at a low dose, commonly 100 mg daily for gout, then increased gradually (by 100 mg weekly) until uric acid levels are controlled, up to a maximum of 800 mg daily. Those with kidney impairment often begin at 50 mg daily, with further adjustments based on kidney function. For managing high uric acid during cancer treatment, doses may range from 300 mg to 800 mg daily. Always take after meals with sufficient fluids. If a dose is missed, take the next dose at the usual time. Do not double dose. Important: continue daily even when there are no symptoms; stopping abruptly may reduce effectiveness or cause flare-ups.

Standard storage

Store at room temperature between 15 °C and 25 °C (59 °F and 77 °F). Protect from heat, moisture, and direct light. Keep in its original container, out of reach of children. Do not use after the expiration date (last day of the printed month). Dispose of unused medicine safely; do not flush it down water systems, but return to a pharmacy for proper disposal.

The information leaflet that comes with the medication includes full details about possible side effects. Be sure to read and understand these, and if there are any questions, discuss them with a healthcare provider.

If a sudden allergic reaction occurs after taking Zyloprim / Alloril, such as swelling of the face, tongue, or throat; difficulty breathing; hives; or skin peeling, seek emergency medical care immediately.

Use during pregnancy or breastfeeding should be discussed with a healthcare provider; the benefits and risks must be carefully weighed.

Most people taking Zyloprim / Alloril do not experience serious side effects. This medication is prescribed when its benefit outweighs potential risks.

Reported side effects include rash, nausea, stomach upset, drowsiness, headache, and an initial increase in gout attacks. Serious reactions such as blood abnormalities, liver problems, or severe rash (e.g., Stevens-Johnson syndrome) are rare but require immediate medical attention.

If side effects persist or worsen, consult a healthcare provider or pharmacist.

Alloril is approved for preventing gout attacks by lowering blood uric acid levels. It also helps prevent recurrence of uric acid kidney stones and treats hyperuricemia (high uric acid) in patients undergoing chemotherapy or those with enzyme disorders. Gout involves sudden joint pain and swelling (often in the big toe), kidney stones can cause severe back or abdominal pain, and elevated uric acid increases risk of both—treatment reduces these risks.

Allopurinol may begin lowering uric acid after a few weeks, but full benefits, like reduced gout attacks or fewer kidney stones, often occur after several months of consistent use. Continue daily even when you feel fine.
