How to Order in the USA	With a valid prescription via licensed pharmacy

Alopurinol (allopurinol) is a long-established prescription medication in the United States used to control elevated uric acid levels. Unlike medicines that treat pain during a gout attack, Alopurinol works by reducing the production of uric acid over time, helping prevent future flares, dissolve tophi, and protect kidneys from uric acid deposition. In the U.S., Alopurinol is typically dispensed as 100 mg and 300 mg oral tablets, and dosing is individualized under a clinician’s guidance.

Because Alopurinol modifies uric acid production rather than providing immediate pain relief, it is most effective as a long-term urate-lowering therapy (ULT). U.S. guidelines emphasize starting with a low dose and titrating gradually to reach a target serum urate of less than 6 mg/dL (and often under 5 mg/dL for individuals with tophaceous gout). Therapy is commonly combined with an anti-inflammatory prophylactic agent at initiation to reduce the risk of flare-ups.

Allopurinol at a glance

Allopurinol is a xanthine oxidase inhibitor. By inhibiting xanthine oxidase, it reduces the conversion of hypoxanthine and xanthine into uric acid. Lowering urate decreases the formation of monosodium urate crystals, which drive gout flares and can form deposits (tophi) in joints and tissues. Key uses in the USA include:

• Long-term control of hyperuricemia in gout
• Reduction of tophi burden over time
• Prevention of recurrent uric acid kidney stones
• Prophylaxis against tumor lysis syndrome (TLS)–related hyperuricemia during certain cancer treatments
• Adjunctive management of hyperuricosuria in select metabolic conditions

Common brands historically associated with allopurinol in the U.S. include Zyloprim (tablets). Most patients receive generic allopurinol, which is widely available and cost-effective.

How much does Alopurinol cost in the USA?

Generic allopurinol is generally affordable in the United States. Prices vary by dosage, pharmacy, and insurance coverage. Many retail and mail-order pharmacies offer competitive pricing and discount programs, and copays may be low for those with insurance. Your out-of-pocket cost depends on factors like your plan’s formulary, deductibles, and whether you use in-network pharmacies or mail-order services. For the most accurate pricing, check with your local pharmacy or your plan’s preferred mail-order provider.

Remember that Alopurinol is taken regularly for prevention rather than for immediate symptom relief. Because dosing is individualized and titrated, prescription quantities and refill intervals may vary based on your clinician’s plan and your serum urate results.

Where can I buy Alopurinol in the USA?

In the United States, Alopurinol is a prescription medication. You can obtain it from:

• Local community pharmacies (chain or independent)
• Mail-order or specialty pharmacies associated with your insurance plan
• Telehealth services that, when appropriate, can issue a valid U.S. prescription after a medical evaluation

To start therapy, consult a licensed healthcare professional who can confirm that Alopurinol is right for you, consider your medical history, and provide dosing guidance. If your clinician prescribes Alopurinol, you can fill it at your preferred U.S. pharmacy.

What is Alopurinol?

Alopurinol is a urate-lowering medication that decreases uric acid production. It is not an analgesic and does not relieve acute gout pain directly. Instead, it reduces the frequency and severity of future flares by preventing crystal formation. Benefits typically build over weeks to months, and the risk of flares gradually declines as uric acid remains controlled.

Appropriate candidates often include people with recurrent gout flares, tophi, chronic kidney disease (with careful dose adjustment), nephrolithiasis due to uric acid, or those at risk of rapid uric acid rise during chemotherapy.

How Alopurinol works

Allopurinol and its active metabolite oxypurinol inhibit xanthine oxidase, the enzyme responsible for the final steps of urate synthesis. This leads to lower serum urate and reduces the supersaturation that triggers urate crystal deposition in joints, tendons, and kidneys. Over time:

• Existing crystals can dissolve, reducing tophi and joint inflammation triggers
• The risk of acute gout flares decreases
• Urinary uric acid lowers, reducing uric acid stone formation risk

Because crystal mobilization can transiently provoke flares early in treatment, guidelines recommend anti-inflammatory prophylaxis (e.g., low-dose colchicine, an NSAID if appropriate, or low-dose corticosteroid) during initiation and dose titration.

Indications and who may benefit

Common U.S. indications for Alopurinol include:

• Long-term management of hyperuricemia in gout (including tophaceous gout)
• Prevention of recurrent uric acid nephrolithiasis (kidney stones)
• Tumor lysis syndrome prophylaxis in at-risk oncology patients

Allopurinol may also be considered in certain rare or inherited disorders associated with excessive uric acid production. The decision to use Alopurinol should be individualized and made in consultation with a healthcare professional.

Dosage and administration

Always follow your clinician’s instructions. Typical principles used in U.S. practice include:

• Start low, go slow: a common starting dose is 100 mg once daily (sometimes lower in chronic kidney disease)
• Titrate in 100 mg increments every 2–5 weeks based on serum urate and tolerability
• Target serum urate is usually below 6 mg/dL (below 5 mg/dL may be considered for severe or tophaceous gout)
• Maximum daily doses can be up to 800 mg in divided doses in select patients under medical supervision

Renal dosing: Alopurinol and its active metabolite are renally cleared. Clinicians typically adjust dosing in chronic kidney disease and monitor more closely. Do not alter your dose without professional guidance.

Administration: Alopurinol tablets are taken by mouth. Many patients take the dose once daily after food to minimize stomach upset. Adequate hydration is recommended. If doses are divided, your clinician will specify timing.

Starting therapy and managing gout flares

When Alopurinol is initiated, crystal mobilization can precipitate flares during the first weeks to months. To help reduce this risk, your clinician may prescribe:

• Low-dose colchicine (e.g., 0.6 mg once or twice daily if tolerated and not contraindicated)
• Alternatively, an NSAID (if appropriate) or low-dose corticosteroid

If a flare occurs while taking Alopurinol, do not stop the medication unless directed by your clinician. Stopping may lead to rebound increases in uric acid. Instead, contact your healthcare professional for appropriate flare management while continuing long-term urate lowering.

Safety information and potential side effects

Many people tolerate Alopurinol well. As with any medication, side effects can occur. Contact your clinician promptly if you experience unusual or severe symptoms.

Common or mild effects

• Gastrointestinal upset (nausea, diarrhea)
• Rash or mild skin reactions
• Drowsiness or headache
• Changes in liver function tests

Serious reactions: allopurinol hypersensitivity syndrome (AHS)

Rarely, severe hypersensitivity reactions can occur, including serious skin reactions such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Seek urgent medical help if you develop:

• Widespread or rapidly worsening rash
• Blistering or peeling skin, mouth sores
• Fever, swollen lymph nodes
• Facial swelling, difficulty breathing

Risk factors for severe cutaneous adverse reactions may include certain genetic backgrounds (e.g., HLA-B*58:01 positivity), chronic kidney disease, and starting at higher doses. In the U.S., HLA-B*58:01 testing may be considered in patients of Southeast Asian descent (e.g., Han Chinese, Thai, Korean) and African American patients, especially when chronic kidney disease is present. Your clinician can advise whether testing is appropriate for you.

Drug interactions

Alopurinol can interact with certain medications. Always provide your healthcare professional and pharmacist with a complete list of your prescription drugs, over-the-counter medications, vitamins, and supplements. Notable interactions may include:

• Azathioprine or mercaptopurine: doses of these drugs often require major reduction (e.g., to 25–33% of usual) and close monitoring due to increased risk of toxicity
• Warfarin: potential enhancement of anticoagulant effect; monitor INR more closely when initiating or adjusting Alopurinol
• Theophylline: serum levels may increase; monitoring can be considered
• Diuretics (e.g., thiazides): may increase risk of adverse effects including hypersensitivity in some patients
• Amoxicillin/ampicillin: may be associated with higher incidence of rash when used with Alopurinol

This is not a complete list. Your healthcare professional will determine appropriate monitoring and dose adjustments if needed.

Use in special populations

Pregnancy and breastfeeding

Data on Alopurinol in pregnancy are limited. Use only if the potential benefits outweigh risks and after clinician consultation. Small amounts may pass into breast milk; discuss with your healthcare professional to evaluate safety for you and your infant.

Kidney or liver impairment

Because allopurinol and its metabolite are primarily renally eliminated, dose adjustments and closer monitoring are typically used in chronic kidney disease. In liver disease, clinicians may monitor liver function tests and adjust treatment as appropriate.

Older adults

Older adults often have comorbid conditions and take multiple medicines. Careful dosing and monitoring help minimize interactions and adverse effects.

Monitoring and treatment goals

U.S. gout management strategies typically include the following goals and monitoring steps:

• Serum urate target: usually less than 6 mg/dL; under 5 mg/dL in tophaceous disease
• Lab monitoring: serum urate at baseline and periodically during titration, as well as kidney function and liver enzymes as clinically indicated
• Clinical assessment: flare frequency, tophi size/number, joint symptoms, and medication tolerance

Reaching and maintaining the target is essential to dissolving crystals and preventing long-term complications. Do not discontinue Alopurinol without your clinician’s guidance.

Kidney stones and urinary considerations

In people prone to uric acid kidney stones, lowering urinary uric acid with Alopurinol can help reduce stone formation. Your clinician may recommend additional strategies such as adequate hydration and, if needed, urine alkalinization to maintain a higher urine pH. Diet and lifestyle changes can also support stone prevention.

Tumor lysis syndrome (TLS) prophylaxis

TLS can occur when rapid cell breakdown releases large amounts of uric acid during certain cancer treatments. In select patients, clinicians may use Alopurinol to lower uric acid production and help prevent complications. Dosing and timing vary with chemotherapy regimens, kidney function, and uric acid levels. In some cases, alternative agents (e.g., rasburicase) may be used. Your oncology team will determine the most appropriate strategy for you.

Lifestyle tips while taking Alopurinol

• Hydration: Drink adequate fluids unless advised otherwise by your clinician
• Diet: Consider limiting high-purine foods (e.g., organ meats, certain seafood), moderating alcohol (especially beer and spirits), and reducing sugar-sweetened beverages
• Weight and activity: Aim for a healthy weight and regular physical activity as advised by your healthcare professional
• Adherence: Take Alopurinol as prescribed, even when you feel well, to maintain target serum urate
• Flare plan: Ask your clinician for a personalized flare action plan

How to take Alopurinol correctly

Take Alopurinol exactly as prescribed. Many patients take the dose after a meal to reduce stomach upset. If you miss a dose, take it when you remember unless it is near the time for your next dose. Do not double up without guidance. Store tablets at room temperature away from moisture and heat, and keep out of reach of children and pets.

When to contact your clinician

• New or worsening rash, blisters, or skin peeling
• Signs of allergic reaction: swelling of face/lips/tongue, difficulty breathing
• Unusual fatigue, dark urine, or yellowing of the skin/eyes
• Frequent flares or persistent gout symptoms despite adherence
• Any side effects that concern you
