Monthly Cost Estimate
When it comes to managing gout, Allopurinol is the go‑to prescription for most doctors. It works by inhibiting the enzyme xanthine oxidase, which reduces the production of uric acid. Approved by the FDA in 1966, the drug is typically started at 100 mg daily and can be increased to 300 mg or more, depending on kidney function and uric acid levels. While Allopurinol is effective for many, a growing number of patients look for alternatives because of side‑effects, drug interactions, or incomplete uric‑acid control.
Why Compare Allopurinol with Other Options?
Choosing the right gout therapy isn’t a one‑size‑fits‑all decision. Factors such as kidney health, cardiovascular risk, cost, and how quickly you need pain relief all play a role. By laying out the key differences, you can decide whether to stay with Allopurinol or switch to another agent.
Top Alternatives at a Glance
- Febuxostat - another xanthine oxidase inhibitor, but with a different chemical structure.
- Probenecid - a uricosuric that helps the kidneys excrete uric acid.
- Lesinurad - usually combined with a xanthine oxidase inhibitor to boost uric‑acid clearance.
- Pegloticase - an enzyme therapy reserved for refractory gout.
Side‑Effect Profiles: What to Watch For
Allopurinol’s most common complaints are rash and mild liver enzyme elevation. Rarely, it can trigger a severe hypersensitivity reaction called DRESS syndrome, especially in patients with the HLA‑B*58:01 allele.
Febuxostat tends to cause liver enzyme spikes and, in some studies, a modest increase in cardiovascular events. Probenecid’s drawbacks revolve around kidney stones and potential drug interactions (e.g., with penicillins). Lesinurad adds a risk of acute kidney injury if not paired correctly with a xanthine oxidase inhibitor. Pegloticase can cause infusion‑related reactions and is expensive.
Effectiveness and Onset of Action
Allopurinol usually reaches steady‑state uric‑acid reduction in 2‑3 weeks. Febuxostat works a bit faster, often achieving target levels within a week. Probenecid’s effect depends heavily on kidney function and may take longer to stabilize. Lesinurad, when added to Allopurinol or Febuxostat, can shave an extra 10‑15 % off uric‑acid levels in the first month. Pegloticase can bring uric acid to normal in days, but it’s reserved for patients who have failed all oral options.
Cost Comparison (USD per month, 2025 data)
| Medication | Mechanism | Typical Dose | Onset (Weeks) | Key Side Effects | Average Monthly Cost |
|---|---|---|---|---|---|
| Allopurinol | Xanthine oxidase inhibitor | 100‑300 mg daily | 2‑3 | Rash, liver enzyme rise, DRESS (rare) | $15‑$30 |
| Febuxostat | Xanthine oxidase inhibitor | 40‑80 mg daily | 1‑2 | Liver enzymes, cardiovascular warning | $120‑$180 |
| Probenecid | Uricosuric (kidney excretion) | 250‑500 mg twice daily | 3‑4 | Kidney stones, drug interactions | $30‑$45 |
| Lesinurad | Uricosuric (enhances excretion) | 200 mg daily + XO‑inhibitor | 2‑3 | Kidney injury, liver enzymes | $250‑$350 (combined therapy) |
| Pegloticase | Uricase enzyme replacement | 8 U IV bi‑weekly | 0.5‑1 | Infusion reactions, high cost | $12,000‑$14,000 |
When to Stay on Allopurinol
If you have normal kidney function, no history of severe rash, and your uric‑acid levels drop below 6 mg/dL within a few weeks, Allopurinol remains the most cost‑effective choice. It also has the longest safety track record, which matters for chronic conditions.
When an Alternative Might Be Better
- Kidney impairment: Probenecid is less effective when eGFR < 30 mL/min, so a lower‑dose Allopurinol or Febuxostat is preferred.
- Cardiovascular risk: If you have a recent heart attack, avoid Febuxostat unless benefits outweigh the small increase in risk.
- Allopurinol hypersensitivity: Switch to Febuxostat or a uricosuric if you develop a rash that escalates.
- Inadequate uric‑acid control: Adding Lesinurad to Allopurinol can push levels lower without changing the base drug.
- Refractory gout: For patients failing two oral agents, Pegloticase offers rapid control.
Practical Tips for Switching Therapies
- Always taper Allopurinol gradually (reduce dose by 25 % every 1‑2 weeks) to avoid flare‑ups.
- Check renal function before starting Probenecid or Lesinurad.
- Order HLA‑B*58:01 testing if you belong to high‑risk ethnic groups.
- Stay hydrated - at least 2‑3 L of water daily - to reduce stone risk with uricosurics.
- Schedule a follow‑up uric‑acid test 2‑4 weeks after any medication change.
Key Takeaways
- Allopurinol is cheap, well‑studied, and works well for most patients.
- Febuxostat offers faster uric‑acid reduction but costs more and has a cardiovascular warning.
- Probenecid helps when you need extra uric‑acid excretion but requires good kidney function.
- Lesinurad is useful as an add‑on to lower uric acid further.
- Pegloticase is a last‑line, high‑cost option for difficult cases.
Frequently Asked Questions
Can I take Allopurinol and Febuxostat together?
No. Both drugs block xanthine oxidase, so combining them offers no extra benefit and raises the risk of liver toxicity.
What is the best first‑line treatment for gout if I have chronic kidney disease?
Low‑dose Allopurinol (often 50‑100 mg) is typically preferred because it’s safe down to an eGFR of 30 mL/min. Febuxostat is an alternative if Allopurinol is not tolerated.
How long should I stay on gout medication after an attack?
Guidelines suggest lifelong therapy if you have two or more attacks, to keep uric acid under 6 mg/dL and prevent joint damage.
Are there natural ways to boost the effect of Allopurinol?
Staying well‑hydrated, limiting purine‑rich foods (red meat, shellfish), and avoiding alcohol can help Allopurinol work more efficiently.
What should I do if I develop a rash while on Allopurinol?
Stop the medication immediately and contact your healthcare provider. They may order HLA‑B*58:01 testing and switch you to an alternative.

If you’re thinking about switching gout meds remember you’re not alone. Many patients start low and adjust based on kidney function and how they feel. Talk with your doctor about any rash or liver test changes and they can guide dose tweaks. Staying hydrated and watching purine intake helps any therapy work better
