Allopurinol reduces the production of uric acid in your body. The buildup of uric acid can cause gout or kidney stones. Allopurinol is used to treat gout and kidney stones, and to reduce uric acid levels in patients receiving cancer treatment. Allopurinol is a xanthine oxidase inhibitor. Allopurinol and its main metabolite oxypurinol decrease the level of uric acid in plasma and urine by inhibition of xanthine oxidase.

Allopurinol Tablets for Gout Treatment and Uric Acid Control

Allopurinol tablets are used to treat gout and conditions caused by high uric acid levels in the body. When uric acid builds up, it forms sharp crystals that settle in joints or kidneys, leading to painful gout attacks or kidney stones. Allopurinol tablets reduce uric acid production at the source, lowering levels in the blood and urine over time.

Many people take Allopurinol tablets as a long-term treatment to prevent repeated gout attacks, protect joints from damage, and reduce the risk of uric acid kidney stones. With consistent use, Allopurinol tablets support long-term control rather than short-term symptom masking.

You can buy Allopurinol tablets online from Pharmacy Planet after completing a short free consultation. One of our UK prescribers reviews your details to make sure the treatment is safe and suitable before approval.

What Are Allopurinol Tablets?

Allopurinol tablets are a prescription medicine that lowers uric acid levels in the body. They belong to a group of medicines called xanthine oxidase inhibitors, which block the enzyme responsible for producing uric acid.

Allopurinol tablets are commonly prescribed for people with long-term gout, repeated gout attacks, or medical conditions that cause excess uric acid to build up in the body.

What Are Allopurinol Tablets Commonly Prescribed for?

Common uses of Allopurinol tablets include:

  • Long-term treatment of gout.
  • Prevention of repeated gout flare-ups.
  • Reduction of uric acid levels in hyperuricaemia.
  • Prevention of uric acid kidney stones.
  • Control of high uric acid caused by cancer treatment or metabolic conditions.

How Do Allopurinol Tablets Work?

Allopurinol tablets work by stopping the body from producing too much uric acid. High uric acid levels lead to crystal formation in joints and kidneys, which triggers pain, swelling, and inflammation.

Once taken, Allopurinol is converted into an active substance called oxypurinol. Together, they block xanthine oxidase, the enzyme that converts purines into uric acid.

By reducing uric acid production:

  • Fewer crystals form in joints.
  • Existing deposits slowly dissolve over time.
  • The risk of future gout attacks reduces.
  • Kidney stone formation becomes less likely.

This makes Allopurinol tablets a long-term urate-lowering therapy rather than a pain relief treatment for sudden attacks.

How to Use Allopurinol Tablets?

Always take Allopurinol tablets exactly as advised by one of our UK prescribers. Swallow the tablets with water, preferably after food, to reduce stomach upset.

General Dosing Guidance:

  • Mild gout or raised uric acid: 100 mg to 200 mg daily.
  • Moderate gout: 300 mg to 600 mg daily.
  • Severe gout: up to 900 mg daily in divided doses.

The dose is usually started low and increased gradually to reduce the risk of side effects and gout flare-ups at the start of treatment.

Allopurinol tablets are taken every day, even when symptoms improve. Stopping suddenly can cause uric acid levels to rise again.

If you forget a dose, take it when you remember unless it is close to your next dose. Do not take two doses together.

Who Can Use Allopurinol Tablets?

Allopurinol tablets may be suitable for:

  • Adults with chronic gout.
  • People with frequent gout flare-ups.
  • Those with high uric acid levels, causing joint or kidney problems.
  • Patients at risk of uric acid kidney stones.

Allopurinol tablets may not be suitable for:

  • Anyone allergic to allopurinol or tablet ingredients.
  • People with a history of severe skin reactions to allopurinol.
  • Patients with severe kidney or liver disease without close monitoring.

If you are unsure, the online consultation allows one of our UK prescribers to review your medical history safely.

Possible Side Effects of Allopurinol Tablets

Like all medicines, Allopurinol tablets can cause a number of side effects, but not everyone experiences them.

Common Side Effects:

  • Skin rash
  • Nausea or vomiting
  • Diarrhoea
  • Mild stomach discomfort

Uncommon or Rare Side Effects:

  • Drowsiness or headache
  • Changes in liver function tests
  • Fever or general feeling of being unwell
  • Joint or muscle pain

Serious Side Effects (Seek Medical Help Immediately):

  • Severe skin reactions such as blistering or peeling
  • Sudden swelling of the face, lips, or throat
  • Signs of allergic reaction, such as difficulty breathing

Allopurinol tablets should be stopped immediately if a rash appears, as this can signal a serious reaction.

Possible Interactions with Allopurinol Tablets

Allopurinol tablets can interact with some medicines, which may increase side effects or change how treatment works.

Tell one of our UK prescribers if you use:

  • Blood-thinning medicines such as warfarin.
  • Immunosuppressant medicines.
  • Diuretics used for blood pressure.
  • Antibiotics such as amoxicillin.

  • Reduce uric acid at the source.
  • Prevent repeated gout attacks.
  • Protect joints from long-term damage.
  • Lower the risk of kidney stone formation.

Frequently Asked Questions

Allopurinol tablets can be used in people with kidney problems, but the dose is usually lower. One of our UK prescribers can adjust the dose carefully based on kidney function to keep treatment safe.

Yes, gout attacks can happen more often when you first start Allopurinol tablets. This happens because uric acid deposits begin to break down. This is temporary and does not mean the treatment is failing. Keep taking the tablets unless advised otherwise by our prescriber.

No, you should keep taking Allopurinol tablets during a gout attack unless one of our UK prescribers tells you to stop. Stopping suddenly can cause uric acid levels to rise again and trigger more attacks.

Alcohol increases uric acid levels and raises the risk of gout attacks. While taking Allopurinol tablets, limiting alcohol, especially beer and spirits, gives better long-term gout control.

Many people with chronic gout take Allopurinol tablets long-term to keep uric acid levels under control. Whether treatment is lifelong depends on your gout history, uric acid levels, and response to treatment, which our prescriber reviews regularly.

Yes, when taken every day as prescribed, Allopurinol tablets reduce uric acid levels and lower the risk of future gout flare-ups. They are used for prevention rather than treating sudden pain.

No, Allopurinol tablets do not treat sudden gout pain. They work in the background to reduce uric acid and prevent attacks over time. Pain relief medicines may be used separately during flare-ups if advised by our pharmacist or prescriber.

Stop taking Allopurinol tablets immediately and seek urgent medical advice. Skin rashes can be a sign of a serious reaction and must never be ignored.
