What is Allopurinol?

Allopurinol is a medicine use to lower uric acid levels in the body. It is mainly prescribed for people with gout or kidney stones caused by high uric acid. It is also use for some cancer treatments that increase uric acid levels.

How Does Allopurinol Work?

Allopurinol works by reducing the production of uric acid in the body. Too much uric acid can form crystals in the joints, causing pain and swelling (gout). By lowering uric acid, allopurinol helps prevent gout attacks and kidney stones.

How to Take Allopurinol

• Allopurinol is usually taken once a day with water.
• It is best to take it after food to reduce stomach upset.
• Drink plenty of water to help remove uric acid from the body.
• Do not stop taking it suddenly—it works best when used regularly.

Possible Side Effects

Like all medicines, allopurinol may have side effects. Some common ones include:

• Skin rash
• Stomach pain
• Nausea
• Diarrhea

In rare cases, it can cause severe allergic reactions. If you get a serious rash, swelling, or difficulty breathing, see a doctor immediately.

Important Things to Know

• Allopurinol is not for quick pain relief during a gout attack. It prevents attacks but does not treat sudden pain.
• Gout attacks may happen more often when starting allopurinol, but this improves over time.
• Avoid alcohol and high-purine foods (like red meat and seafood) to help control uric acid levels.

Conclusion

Allopurinol is a helpful medicine for people with gout or kidney stones caused by high uric acid. It works by lowering uric acid levels and preventing painful attacks. Always take it as prescribed and talk to your doctor if you have any concerns.
