Allopur (Allopurinol Tablet) 300 mg

Allopur is used to manage conditions related to elevated uric acid levels in the body. It acts on the metabolic pathway that produces uric acid, helping to prevent and treat the following conditions:

• Gout: Reduces the frequency and severity of gout attacks by lowering uric acid levels, which can form crystals in joints and tissues.
• Hyperuricemia: Treats high uric acid levels in the blood, which can lead to complications such as kidney stones and joint damage.
• Prevention of tumor lysis syndrome: Helps prevent the rapid breakdown of tumor cells that can release large amounts of uric acid into the bloodstream.

• Allopurinol works by inhibiting the enzyme xanthine oxidase, which is responsible for converting xanthine and hypoxanthine into uric acid. By blocking this enzyme, Allopurinol reduces the production of uric acid, thereby lowering its levels in the blood and urine. This helps to prevent the formation of uric acid crystals that can cause gout and other related conditions.

Allopur may cause various side effects, ranging from mild to severe. Common side effects include gastrointestinal discomfort and skin reactions, while serious or rare side effects can affect multiple organ systems.

Common Side Effects

• Nausea and vomiting

Allopur should be used with caution and under medical supervision. Important precautions include:

• Allergy: Do not use Allopur if you are allergic to allopurinol or any of its ingredients.
• Kidney or liver disease: Use with caution and under close medical supervision if you have kidney or liver problems.
• Dosage adjustment: Your doctor may start with a low dose and adjust it based on your response and medical condition.
• Hydration: Drink plenty of fluids to help prevent kidney stones and maintain adequate urine output.
• Diet: Avoid alcohol and foods high in purines, such as organ meats and certain seafood.

Allopur can interact with other medications, potentially altering their effects or increasing the risk of side effects. Major and moderate interactions should be carefully managed.

Major Interactions (Avoid)

• Azathioprine or mercaptopurine: Allopurinol can increase the levels of these medications, leading to increased toxicity.
• Didanosine: Allopurinol can increase the risk of didanosine-related side effects, such as pancreatitis.

Moderate Interactions (Monitor Closely)

• ACE inhibitors or diuretics: Increased risk of hypersensitivity reactions, especially in patients with kidney problems.
• Warfarin: Allopurinol may enhance the anticoagulant effects of warfarin, requiring close monitoring of blood clotting times.
