What are the Side Effects of Allopurinol Sustained-Release Tablets?

Allopurinol Sustained-release Tablets are a common type of Western medicine. After administration, its effect is slowly released and continuously exerted. This drug is mainly used for hyperuricemia and has good therapeutic effects for both primary and secondary patients. However, side effects such as rash, itching, nausea, vomiting, and abdominal distension may occur after administration.

1. Side Effects of Allopurinol Sustained-release Tablets

Allopurinol has side effects. The most common side effects after administration are allergic reactions such as rash and itching, as well as gastrointestinal reactions such as nausea, vomiting, and abdominal distension. Some people may also experience dizziness and elevated transaminase levels after administration. Therefore, careful monitoring must be carried out during the medication process, and appropriate treatment should be given promptly in case of side effects. All drugs have side effects, and some may have more side effects than others, but the number of people experiencing side effects is very small. Patients should not refuse to use medication due to concerns about side effects.

2. Indications

Allopurinol Sustained-release Tablets are indicated for:

• Primary and secondary hyperuricemia, especially hyperuricemia caused by excessive uric acid production;
• Repeated or chronic gout;
• Tophi;
• Uric acid nephrolithiasis and/or uric acid nephropathy;
• Hyperuricemia with renal dysfunction.

3. Use in Children

There is no experience in the use of allopurinol sustained-release formulations in children. Since the dosage of this product (sustained-release tablets) is difficult to adjust accurately, it should only be used in children when the risk of the disease itself outweighs the risk of the drug and there are no safer alternatives. When used, the dosage should be adjusted at any time by the doctor based on the child's condition and the results of blood uric acid and urine uric acid tests to ensure the lowest dose that produces a satisfactory uric acid-lowering effect.
