Allopurinol Tablets are recommended to be taken after meals. Allopurinol Tablets is a drug that inhibits the production of uric acid and is used clinically to treat gout and hyperuricemia. Allopurinol tablets can cause serious irritation to the gastrointestinal tract, mainly in the form of nausea, vomiting, abdominal pain and diarrhea. Therefore, to reduce the irritation of the gastrointestinal tract, it is recommended that allopurinol tablets be taken 30 minutes after a meal. Too little protein in food may cause the drug effect of allopurinol tablets to be too strong. Do not over-restrict protein intake during taking the drug. Also tea, coffee and alcohol can reduce the efficacy of allopurinol tablets, so do not drink tea, coffee, alcohol or beverages containing these ingredients while taking the medication.
