Under normal circumstances, after taking ibuprofen pellets, it usually takes 2 hours before drinking alcohol. The half-life of ibuprofen in the body is usually 2-6 hours, so drinking alcohol after the release of the basic active ingredients of ibuprofen will allow the full absorption and digestion of ibuprofen in the body, and will not cause some reactions with alcohol such as alcoholic allergy or secondary allergy to ibuprofen, which will lead to secondary failure of the drug. The situation of secondary drug failure will arise. In addition, drinking alcohol after taking ibuprofen should only be allowed 2 hours after taking ibuprofen if the patient has no previous allergic reactions to alcohol or ibuprofen. If there is a history of previous allergies, it is usually recommended that alcohol should not be consumed after taking ibuprofen.
