If you are applying cephalosporin antibiotics or anti-inflammatory drugs such as metronidazole or nitimidazole, it is usually appropriate to drink alcohol about seven days after stopping the medication. In the case of other types of anti-inflammatory injections, it is generally appropriate to drink alcohol three days after stopping medication for three days. Some anti-inflammatory injections will produce a disulfiram-like reaction when they come into contact with alcohol, which can cause patients to experience symptoms such as facial flushing, conjunctival congestion, headache and dizziness. It will also cause a drop in blood pressure, accelerated heart rate, and in severe cases, shock and even death can occur. If you are using cephalosporins and nitroimidazoles, you should stop drinking for 7 days before drinking. However, if the patient applies macrolides, tetracyclines, aminoglycoside antibiotics, these drugs do not produce disulfiram-like reactions when exposed to alcohol after use. However, during the period of medication, drinking alcohol may induce or aggravate the adverse drug reactions, and also lead to liver and kidney function injury.

It is recommended to use the drug under the guidance of a doctor, pay attention to diet during the use of the drug, develop good habits, and avoid drinking alcohol.
