It is not allowed to drink alcohol when taking artificial oxymetholone metronidazole capsule. As a more commonly used antibiotic in dentistry, metronidazole has a good therapeutic effect on many bacterial infections in the oral cavity, especially for anaerobic bacterial infections, such as caries, periapical disease, periodontal disease, and many oral related diseases have a good anti-inflammatory and pain-relieving effect after applying metronidazole, so metronidazole is the first-line antibiotic commonly used in clinical dentistry. However, just like cephalosporin, most people now know that cephalosporin can react with alcohol, which we call disulfiram reaction, causing nausea, vomiting, palpitations and a series of symptoms, and serious disulfiram reaction can also cause death. Metronidazole, also a representative of the nitroimidazole class of drugs, can also react with alcohol in a disulfiram reaction. To avoid this serious side effect, patients should refrain from drinking alcohol for at least three days after taking metronidazole for oral infectious diseases. Patients must also be aware that there are many similar drugs called Dental Pain Relief, Periodontal Health, Dental Containment, etc., which are said to be for toothache treatment, but their main ingredient is metronidazole, which also has a risk of disulfiram reaction with alcohol, and must not be confused by its name.
