Antibiotics commonly used in the treatment of enteritis include quinolones, cephalosporins, sulfonamides and other antibiotics, but not for all patients with enteritis, such as viral infections do not need to use antibiotic treatment, the specific use of medication must follow the doctor’s instructions. 1. Quinolone antibiotics: such as norfloxacin, levofloxacin, etc., applicable to the treatment of most bacterial enteritis. This kind of drug is prohibited for people who are allergic to quinolones, and nausea, headache and other adverse reactions may occur in the process of using the drug. 2. Cephalosporin antibiotics: such as cefixime, ceftazidime (injectable), etc., mainly used for mixed infections or drug-resistant bacteria caused by severe infections in patients with enteritis. These drugs are contraindicated in people who are allergic to cephalosporins, and adverse reactions include diarrhea and rash. 3. Sulfonamide antibiotics: such as sulfasalazine, sulfamethoxazole, etc., mostly used in the treatment of chronic enteritis. This kind of drug is prohibited for those who are allergic to sulfonamides, and some of the drugs are also prohibited for children under 2 years old, pregnant and lactating women, and the adverse reactions include headache, allergic reactions, and so on. However, it should be noted that not all patients with enteritis can be treated with antibiotics, and antibiotics are not indicated for enteritis not caused by bacterial or fungal infections. Therefore, patients with enteritis must be guided by their doctors in the choice of medication and other treatment methods, and must not blindly dispose of them on their own to avoid adverse consequences.
