Which is better to take levofloxacin or norfloxacin for enteritis is mainly based on the causative organisms, and there is no such thing as which one is better. If you need to use the drug, you need to use it under the guidance of your doctor. Levofloxacin is used to treat enteritis caused by sensitive gram-negative and gram-positive bacteria. Norfloxacin can be used for enteritis caused by sensitive bacteria such as aerobic gram-negative bacilli, Citrobacter spp, Enterobacter cloacae, and Enterobacter aerogenes. It needs to be judged according to the causative organisms that cause enteritis which drug is suitable for patients to use for treatment. Levofloxacin and norfloxacin are both fluoroquinolone drugs, so the therapeutic effect is not much different. Fluoroquinolone drugs are contraindicated for pregnant and lactating women, and patients under 18 years of age. They should be used with caution in patients with a history of tendon disease and myasthenia gravis. Adverse reactions such as dizziness, headache, diarrhea, nausea and abdominal pain are often experienced by patients after use. If you need to use the drug, you need to use it under the guidance of a doctor, do not use the drug at your own discretion.
