Depending on the individual’s physical condition and the duration of the condition and medication, the recovery time for drug resistance will be different. For example, cephalosporin resistance, some need about half a year, some stop the drug about a year to recover. Taking and using antibiotic treatment is usually no more than 7 days, using too long or stopping without authorization in the middle of the time, will produce drug resistance. Therefore, when undergoing antibiotic treatment, be sure to take or use it under your doctor’s supervision, and don’t take the medication on your own or stop it without authorization. If drug resistance occurs, you can go to the hospital to do drug sensitivity tests, and then use more sensitive drugs for treatment, which are usually more effective. In short, the recovery time after drug resistance is uncertain, you can consult your doctor for details.
