How long it takes to recover from drug-induced kidney injury cannot be generalized and needs to be judged according to the specific condition. If the injury is acute, it may recover to normal in days~months; if it is chronic, it may never recover. If the drug-induced renal injury is acute, it is necessary to stop the suspected drugs in time, and actively give the drug symptomatic supportive treatment to avoid drug damage in the process of treatment, through active and effective treatment, the acute renal injury can be returned to normal in a few days~months in general. If the drug-related kidney injury is chronic, that is, more than 3 months, the recovery time may be long, and anemia, hypertension and other symptoms may appear in the later stage, and with the development of the disease, it may progress to uremia. So, if the kidney injury is chronic, it is likely to never recover. Patients with drug-induced kidney injury are recommended to visit regular hospitals in time and standardize the treatment under the guidance of physicians.
