How long does it usually take to recover from drug-related kidney damage is related to many factors such as the cause of the disease and the condition. In case of acute kidney damage, with timely treatment, the rapid recovery period may be 6~8 weeks, while the slow recovery period needs several months or even one year; in case of chronic kidney damage, irreversible chronic kidney disease may occur, and at this time, it is impossible to recover. 1. Acute kidney injury: after removing the drugs causing acute kidney injury as early as possible and taking active treatment, if the drugs are stopped and the treatment is timely, the rapid recovery period may be 6~8 weeks, while the slow recovery period takes months or even a year; if the treatment is not timely, different degrees of kidney injury may remain, or even progress to end-stage renal failure. 2. Chronic kidney injury: if the drug-induced kidney injury is not recovered for a long time, more than 3 months, it may evolve into chronic kidney injury, which may lead to tubular, interstitial and even glomerular injury, and if the patient has irreversible chronic kidney injury, he/she may not recover. If patients have drug-related kidney injury, it is recommended to go to regular hospitals in time and standardize the treatment under the guidance of doctors.
