Acute drug hepatitis can be recovered in about 1-2 months after drug withdrawal, while chronic drug hepatitis is slower to recover and may take 3 months to 3 years. The recovery time of drug-related hepatitis is closely related to the toxicity and dosage of metabolites, the body’s resistance, and whether it is rescued in time. The majority of acute drug-related liver damage has a good prognosis. If the patient’s resistance is strong and the drug and metabolite toxicity is weak, the majority of patients can recover in 1-2 months after discontinuing the drug and treating the liver damage with liver protection and enzyme reduction. If long-term drug use leads to chronic liver injury, or cholestasis, recovery time is longer, the prognosis is worse, generally need at least 3 months to recover, and even up to 3 years for long time. Patients with drug-related liver injury usually pay attention to diet and rest, minimize exercise, quit smoking and drinking, and minimize the application of drugs to avoid aggravating the burden on the liver.
