The recovery period for moderate depression generally takes more than 1 year if the patient receives scientific and regular treatment. Depression is a common clinical psychiatric disorder and has the possibility of clinical cure if it receives standardized staged treatment. At the beginning of moderate depression, it usually takes 1-3 months of medication to get significantly better; after that, in order to prevent relapse, it is necessary to continue taking medication for 3-6 months, which is called the consolidation period; finally, it enters the maintenance period, which lasts about half a year to one year. The whole course of treatment takes 1-2 years, and it is recommended that the medication should be used in full amount and duration during the treatment period. In order to prevent the development or deterioration of the disease, it is generally recommended to take medication regularly for more than 1 year, which can inhibit the development of the disease to a greater extent and prevent relapse. Since the relapse rate of depression within 2 years is over 60%, medication should not be stopped or reduced at will throughout the treatment period. Once a second relapse occurs, 3-5 years of maintenance medication is required, and if three relapses occur, lifelong low-dose medication is often required.
