Precautions for Antidepressant Use in Elderly Patients

Medication must be individualized, and guidance by a specialist physician is an essential principle. Treatment should begin with a low dose, gradually increasing to the therapeutic dose; similarly, when discontinuing medication, the dose should be tapered gradually to avoid withdrawal reactions.In elderly patients, reduced hepatic and renal function leads to slower drug metabolism; therefore, lower drug dosages are generally required.

Elderly patients have diminished tolerance to adverse drug reactions; thus, drugs with minimal adverse effects should be prioritized whenever possible. Elderly patients frequently suffer from comorbid physical conditions—such as Parkinson’s disease, cardiovascular disease, hypertension, diabetes, and glaucoma—requiring comprehensive consideration during treatment planning. Potential drug–drug interactions must also be carefully evaluated. Adequate treatment duration is crucial, and maintenance therapy must be sustained for a relatively longer period.
