A dose of 50 mg, every alternate day, is safe and effective for such patients. Patients should never stop using this medicine suddenly. They should reduce the dose gradually to minimize withdrawal symptoms. If patients suffer from intolerable symptoms even after reducing the dose gradually, they should resume the previous dose for a few days. Once the withdrawal symptoms subside, they should again start lowering the dose, but more gradually.
