Before psychotropic medication is administered, the patient must first be thoroughly examined, and the condition of his or her illness, physical fitness, and the functional status of other organs and systems must be carefully assessed before choosing the appropriate medication. As far as possible, a drug with good therapeutic effect on the patient and little adverse reaction should be chosen, and adequate therapeutic dose and sufficient treatment time should be given. Frequent change of drugs, arbitrary change of dosage and inappropriate combination of multiple drugs should be avoided. The use of drugs must have clear goals and indications. Appropriate drugs should be selected according to the characteristics of symptoms in order to achieve the expected results. Discontinuation of psychotropic drugs should be decided according to the condition, efficacy, adverse reactions and other factors. Discontinuing medication prematurely may lead to relapse, and using medication for too long will increase the financial burden of the family and the adverse effects of medication. For patients with long-lasting and stable conditions, the dosage should be gradually reduced to complete cessation of medication, and abrupt cessation of medication is contraindicated, especially for anti-convulsant drugs.
