Although a variety of medications can treat schizophrenia, the method of use is not simply a matter of having the patient swallow a pill to achieve a therapeutic outcome, but rather has its own strict method of medication use. The most basic methods of use are as follows: First: A psychiatrist must select a drug that has a better therapeutic effect on the patient based on the patient’s specific condition, rather than any schizophrenic patient being cured by using any 1 of these drugs. Second: Treatment is best carried out under inpatient conditions; or in a strict outpatient setting where regular reviews can be adhered to; or in a home bed run by a psychiatrist. In short, treatment must be carried out under the supervision of a psychiatrist specializing in psychiatry. Third: All medications used to treat schizophrenia need to follow a strict course of treatment. Generally speaking, a course of treatment lasts 3-6 months. The duration of the course of treatment for each patient should be decided by the psychiatrist according to the patient’s illness and the specific circumstances of the treatment process. If the course of treatment is not enough, the efficacy will be affected; if the course of treatment is too long, it is also necessary to increase the side effects of drugs, which will bring some harm to patients. Therefore, the length of treatment, non-psychiatric professionals can not determine. Fourth: The principle of using any kind of drug is to start with a small dose, gradually increase it to a full therapeutic dose, and continue with the full therapeutic dose for a period of time before gradually reducing it to the most appropriate (to keep the condition stable and the drug side effects small) dose (maintenance dose), and then take it for a long time to consolidate the treatment. As for the speed of “gradual dosing”, the individual selection of the highest therapeutic dose, the duration of the highest dose, the speed of dose reduction, the size of the maintenance dose, etc., there are strict scientific and technical aspects to decide which small dose to start with and then gradually increase to the full therapeutic dose according to the patient’s overall condition, which should be mastered and decided by a psychiatrist. The decision should be made by a psychiatrist. Fifth: After a patient enters a course of treatment, the adverse effects of drugs must be closely observed. Sometimes it is necessary to decide to increase, decrease, combine, discontinue, or replace medications according to the patient’s treatment effect and the severity of side effects, which are also highly technical tasks that are difficult for non-psychiatric professionals to accomplish. In conclusion, medication for schizophrenia is complex, and in inpatient or outpatient psychiatric treatment, the patient’s treatment plan is generally developed by a senior physician with experience as an attending physician or higher, and the treating physician is not allowed to change it privately. During the entire treatment process, the patient’s systematic treatment is completed through systematic observation and implementation of the treatment plan by the treating physician, as well as a series of treatment procedures such as regular check-ups by the senior physician, adjustment of medication dosage and treatment measures, etc. Only by doing so can the patient obtain a more desirable outcome and avoid treatment setbacks, treatment failures and unexpected incidents of adverse drug side effects. As can be seen, the effective treatment of schizophrenia has a strict treatment procedure that is highly scientific and technical. Therefore, it must be carried out under the guidance of a psychiatric medical marshal
