Schizophrenia has a high relapse rate, and the more relapses there are, the more severe the mental deficit caused by the disease and the longer it takes to take medication to maintain treatment, which places a huge burden on the patient, family and society. Therefore, once you have schizophrenia, you should take measures to prevent relapse by all means. 1. Adhering to maintenance medication is the most effective relapse prevention measure. Most relapses of schizophrenia are associated with self-medication discontinuation. The relapse rate for those who cannot adhere to their medication is as high as 80%. Therefore, patients and family members should attach great importance to medication maintenance. Some patients who are discharged from the hospital think that “they are well, so they don’t need to take medication anymore” or “it’s too uncomfortable to take medication” and then stop taking medication and relapse soon after. It is important to note that discontinuation of medication by the patient often indicates fluctuation of the disease and is a precursor of relapse. When this happens, the patient must be convinced to take the medication to prevent a relapse. If the patient can not listen, then you should try to take the patient to the hospital for review or re-hospitalization. 2. Timely detection of the aura of relapse and timely treatment. Schizophrenia relapse has aura, as long as timely detection, timely adjustment of drugs and doses, generally can prevent relapse. Common relapse aura are: the patient has no reason to appear bad sleep, lazy, reluctant to get up, dazed and froze, emotional instability, unexplained temper tantrums, etc.. This is the time to seek medical attention and adjust the treatment. 3.Adhere to regular outpatient review. After the patient is discharged from the hospital, it is important to insist on regular outpatient review, so that the doctor can understand the condition dynamically, so that the patient is often under the medical supervision of the psychiatrist, and adjust the treatment plan according to the changes in the condition in a timely manner. The review also enables the patient to receive timely counseling and psychotherapy, relieving the patient of various confusions in the course of life, work and drug treatment. This also plays an important role in preventing relapse of schizophrenia. 4, reduce triggering factors. Family members and people around them should fully recognize the weakness of the mental state of schizophrenia patients after the disease and help them arrange for their life, work and study after discharge from the hospital. Talk to the patient often, help the patient to treat real life correctly, help the patient to improve psychological tolerance, encourage the patient to increase confidence, and guide the patient to enrich their lives.
