For HIV-positive patients, early detection and treatment are advocated, and highly effective antiretroviral therapy needs to be initiated as soon as the diagnosis is clear. Prior to treatment, the patient’s general physical condition, the presence of opportunistic infections, and the presence of contraindications to certain antiviral drugs should be clarified. After the above-mentioned etiology is clarified, secondly, antiviral therapy needs to be given as soon as possible. Antiviral drugs commonly used today include zidovudine, lamivudine, mifepristin, nevirapine, abacavir, and klebsiella, among others. Usually two nucleoside drugs are used in combination with a non-nucleoside drug for the purpose of effective control of the virus in the patient’s body and to reduce the occurrence of drug resistance. It is necessary to take the medication regularly as prescribed by the doctor to avoid the occurrence of patients stopping the medication on their own.
