After taking the AIDS blocking medication, it is recommended to take an HIV antibody test one month, three months and six months after exposure. If you have a high risk of HIV infection, it is advisable to take HIV blocking medication as soon as possible, which can greatly reduce the chance of getting HIV, but oral HIV blocking medication cannot prevent HIV completely. After taking AIDS blocking medication, it is recommended to continue to test for AIDS antibodies, which should be repeated in one month, three months and half a year to rule out the possibility of infection. Usually, you should pay attention to cleanliness and avoid drug abuse, prostitution and high-risk behaviors that are easy to be infected by AIDS. Once the risky behavior occurs, it is recommended to go to a professional AIDS clinic for interruption and regular follow-up testing.
