Are there any medicine that prevents HIV or AIDS?

Yes, there are medications that can help prevent HIV infection, most notably pre-exposure prophylaxis (PrEP), which is a daily pill taken by individuals at high risk of contracting HIV. Additionally, post-exposure prophylaxis (PEP) can be administered within 72 hours after potential exposure to HIV to reduce the risk of infection. While these medications are effective in preventing HIV, they do not cure HIV or AIDS. Regular testing and safe practices are essential for overall prevention.
