HIV/AIDS, anxiety
Hello Doctor, I had unprotected sexual intercourse (vaginal sex) with a female sex worker in mid-February.
I took PrEP (Tenofovir/Emtricitabine) approximately 25 hours later.
It has been 28 days since I took the medication, but I am still feeling very anxious and fearful.
I keep searching online for related symptoms, and any discomfort in my muscles or chest makes me unconsciously think I might have HIV.
Doctor, am I experiencing HIV anxiety, or is there a possibility of acute HIV infection? Can I confirm that I am not infected after testing at 2 weeks and 6 weeks post-exposure? Is it true that taking PrEP consistently provides over 90% protection? Thank you for your response.

Hello: Please discuss with the prescribing physician, as doctors in general outpatient settings are more specialized in HIV prevention.
Wishing you good health.

More Info
It's understandable to feel anxious after having unprotected sex, especially with a sex worker, as it raises concerns about sexually transmitted infections (STIs), including HIV. Your experience of anxiety and physical discomfort, such as muscle pain or chest tightness, can be quite common in such situations. This anxiety can sometimes lead to what is referred to as "HIV anxiety" or "HIV phobia," where individuals become preoccupied with the fear of having contracted HIV despite negative test results.
Regarding your specific situation, taking PrEP (pre-exposure prophylaxis) like Tenofovir (often referred to as "Gilead" in some contexts) within 24 hours after potential exposure is a proactive step. PrEP is highly effective in reducing the risk of HIV infection when taken as prescribed. Studies have shown that when taken consistently, PrEP can reduce the risk of getting HIV from sex by more than 90%. However, it is essential to adhere to the medication regimen and follow up with regular testing.
You mentioned that you took the medication and are concerned about the possibility of acute HIV infection. The window period for HIV testing can vary based on the type of test used. For most modern tests, including the fourth-generation tests that detect both HIV antibodies and antigens, you can typically get reliable results around 2-4 weeks after exposure. Since you have already tested at 2 weeks and 6 weeks post-exposure, if both tests were negative, it is a good indication that you are likely not infected. However, it is still advisable to follow up with another test at the 3-month mark for conclusive results, as some individuals may take longer to develop detectable levels of the virus.
Your physical symptoms, such as muscle discomfort and anxiety, may not necessarily indicate HIV infection. These symptoms can arise from various factors, including stress, anxiety, or other non-HIV-related health issues. It's crucial to manage your anxiety and seek support if needed. Consider discussing your feelings with a healthcare provider or a mental health professional who can help you cope with the anxiety surrounding your situation.
In summary, while your concerns are valid, the combination of timely PrEP usage and negative test results significantly reduces the likelihood of HIV infection. Continue to monitor your health, follow up with your healthcare provider, and consider counseling or support groups to address your anxiety. Remember, maintaining open communication with your healthcare provider is key to managing both your physical and mental health.
