Did unprotected sex with lady of unknown status. After this I take alprasfe 0.25 mg regularly for better sleeping. I did my hiv1/2 and p24 combo test from drlal pathlabs after 3 months, 6 months, 9 months and after 355 days. All tests are non reactive. Is regularly taking of alprasafe 0.25 mg affects hiv antibody production. Is there any chance of false negative hiv test because of alprasafe 0.25 mg. Is alprasafe a immunosuppressive drug.
