I have HIV infection, I do not have AIDS. my viral count is undectectable and I have been using the pil of sulfamethoxazole/ tmp 800- 160 mg every Monday, Wednesday and Friday in an oral form white large pill, it was prescribed for me by a doctor when It was found that I have HIV because it was told at the time (3 years ago) that it might inhibit any damage when I was given the prescription to control HIV, lately about one and half years ago a new medicament was given to me to replace the same ones I have been taking when I first started and the nee re placed medicament is called ATRIPLA which have the same ingredients of what I used to take in a form of three other medicaments which are now a part of one single tablet which I am taking called ATRIPLA. should I continue to use it or should I discontinued its use. My viral count is undetectable at every time a lab is taking a sample to the Laboratory.
