Hi Nelson. I started Androgel therapy a while ago while I was using a cocktail that included Trizivir and other meds. I don't remember the specific meds involved. I had a difficult time with this cocktail. It caused rashes, itching, etc. I did not take the medicine as I should have because of these side effects. In fact, I took very little. However, the testosterone therapy went really well. Very muscular and very easy to lose body fat. I probably was below 10 %. Sadly, because of my poor adherence to the Trizivir cocktail, I became resistant to the meds and had to switch to my current cocktail which is Videx (reduced dose), Viread and Isentress. I am adherent to this regime..with tolerant side effects. However...the testosterone therapy is no longer working....no sex drive, increased body fat, loss of muscle tone. Complete loss of all the benefits I once had. The testosterone therapy worked with the first cocktail while having very little HIV meds in my system. Now...with "full dose" HIV meds in my system, the testosterone therapy is no longer working. It seems as though the meds are destroying the effects of the testosterone, probably both natural and artificial. Could this be the case? What can I do now to get back to the the way things were while on very little HIV meds? Thank you for your input.

You are now taking a combination that most doctors avoid prescribing. Videx (DDI) can interact negatively with Viread (tenofovir- TDF). Coadministration of DDI with tenofovir may increase the plasma concentrations and toxicity of didanosine (ddI)causing decreased creatinine clearance and pancreatitis. There is also stunned increase in CD4 cells and higher virologic failure.
A study concluded that switching to a HAART regimen containing ddI + TDF is associated with evolutive mitochondrial damage. This mitochondrial damage can affect muscle and fat mass, so that is why you see a change now in your body composition.
I hope your doctor can find another combo for you without DDI! Even at lower doses, that drug is toxic.
