Should I switch?
Jul 29, 2002
OR: DDIEC, 3TC, Abacavir, Tenofovir, Nevirapine..
My concern is the toxicity and potential side effects of the new combos. Is my viral load safe with my present regimen? Thank you Gary
Response from Dr. Boyle
Wow, you have a very aggressive doctor. While there is some data to say that getting to less than 50 copies/mL is important, I'm not sure that I would use such an aggressive tack for someone who is barely above that number and may be "blipping" or taking a little bit longer to get undetectable than the usual 6 months (which has also been shown in studies to occur). I tend to agree with your relucatance to switch regimens and I would recommend that you either stick with the current regimen with careful monitoring or that you add ritonavir to improve the pharmacokinetics of indinavir. While this may increase side effects (mostly gastrointestinal in nature, but also some increased risk of skin problems and kidney stones) and lipids, it also eliminates the indinavir meal restriction, makes it a twice-daily medication and increases its effectiveness. One study showed that adding ritonavir to indinavir resulted in more patients achieving a viral load <50, despite their not being able to get there on indinavir alone.
