I reduce my Norvir 200mg and Tripranavir 500mg to half!

Nov 17, 2011

After reading that many of the medication for HIV is tested in men who are at least 200lbs, I though that since I am a small guy 140lbs max, I could cut my Norvir to 100mg and Tripranavir to 250mg, taking one in the morning and one at night. I been doing this for two weeks now and my side effects are being gone since, no more soft stool ( almost every day dirrea), no more feeling tired, in fact I feel way better, with more energy. My question is; do you think that in a month I should check my blood to check any changes or if you know that this is just no a way that it will work, just let me know.

Response from Dr. McGowan

It is true that the "one size fits all" dosing may not hold true for all people. It is possible in some cases to get blood levels just before the next dose is taken (called the trough) is the best way to know the levels are adequate.

You must distinguish between the "main effects" of the drug and the "side effects". Taking no meds would also cause no side effects but it wold not benefit your HIV either. Of course the risk is that the blood level of the tipranavir would be too low. Since you are on tipranavir I assume your virus has some level of drug resistance which would require that the blood levels be maintained at a high level for suppression.

You should discuss this with your doctor, perhaps alternative regimens may be available that would be more tolerated and may not be compromised by taking an untested dose. You will definetley need to have your viral load monitored closely, breakthrough, if it were to occur, may not happen for several weeks.


something not well understood in the last question
