What should I do if I miss a dose of my medicine?

NEVER miss a dose!  If you miss, the blood levels of your medicine could fall below the level that is necessary for effectiveness.  Resistance to the drugs can develop rapidly, causing your viral load to go up and/or your CD4 (T-cell) count to drop.  Often this can lead to a change in your medication regimen, which may be more difficult to take and/or have side effects.  With each new medication change, it becomes harder to control the HIV virus.

However, if you do miss a dose of any medicine, take it as soon as possible and then take your next scheduled dose at its regular time.  If it is almost time for your next dose, do not take the missed dose.  Wait and take the next dose at its regular time. Do not double the next dose.
