Take ritonavir as directed with food. It is very important to take it regularly. If you often forget to take ritonavir, it may not work as well.
Take the tablets with a glass of water.
Measure the liquid carefully with an oral syringe or measuring spoon. Shake the bottle well before measuring each dose.
