How should I take ritonavir?

You should take ritonavir exactly as directed by your doctor. Typically, this will be twice a day. It's important to take ritonavir with food and to swallow the tablet whole. If you take the oral liquid, shake the bottle before opening and measure the dose accurately in a marked cup, oral dosing syringe or dose-measuring spoon. You can mix the liquid with a nutritional drink or chocolate milk to make it taste better.
