When protease is blocked, or inhibited, HIV makes copies of itself that can't infect new cells. Protease inhibitors are almost always used in combination with at least two other anti-HIV drugs. Take Crixivan with water either 1 hour before or 2 hours after eating. Crixivan is best taken when your stomach is empty. You can check food nutrition labels for this information, but make sure the food item meets ALL of the above guidelines.
Examples are dry toast with jelly or cornflakes with skim milk.
You can take Crixivan with a drink of skim milk, coffee, tea or any juice apart from grapefruit juice. Grapefruit juice stops your body absorbing Crixivan. Drink lots of water when taking Crixivan to avoid kidney stones - at least 8 glasses of water every day. Don't skip doses. Skipping doses gives the HIV in your body a chance to get resistant which means the Crixivan won't work.
