How to use Crixivan
Take this medication by mouth with a full glass of water (8 ounces or 240 milliliters) on an empty stomach (at least 1 hour before or 2 hours after food) as directed by your doctor, usually 3 times daily. If upset stomach occurs, you may take it with other liquids (such as non-fat milk, apple juice, coffee, tea) or with a light meal (such as dry toast with jelly, corn flakes with non-fat milk and sugar). Avoid taking this medication with a meal high in calories, fat, and protein since this may decrease its effect. If you are directed to take ritonavir with this medication, take them both at the same times.
To help decrease the risk of kidney stones while taking indinavir, drink at least 6 full glasses (8 ounces or 240 milliliters each) of water or other liquids throughout the day.
