The amount of Prograf 0.5mg Capsule you take and how often you take it depends on the type of transplant you have, your body weight, and what other medicines you are taking. Follow your doctors instructions carefully. You should take it on an empty stomach, at least 1 hour before or 2 hours after a meal. Take this medicine regularly to get the maximum benefit and keep taking it, even if you feel well. If you stop taking it, you may increase the chances of rejecting your transplanted organ.
