Yes, there are several precautions. Avoiding sports/exercise and hot showers just prior to and for 2 hours after each dose is important, since those activities increase the likelihood of developing an allergic reaction. If the dose is given in the evening, one should be awake for at least one hour prior to bedtime. For school age children, a good time to consume the daily peanut dose is once home from school, after eating a carbohydrate snack.
