PKU Sick Day Tips: 

·        Treat the illness first. Put PKU on the back burner.

·        Appetite? If yes- then let them eat, if no-don’t force them.

·        Encourage fluids to keep hydrated, e.g. water, Pedialyte*, fruit juice, low protein gelatin, broth.

·        Formula? Yes, if tolerated (may use diluted or full strength).

·        Offer food when appetite returns-ease back to diet. It may take several days before full diet can be resumed.

·        Will blood phe level increase? Very likely a temporary increase may occur. But remember, treatment of illness needs to take priority. 

  *As of July 2000, all Pedialyte products, including flavored and freezer pops, no longer contain aspartame (Nutrasweet).
