1 ORAL FOOD CHALLENGE CONSENT Date Time I give my cnsent and authrize Dr. t perfrm an ral fd challenge t the fllwing fd:. What is an Oral Fd Challenge? If allergy test results and medical histry d nt shw fr certain whether r nt yur child has a fd allergy t a specific fd, we recmmend that yur child have an ral fd challenge test. The ral fd challenge invlves eating a serving f the allergic fd in a slw, graded fashin under medical supervisin. The fd challenge prcedure is the mst accurate test t determine whether a fd needs t be avided r will n lnger need t be avided. The fd challenge is undertaken when yur child is in generally gd health and can discntinue antihistamines fr a brief perid (usually 3-10 days) befre the test. What will happen during the Oral Fd Challenge? During the fd challenge, yur child will be given very small amunts f the specific fd being tested. If tlerated, increasing amunts f the challenge fd will be given with clse bservatin at each stage. Yur child will be bserved fr symptms such as itching, rash, abdminal pain, r difficulty breathing. If any symptms develp, yur child will be treated immediately. In mst cases, this will invlve the use f Benadryl r epinephrine t prevent any allergic reactins frm getting wrse. In studies f fd challenges, many children develp mild symptms during a fd challenge that require these treatments. Very rarely, ther treatments are needed fr mre serius reactins. What are the risks r discmfrts f an Oral Fd Challenge? The discmfrts assciated with the fd challenge are generally n mre than thse encuntered when eating the fd. Symptms usually are shrt-lived (less than 2 hurs). Symptms may include an itchy skin rash, nausea, abdminal discmfrt, vmiting, diarrhea, stuffy runny nse, sneezing, r wheezing. The majr risks invlved include severe breathing difficulties and rarely a drp in bld pressure. While a severe utcme such as death is theretically pssible, this has nt ccurred frm medically supervised ral fd challenges. The risk f a reactin is reduced by starting the challenge with very small amunts f fd, administering the fd ver a prlnged time perid and stpping the challenge at the first sign f a reactin, and by nt giving any fd suspected t cause a majr reactin.

2 Medicatins, persnnel and equipment will be immediately available t treat allergic reactins shuld they ccur. What are the alternatives t an Oral Fd Challenge? If yu chse nt t have the ral fd challenge, the safest thing t d is t cmpletely restrict the fd in questin frm yur child s diet. The nature and purpse f the Oral Fd Challenge, the risks invlved and the alternatives have been explained t me and all f my questins, if any, have been answered t my satisfactin. I acknwledge that the practice f medicine is nt an exact science and I acknwledge that n guarantee has been made as t the results that may be btained.
