Peanut Allergy Patch

Is there a Skin Patch for Peanut Allergies? Wouldn't that be grand. Something like a medicine skin patch for sea sickness. It is not so far fetched as you might think.


The good news is that two French pediatricians have developed a skin patch for peanut allergy.
Dr. Pierre-Henri Benhamou told the Daily Mail: "We envisage that the patch would be worn daily for several years and would slowly reduce the severity of accidental exposure to peanuts. " 'The beauty of the patch is that it is absorbed just under the skin and is taken up by the immune system."
"But because it doesn't go directly into the bloodstream there is no risk of a severe reaction.”

The doctor also stated he and his colleague have already conducted a few safety trials. Their next steps will be to conduct trials to establish the size of the dose needed and the amount of time the patch would need to be worn. Read more at Mail Online

In June 2010, the U.S. Food and Drug Administration approved an application that allowed DBV Technologies, a private French company that specializes in food allergies, to begin conducting clinical trials on a new “Peanut patch” called Viaskin. 
Researchers at National Jewish Health are also testing the peanut patch with hopes that clinical trials will commence.


The peanut patch would work in a similar way to the Oral Immunotherapy treatment (OIT) used to desensitize my son Alexander to his peanut allergy. 
Yes my son is desensitized and doing well.  
His entire treatment journey is explained in detail on my blog Just A Little Peanut.

How does a medicine skin patch work? 
A patch is placed on your skin like a bandaid. The patch contains medicine which is slowly absorbed through the skin. How convenient!
The peanut patch slowly releases minute doses of peanut oil under the skin. The amounts are increased over time to hopefully desensitize the patient the allergy.

Alexander my peanut allergy teen recently used a medicine patch on his knee, prescribed by his phyical therapist.
An increasing number of medicines are now available in the convenient form of a patch. Medicine patches are currently being used to treat the following ailments:
Anti-inflammatories. Pain, Nicotine, Hormone Replacement Therapy, Anti-depressants, Sea Sickness, Alzheimers, Parkinsons (and many more).


If the peanut patch clinical trials prove safe and viable, it is unknown how long it will take before the patch is available for patients. I suspect this type of immunotherapy might be the wave of the future.
