Date sent to the fda: 12/05/2016.(b)(4).Additional information was requested and the following was obtained from the doctor: it was reported within the additional information received on 11/09/2016, that there were pictures of the reaction.Please provide any available photographs of the patient reaction.Was any testing performed for allergies and results? what was the location of the blister reaction in relation to prineo? if you¿re asking for more pictures.No dice there aren¿t anymore.It doesn¿t matter as the wound is very well healed.She wants to have allergy testing done.She would like to know what the adhesive is on the mesh.I looked at the material that you sent.I did not spend long looking at it, but with a cursory glance it did not appear that the type of adhesive was listed on it.The whole point was to find out what substance should she be allergy tested for.But if that is proprietary, then you are of no help to my patient.The blister reaction was directly underneath the prineo mesh.The patient is allergic to tape.She is under the impression that most tape adhesives are made from pine derivatives.And she states that she is very allergic to pine.
