Reaction to adhesive and generalized itching?

Some patients can develop allergic reactions to the sterile strips. They usually presented with itching, redness and blisters. You should call your surgeon.

I would bet you had the adhesive Mastisol applied to the skin to help the Steri Strips stick, and that you had previously had Mastisol on another procedure (which sensitizes you to future reaction).  And I would also bet that the Steri Strips are not the culprit.  I see this in maybe 1 in 50 of patients that get Mastisol.  It is one reason I no longer put Mastisol on when I am re-applying Steri Strips in the office postoperatively.  If this is the case, the good news is the itchy, red, blistery rash will go away and ultimately have no effect on your scars (although occasionally a dark skinned person will have hyperpigmentation that will last for months).  The bad news is the rash can be as annoying as a bad case of poison ivy or poison oak.  I have found that topical hydrocortisone is worthless.  A five-day steroid taper (Medrol dosepak) is the best at relieving the symptoms.  Benadryl helps, but will make you drowsy.  The itchiness will take about a week to go away, but the steroid taper sure reduces the severity.
