Tarceva related rash is possible.
In case of itchy rash you can try benadryl 25 mg tablets.
Also hydrocortisone ointment can be tried twice daily.
Both are over the counter.
In case of worsening like blister formation, rash in the mouth or genitalia should be taken seriously.
You need to go to the ER in that case.
Benadryl can be taken 2 tablets every 8 hours as needed.
