I had to use tagaderm myself everytime. It didn't really inhibit the dosaging. My doctor has stopped using them unless his patient's med insurances allow for replacements every 48 hrs instead of 72 hrs. Everyone of his patients, myself included, complained the patches were dry after 48 hrs, and the last day was miserable as a result.
Seems the newer patches are of poor quality in a new of ways. Good luck!
