s important to notify your doc about it - depending on how high your fever is, they may ask you to remove the patch tmeporarily - for the same reason as avoiding other heat sources - too much medication can be released. When I was using the
patch (I had to stop it due to negative
side effects), one time I had a fever of 103.6 from strep throat and my doc had me remove the patch until my fever was below 100 (and use my BT meds during that time).
