Hot weather and transdermal patches
In this hot weather, if you use any form of prescription transdermal patch (e.g., pain relief or contraceptive, or HRT), it’s important to keep the area cool.
Elevated temperatures can cause the patch to release too much medication over a quicker period of time, so it’s important to keep it out of direct heat, and watch for any side effects.
If you’re concerned, please seek medical advice.
