Consumers as well as some health professionals may not know that most medicine patches should never be cut before being applied to the skin. Patches are designed to give a constant amount of medicine over a certain period of time, which may range from several hours to a month. The medicine reaches your body by going through the blood vessels under your skin. If the patch is cut, the medicine in each half of the patch might be released too quickly, leading to a serious overdose.

Read Safety ArticleSome medicines are supplied in patches that you apply to your skin. The medicine reaches your body by going through the blood vessels in your skin. If you warm your skin, it gets red because the blood vessels widen. The wider your blood vessels are, the more medicine your body absorbs. Warming your skin with heating pads or with lots of physical activity can cause too much medicine in the patch to be absorbed. This is especially dangerous when using patches that relieve pain.
