Bayer - Cramp Relief Midol® Patch 3 per Box [3/CT]

Heating patches for period cramps and back pain relief are air activated. Each pain reliever heat patch provides targeted, therapeutic heat to relieve menstrual cramps and back pain for up to 8 hours. Patches are applied to lower abdomen or lower back on top of undergarments; not to skin. Thin pain relief patches are individually wrapped and discreet for on-the-go use. Heat therapy soothes pain and cramps associated with premenstrual syndrome (PMS) and your period by promoting blood flow, reducing muscle tension and relaxing muscles. There are six one-time-use patches in a box.
