- Heat Vibes Menstrual Pain Relief Heat Patches - 6 Count Pack for Period Cramps and Backache

I have been using these Midol patches for over a year and cannot imagine going without them now. These discreet patches go right on the outside of your underwear and heat up fairly quickly, giving you all the benefit of a heat pad without the bulk. Best of all, they can't even be seen through leggings, giving you a bit of comfort during your workout or at work. I also love that the packages are small enough to fit in any size purse and last for eight hours, giving you the comfort you need when you need it. From my own experience, they last about six to seven hours of the eight-hour period. While they work longer, they start losing their effectiveness after this. The size is also perfect for going on my period underwear or normal panties. The heat is also the right amount of warmth, not burning but relieving pain. While they are a little expensive, they are worth it for stopping cramps during my time of the month.

Wish I would’ve known about this a lot sooner! I felt like I was dying with cramps. I put the patch on which stayed right in place! What shocked me the most was how it literally stays hot for 8 hours! It helped me so much that I ordered it for once a month on my subscribe and save. Highly recommend!!

Best pain relief for period cramps. I been using the heat pads when I have my period. At the beginning while I was at work and had cramps, but if I use them before I get cramps then I have very mild cramps to no cramps at all. Is so useful while at work or when you can't stay in bed with an electric heater pad.

Helps a lot and no skin irritation !!!

Good buy. Not the hottest but good since it's gentle on the skin.

This is the best thing that I’ve ever bought for my period. In 15 minutes the pain has gone away

So I got these originally at CVS and they worked great super warm/heat was amazing. Ordered these and seems like a bad batch. Not even warming or providing heat. I needed it for horrible pain I’m experiencing, super disappointing.

I purchased these for my teen daughter. She gets really awful cramps and I feel bad when they happen at school. I always send her with some midol she can take at school, but I know that heat is always a comfort for her. She tried these out and said they are amazing. She said even through PE class it stayed in place and didn't crumple, nothing. She said it stayed warm all day long at school. She said that it was really comforting for the cramps and helped eased the pain. She rarely ever asks me to buy anything and she texted me from school saying, "please buy more of these heat pads, they are awesome"
