I'm all new to keeping patches on and have struggled with them for 3 days.  I was prescribed Mylan patches. I've had 3 come off in just one weekend! UGH!  Desperate times call for desperate measures so after reading all these posts this is what I've done and seems to be working, even with swimming and showering. It's worth a try if you're having trouble with patches too!

Do your best to keep the "layers" flat as you apply them.....it will make a huge difference in how well it stays on and in place.
Clean the area well with warm water (I put my patch to the left or right of my belly button). Let it air dry well or give it a shot with the cool setting on a hair dryer for about a minute.

Apply the patch.

Curad waterproof tape works very well for me (and I sweat a lot, have oily skin and it's 95 and VERY humid where I live) Apply the tape on all 4 sides of the pain patch.

Then I applied a piece of Tegraderm and taped the edges of that down on all 4 sides with Curad WP tape.

Lastly cut a piece of Glad FREEZER bag (not regualr food bag plastic) to overlap the other layers and tape on all 4 sides. Press down as hard as you can for a minute (if you use a hair dryer, use the low setting for a minute....it helps make the adhesive, on everything, stick a lot better and press hard on it again.

I applied this yesterday morning, have showered 3 times (using hot water and taking my good old time!) and spent 6 hours swimming in the pool. It hasn't budged or bunched up at all since I put it on Saturday afternoon and the patch and layers are bone dry~no water has gotten near the pain patch! (I am calling Mylan for some of those special patch covers but until they arrive this will work.  I am also going to pick up some sports tape that a very wise lady recommended to me! ;)

 I sure hope this helps someone~it's frustrating when you only have so many patches and they won't stay on!

Have a good evening!
