Testosterone looks like a tablet, but it sticks to your gum like a patch. To use the patch:
- Keep the patch in the blister pack until you are ready to use it. Do not use damaged blister packs.
- Put the flat side of the patch on your fingertip. Place the patch against your gum and to the left or right of your front teeth. Gently push the it up as high as it will go. Then push on the patch from the outside of your mouth for at least 30 seconds. The patch should stick to your gum.

- Each time you put in a new patch, put it on the side opposite from where you put the last one.
- Keep the patch in your mouth all the time, unless you are changing patches. Check to make sure the patch is still in place after you eat or drink, use mouthwash, or brush your teeth.
- To remove a patch, use your finger to gently loosen it. Then slide it down over your teeth and take it out.
- Use testosterone 2 times a day, once in the morning and once in the evening (about 12 hours apart), unless your doctor tells you differently.
