Let's take a minute to talk about your medication.  

This is Synera. It helps to prevent pain from small medical skin procedures. It may have other uses, too. 

Synera is a patch. It contains two different numbing medicines to help prevent pain. It is applied to the area of skin 20-30 minutes prior to the procedure. You should use it exactly as your doctor tells you to. For the safety of yourself and others, you should read the full instructions for applying, removing, disposing, and storing patches. 

Most people tolerate this medicine well. The most common side effect is a reaction at the patch site. This might include an unusual sensation, swelling, and your skin turning red or pale. These effects are normal if they are mild and should go away shortly after the patch is removed. If these or other side effects become reasons you want to stop taking this medicine, please talk to your doctor or pharmacist. 

As with any medicine, rare but serious side effects could occur. You should read the Patient Information Sheet to know which symptoms to watch for and when to report changes. 
Women should check with their doctors before using this medicine while pregnant or breastfeeding.

Synera can interact with other medicines. You should always check with your doctor or pharmacist before taking or using other medicines. 

For best results with Synera, let your doctor know if you don't get the relief you were expecting, and ask your pharmacist if you have questions.
