SYNERA is a patch containing two different anesthetic (numbing) medicines – lidocaine and tetracaine – that is placed on unbroken, healthy skin, in the area where the blood draw, IV infusion, or injection site will be done. In just 20-30 minutes, SYNERA delivers two topical anesthetics to help prevent needle-stick pain. The patch is applied to skin (like an adhesive bandage) at the predetermined site. SYNERA uses a gentle warming technology that’s proven to better deliver the pain-reducing medication into the skin. It slightly increases the temperature of the skin, increasing blood flow to the area and speeding up delivery of the numbing medications. After 20-30 minutes, the patch is removed, and the area under it will be numb. The area is then gently cleaned to prepare for the needle stick.
