Xanax for Juvederm Lip Injection with out a Nerve Block?

It is uncommon to experience so much discomfort during an lip augmentation injection. Xanax may alleviate your anxiety, but is unlikely to have much effect on your perception of pain. Consider discussing with your doctor other available options such as topical or local anesthesia. Good luck.

If you are having that much pain, the Xanax may make you feel less anxious but you'll still have pain.  Topical anesthetic gel helps significantly.  If that is not enough, ask the doctor to do a nerve block and that will make it so much less painful.  Granted, it will feel for an hour or so as if you were at the dentist, but that's the price to pay for comfort.
 

Experienced injectors will use nerve blocks for filler injections - especially to a particularly sensitive area such as the lips.  The newest form of Juvederm also comes with lidocaine (a numbing medicine) incorporated into the product.  If used correctly, Juvederm injections to the lips should not cause very much discomfort at all.  Don't assume that just because your provider is a PS that he/she has extensive experience using injectables.  Always ask how many injections the providers (including the MDs) at the clinic have performed.  There is no substitute for experience.
