Hello.: Hello. I really haven't seen any sleep specialists making responses in the last few months, so I will change the tag to psychiatry so that you may get more responses. Xanax (alprazolam) is a dangerous drug. Many providers have elected to stop prescribing the fast acting form. One can easily develop a dependence on it. There have been deaths due to people coming off it quickly. Even though it is sedating it can seriously alter your sleep architecture which will prove problematic in the long run. Have you considered medical acupuncture to assist with sleep? Frankly, I don't prescribe xanax (alprazolam) for insomnia and I try to steer clear of it for anxiety when possible. Read more

The dentist may use anesthetic such as 0.3ml lidocaine with 1:100, 000 epinephrine. Would this interact/ have problems with my heart or BP medication.

Little concern: Stress form the procedure, particularly if you were not numb, would cause your body to release more Epinephrine then what is in the local anesthetic. That said I do try to error on the side of caution depending on the heart condition by not using the maximum dose (approximately 8 full injections) and breaking up multiple procedures over several appointments.
