Hi, Tomorrow morning, I have an appointment with my dentist to fill in my tooth, which is currently chipped. Is it alright to use xanax and/or adderall the night before? I have already consumed 1 mg of xanax tonight, but will not use any more xanax or adderall (I am prescribed both) if it can cause side effects with the local anasthetics i will be receiving tomorrow. I ask because previously, my dentists said that cocaine used within 24 hours of local anesthetic being applied to the tooth for a fill in can cause fatal reactions. Thanks, Coby
