The present invention is directed to kits and methods for the treatment of a patient suffering from post-traumatic stress disorder (PTSD) and/or hot flashes by an administration of a mixture produced by a combination of a long acting local anesthetic combined with clonidine. The combination of the two pharmaceuticals produces a significant increase in duration and speed of onset of sympathetic blockade, increased intensity of the sympathetic blockage as well as the reduction of local anesthetic absorption locally. The combination significantly improves the efficacy, speed of onset and block intensity of a right sided cervical sympathetic ganglion injection (RCSGI) leading to increased length of resolution of PTSD and hot flashes as well as reducing the potential for complications related to absorption of the local anesthetic.
