I keep finding information telling me about one company sold out to another company and then to another company. Who exactly is the manufacturing pharmaceutical company for Evamist Spray. My doctor wants me to start taking this for hot flashes, but it is really expensive and I want to see if the pharmaceutical company has an assistance program for low income patients. I hope to hear from you very soon, as I would like to start this medication right away. Thank you for your kindness in reading and answering this question.
