My mom was prescribed Xanax, Ambien, Citolopram, and Buspirone. I'm concerned about her. She sleeps all day. She is majorly overweight, and i believe she has sleep apnea but she has not been officially diagnosed with it. She is foaming at the mouth when she sleeps. She apparently is taking those medications because she has panic attacks and depression. Here are my questions, should all of those prescriptions be taken together? and should i be concerned about the foaming at the mouth?
