My mother is 70, about 150 pounds and takes zolpidem tartrate 10mg, lexapro 20mg, hydrocodone, verapamil 240 mg, warfarin sodium 2.5 mg every day. She had a pulmonary embolism 8 years ago but survived with the implantation of a Greenfield filer in her left leg and the addition of warfarin to her daily routine. She often complains of chest pains, feels dizzy, and will have fainting spells from time to time. She also has been diagnosed with Neurally mediated syncope. (She hates to drink water which I suggested to her many times so dehydration may be an issue as well.) I worry about her a lot and want to do all I can to make sure that her medication is helping rather than harming her. Any response will be helpful. Thank you.
