I am trying to find out if any of my medications interact with one another. All I want to do is sleep and I have lost motivation to get out of bed. I take Lexapro 20 mg daily, Levothyroxine 200 mcg daily, Hydroxyzine 25 mg twice daily, Calcium 500 mg three times daily, Vitamin D 50,000 units weekly, Norco 7.5 mg three times daily, Zanaflex 4mg two tablets at bedtime, and Topamax 50mg twice a day.
