I've been on 20 mg citalopram for over 15 years for depression and I'm on gabapentin for 3& 1/2 years for radiation induced neuropathy. I also occasionally have to take 5 mg Flexeril. I've also been on 1 mg Xanax at bedtime for many years and take .5 mg during the day for anxiety for the past 3& 1/2 years. In September my new psychiatrist prescribed 20 mg Cymbalta for my anxiety. I feel the Cymbalta has helped my depression and anxiety and I haven't had any issues with the combination of meds. The only thing I will say is that I now am more careful when I'm prescribed another new additional med in researching and making sure that the new med won't interact with any of the others. I hope you find some relief because I understand what a bear anxiety and health problems can be, feeding off of one another and snow balling.
