Hello, I take rxs: metoprolol, zetia and Lipitor. I also take fish oil, calcium, magnesium, zinc, vit D, unisom, melatonin, ranitidine, aspirin 325mg daily - most PCP request. I have Proventil inhalers as needed, Advair discus as needed and use Claritin D 24 hr as needed. I would like to try Instaflex. Is it OK with my med list. Metorpolol was recently added late December for atrial fib with rapid ventricular response - only had 1 episode which lasted est. 1 hour. Thank you.
