The last month my equilibrium started messing up. I've fallen twice from things spinning. I also passed out & fell head first last week on to a tile floor. I'm wondering if it could be a drug interaction? I'm taking 100mcg synthroid, 50mg presitiq, 300mg neurontin 2x daily, 40mg pravastatin, 15mg meloxicam, 50mg trazodone, imitrex as needed, xalatan eye drops, cosopt eye drops 2x daily,multi vitamins, fish oil & magnesium. I have fibromyagia, hypothyroidism, glaucoma, interstitial cystitis, migraines & 4 herniated disc. Could this equilibrium/veritgo be caused from a drug interaction?? The only drug that has changed in the last 3 month was an increase in my synthroid from 88mcg to 100mcg.
