I've heard grapefruit could interfere with some meds, but never anything about oranges or lemons. If you're concerned you can always check with your pharmacist.
Bipolar, panic disorder, PTSD, PCOS, hashimoto's disease/hypothyroidism, acid reflux, and in the process of being diagnosed with either crohns, colitis, or even lupus...who knows really! the docs sure don't lol. Too many meds to list!
