I m a female almost 70yrs old I take levothyroxine 0.088 MG and was on omeprazole 40MG for years the Doctor took me off from the last 2 months ago the first was Famotidine 20 MG twice a day that didn t work at all so he change it to Ranitidine 150 MG twice a day plus 20Mg of Omeprazole every three days. I still get heart burn on the days that I don t take the Omeprazole plus I m getting dizzy spells that I figured were part of my thyroid and/or being in the sun and/or allergies but now I wonder if it is the medication
