bonez3861, I was being given to much Thyroid Medicine (Methimazole 5 mg) for Hyper thyroidsim and it would bottom out my blood pressure and make me dizzy. They lowered the dosage and my thyroid levels are great. I have never been able to tolerate any of the meds for Hypothyroidism (I have both Thyroid diseases). I would talk to your Endocrinologist about the thyroid medication. Blessings & Happy Thanksgiving.
