My problem is fatigue an muscle weakness want to get off Norvasc. Is there a similar BP med I could mention to DR .I also have an issue with new med causing me low blood sodium Lisiniprol dropped my sodium down to 122 norm is 135-145. Was in ER. I'm taking fludrocortisone for the hyponatremia. The constant fatigue is causing depression. Tried wellbutrim. For depression. It also dropped my sodium level.
