That's is the dose I took 6.8 mls, it requires a doctors script. you need to take Ferrous Sulfate Elixir as your doctor suggests for your wt and size. Iron tablet's taken may affect other organs, careful! The iron infusion beware, has side effects days later, may need epi pen. I still feel a little off balance too. Never double a dose, anything you take into your body, can affect your liver, thyroid, heart, kidneys etc. My labs are normal with my blood, but my thyroid is causing inflammation, wt. loss, I need lots of protein and to regulate my immune system. My thyroid antibodies are 379 normal is < 35. Note: I was a healthy good looking fe with no underlying conditions had not seen a doctor except for an exam for college.
