To avoid staining, dilute with water or juice, and sip through a straw. Do not mix liquid iron supplements with milk. Iron stains can be removed from the teeth by brushing them with baking soda or hydrogen peroxide. Liquid iron supplements can also darken the gums of infants. To avoid this, place the dose well in back of the mouth on the tongue.
Iron supplements can interact with a number of medications.
If you take other medications, besides an iron supplement, ask your pharmacist for advice about drug interactions. Skip the missed dose. Take your next scheduled dose of iron on time. Do not double a dose of iron. Make sure your health care provider knows you are taking an iron supplement if you are being evaluated for stomach ulcers.
