This medication is an iron supplement used to treat or prevent low blood levels of iron (e.g., for anemia or during pregnancy). Iron is an important mineral that the body needs to produce red blood cells and keep you in good health.
Follow all directions on the product package, or take as directed by your doctor. Do not take more than the recommended dosage. If you have any questions, ask your doctor or pharmacist.
Iron is best absorbed on an empty stomach (usually if taken 1 hour before or 2 hours after meals). If stomach upset occurs, you may take this medication with food. See the instructions below for the liquid drops for infants/children. Avoid taking antacids, dairy products, tea, or coffee within 2 hours before or after this medication because they will decrease its effectiveness.
Take tablets or capsules with a full glass of water (8 ounces or 240 milliliters) unless otherwise directed by your doctor. Do not lie down for 10 minutes after taking your tablet or capsule dose.
Swallow extended-release capsules whole. Do not crush or chew extended-release capsules or tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split extended-release tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
If you are taking chewable tablets, chew the medication thoroughly, then swallow.
If you are taking a liquid suspension form of this medication, shake the bottle well before each dose.

If you are giving the liquid drops to an infant or child, use the dropper provided to carefully measure the dose. The dose may be placed directly into the mouth (towards the back of the tongue) or it may be mixed in formula (not milk), fruit juice, cereal, or other food as directed to increase your child's acceptance. It is best to give this medication right after a meal. Follow the directions on the product package for the brand that you use.
