Ferrous Gluconate Tips from Pharmacists

  • Iron is better absorbed on an empty stomach. But if ferrous gluconate causes stomach upset, it may help to take it with food.

  • Taking iron with vitamin C improves its absorption.

  • Iron supplements can make your stool appear darker. This is not something to worry about. But you should call your doctor immediately if you notice blood in your stool.

  • If you are taking the liquid form of ferrous gluconate, mix it with water or juice to prevent staining of your teeth. However, do not mix it with milk or alcoholic beverages such as wine.

  • Read the labels of your dietary supplements. Many supplements contain iron, along with other nutrients. Taking multiple iron-containing products can result in an overdose.

  • The body’s iron needs change during pregnancy and lactation. Tell your healthcare professional if you are pregnant or breast-feeding. They will tell you the correct dose of iron to take.

  • Do not give ferrous gluconate tablets meant for adults to children. Your child’s healthcare provider can tell you the appropriate dose for your child.
