How long before ferrous fumarate works

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective. Ask your doctor how much time to allow between your ferrous fumarate dose and other medicines you use, especially:.

Other drugs may affect ferrous fumarate, including prescription and over-the-counter medicines, vitamins, and herbal products.

Call your doctor for medical advice about side effects. Avoid eating foods that are high fiber at the same time you take your ferrous fumarate dose. High-fiber foods include whole grains, raw vegetables, and bran. Avoid milk or other dairy products for at least 2 hours before or 2 hours after you take ferrous fumarate.

Do not take any vitamin or mineral supplements that your doctor has not prescribed or recommended. Use Ferrous Fumarate Hemocyte exactly as directed on the label, or as prescribed by your doctor.

Do not use in larger or smaller amounts or for longer than recommended. You may need to follow a special diet while using ferrous fumarate. Follow all instructions of your doctor or dietitian. Learn about the foods to eat to make sure you get enough iron from both your diet and your medication. Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Iron is absorbed in the small intestine like most nutrients , specifically the duodenum.

But how long it takes for an iron tablet to be absorbed, depends largely on when and how you take it. In other words, iron will increase as soon as you start taking in more iron. How long it takes for iron to get into your system depends largely on 1 why they were low in the first place and 2 how far below normal they were. The lower your current level, the longer it will take to build up a sufficient amount of iron in your system.

You should still continue taking an iron supplement even when you reach optimal iron levels if you cannot get enough iron from your diet alone. Believe it or not, you can be taking an iron supplement daily and still not get the amount of iron you need — if your body is not absorbing it correctly.
