Reactions to Iron Supplements

Iron aids the body in the production of red blood cells, with a lack of iron contributing to feelings of exhaustion and a higher chance of infection. According to WebMD, infants, toddlers, teen girls, and women who are pregnant or at child bearing age most often need iron supplements. While there are many benefits of taking an iron supplement, there is also a chance for negative side effects. Before taking iron, talk to a health care provider.

Effects

• The use of iron supplements often leads to mild side effects such as constipation, diarrhea, nausea, vomiting and leg cramps. According to the Mayo Clinic, these side effects often go away in people who continue a supplement routine. Side effects such as chest pain, chills, dizziness, a fast heart beat, numbness or tingling, a skin rash and difficulty breathing are some of the more serious side effects of iron supplements.

Warning

• Iron overdose is a possibility and may prove fatal, notes WebMD. Symptoms of an iron overdose include diarrhea, vomiting, pale or blue-tinged skin and fingernails, stomach cramping and overall weakness. The signs of an overdose may not appear for over an hour. Iron overdose is a medical emergency and must be treated by a medical professional as soon as possible.

Considerations

• Iron supplements may also cause allergic reactions and interact with other drugs. Iron often reacts with foods such as dairy products, eggs, spinach, whole wheat products, tea and coffee, causing the iron to be less effective, according to the Mayo Clinic. Iron reacts well and provides the greatest absorption when taken alone with water or with juice.
