Iron supplements, such as Ferrous Sulfate (Iron 0), work by replenishing the body's iron stores and correcting iron deficiency. The mechanism of action involves the absorption and utilization of iron by the body. When ingested, iron is released from the supplement in the stomach and small intestine, where it is reduced to its ferrous form (Fe2+). This ferrous iron can then be absorbed by the intestinal cells, primarily in the duodenum and upper jejunum. Once absorbed, iron is transported through the bloodstream, primarily bound to transferrin, a transport protein. It is then delivered to various tissues, especially the bone marrow, where it is utilized for the synthesis of hemoglobin, the oxygen-carrying component of red blood cells. Iron is also essential for the proper functioning of enzymes involved in energy production and DNA synthesis, supporting overall cellular metabolism and growth. The mechanism of action of Iron 0 focuses on restoring iron levels, enhancing hemoglobin production, and improving oxygen transport capacity in individuals with iron deficiency anemia.

The following are the uses of Iron 0:

• Used for manufacturing steel, which is an essential material for construction, infrastructure, and various industries.
• Used for producing cast iron, which is used in pipes, automotive parts, and cooking utensils.
• Used for creating durable machinery and equipment, ensuring long-lasting performance.
• Used for transportation, as it is a key component in vehicles, railways, and shipping.
• Used for energy generation, with applications in wind turbines and electric motors.
• Used for household appliances and electronics, providing strength and functionality.
• Used for water treatment and distribution systems, ensuring clean and safe water supply.
• Used for surgical implants and medical equipment due to its biocompatibility.

In the case of an overdose of iron, the primary concern is the potential damage to the gastrointestinal system. Symptoms may include nausea, vomiting, and stomach pain. Overdoses can lead to liver damage and, in severe cases, liver failure. Prompt medical intervention is necessary to prevent further complications. Treatment involves managing the symptoms and preventing the absorption of further iron. It is crucial to seek medical advice if an overdose is suspected.

In the case of a missed dose of Iron 0, it is generally recommended to take the missed dose as soon as you remember. However, if it is almost time for your next scheduled dose, it is best to skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for a missed one. If you miss multiple doses, contact your healthcare provider for guidance on how to safely resume your medication regimen. It's important to maintain consistency in taking your medication as prescribed for optimal therapeutic benefits.

To take Iron 0, swallow the tablet whole with a full glass of water on an empty stomach, preferably in the morning, at least 1 hour before or 2 hours after a meal, as directed by your healthcare professional.

Following are the conditions/situations when Iron should not be used or administered:

• Allergy Should not be given to individuals with a known allergy to Iron or any iron-containing products.
• Hemochromatosis Contraindicated in people with hemochromatosis, a condition where the body absorbs and stores too much iron.
• Hemolytic Anemia Not suitable for patients with hemolytic anemia, as it can exacerbate iron overload.
• Iron Overload Should not be used in individuals with iron overload syndromes or those who have received multiple blood transfusions.
• Liver Disease Not recommended for patients with liver diseases that affect iron metabolism.
• Infections Should not be used in active infections as it can promote the growth of certain bacteria.
• Inflammatory Bowel Disease (IBD) Contraindicated during flare-ups of IBD, such as Crohn's disease or ulcerative colitis.
• Stomach Ulcers Not suitable for people with stomach or duodenal ulcers.
• Kidney Disease Should be avoided in patients with severe kidney disease.
• Before Blood Transfusions Iron supplements should be stopped before receiving blood transfusions.
• Certain Blood Disorders Should not be used in individuals with thalassemia or sideroblastic anemia without medical supervision.
• Children Iron supplements should not be given to children without a proper diagnosis of iron deficiency.

The side effects of Iron 0 may include:

• Constipation
• Darkened stools
• Abdominal pain or discomfort
• Nausea and vomiting
• Diarrhea
• Heartburn
• Temporary staining of teeth (when taking liquid forms)
• Skin discoloration

Following are the precautions and warnings:

• Iron supplements should not be taken by individuals with a known allergy or hypersensitivity to iron or any of the excipients in the formulation.
• Long-term use of iron supplements should be monitored by a healthcare professional, especially in cases of chronic iron deficiency, as excessive iron intake can lead to organ damage.
• Patients with gastrointestinal disorders, such as inflammatory bowel disease or ulcers, should use iron supplements with caution as they may exacerbate these conditions.
• Iron supplements may cause constipation, so it is advisable to increase fluid intake and consume fiber-rich foods to alleviate this side effect.
• Do not take iron supplements with tea, coffee, or dairy products, as they can reduce iron absorption.
• This medication should be kept out of reach of children as accidental overdose can be dangerous.
• If you are pregnant or breastfeeding, consult your doctor before taking iron supplements to ensure the appropriate dosage and monitor for any potential side effects.
• Patients with a history of liver disease should be closely monitored while taking iron supplements, as high doses may affect liver function.

Following are the drug interactions for Iron:

• Iron may decrease the absorption of other medications like Tetracyclines, Levodopa, and Bisphosphonates, so it is advisable to take these medications at different times.
• Iron supplements can reduce the effectiveness of Levothyroxine, a thyroid medication, and should be taken at least 4 hours apart.
• Antacids containing calcium, magnesium, or aluminum can decrease iron absorption, and should be taken at separate times.
• Iron can decrease the absorption of certain antibiotics, such as Ciprofloxacin and Levofloxacin, and may require a gap of several hours between doses.
• The absorption of Iron can be reduced by Cholestyramine, a bile acid sequestrant, and they should be taken at different times.
• Iron may decrease the effectiveness of certain medications used for Parkinson's disease, such as Levodopa/Carbidopa, and should be taken separately.
• Some medications used for heartburn, like Proton pump inhibitors (PPIs), can affect iron absorption and should be taken at different times.

Following are the food interactions for Iron supplements:

• Vitamin C-rich foods like citrus fruits, strawberries, and bell peppers can enhance iron absorption, especially non-heme iron from plant-based sources.
• Consuming iron-rich foods with foods high in calcium, such as dairy products, may decrease iron absorption. It is best to consume calcium-rich foods at a different time.
• Eggs, especially the yolks, contain a compound called phosvitin, which can bind to iron and reduce its absorption. Avoid eating eggs alongside iron-rich meals.
• Polyphenols in tea and coffee can decrease iron absorption. Avoid drinking tea or coffee with meals, especially if you have an iron deficiency.
• Soy protein and certain types of fiber, like wheat bran, can also inhibit iron absorption. Try to consume these foods separately from iron supplements or iron-rich meals.
• While not a food, it's worth noting that antacids containing calcium can also reduce iron absorption. Avoid taking iron supplements with antacids.
• Spinach and other leafy greens contain oxalates, which can bind to iron and reduce its absorption. Cooking these vegetables can help reduce oxalate levels and improve iron availability.
