Ferric maltol should be taken as directed by your doctor. Usually, it’s taken twice a day, preferably on an empty stomach, about one hour before or two hours after meals. Swallow the capsule whole with water—do not chew or crush it.

If you miss a dose, take it as soon as you remember. But if it’s almost time for your next dose, skip the missed one. Do not take two doses together.

Always follow your doctor’s advice and read the patient leaflet that comes with the medicine. Continue taking ferric maltol for the full treatment period, even if you start feeling better after a few weeks.

Ferric maltol provides iron to the body in a way that is safe and easy to absorb. It contains ferric iron (Fe³⁺) that is bound to maltol, a natural sugar-like molecule. This helps the iron stay stable in the stomach and get absorbed better in the small intestine.

Once ferric maltol is taken, the body absorbs the iron and uses it to make hemoglobin. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. This process helps improve symptoms like tiredness, dizziness, and weakness caused by low iron levels.

Because of its unique formula, ferric maltol causes fewer stomach problems compared to traditional iron tablets like ferrous sulfate.

Like all medicines, ferric maltol can cause side effects, although not everyone gets them. The most common side effects include:

• Stomach pain
  
  
• Nausea (feeling sick)
  
  
• Diarrhea
  
  
• Constipation
  
  
• Headache
  
  
• Flatulence (gas)
  
  

These side effects are usually mild and go away after a few days. Taking the capsule with food might help reduce stomach discomfort, but this may also lower how much iron your body absorbs.

Less common but more serious side effects include:

• Allergic reactions like rash, swelling, or trouble breathing (rare)
  
  
• Iron overload if taken too long or in high doses
  
  
• Dark-colored stools, which is normal with iron supplements
  
  

If you experience any serious side effects or signs of an allergic reaction, contact your doctor immediately.

Before starting ferric maltol, talk to your doctor about any health conditions you have. Be careful if you:

• Have too much iron in your blood (iron overload or hemochromatosis)
  
  
• Have a history of stomach ulcers
  
  
• Have liver or kidney problems
  
  
• Are pregnant or breastfeeding – Only use if prescribed by a doctor
  
  
• Are taking other iron supplements – Avoid taking multiple sources of iron at the same time
  
  

This medicine is not meant for people who don’t have iron deficiency. Your doctor should do a blood test to check your iron levels before starting treatment.

Tell your doctor about all other medicines and supplements you are taking to avoid harmful interactions.

Ferric maltol can interact with other medicines. Some of the main interactions include:

• Antacids or calcium supplements: These may reduce iron absorption.
  
  
• Certain antibiotics (like ciprofloxacin, tetracycline): These may not work properly when taken with iron.
  
  
• Zinc and magnesium supplements: These may interfere with iron absorption.
  
  

To avoid interactions, take ferric maltol at least 2 hours before or 4 hours after taking these types of medicines.

The standard dosage for adults is:

• 30 mg iron capsule, taken twice daily
  
  

The length of treatment depends on your iron levels and how your body responds. Usually, treatment lasts for at least 12 weeks, but some people may need longer courses.

Do not change your dose without speaking to your doctor. Too much iron in the body can be harmful. Blood tests will be done regularly to monitor your iron levels and adjust the dose if needed.

For children, ferric maltol is not recommended unless advised by a specialist.

If your symptoms don’t improve after a few weeks, or if they get worse, let your doctor know.

Ferric maltol is a prescription-only medicine. It is not available over the counter. A doctor must confirm that you have iron deficiency anemia and decide that this medicine is right for you.

Your doctor will:

• Do a blood test to check your iron and hemoglobin levels
  
  
• Look at your overall health and other medications
  
  
• Give you a prescription with the correct dose and duration
  
  
• Monitor your response to treatment and check for side effects
  
  

Never share your prescription with others. Taking ferric maltol without a real need can lead to iron overload, which is dangerous.

Always store the medicine at room temperature and out of reach of children.

• What is Ferric Maltol used for?
  It is used to treat iron deficiency and iron deficiency anemia (IDA) in adults.
  It is especially useful in people who:

  • Cannot tolerate standard oral iron (e.g., ferrous sulfate)

  • Have inflammatory bowel disease (IBD), chronic kidney disease (CKD), or heart failure

• What are the brand names?
  Accrufer® (U.S.) and Ferracru® (international).

• What is the active ingredient?
  Ferric maltol, a complex of ferric iron (Fe³⁺) and maltol (a natural sugar derivative that enhances iron absorption).

• How does Ferric Maltol work?

  • The maltol component binds iron tightly, forming a stable complex that protects the gut from irritation.

  • The complex is absorbed in the intestine, where the iron is released and used to make hemoglobin and red blood cells.

• What type of medication is it?
  A non-salt oral iron replacement therapy (gentler on the stomach than traditional iron salts).

• How is Ferric Maltol taken?

  • By mouth, as a capsule.

  • Usually one capsule twice daily, taken on an empty stomach (at least 1 hour before or 2 hours after food).

• What are the available strengths?

  • 30 mg ferric iron per capsule.

• How long does it take to work?
  Hemoglobin and iron levels usually improve within 4–12 weeks of daily use.

• What are the common side effects?

  • Mild nausea or stomach discomfort

  • Constipation or diarrhea

  • Abdominal pain

  • Flatulence (gas)

  • Dark stools (harmless and expected)

• Is Ferric Maltol gentle on the stomach?
  Yes — it is specifically designed to reduce gastrointestinal irritation compared to ferrous salts like ferrous sulfate or fumarate.

• Are there serious side effects?
  Rare, but possible:

  • Allergic reaction (rash, swelling, difficulty breathing)

  • Severe constipation or diarrhea

  • Signs of iron overload (fatigue, joint pain, abdominal swelling)

• Who should not take Ferric Maltol?

  • People with iron overload disorders (e.g., hemochromatosis, hemosiderosis)

  • Those with anemia not due to iron deficiency

  • Individuals allergic to ferric maltol or maltol compounds

• Can Ferric Maltol be used during pregnancy?
  Yes — it may be used if oral iron is needed and tolerated. Always consult your healthcare provider before use.

• Can I take it while breastfeeding?
  Yes — very small amounts pass into breast milk and are not expected to harm the infant.

• Can children take Ferric Maltol?
  Currently approved for adults only; safety in children has not been established.

• Does Ferric Maltol interact with other medications?
  Yes — separate from drugs that bind iron or affect absorption, such as:

  • Antacids or calcium supplements

  • Thyroid medication (levothyroxine)

  • Certain antibiotics (tetracyclines, ciprofloxacin)
    Take other medications at least 2 hours before or after Ferric Maltol.

• Can I take Ferric Maltol with food?
  Best absorbed on an empty stomach, but if it causes stomach upset, it may be taken with a light meal.

• Does Vitamin C help with absorption?
  Not necessary — the maltol component already enhances absorption, unlike ferrous iron salts that need Vitamin C.

• Does Ferric Maltol cause black stools?
  Yes — harmless and expected with any oral iron therapy.

• What should I do if I miss a dose?
  Take it as soon as you remember unless it’s close to your next dose — don’t double up.

• How long should I take Ferric Maltol?
  Typically 12–24 weeks or longer, depending on the severity of anemia and your doctor’s recommendations.

• Can Ferric Maltol cause weight changes?
  No — it does not affect weight directly.

• How should I store Ferric Maltol?
  Store at room temperature (20°C–25°C / 68°F–77°F), away from heat, light, and moisture.

• Is there a generic version available?
  Not yet — Accrufer® / Ferracru® are brand-only products.

• Where can I get Ferric Maltol?
  Available by prescription only from pharmacies.
