Take Ferrous Gluconate by mouth, usually 1 to 2 times daily, or as directed by your doctor.

Tips for Use:

• Take on an empty stomach for best absorption (1 hour before or 2 hours after meals)
  
  
• If it upsets your stomach, you may take it with food
  
  
• Swallow tablets with a full glass of water
  
  
• Do not chew or crush extended-release tablets
  
  
• If using liquid iron, use a measuring spoon, not a household spoon
  
  

Missed Dose:

• Take it as soon as you remember
  
  

If it’s close to your next dose, skip the missed one — do not double the dose

Ferrous Gluconate works by giving your body the iron it needs to make healthy red blood cells. When you take it, the iron is absorbed in your stomach and intestines and enters the bloodstream.

Your body uses this iron to make hemoglobin. Hemoglobin is very important because it carries oxygen from your lungs to the rest of your body. When your iron levels increase, your body can make more red blood cells and you begin to feel more energetic and healthy.

Ferrous Gluconate contains less elemental iron per tablet than other forms like Ferrous Fumarate or Ferrous Sulfate, so it is gentler on the stomach.

Ferrous Gluconate is usually well-tolerated, but some people may experience side effects.

Common side effects:

• Constipation
  
  
• Stomach cramps
  
  
• Nausea
  
  
• Vomiting
  
  
• Diarrhea
  
  
• Dark-colored stools (this is normal and not harmful)
  
  

Rare but serious side effects:

• Allergic reactions (rash, itching, swelling, trouble breathing)
  
  
• Iron overload (too much iron in the body)
  
  
• Severe stomach pain or bloody stools
  
  

To reduce side effects:

• Take with food if your stomach is sensitive
  
  
• Drink plenty of water
  
  
• Add fiber to your diet to help with constipation
  
  

Always tell your doctor if side effects are serious or do not go away.

Before using Ferrous Gluconate, tell your doctor if you have:

• Stomach ulcers or other digestive problems
  
  
• Hemochromatosis (iron overload condition)
  
  
• Liver disease
  
  
• Diabetes
  
  
• Allergies to iron products
  
  

Important Precautions:

• Keep this medicine away from children – even a small overdose of iron can be deadly for young children
  
  
• Do not take other iron supplements at the same time unless told by your doctor
  
  
• If you are pregnant or breastfeeding, only use it if prescribed
  
  

Do not stop taking the medicine too soon — it may take several weeks or months to fully treat anemia.

Some medications can interfere with how your body absorbs Ferrous Gluconate. Be sure to tell your doctor if you are taking:

• Antacids or acid reducers

• Thyroid medications
  
  
• Certain antibiotics (such as tetracycline or ciprofloxacin)
  
  

To avoid interactions:

• Take Ferrous Gluconate 1–2 hours before or after other medicines
  
  

Take with Vitamin C (like orange juice) to help your body absorb more iron

Adults:

• Typical starting dose: 1 tablet (300 mg) once or twice daily
  
  
• Each 300 mg tablet contains about 35 mg elemental iron
  
  

Pregnant Women:

• May be advised to take 30–60 mg elemental iron per day
  
  
• Always follow the doctor’s prescription
  
  

Children:

• Dose depends on age and weight
  
  
• Liquid form is usually preferred
  
  
• Should be given only under medical supervision
  
  

Tips:

• Take for as long as your doctor recommends — often several months
  
  

Blood tests may be needed to monitor your progress

Ferrous Gluconate is often available over the counter, especially in low doses. However, in some cases, a doctor may prescribe a higher dose if your anemia is more serious.

You may need a prescription if:

• Your doctor wants you on high-dose iron
  
  
• You are pregnant and need medical monitoring
  
  
• You have another condition that affects iron absorption
  
  

Do not take Ferrous Gluconate without confirming iron deficiency, because too much iron in the body can harm the liver, heart, and other organs
