Important information about some of the ingredients

This medicine contains....

  • less than 1mmol sodium (23mg) per 10ml dose, that is to say essentially ‘sodium-free’. • 10g of liquid maltitol per 10ml dose (calorific value 2.3kcal/g). This may have a mild laxative effect.

    92765312007 Turn over

    • 800mg sorbitol in each 10ml dose. Sorbitol is a source of fructose, patients with rare hereditary fructose intolerance (HFI) should not take/be given this medicinal product. • sodium hydroxybenzoates and 1.3micrograms benzyl alcohol which may cause allergic reactions (possibly delayed). Do not use for more than a week in young children (less than 3 years old), unless advised by your doctor or pharmacist. Benzyl alcohol has been linked with the risk of severe side effects including breathing problems (called “gasping syndrome”) in young children. Ask your doctor or pharmacist for advice if you are pregnant, breast-feeding or have a liver or kidney disease (as large amounts of benzyl alcohol can build up in your body and may cause side effects (called “metabolic acidosis”)).
    • 5.2 micrograms of sodium benzoate in each 10ml dose.
    • sulfites which may cause severe

      hypersensitivity reactions and bronchospasm.

3. How to use this medicine

Important things you need to know first….

  • Take this medicine before meals on an empty stomach if possible. If Galfer Syrup upsets your stomach, take it with or after food. • Some foods such as tea, eggs and milk may reduce the amount of iron absorbed by the body. Check with the doctor or pharmacist about which foods to avoid.

  • Galfer Syrup may make your stools darker than usual. This is a normal effect of medicines containing iron.
  • Galfer Syrup may blacken the teeth. To help prevent this, rinse your mouth with water after taking.

    • Vitamin C and drinks containing citric acid may increase the amount of Iron absorbed. • If your symptoms have not started to improve after 28 days, you should ask your doctor for advice. • Treatment should not normally carry on for more than 3 months after the iron deficiency has been corrected. Your doctor will advise you when to stop.

      Dosage
