Product Information

Lactulose Fresenius Oral Solution is a gentle, effective treatment for constipation. It contains lactulose, which works by drawing water into the bowel to soften stools and make them easier to pass.

This oral solution is not absorbed into the body, making it suitable for ongoing use under pharmacist or doctor supervision. It can be taken with or without food, and usually produces results within 2–3 days. Lactulose can also be used for managing certain liver-related conditions such as portal systemic encephalopathy, under doctor supervision.

Key points:

  • Helps relieve constipation by softening stools and promoting regularity
  • Provides gentle action without harsh stimulant effects
  • Suitable for adults and adolescents aged 14 years and over
  • Can be used in younger children or infants only on medical advice from your doctor
  • Supplied and checked by Irish-registered pharmacists with discreet delivery
  • May be used to help manage liver-related conditions under medical advice

How to use

How to Use Lactulose Fresenius

For constipation (adults and adolescents over 14 years old):

  • Starting dose: 15–45 ml daily (10–30 g lactulose)
  • Maintenance dose: 15–30 ml daily (10–20 g lactulose)
