Lactulose Meda – Liquid lactulose uses, dose and side effects


670 mg / ml oral solution
liquid lactulose

What Lactulose meda is and what it is used for

Lactulose Meda is used for

  • constipation and
  • severe liver disease (hospital only).


When lactulose is broken down in the intestine, acids are formed. The acids bind water and increase the volume of the intestine. In this way, the bowel movements are normalized and constipation is counteracted. At normal doses, lactulose does not affect blood sugar and can therefore be used by diabetics.

Severe liver disease

Ammonia is considered an important trigger for changes in the central nervous system in liver disease. The beneficial effect of lactulose in liver disease is probably due to an increase in acidic substances in the colon, which means that elevated ammonia levels in the blood are reduced.
