1. What is Duphalac and what is it used for
What is Duphalac
- Duphalac contains the laxative substance lactulose. It softens the stool and facilitates its passage by allowing water to penetrate the intestine. It is not absorbed into the body.
What it is used for
- Duphalac is used to treat constipation (slow bowel movements, hard and dry stools) and to soften the stool, for example:
- if hemorrhoids (anal varices) are present
- after surgeries in the anal or large intestine area
- Duphalac is used to treat hepatic encephalopathy (a liver disease that causes confusion, tremors, decreased level of consciousness, including coma).
2. Important information before taking Duphalac
When not to take Duphalac
- If the patient is allergic (hypersensitive) to
- lactulose
- or any of the other ingredients of Duphalac (see section 2 and 6).
- If the patient has:
- galactosemia (a severe genetic disorder that prevents the digestion of galactose)
- gastrointestinal obstruction (except for normal constipation)
- perforation or risk of gastrointestinal perforation
In case of doubt, the doctor or pharmacist should be consulted before taking Duphalac.
Warnings and precautions
Before starting to take Duphalac, the doctor or pharmacist should be consulted if the patient has any diseases, especially:
- if the patient has unexplained abdominal pain
- if the patient does not tolerate lactose (milk sugar)
- if the patient has diabetes.
Duphalac should not be taken if:
- there is galactose or fructose intolerance
- there is a lack of lactase type Lapp
- there is poor absorption of glucose-galactose.
In patients with diabetes and also being treated for hepatic encephalopathy, the dose of Duphalac will be higher. This higher dose may contain a large amount of sugar. Therefore, it may be necessary to adjust the dose of antidiabetic drugs.
It should be taken into account that during treatment, the bowel movement reflex may be disturbed.
Chronic intake of unadjusted doses (appearance of more than 2-3 soft stools per day) or abuse may lead to diarrhea and electrolyte disturbances.
During the use of laxatives, it is recommended to drink an adequate amount of fluids (about 2 l/day, i.e. 6-8 glasses).
If Duphalac is taken for several days and there is no improvement or worsening of symptoms, the doctor should be consulted.
Children
In special cases, the doctor may prescribe Duphalac for use in children, infants, or newborns. In such cases, the treatment will be closely monitored by the doctor.
