1. What is Duphalac and what is it used for
Duphalac contains a laxative called lactulose, which works by softening the stools for better transit and defecation, pushing water into the intestine. It is not absorbed by the body.
Duphalac is used in the treatment of constipation (infrequent bowel movements, hard and dry stools) to produce semi-solid stools. It is used, for example, when there are hemorrhoids, in anal surgery, or in surgery on the lower part of the intestine. Additionally, it is used for the treatment and prevention of hepatic portosystemic encephalopathy (portosystemic encephalopathy), which is a liver disease that causes difficulty thinking, tremors, decreased consciousness, and even coma.
You should consult a doctor if it worsens or does not improve after several days of treatment.
2. What you need to know before you take Duphalac
Do not take Duphalac:
- If you are allergic to lactulose or any of the other components of this medicine (listed in section 6).
- If you have galactosemia (a severe genetic disorder that prevents the digestion of galactose).
- If you have obstruction, perforation, or risk of gastrointestinal perforation (apart from habitual constipation).
If you have any doubts, consult your doctor or pharmacist.
Warnings and precautions
Consult your doctor, pharmacist, or nurse before starting to take Duphalac.
This medicine contains lactose, galactose, and fructose from the manufacturing process. If your doctor has told you that you have an intolerance to certain sugars, consult with them before taking this medicine.
This medicine may contain sulfites from the manufacturing process. Rarely, it can cause severe hypersensitivity reactions and bronchospasm.
It is advisable to consult your doctor in the following cases:
- If you present symptoms of abdominal pain of unknown cause before starting treatment.
- If, after several days of treatment, the effect of the medicine is insufficient.
- If you are lactose intolerant.
- If you are diabetic.
If you are diabetic and are being treated for hepatic encephalopathy, your dose of Duphalac will be higher. This amount of Duphalac contains a large amount of sugar, so you will need to adjust the dose of your antidiabetic treatment.
- The chronic use of unadjusted doses of Duphalac (which exceed 2-3 semi-solid defecations per day) or misuse can lead to diarrhea and electrolyte imbalance.
Do not use Duphalac without medical supervision for more than two weeks.
