PORTOLAC*SYR FL 200ML 66.67G

Portolac 66.67 g/100 ml syrup
Lactitol monohydrate

What it is and what it is used for
Portolac contains the active ingredient lactitol monohydrate, which belongs to a group of medicines called osmotic laxatives. This medicine works by increasing the water content in the intestine, thus promoting the evacuation of soft and bulky stools.

Portolac is indicated in adults and children for the short-term treatment of occasional constipation.

Consult your doctor if you or the child do not feel better or feel worse after 7 days of treatment.

What you need to know before taking the medicine
Do not take/do not give Portolac to the child
• if you or the child are allergic to lactitol monohydrate or any of the other ingredients of this medicine (listed in section 6)
• if you or the child suffer from reduced intestinal transit (for example, intestinal blockage due to an obstruction)
• if you or the child have or may have an intestinal lesion
• if you or the child have any abdominal pain whose cause you do not know
• if you or the child have rectal bleeding
• if you or the child suffer from hydro-electrolytic imbalance (alteration of the concentrations of fluids and salts present in the body)
• if you or the child suffer from galactose intolerance (a type of sugar).

Do not give Portolac to breastfed infants and children with fructose intolerance (another type of sugar).

If you or your child suffer from faecal impaction (a hard and bulky mass of faeces in the intestine caused by constipation), this condition must be treated in another way before using laxatives.

Warnings and precautions
Consult your doctor or pharmacist before taking/giving Portolac to the child.
The treatment of chronic or recurrent constipation always requires the intervention of a doctor for diagnosis, prescription of medicines, and monitoring during therapy.
Consult your doctor:
• when the constipation you, or the child, suffer from is chronic or particularly stubborn. In this case, the doctor will advise you to treat constipation first with a high-fiber diet, sufficient fluid intake, or physical activity
• if you need to undergo electrocauterization procedures (medical procedure used to remove tissue parts) of the intestine
• if you experience nausea or flatulence (gas in the abdomen)
• if you, or the child, have undergone an ileostomy or colostomy (surgical techniques that create an opening in the abdomen to allow faeces to be eliminated externally)
• if the doctor has diagnosed you or the child with an intolerance to certain sugars
• when the need for the laxative results from a sudden change in previous bowel habits (frequency and characteristics of evacuations) that has lasted for more than two weeks or when the use of the laxative fails to produce effects
• if you are elderly and/or debilitated, as the doctor may want to regularly check the levels of salts present in the blood

It is important to correct any hydro-electrolytic imbalance (alteration of the concentrations of fluids and salts present in the body) before starting treatment with a laxative.

Abuse of laxatives
If you, or the child, abuse (frequent or prolonged use or with excessive doses) of laxatives:
• you may experience persistent diarrhea with consequent loss of water, mineral salts (especially potassium), and other essential nutrients;
• in more severe cases, you could experience severe dehydration or a decrease in blood potassium. You could therefore have heart or muscle problems, especially if you are also taking medicines such as cardiac glycosides, diuretics, or corticosteroids, to treat heart diseases or inflammation;
• you can develop dependence (and, therefore, a possible need to progressively increase the dosage), chronic constipation, and loss of normal intestinal functions (intestinal atony).

For these reasons, prolonged use of laxatives without interruption should be avoided and the doctor should try to determine the optimal dosage at the beginning of treatment.

Children
In children and infants, the medicine can only be used after consulting a doctor.

Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
