Side effects

Occasionally: cramping pains form isolated or abdominal colic, more frequent in cases of severe constipation.Reporting of suspected adverse reactionsReporting of suspected adverse reactions that occur after authorization of the medicine is important, as it allows continuous monitoring of the benefit / risk ratio of the medicine. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system at www.agenziafarmaco.gov.it/it/responsabili. By reporting side effects you can help provide more information on the safety of this medicine.

Special warnings

The enema should be practiced only when necessary or when advised by the doctor. The continued use of laxatives can cause addiction or damage of various kinds. Do not use laxatives if abdominal pain, nausea and vomiting are present. If constipation is stubborn, see your doctor. After a short period of treatment without noticeable results, consult your doctor. The abuse of laxatives (frequent or prolonged use or with excessive doses) can cause persistent diarrhea with consequent loss of water, mineral salts (especially potassium) and other essential nutritional factors. In the most severe cases of abuse, dehydration or hypokalaemia may develop, which can lead to cardiac or neuromuscular dysfunction, especially in the case of simultaneous treatment with cardiac glycosides, diuretics or corticosteroids. The abuse of laxatives, especially contact laxatives (stimulant laxatives), can cause addiction (and, therefore, the possible need to gradually increase the dosage), chronic constipation and loss of normal intestinal functions (intestinal atony).Pediatric populationIn children under the age of 12, the medicine can only be used after consulting your doctor. The treatment of chronic or recurrent constipation always requires the intervention of the doctor for diagnosis, prescription of drugs and surveillance during the course of therapy. Consult your doctor when the need for the laxative derives from a sudden change in previous bowel habits (frequency and characteristics of bowel movements) that has lasted for more than two weeks or when the use of the laxative fails to produce effects. It is also advisable that elderly people or those in poor health conditions consult their doctor before using the medicine. Prolonged use can induce a state of dehydration. The product should therefore be used only in occasional administrations.Important information about some of the ingredients ZETALAX enema contains phosphate: -methyl para-hydroxybeonzatewhich can cause allergic reactions (even delayed); -sodium benzoatewhich can be mildly irritating to the skin, eyes and mucous membranes.
