Regulax Picosulfate oral drops are a laxative. Regulax Picosulfate oral drops are used for constipation and disorders which require easier passage of stools. As with other laxatives, Regulax Picosulfate oral drops should not be used for long periods without a medical evaluation of the causes of constipation.
Do not take Regulax Picosulfate:
– if you are allergic to sodium picosulfate, other active substances from the triarylmethane group or any of the other ingredients.
– if you have narrowing of the intestines with impaired bowel passage, bowel obstruction, acute abdominal complaints such as appendicitis, severe abdominal pain associated with nausea and vomiting
– if you have an acute inflammatory disease of the gastrointestinal tract
– if you are severely dehydrated
– children under 4 years of age.
Constipation associated with other complaints, such as abdominal pain, vomiting and fever may be a sign of serious illness (bowel obstruction, acute abdominal inflammatory disease). In such case, you must not use Regulax Picosulfate and you should talk to your doctor immediately.

This product contains 450 mg sorbitol per ml solution (20 drops). Sorbitol is a source of fructose.
