Have you heard of Lecicarbon®? This product is a fast-acting suppository laxative for constipation in adults and children. Not all children need rectal interventions, but for those who are struggling to get the poo in the toilet it can be just what they need. Lecicarbon is one of a range of products suitable for use in children. We asked Aspire, the company who distribute it, to give us some information on it:

Childhood Constipation

Constipation accounts for around 3% of GP visits among children. Signs to watch for include changes in poo patterns, going to the toilet fewer than three times per week and symptoms associated with passing a hard poo, such as bleeding and straining1.

Lecicarbon®: For fast, predictable relief in a natural way

Lecicarbon (sodium hydrogen carbonate; sodium dihydrogen phosphate) is a fast-acting laxative that gets straight to work using a ‘bottom-up’ approach. It can be used for short term treatment of constipation and is available in two forms; Lecicarbon A® for adults and children aged 12 and over, and Lecicarbon C® for children aged between 1 and 12 years.
While traditional oral laxatives must pass through the digestive system and into the bloodstream, Lecicarbon® is a ‘suppository’ laxative, which means it is inserted directly into the bottom to have a fast effect directly where it is needed. It gets to work when the warmth of the body causes it to melt, releasing little bubbles of carbon dioxide (CO2). As with a normal bowel movement, these CO2 bubbles trigger an intestinal movement (peristalsis), which causes the poo to be moved down and out of the bottom3,4.

This predictability means Lecicarbon works on a ‘one in, one out’ basis, with only mild and uncommon side effects, so there’s no need to worry about repeat evacuations. It also has no known drug interactions, is not addictive and doesn’t cause production of mucus, which makes it a suitable choice for young patients and tolerable for use long-term.

Additional Information

The smooth, torpedo-shaped capsules come individually wrapped in packs of 15 for easy and comfortable insertion as and when relief is needed. Some parents find it easier to dip Lecicarbon in water before use.
Lecicarbon® may cause a slight burning sensation upon insertion, that quickly disappears. The suppository is not suitable for use in those with peanut or soya allergies. It cannot be used by those with intestinal obstruction or those with anal or rectal diseases that could lead to an excessive absorption of carbon dioxide. In the presence of toxic megacolon, it should only be used with permission of the treating doctor.

A diagnosis of constipation should be made by your child’s doctor or pharmacist before taking Lecicarbon®. Always read the patient leaflet before taking this product. Further information is available at www.lecicarbon.co.uk

How does this fit in to children's constipation management? 

When further interventions are needed for treating children's constipation, then a stepwise approach should be used, offering smallest and least invasive options first. Download ERIC's Poo Ladder for more information.
