4. Clinical particulars
4.1 Therapeutic indications

Symptomatic treatment of constipation.

Preparation of the colon and rectum for endoscopic examination.

4.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Haemorrhoids, anal fissures, rectocolitis, anal bleeding, abdominal pain, intestinal obstruction, nausea, vomiting, inflammatory bowel disease, and ileus.

4.4 Special warnings and precautions for use

As with all laxatives, Norgalax should not be administered chronically. Prolonged use can precipitate the onset of an atonic non-functioning colon and hypokalaemia.

Norgalax contains glycerol (E 422). May have a mild laxative effect.

4.5 Interaction with other medicinal products and other forms of interaction

Norgalax may increase the resorption of medicines and is not to be used in combination with hepatotoxic agents.

4.6 Fertility, pregnancy and lactation


There are no adequate data from the use of docusate enema or oral docusate in pregnant women. Animal studies with oral docusate are insufficient with respect to effects on pregnancy and embryonic foetal development.

The potential risk for humans is unknown. As minimal systemic absorption cannot be ruled out following rectal application, Norgalax should be used in pregnancy only if the benefits outweigh the risks.


It is unknown whether docusate is excreted in human breast milk. Animal studies have shown excretion of docusate and its metabolites in breast milk when administered systemically. A decision on whether to continue/discontinue breast-feeding or continue/discontinue therapy with Norgalax should be made taking into account the benefit of breast-feeding to the child and the benefit of Norgalax therapy to the woman.

4.7 Effects on ability to drive and use machines

Norgalax has no or negligible influence on the ability to drive and use machines.

4.8 Undesirable effects

Gastrointestinal disorders: anal burning, rectal pain, rectal bleeding, diarrhoea

Hepatobiliary disorders: cases of hepatotoxicity have been reported with oral intake of docusate taken together with other laxatives.

Skin and subcutaneous tissue disorders: urticaria

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme Website: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

Overdose will lead to excessive purgation which should be treated symptomatically.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Drugs for constipation, enemas, ATC code: A06AG10

Docusate sodium is an anionic surfactant and used as a faecal softening agent. It is considered to ease constipation by increasing the penetration of fluid into the faeces thereby causing them to soften. Norgalax is usually effective in 5 to 20 minutes.

5.2 Pharmacokinetic properties

Norgalax has a local effect in the rectum. Minimal absorption cannot be ruled out even with a rectal application.

5.3 Preclinical safety data

Non-clinical data reveal no special hazard for humans based on studies of acute toxicity, repeated dose toxicity and in-vitro genotoxicity. Docusate sodium has been shown to exhibit developmental toxicity in rodents at oral doses that are maternally toxic and sufficiently in excess of the maximum human exposure indicating little relevance to clinical use. High oral doses given during lactation reduced pup weight and survival which was attributed to docusate and its metabolites present in the milk of the dams.
