4.4 Special warnings and precautions for use
Patients with rectal bleeding or blood in the stool should talk to their doctor before using this product as these conditions may be the symptom of a more serious underlying disorder.
As with all products containing topical steroids, the possibility of systemic absorption should be borne in mind.
Prolonged or excessive use may produce systemic corticosteroid effects. Do not use for more than 7 days unless under the direction of a doctor.
The product should be discontinued and the patient advised to consult a medical practitioner if symptoms do not improve or worsen or if rectal bleeding occurs.
4.5 Interaction with other medicinal products and other forms of interaction
Concurrent use with other corticosteroid preparations, either topically or orally, may increase the likelihood of systemic effects.
4.6 Fertility, pregnancy and lactation
There is inadequate evidence of safety in human pregnancy and there may be a very small risk of cleft palate and intrauterine growth retardation as well as suppression of the neonatal hypothalamic-pituitary-adrenal axis. There is evidence of harmful effects in animals.
Do not use in pregnancy or breastfeeding.

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 at: www.mhra.gov.uk/yellowcard.
4.9 Overdose
No overdose related adverse drug reactions have been identified from the postmarketing data analysis of Balsam Peru, benzyl benzoate, bismuth oxide, bismuth subgallate, hydrocortisone acetate and zinc oxide.
If swallowed, fever, nausea, vomiting, stomach cramps and diarrhoea may develop 3-12 hours after ingestion.
Symptoms of acute oral overdose of bismuth-containing preparations may include nausea, vomiting, renal failure and rarely liver damage. Encephalopathy and discolouration of mucous membranes may occur with chronic overdose.
No cases of Balsam Peru overdose have been identified in the medical literature.
Hydrocortisone normally does not produce toxic effects in an acute single overdose.
Prolonged, use of topical corticosteroids may increase potential for local adverse effects, including steroid atrophy (thinning of the skin), striae (stretch marks), and Telangiectasia (visible blood vessels). Systemic availability after rectal administration is very low, however, excessive administration of corticosteroids may increase the potential for systemic effects, such as hypothalamic-pituitary axis suppression.
Treatment of a large acute overdose should include gastric lavage, purgation with magnesium sulphate and complete bed rest. If necessary give oxygen and general supportive measures. Methaemoglobinaemia should be treated by intravenous methylene blue.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Agents for treatment of haemorrhoids and anal fissures for topical use, ATC code: C05A A01
This product provides antiseptic, astringent, emollient and decongestant properties. In addition, hydrocortisone exerts an anti-inflammatory action.
Bismuth oxide, zinc oxide and bismuth subgallate exert a protective action on mucous membranes and raw surfaces. They are mildly astringent and are reported to have antiseptic properties
Balsam Peru has protective properties and very mild antiseptic action by virtue of its content of cinnamic and benzoic acids. It is believed to promote the growth of epithelial cells.
Benzyl benzoate is used as a solubilizing agent and has mild antiseptic and preservative properties.
Hydrocortisone acetate has the general properties of hydrocortisone and the anti-inflammatory action is of primary interest in the product.
5.2 Pharmacokinetic properties
Systemic absorption of hydrocortisone acetate from the rectum may occur but estimates of the extent of absorption have been variable and have always been less than 30%. Following absorption it is metabolised in the liver and most body tissues before being excreted in the urine. Biological half-life is approximately 100 minutes and it is 90% bound to plasma protein.
The other active ingredients in this product exert their therapeutic effect without being absorbed into the systemic circulation. These observations are supported by evidence from various studies and reviews.
5.3 Preclinical safety data
The active ingredients of Anusol are well known constituents of medicinal products and their safety profile is well documented.
