Adults and Adolescents
This medicine is for topical application to the scalp. The hair should be wetted and sufficient amount applied to produce abundant lather. The scalp and adjacent areas should be vigorously massaged with the fingertips. The hair should be then thoroughly rinsed and the procedure repeated.

Longer duration of therapy should be continued under the supervision of a physician.
Use in the Elderly
The dosage instructions given above are suitable for the elderly.
Use in Children
Not established for use in children under the age of 12 years.
Coal tar preparations have been used, for many years, when recommended by a doctor to treat children however, there is very little documented clinical data in this patient population.
Use in Renal/Hepatic Impairment
No dosage adjustment is necessary
4.3 Contraindications
• Known hypersensitivity to the active substance or to any of the excipients.
• Infected open skin lesions.
• Sore or acute pustular psoriasis
4.4 Special warnings and precautions for use
This medicine is for cutaneous use only.
• Coal tar preparations may cause irritancy, therefore contact with sensitive areas, such as broken or very inflamed skin, should be avoided.
• If irritation develops, treatment should be discontinued.
Contact with the eyes should be avoided. If contact occurs rinse eyes thoroughly with water.
• This medicine may cause increased sensitivity to sunlight, sunlamps should not be used and deliberate or prolonged exposure of the scalp to sunlight should be avoided or minimised.
• This medicine can stain skin and clothes. Contact with clothes should be avoided. Skin stains will wear off after treatment is stopped.
• In rare instances, temporary hair colour changes may occur.
4.5 Interactions with other medicinal products and other forms of interaction
This medicine should be used with caution if the patient is also taking drugs known to be photosensitisers (e.g. thiazides, tetracyclines, fluoroquinolones, phenothiazines, sulfonamides) because of the increased possibility of augmented photosensitivity.
4.6 Fertility, pregnancy and lactation Fertility
There are no data on the effects of topical coal tar preparations on human fertility.
This medicine should be used in pregnancy only when clearly necessary. Pregnancy
There are limited data from the use of coal tar preparations in pregnant women.
Coal tar has been shown to be foetotoxic and teratogenic to the offspring of laboratory animals when administered topically, orally or by inhalation at high and maternally toxic doses (see section 5.3).
Use of this medicine during pregnancy should only be considered if the expected benefit to the mother outweighs the potential risk to the foetus.
The use of this medicine should be avoided in the first trimester of pregnancy.
Lactation
The safe use of topical coal tar preparations during lactation has not been established.
It is not known whether the topical application of coal tar preparations could result in sufficient systemic absorption to produce detectable amounts in breast milk.
Use of coal tar preparations during lactation should only be considered if the expected benefit to the mother outweighs the potential risk to the infant.
If used during lactation, patients should be advised to ensure that any residual product is fully washed off the breast prior to breast-feeding in order to avoid accidental ingestion by the infant.
4.7 Effects on ability to drive and use machines
No effect on the ability to drive and use machines have been observed.

Treatment
Management should be as clinically indicated or as recommended by the national poisons centre, where available.
5 PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
ATC Code: D05AA
Tar preparations have been used extensively for over 50 years in the management of various skin conditions such as psoriasis, eczema and other dermatoses. The precise mechanism of action is uncertain. Coal tars are known to suppress DNA synthesis in hyperplasic skin, inhibiting mitotic activity and protein synthesis. They decrease epidermal proliferation and dermal infiltration and thus promote a return to normal keratinisation. Coal tar has anti-inflammatory, antibacterial, antipruritic, keratolytic, keratoplastic and vasoconstrictive effects.
This is of significance in the management of psoriasis and other dermatoses associated with increased cell replication, such as dandruff. The use of coal tar preparations in products for scalp disorders is well established and such treatments have generally been shown to be safe and effective.
5.2 Pharmacokinetic properties
In a study using a variety of coal tar preparations total urinary poly aromatic hydrocarbons were significantly elevated in patients treated dermally for different forms of dermatoses. The treatment period was for an average of 7 days using 1.5% -40% coal tar preparations over a body surface area that ranged from 9 to 90%. Therefore some of the hydrocarbons present in coal tar may be absorbed through the skin. The highest levels absorbed depend largely on the body surface area treated and on the duration of exposure.
Many of the hydrocarbons will be subject to extensive metabolic transformation by both oxidation and conjugation. Drug-metabolizing enzymes (both in the skin and systemically) may be induced by coal tar application.
The potential for systemic absorption of coal tar from this medicine, containing 4% Coal Tar Solution BP, when used as wash-off shampoo is extremely low.
5.3 Preclinical safety data
Carcinogenesis and Mutagenesis
No long term studies have been conducted with the product formulations. Coal tar contains certain chemicals that are mutagenic to microorganisms and mammalian cells in vitro. Topical and oral administration of high doses of coal tar to laboratory animals induces DNA adduct formation.
High dose administration of coal tar to laboratory animals is carcinogenic However, epidemiological evidence that includes prospective and retrospective studies in thousands of patients receiving coal tar therapy followed for more than 40 years do not suggest a potential increased risk of skin or systemic cancer.
Reproductive Toxicology
Coal tar is foetotoxic and teratogenic at maternally toxic doses following dermal application, oral administration, or inhalation.
