4.3 Contraindications

The product is contraindicated in patients known to be sensitive to any of the ingredients including sulphur and salicylates, in the presence of acute local infections, or acute pustular psoriasis.

4.4 Special warnings and precautions for use

Do not use if the tube membrane is already perforated. Do not use on inflamed or broken skin. Avoid contact with mouth, mucous membranes and eyes and wash hands immediately after use. Discontinue use if irritation develops.

If symptoms persist after four weeks, a doctor should be consulted.

Cocois may stain fabrics and jewellery.

Instruct patients not to smoke or go near naked flames - risk of severe burns. Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce product build-up but not totally remove it.

4.5 Interaction with other medicinal products and other forms of interaction


4.6 Pregnancy and lactation

If possible Cocois should not be used during pregnancy or lactation. However, inadvertent, accidental exposure is not cause for clinical intervention. Minimal systemic absorption of salicylic acid may occur after topical application. There are no data on the use of coal tar in pregnant or lactation women. It is unknown whether coal tar crosses the placenta or is excreted in breast milk. There is no sufficient clinical experience to establish the safety of sulphur in general during pregnancy and lactation. It is unknown whether sulphur crosses the placenta or is excreted in breast milk.

4.7 Effects on ability to drive and use machines


4.8 Undesirable effects

Coal tar may cause skin irritation, folliculitis and rarely photosensitivity.

Cocois may cause skin irritations, acne like eruptions, dermatititis, folliculitis, alopecia and rarely photosensitivity and hypersensitivity. Discolouration of skin and hair may also occur.

Bronchospasm has been reported very rarely in patients with either pre-existing asthma or a family history of hypersensitivity to salicylates.

Although carcinogenicity of coal tar has been demonstrated in animal studies, no studies demonstrating an increased risk of skin cancer with normal therapeutic use in humans have been reported. There is no unequivocal evidence to link the use of topically applied coal tar products with skin cancer.
