SMTL Dressings Datacard

Product Name: Viscopaste PB7
Classification Name: Bandage Zinc Paste BP
Manufacturer: Smith & Nephew Healthcare Limited


Viscopaste PB7 is an open-wove bleached cotton bandage impregnated evenly with a paste containing 10% Zinc Oxide BP together with Glycerol BP, Cetostearyl Alcohol BP, Cetomacrogol BP, White oil BP, Guar Gum, Xanthum Gum, Methyl p-hydroxybenzoate BP, propyl p-hydroxybenzoate BP and Purified Water BP.

The bandage is off-white in colour and supplied rolled ready to use.


Viscopaste PB7 is used as an adjunct to compression therapy in the management of leg ulcers, where venous insufficiency exists and in the treatment of chronic eczema/dermatitis where occlusion is indicated.


Viscopaste PB7 should not be applied to patients known to be sensitive to one of the ingredients of the dressing. The dressing should not be applied to acute eczematous lesions and grossly macerated skin.

Method of use

Viscopaste PB7 should be applied to the leg in a series of loose folds rather than a continuous spiral to ensure that it cannot constrict blood flow or cause a tourniquet effect. When used in the treatment of venous leg ulcers, the bandage should be used in conjunction with a suitable compression bandage to aid venous return and help to prevent the paste bandage from drying out. When compression is not required, Viscopaste PB7 should be covered with a non-elasticated tubular bandage to reduce drying out and to prevent the soiling of clothing.

Frequency of Change

Viscopaste PB7 may be renewed as frequently as the condition requires.


Some patients, particularly those with leg ulcers, have skin that is easily sensitised to topical medicaments including the preservatives used in the formulation of some paste bandages. If changes occur in the appearance of skin surrounding an ulcer dressed with Viscopaste PB7, sensitisation should be suspected. Such patients should be referred for specialist diagnosis including patch testing.

One of the functions of occlusive bandages is to increase absorption of topical medicaments. Care should therefore be taken if topical steroid preparations are used under these bandages as their absorption may be significantly increased.


Viscopaste PB7 is supplied individually wrapped, sealed in a polythene bag contained in a cardboard carton.


Viscopaste PB7 should be stored in a dry place not exceeding 25 C.
