4. Clinical particulars
4.1 Therapeutic indications

A highly emollient and protective hydrating base for regular first-line treatment and prophylaxis of dry or chapped skin conditions which may also be pruritic (itchy) or inflamed. Doublebase may also be used as an adjunct to other topical treatments.

4.2 Posology and method of administration

For external use only. Before using the 500 g bottle, turn the top of the pump dispenser anti-clockwise to unlock it.

For adults, the elderly, infants and children:

• Apply Doublebase to the affected areas as often as necessary. For best results use a few gentle strokes to smooth Doublebase across the skin in the same direction as hair growth. If necessary, allow time for any excess to soak in. Do not rub vigorously.

• Doublebase may also be applied before washing, showering or having a bath to prevent further drying of the skin.

If additional topical treatments are being used on the same skin areas, Doublebase should be applied between these applications.

Although Doublebase has been specially formulated for use on dry, problem or sensitive skin, local skin reactions can occur in rare cases. In this event, treatment should be discontinued.

Reporting of suspected adverse reactions

Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard.

4.9 Overdose

Not applicable.

5. Pharmacological properties
5.1 Pharmacodynamic properties

The oily ingredients, isopropyl myristate and liquid paraffin, encourage rehydration and softening of dry skin by forming an occlusive barrier within the skin surface, thus reducing drying from evaporation of water that diffuses from the underlying layers.

5.2 Pharmacokinetic properties

Because Doublebase is designed to deliver the emollient ingredients into the stratum corneum when gently applied to areas of dry skin, it is relatively non-greasy despite its high oil content.

5.3 Preclinical safety data

No relevant information additional to that contained elsewhere in this SPC.
