Patients who use emollient creams for conditions such as eczema, psoriasis and ichthyosis should therefore take precautions such as avoiding smoking cigarettes and washing bedding and clothes frequently to “reduce the build-up of skin cream”.

The medicines watchdog advised patients against using naked flames, or getting close to “anything that may cause a fire while wearing clothing or a bandage that has been in contact with skin creams”.

“If this is not possible, you must take steps to ensure you are safe when you smoke or use naked flames. For example, by using a flameless lighter or e-cigarette, and removing long sleeved or baggy clothing before using a gas hob,” the MHRA added.

“The role of the pharmacist would be to offer advice on how to safely use emollients,” the MHRA told C+D on July 30.

This may include “taking patients through” its toolkit and offering guidance on how to stop smoking, where appropriate.

The MHRA encouraged contractors to use its materials, such as posters and leaflets, in their pharmacies.
