1. What Unguentum M is and what it is used for

Unguentum M is formulated to smooth and soften your skin. It replaces oils in your dry skin and stops your skin losing moisture. It will also relieve the itching caused by eczema and dermatitis.

Unguentum M is used to treat dry, cracked and damaged skin caused by conditions like eczema, dermatitis, itchy skin (known as pruritus), or dry harsh scaly skin (known as ichthyosis).

It can also be used for the protection of raw and grazed skin areas.

Unguentum M can also be used to help relieve the symptoms of nappy rash. You can also use Unguentum M instead of soap when washing which will help to prevent the skin drying out.

ADDITIONAL INFORMATION AND EXPLANATIONS FOR PATIENTS

How else can you help your skin?

There are many factors that may worsen dry skin conditions. These are for example low humidity (air conditioning, central heating), excessive bathing or showering and contact with soap, detergents or solvents. Try to avoid these factors. For mild cleansing use soapfree products and consider medicinal bath oils.

If you find that your skin problem gets worse when you come in contact with certain things like e.g. special food ingredients, metal jewellery or detergents please talk with your doctor about it. Your doctor will help you to identify and avoid the things that cause a deterioration of your skin problem.
