Sudocrem is an antiseptic barrier cream that is most commonly used to treat and prevent nappy rash. It may also be used to prevent infection in minor scrapes or burns, and to treat bed sores or even acne.

Who is it for?

Sudocrem’s most common use, as mentioned above, is in the treatment and prevention of nappy rash in babies. Nappy rash is a skin irritation caused by constant exposure to sweat, urine, and faeces (poo). Symptoms include redness, soreness, and cracking of the skin around the genital area where you would apply a nappy. Sudocrem helps form a barrier, protecting the skin from the constant exposure to irritants.

Sudocrem may also be used to treat acne, and minor skin wounds due to its antiseptic properties.

How does it work?

Sudocrem contains the active ingredients: zinc oxide, benzyl alcohol, benzyl cinnamate, and lanolin. Zinc oxide has skin soothing and antibacterial properties. Benzyl alcohol has local anesthetic properties, which may help alleviate discomfort or pain, and benzyl cinnamate has antifungal properties. These functions are why Sudocrem has use in treating minor burns and scrapes as well as acne. Lanolin is a moisturising and skin protecting ingredient that helps form a protective barrier on the skin, preventing irritation caused by constant contact with urine in nappy rash, or moisture in bed sores.

For prevention and treatment of nappy rash: apply a thin layer of the cream to clean and dry skin, in between nappy changes. Smooth gently onto the skin and avoid excessive rubbing. The nappy should also be left off for as long as possible to allow fresh air to circulate and reduce friction irritation.

Should anybody not take it?

Sudocrem should be avoided if you or your baby have a sensitivity to any of the ingredients listed. Care should also be taken to avoid contact with the eyes and mouth.

Are there any side effects?

People may experience a hypersensitivity reaction to Sudocrem. Symptoms include redness or a rash, burning, or stinging. Discontinue use if this occurs and rinse or wipe off. Sudocrem contains lanolin which is flammable. Care should be taken to avoid any contact with an open flame to areas treated with Sudocrem, this includes clothing or bedding which may contain residue.
