Patient leaflet - Acnecide Wash 5% w/w gel

1. What Acnecide Wash is and what it is used for

Wash contains the active ingredient benzoyl peroxide which attacks the bacteria (germs) known as Propionibacterium acnes, one of the main causes of acne.

Wash is used in the treatment of acne. It is used on the face, chest or back for acne, where the skin has a lot of blackheads, spots and pimples.

Wash is only absorbed into the body in very small amounts and has little effect, except on the surface of the skin.

2. What you need to know before you use Acnecide Wash

Do not use Acnecide Wash if you are:

e Allergic (hypersensitive) to benzoyl peroxide or any of the other ingredients of this medicine (listed in section 6). An allergic reaction may include a rash or itching.

e Avoid contact with the eyes, mouth, angles of the nose or other very sensitive areas of the body. If the preparation enters the eye, wash thoroughly with water.

e Acnecide should not be applied to damaged skin.

e Avoid repeated exposure to sunlight or other sources of UV light (e.g. sun bed).
