Patient leaflet - Winlevi 10 mg/g cream

1. What Winlevi® is and what it is used for

Winlevi contains the active substance clascoterone that belongs to a group of medicines known as ‘anti-acne preparations for topical use’. The exact way that Winlevi works is not known. It is thought to treat acne by blocking androgens in your skin from making too much sebum (oils that keep your skin moist).

Winlevi is used for the skin (topical) treatment of acne vulgaris in adults and adolescents aged 12 years and older.

2. What you need to know before you use Winlevi®

Do not use Winlevi

  • if you are allergic to clascoterone or any of the other ingredients of this medicine

    (listed in section 6).

Warnings and precautions

  • Talk to your doctor before using Winlevi
  • For topical and external use only.
  • Do not use in eyes, mouth or vagina.
  • Do not apply to other skin problems, cuts, abrasions, eczema or on sunburnt skin.
  • Avoid getting this medicine in your eyes, lips, mouth, corners of the nose or mucous

    membranes. If contact with mucous membranes happens, rinse well with water.

  • Avoid using skin products that may dry or irritate your skin such as:

    • Medicated or abrasive soaps and cleansers
    • Soaps, cleansers and cosmetics that have strong skin drying effects

If you experience a medical emergency (such as an infection) or have surgery, tell your healthcare professional that you are taking Winlevi. Adrenal suppression may cause further issues in these cases. See the “Serious side effects and what to do about them” table (refer to section 4).

3. How to use Winlevi®

Always use this medicine exactly as described in this leaflet or as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Do not give Winlevi to other people, even if they have the same symptoms you have. It may harm them.

Winlevi is to be used on the skin only (topical). Do not use Winlevi in or on your eyes, mouth or vagina.

Before applying this cream, gently wash and dry the affected skin area. Apply a thin, uniform layer of approximately 1 gram, corresponding to 2 fingertip units to the affected area twice a day, once in the morning and once in the evening. When spread on the skin, this should be enough to cover the size of two adult palms or one adult face. Wash your hands after applying the cream.

Contact your doctor at 12 weeks, as it is required to re-evaluate your treatment and decide whether it is necessary to continue or restart treatment after this period.

Use in adults and adolescents

Apply a thin, uniform layer to the affected area twice a day, once in the morning and once in the evening.

If you use more Winlevi than you should on your skin, you will not get rid of your acne any quicker, but your skin may become irritated and red. Contact a healthcare professional, even if there are no symptoms.

If you forget to use Winlevi

If you forget to apply a dose, the next dose should be applied at the usual time. Apply the same amount you usually would. Do not apply extra.

If you stop using Winlevi

If you have any further questions on the use of this medicine, ask your doctor.
