NIZORAL 20 mg/g shampoo
Ketoconazole
What it is and what it is used for
NIZORAL contains an active ingredient called ketoconazole, which belongs to a group of medicines that kill fungi, known as antifungals. Like other shampoos, NIZORAL also contains other ingredients that are used to clean hair.
NIZORAL shampoo is used against scalp infections caused by a fungus (yeast) called Malassezia. This fungus is found on everyone's skin, but sometimes it can cause problems such as:
• dandruff;
• dry or greasy flaking of the skin, called seborrheic dermatitis.
These conditions can cause itching.
What you need to know before taking the medicine
Do not use NIZORAL
if you are allergic to the active ingredient or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor or pharmacist before using NIZORAL if:
• you are elderly;
• you have liver problems;
• you have previously used medicines containing griseofulvin, which are used to kill fungi.
Be careful with NIZORAL shampoo
• If you are using a lotion or cream containing a corticosteroid (e.g., betamethasone or hydrocortisone) on your scalp:
- continue to apply a small amount of the lotion or cream containing the steroid;
- gradually reduce this amount during the first 2-3 weeks of treatment with NIZORAL shampoo;
- after 2-3 weeks, use only NIZORAL. This will prevent a worsening of symptoms before NIZORAL starts to take effect.
• Avoid contact with eyes. If this happens, rinse your eyes with plenty of cold water.
Like other topical medicines, especially with prolonged therapy, NIZORAL shampoo can cause redness and itching (sensitization phenomena). If this occurs, stop treatment and consult your doctor.
Children and adolescents
NIZORAL shampoo can be used in adolescents over 12 years of age.
