for The name of your medicine is Adapalene/Benzoyl Peroxide Zentiva 0.1%/2.5% gel (called Adapalene/Benzoyl gel throughout this leaflet). Adapalene/Benzoyl gel is used for the treatment of acne. This gel combines two active ingredients, adapalene and benzoyl peroxide which work together but in different ways:
- Adapalene belongs to a group of products known as retinoids and acts specifically on the skin processes that cause acne.

4.1. Therapeutic indications
This medicinal product is indicated for cutaneous treatment of Acne vulgaris when comedones, papules and pustules are present (see section 5.1).
Adapalene/Benzoyl Peroxide Zentiva is indicated in adults, adolescents and children aged 9 years and above.
4.2. Posology and method of administration
The gel should be applied to the entire acne affected areas once a day in the evening on a clean and dry skin. A thin film of gel should be applied, with the fingertips, avoiding the eyes and lips (see section 4.4).
If irritation occurs, the patient should be directed to apply non-comedogenic moisturizers, to use the medication less frequently (e.g. every other day), to suspend use temporarily, or to discontinue use altogether.
The duration of treatment should be determined by the Doctor on the basis of the clinical condition. Early signs of clinical improvement usually appear after 1 to 4 weeks of treatment.
The safety and effectiveness of adapalene/benzoyl peroxide have not been studied in children below 9 years of age.
Method of administration
Cutaneous use only.
Patients should be instructed to wash their hands after applying the medicinal product.
4.3. Contraindications
• Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.
• Pregnancy (see section 4.6)
• Women planning a pregnancy (see section 4.6)
4.4. Special warnings and precautions for use
Adapalene/Benzoyl Peroxide Zentiva should not be applied to damaged skin, either broken (cuts or abrasions), eczematous or sunburned.
Adapalene/Benzoyl Peroxide Zentiva should not come into contact with the eyes, mouth, nostrils or mucous membranes. If product enters the eye, it should be washed immediately with warm water.
If a reaction suggesting sensitivity to any component of the formula occurs, the use of this medicinal product should be discontinued.
Excessive exposure to sunlight or UV radiation should be avoided.
Adapalene/Benzoyl Peroxide Zentiva should not come into contact with any coloured material including hair and dyed fabrics as this may result in bleaching and discoloration.
Excipients
This product contains 40 mg of propylene glycol (E1520) in each gram of gel which is equivalent to 4.00% w/w that may cause skin irritation.
This medicine can contain up to 2.5 mg of benzoic acid per g of gel, as degradation product of benzoyl peroxide. Benzoic acid may cause local irritation.
4.5. Interaction with other medicinal products and other forms of interaction
No interaction studies have been performed.
From previous experience with adapalene and benzoyl peroxide, there are no known interactions with other medicinal products which might be used cutaneously and concurrently with the gel. However, other retinoids or benzoyl peroxide or medicinal products with a similar mode of action should not be used concurrently. Caution should be exercised if cosmetics with desquamative, irritant or drying effects are used, as they may produce additive irritant effects with this medicinal product.
Absorption of adapalene through human skin is low (see section 5.2), and therefore interaction with systemic medicinal products is unlikely.
The percutaneous penetration of benzoyl peroxide in the skin is low and the drug substance is completely metabolised into benzoic acid which is rapidly eliminated. Therefore, the potential interaction of benzoic acid with systemic medicinal products is unlikely to occur.
4.6. Fertility, pregnancy and lactation
Orally administered retinoids have been associated with congenital abnormalities. When used in accordance with the prescribing information, topically administered retinoids are generally assumed to result into low systemic exposure due to minimal dermal absorption. However, there could be individual factors (e.g. damaged skin barrier, excessive use) that contribute to an increased systemic exposure.
Pregnancy
Adapalene/benzoyl peroxide is contraindicated in pregnancy or in women planning a pregnancy (see section 4.3).
There are no or limited amount of data from the use of adapalene topically in pregnant women.
Animal studies by the oral route have shown reproductive toxicity at high systemic exposure (see section 5.3).
Clinical experience with locally applied adapalene and benzoyl peroxide in pregnancy is limited.
If the product is used during pregnancy, or if the patient becomes pregnant while using this medicinal product, treatment should be discontinued.
Breast-feeding
No study on animal or human milk transfer was conducted after cutaneous application of adapalene and benzoyl peroxide gel.
No effects on the suckling child are anticipated since the systemic exposure of the breast-feeding woman to this medicinal product is negligible. Adapalene/Benzoyl Peroxide Zentiva can be used during breast-feeding
To avoid contact exposure of the infant, application of this gel t to the chest should be avoided when used during breast-feeding.
Fertility
No human fertility studies were conducted with adapalene and benzoyl peroxide gel.
However, no effects of adapalene or benzoyl peroxide on fertility were found in rats in reproductive studies (See section 5.3).
