1. What Peroxiben is and what it is used for
Benzoyl peroxide, the active substance in this medicine, has antimicrobial and sebostatic (sebum-regulating) activity, and is capable of inhibiting the growth of Cutibacterium acnes, the microorganism responsible for acne.
Peroxiben is indicated for the local symptomatic treatment of moderate vulgar acne in adults and adolescents aged 12 years and older.
You should consult a doctor if your condition worsens or does not improve after 6 weeks.
2. What you need to know before using Peroxiben
Do not use Peroxiben
-
if you are allergic to benzoyl peroxide or to any of the other ingredients of this medicine (listed in section 6).
-
Warnings and precautions
-
Consult your doctor or pharmacist before starting to use Peroxiben
-
if you have very sensitive skin.
-
This medicine may cause skin irritation and some redness.
During the first application, you may experience mild stinging, redness, and skin peeling.
During the first weeks of treatment, peeling may suddenly increase in most patients. This usually subsides within one or two days if treatment is temporarily interrupted. To prevent this effect, it is recommended to start treatment on a small area and gradually extend it to the affected area after a few days.
If mild irritation occurs, applications should be spaced out.
If irritation persists or is severe, discontinue use of Peroxiben and wash the skin carefully with water and soap. If irritation continues after stopping treatment, consult your doctor.
- Do not use Peroxiben on damaged or eczematous skin, or on cuts or abrasions, due to the possible risk of absorption. Avoid contact with eyes, lips, mouth, nostrils, mucous membranes, and sensitive areas of the neck. In case of accidental contact, rinse immediately with water.
- Use of Peroxiben may cause discoloration of hair and certain dyed or colored fabrics.
Other medicines and Peroxiben
Inform your doctor or pharmacist if you are using, have recently used, or might need to use any other medicines.
Do not use Peroxiben together with other medicines or cosmetics that have peeling, irritating, or drying effects.
Peroxiben may be used in combination with other substances indicated for the treatment of seborrhea and acne, under medical supervision.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.
Peroxiben should only be administered to pregnant women when a physician determines that the benefit outweighs the potential risk, as the safety of benzoyl peroxide has not been established.
It is unknown whether Peroxiben is excreted in breast milk; therefore, it should be used with caution in breastfeeding women, and should not be applied to the breast to avoid transfer to the infant.
Driving and using machines
There is no evidence that Peroxiben affects the ability to drive or operate machinery.
3. How to use Peroxiben
Follow exactly the instructions for administering this medicine as described in this leaflet or as directed by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist.
Use in adults and adolescents aged 12 years and older
After washing the affected area with water and soap, apply a small amount of Peroxiben with the fingertip to the affected area once or twice daily, depending on the severity of the condition and skin tolerance.
It is advisable to start treatment with Peroxiben 25 mg/g gel, switching to Peroxiben 50 mg/g gel or 100 mg/g gel after 3 or 4 weeks, or earlier if good tolerance to Peroxiben 25 mg/g gel is established.
Improvement is generally observed after 4–6 weeks of treatment. However, longer-term use may be required.
Use in children under 12 years of age
Do not use Peroxiben in children under 12 years of age without medical supervision.
If you use more Peroxiben than you should
If you have used more Peroxiben than recommended, consult your doctor or pharmacist immediately. If an excessive amount of Peroxiben has been applied, the skin may become excessively red and painful. In such cases, reduce the frequency of application until this phase passes. If irritation persists, consult your doctor.
In case of accidental ingestion, do not induce vomiting. Rinse the mouth and seek immediate medical attention.
In the event of overdose or accidental ingestion, contact the Toxicology Information Service: Telephone: 91.562.04.20.
If you forget to use Peroxiben
If you forget to apply a dose, apply it as soon as possible and continue treatment as before. Do not apply a double dose to make up for a missed dose.
If you have any further questions about the use of this medicine, ask your doctor or pharmacist.
