Frequently asked questions
How is paraben mix allergEAZE 16% applied?
Application is performed by qualified healthcare personnel. A small amount of ointment is applied to a test device, which is then placed on healthy skin (usually on the upper back or, if necessary, on the upper arm).
How long does the test last?
The test must be removed by healthcare personnel 48 hours after application. The doctor will then evaluate the results 30 minutes after removal and subsequently after 1 or 2 days.
When should paraben mix allergEAZE 16% not be used?
It must not be used if you are allergic to any of its components, if you have severe or generalized dermatitis, if the skin in the application area already shows pathology, or if the area has been intensely exposed to the sun in the last 4 weeks. It should not be used if general well-being is compromised, for example in the case of infection.
What are the side effects of paraben mix allergEAZE 16%?
Skin reactions may occur at the application site, such as itching, redness, and possible formation of vesicles. Other effects may include light or dark spots on the skin, scarring, irritation, or skin infections. Although there are no documented cases of severe reactions with parabens, systemic allergic reactions (anaphylactic shock) may occur, requiring immediate medical intervention.
Are there interactions with other drugs?
The use of corticosteroids or other drugs that weaken the immune system can cause falsely negative results. If you are undergoing cancer treatments or immunosuppressive therapies, the test should be postponed. It is important to inform the doctor of all medications being taken.
What should I do if I am pregnant or breastfeeding?
The test should not be performed during pregnancy or breastfeeding unless it is considered absolutely necessary. In these cases, it is essential to consult a doctor to decide whether to proceed.
How should the product be stored?

1. What paraben mix allergEAZE 16% is and what it is used for
Paraben mix allergEAZE 16% is a medicinal product intended solely for diagnostic use. The paraben mix allergEAZE 16% patch test is indicated in adult patients with suspected allergic contact dermatitis to methyl parahydroxybenzoate, propyl parahydroxybenzoate, butyl parahydroxybenzoate and ethyl parahydroxybenzoate (also known as methyl p-hydroxybenzoate, propyl p-hydroxybenzoate, butyl p-hydroxybenzoate and/or ethyl p-hydroxybenzoate, or collectively as parabens). It contains methyl p-hydroxybenzoate, propyl p-hydroxybenzoate, butyl p-hydroxybenzoate and ethyl p-hydroxybenzoate, which may provoke contact allergic reactions on the skin.
Allergic contact dermatitis is an inflammatory reaction of the skin caused by repeated exposure to substances to which you are allergic.
This test is administered in a medical setting by a healthcare professional.
2. What you need to know before you use paraben mix allergEAZE 16%
Do not use paraben mix allergEAZE 16%
- If your general well-being is significantly impaired (e.g., you have an infection).
- If you are allergic (sensitive) to any of the ingredients of this medicine (listed in Section 6).
- If you, at the time of testing, have severe or generalised dermatitis. The patch testing should be done after resolution of the acute phase.
- Existing dermatological pathology at the application site of the patch test.
- If your skin has been exposed to UV (sun) light intensively in the test area in the past 4 weeks.
Warnings and precautions
- Before applying the patch test, your doctor will make sure the patch test application area is free of any ongoing skin conditions that may interfere with the test results.
- During the application period, you should avoid wetting the patch test application area (e.g., excessive exercise and sweating, bathing or showering).
- Your doctor should suspend, if possible, your medicines such as corticosteroids that suppress the immune system as these may cause false-negative test results.
- Anaphylactic reactions have been reported very rarely with some substances; however, no anaphylactic reactions with Paraben mix allergEAZE 16% are known in the literature.
- If you have earlier had anaphylactoid reactions, the use of Paraben Mix allergEAZE 16% should be considered carefully.
- Irritant effects have been reported for parabens. Active sensitisation is in general rare for patch tests but possible, and it is probable if a positive reaction occurs approximately 10–21 days after the application of the patch test. A subsequent patch test with a positive reaction within 72–96 hours can be considered a case of active sensitisation from the previous patch test.
Children and adolescents
Data on the use of the Paraben Mix allergEAZE 16% patch test in the paediatric population are available in the scientific literature. The medicinal product should only be tested in children in case of suspected allergic contact dermatitis to parabens on the basis of a careful anamnestic evaluation. Interpretation of patch test results in the paediatric population requires experience and particular caution.
Other medicines and paraben mix allergEAZE 16%
Tell your doctor or healthcare professional if you are taking, have recently taken, or might plan to take any other medicines, including medicines obtained without prescription, before paraben mix allergEAZE 16% is applied. Remember that your doctor may not be aware of what you are taking.
- Corticosteroids and medicines that weaken the immune system (immunosuppressive medicines) can cause false-negative test results. Your doctor will decide if you must stop corticosteroid treatment prior to testing. If you are not sure if any of your medicines contain corticosteroids, talk to your doctor.
- If you are undergoing treatment with medicines against cancer (cytostatic medicines) or immunosuppressive therapy, patch testing should be postponed.
Pregnancy, breastfeeding and fertility
No experimental data are available on the use of the paraben mix allergEAZE 16% patch test in pregnant women.
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or healthcare professional for advice before using this medicine.
Patch testing for allergy should not be carried out during pregnancy or while breastfeeding, unless it is considered absolutely necessary. Your doctor will decide if you should use a patch test or not.
Driving and using machines
Paraben mix allergEAZE 16% is unlikely to affect your ability to drive or use machines. Talk to your doctor about this if you have any concerns.
3. How to use paraben mix allergEAZE 16%
Method of administration
The following steps are performed by qualified healthcare personnel:
- 5 mm of ointment (20–25 mg) is applied into the application chamber of the test device (patch test) using the syringe containing the medicinal product.
- The patch test panel is then applied to healthy, dry skin (usually on the patient’s upper back, or, if not possible, on the skin of the upper arm).
Duration of treatment
- The patch test must be removed by qualified healthcare personnel 48 hours after application. Your doctor will read the test result at least 30 minutes after removal and again 1 day (72-hour reading) or 2 days (96-hour reading) afterwards, when any allergic reactions are fully developed and possible mild irritant reactions have subsided.
- Assessment of skin reactions is performed by the doctor according to an established protocol. Instructions for this assessment can be found in the information for healthcare professionals (see section “ Interpretation ” at the end of this document).

The following adverse reactions have been reported from published scientific literature for patch testing (frequency cannot be estimated from the available data):
- Sensitisation to the substance you are being tested with,
- Skin reactions at the patch test application site. The reactions include itching, reddening of the skin and possibly blistering. These reactions are expected and may indicate a contact allergy,
- Localised transient pale (hypopigmentation) or darker area (hyperpigmentation) of the skin,
- Scar,
- Irritant reactions,
- Infection of the skin at the application site,

If you experience severe discomfort at the patch test application site, it is necessary to contact a doctor.
Your doctor may decide to remove the patch test.
