Patient leaflet - Zineryt

1. What Zineryt is and what it is used for

The active substance of Zineryt belongs to the group of antibiotics

for treatment of acne vulgaris, often referred to as pimples or spots. These medicines are used to reduce the growth of bacteria which cause acne.

2. What you need to know before you use

Zineryt

Do not use Zineryt

  • if you are allergic to erythromycin or zinc or any of the other ingredients of this medicine (listed in section 6).
  • if you are allergic to antibiotics of the macrolide group. Your doctor or

    pharmacist will be able to tell you if that is the case.

Warnings and precautions

Talk to your doctor, pharmacist or nurse before using Zineryt.

  • Cross resistance may occur with other antibiotics of the macrolide group and also with lincomycin and clindamycin.
  • Contact with the eyes or the mucous membranes of the nose and mouth should be avoided. However, if this occurs, then rinse the affected area immediately with cold or lukewarm water for several minutes.

Other medicines and Zineryt

Tell your doctor or pharmacist if you are taking, have recently taken or

might take any other medicines.

Pregnancy, breast-feeding and fertility

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

You may use Zineryt if you are pregnant.

You may breast-feed during treatment with Zineryt but do not use this

medicine on the area of your chest.

Driving and using machines

It is not likely that Zineryt affects your ability to drive or use machines.

3. How to use Zineryt

This medicine is for cutaneous use.

Always use this medicine exactly as your doctor or pharmacist has

told you. Check with your doctor or pharmacist if you are not sure.

Instructions for proper use

Wash the affected area first before using Zineryt.

If you want to apply make-up, use the medicine first and let it dry.

Zineryt comes to you in a special bottle with a special applicator pad protected by a cap which you should remove just before use and replace firmly after each use. The pad makes it easy to apply the solution to the whole of the affected area of the skin to be treated.

To use Zineryt unscrew the protective cap, hold the bottle upside down, place the pad against the skin, and spread the solution over the whole of the affected area (including the surrounding skin). The flow of solution can be increased by pressing the pad a little more firmly against the skin.

If you use the applicator properly, just the right quantity should be applied.

But if you do put too much on, blot it off with some tissue, and make sure it does not run into the eyes, nose or mouth. If it does, wash well with plenty of water (see also ‘‘Warnings and precautions” under section 2. What you need to know before you use Zineryt).

Frequency of administration

Usually, Zineryt should be applied all over the affected area and the surrounding skin twice a day.

Duration of treatment

Successful treatment of acne may take several weeks or even months.

The normal treatment time is 10 to 12 weeks.

Consult your doctor if you still have acne at the end of the prescribed course of treatment.

If you use more Zineryt than you should

If you have applied too much Zineryt, blot it off with some tissue.

Swallowing the entire contents of a single pack of Zineryt would mainly lead to symptoms associated with alcohol intake. You should contact your doctor or pharmacist if you or somebody else accidentally swallows this medicine.

If you forget to use Zineryt

Try not to forget to use Zineryt, as missing an application will slow down the healing process. If you have missed an application, use Zineryt when you remember, but leave about three hours before you use it again.

If you stop using Zineryt

If you stop using Zineryt, the original symptoms may come back. Always contact your doctor if you want to stop using Zineryt.

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

Zineryt may cause the following rare side effects (may affect up to 1 in

1,000 people):

  • Temporary stinging or slight redness of the skin.

If you get a very painful rash or burning feeling after using Zineryt which does not go away in a few hours, or gets worse each time you use it, stop using it and tell your doctor as soon as possible.
