About Zineryt

  • Zineryt is a prescription-only antibiotic lotion used to treat acne whiteheads and pustules.
  • The active ingredient is erythromycin.
  • Zineryt is applied twice daily to affected areas for 10-12 weeks.
  • Read the patient leaflet for a full list of side effects, cautions, and interactions with other drugs.
  • Step 3 in the Dr Fox treatment plan.

How does Zineryt work?

Zineryt works by reducing the numbers of the skin bacteria (cutibacterium acnes) which are associated with acne.

Zineryt contains erythromycin, which is one of the macrolide group of antibiotics. Other examples of macrolides are clarithromycin and azithromycin. It also contains zinc which helps to reduce the build up of antibiotic resistance and encourages skin healing.

Who is Zineryt for?

Zineryt works especially well on the whiteheads of mild acne. It is recommended at Step 3 of the Dr Fox acne treatment plan. Zineryt is suitable for all ages but Dr Fox supplies to over 18s only.

Who should not use Zineryt

Zineryt contains the very safe antibiotic erythromycin so most people can use it. The exception being allergy to erythromycin or other similar antibiotics (see below).

Do not use on cuts, grazes, sunburn, or eczema.

Do not use at the same time as other antibiotics to treat acne.

How to use Zineryt

Please note: pharmacists are required to pre-mix Zineryt before posting, and once constituted the solution has an 8-week shelf life.

Full instructions are listed in the manufacturer's patient information leaflet.

Wash and dry the acne affected area. Apply Zineryt twice daily using the applicator pad attached to the bottle. Apply thinly, washing off any excess or any solution in contact with the eyes, mouth, or inside the nose.

Allow Zineryt to dry before applying makeup.

It may take a few weeks of use, and up to 8 weeks for best results. If acne gets worse, or there is no improvement after 8 weeks, stop Zineryt and consult a doctor.

Zineryt should be stopped after 10-12 weeks as the acne bacteria may develop resistance to the antibiotic if Zineryt is used more frequently. It can be restarted after a 6 month break if the acne has returned.

Zineryt side effects and cautions

Zineryt does not usually cause side effects.

As Zineryt contains erythromycin it should not be used if there is known allergy to erythromycin or other macrolide antibiotics, e.g. clindamycin, clarithromycin, azithromycin.

If an allergic reaction is suspected, stop the Zineryt and consult a doctor.

Zineryt can be used by pregnant and breastfeeding women, but women who are breastfeeding should not apply Zineryt to the chest area.

Further information is available in the manufacturer's patient information leaflet.

Other acne treatments

A range of acne treatments are available from Dr Fox.

Peeling and anti-inflammatory topical preparations, such as Differin and Epiduo can be used at the same time with Zineryt, although this increases the chances of localised side effects, such as skin irritation. If using a peeling/anti-inflammatory acne treatment as well, use it first and allow it to dry before applying Zineryt.

Other antibiotics used to treat acne are clindamycin found in Duac topical preparation, and Lymecycline, other tetracyclines, and clarithromycin, taken as tablets or capsules.

Some women find that combined contraceptive pills can improve acne.

People with severe acne including scarring, may benefit from seeing a dermatologist to consider Roaccutane (isotretinoin) tablet treatment.

Zineryt FAQs

Do I have to use Zineryt twice a day?

Yes. The antibiotic in Zineryt does not last very long on the skin so it needs to be reapplied twice a day. Using it less often is more likely to encourage resistance to the antibiotic.

How long should I use Zineryt for?

Zineryt should be used for up to 3 months (10-12 weeks) and then stopped. It can be restarted after a break of 6 months if needed again.

Can I wear makeup with Zineryt?

Yes. Makeup can be applied if using Zineryt. Apply it after the Zineryt but make sure that the Zineryt is completely dry first. Use oil-free non-comedogenic, non-acnegenic cosmetics.

Zineryt hasn't worked - what next?

Zineryt needs to be used for at least 8 weeks for the best effect. If acne has not improved by then, either swap to another step 3 treatment, i.e. Duac or Epiduo, or move onto lymecycline capsules from step 4 of the Dr Fox acne treatment plan.
