Hypersensitivity to the active substance(s), to other macrolide antibiotics, or to any of the excipients listed in section 6.1.
As with other macrolides, rare serious allergic reactions, including acute generalised exanthematous pustulosis (AGEP) have been reported. If an allergic reaction occurs, the drug should be discontinued and appropriate therapy should be instituted. Physicians should be aware that reappearance of the allergic symptoms may occur when symptomatic therapy is discontinued.
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.

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
It is not expected that overdosage would occur in normal use. Patients showing idiosyncratic hypersensitivity should wash the treated area with copious water and simple soap.
Pharmacotherapeutic group: Anti-acne, ATC code: D10A F52
Erythromycin is known to be efficacious, at 4%, in the topical treatment of acne vulgaris. Zinc, topically, is established as an aid to wound healing. The zinc acetate is solubilised by complexing with the erythromycin, and delivery of the complex is enhanced by the chosen vehicle.
The complex does not survive in the skin, and erythromycin and zinc penetrate independently. The erythromycin penetrates, and is partially systemically absorbed (0 - 10% in vitro, 40 - 50% in animal studies); that portion absorbed is excreted in 24 – 72 hours. The zinc is not absorbed systemically.
Non-clinical data from repeated dose toxicity and reproduction and developmental toxicity studies reveal no additional hazard other than those described elsewhere in the SPC.
Di-isopropyl sebacate, ethanol.
