Preferred list (P)

ERYTHROMYCIN WITH ZINC ACETATE (Zineryt® lotion)

Topical Retinoids and Related Preparations

ADAPALENE WITH BENZOYL PEROXIDE gel (Epiduo®)

  • Adapalene 0.1% with benzoyl peroxide 2.5%
  • SMC restriction: for use in mild to moderate facial acne when monotherapy with benzoyl peroxide or adapalene is inappropriate.

Prescribing Notes:

  • Risk of irritation with topical retinoids – build up frequency and duration of application over 2 – 3 weeks.
  • Following application of topical retinoids, evidence suggests that systemic exposure is thought to be negligible. However, since risk cannot be excluded, their use is contraindicated during pregnancy as a precaution.
  • Any recommendation for a topical retinoid issued to a patient of childbearing potential will require clearly documented discussion around the need for effective contraception. (oral progestogen-only contraceptives are not considered effective)
  • Women and girls should be advised not to use topical retinoids if planning a pregnancy and to use effective contraception to minimise risk of accidental foetal exposure.
  • If the patient wishes to proceed without effective contraception, all clinicians involved in direct clinical care must be in agreement. The patient must be aware of and understand the possible risks and consequences of declining contraception.
  • All topical treatment should be reviewed after 3 months.
