Getting the most from your treatment

For anal or genital warts:

  • Treatment usually continues until the warts have cleared, but if after 16 weeks the area has not cleared, you must stop using imiquimod and see your doctor.
  • Be careful to ensure the cream is applied only to the wart. If the cream spreads to normal skin or if you use too much cream it may result in a severe local skin reaction including reddening, swelling, flaking or breaking of the skin.
  • Men treating warts underneath the foreskin should wash the affected area every day.
  • Imiquimod cream should not be applied before sexual activity.
  • The cream may damage latex condoms or diaphragms so effective contraception should be discussed with your doctor or pharmacist.

For basal cell carcinoma:

  • Do not use sunlamps or tanning beds and avoid sunlight as much as possible during treatment.

For actinic keratosis:

  • Continue treatment for four weeks. If the lesions have not all cleared up 4 weeks after this, a further four weeks treatment may be necessary.
  • Do not use sunlamps or tanning beds and avoid sunlight as much as possible during treatment.
