Aldara contraindications and warnings


The following is information on contraindications to the use of imiquimod in general, pregnancy, breastfeeding and children. Please note that the contraindications may vary depending on the dosage form of a drug (eg tablet, syringe, ointment).

When should Imiquimod not be used?

Imiquimod should not be used in case of hypersensitivity to the active substance.

Only with special care the physician may prescribe imiquimod at

  • inflammatory skin conditions, because it can lead to aggravation
  • Patients with autoimmune disease, because it too can get worse
  • Patients after organ transplants, because the drug can cause increased rejection
  • damaged skin or previous medical or surgical treatment of the skin; the use may take place only after complete healing
  • hematopoietic disorders.

What should you watch out for during pregnancy and lactation?

Imiquimod has not been used in clinical studies in pregnant women. Animal studies have not shown any direct or indirect harmful effects on pregnancy, unborn childbirth, delivery or offspring development. Nevertheless, the doctor should only give imiquimod to pregnant women if he considers it absolutely necessary.

Although measurable levels of imiquimod in the blood have not been achieved after single or repeated external use, the active substance should not be used during breast-feeding.

What should be considered in children?

Imiquimod is not approved for the treatment of children due to a lack of studies on effects and side effects in this age group.
