Arimidex contraindications and warnings


Following is information on contraindications to the use of Anastrozole 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 not Anastrozole be used?

Anastrozole should not be used with

  • Pre-menopausal women (menopause) because it is still ineffective at this time
  • severe renal impairment
  • moderate or severe liver disease.

Estrogens and combinations with these hormones should not be given at the same time as they relieve the effects of anastrozole.

What should you watch out for during pregnancy and lactation?

The use of anastrozole is prohibited during pregnancy and lactation, because the safety of the application at this time is not sufficiently proven.

What should be considered in children?

Children should not be treated with the active substance.

Warnings and Precautions

  • If it is not certain that menopause has already occurred, the doctor will need to do a hormone check-up before the treatment to resolve this issue.
  • In women with osteoporosis or osteoporosis risk, bone density should be determined at the beginning of treatment and at regular intervals by the physician.
  • The drug may make doping controls positive.
  • The ability to react can be modified to such an extent as to impair the ability to drive or operate machinery. This applies to a greater extent in conjunction with alcohol.

Sometimes medications release allergic reactions.
If you notice any signs of allergic reaction, tell your doctor or pharmacist immediately.
