Special warnings about Arimidex

Because Arimidex may raise the level of cholesterol in your blood, your doctor may periodically do blood tests to check.

Possible food and drug interactions when taking Arimidex

Certain drugs may decrease the effectiveness of Arimidex, including tamoxifen (Nolvadex) and estrogen-containing drugs. Be sure to tell your doctor about any medication you are taking.

Special information if you are pregnant or breastfeeding

If you are pregnant or plan to become pregnant, do not take Arimidex. In animal studies, this medication has caused severe birth defects, including incomplete bone formation and low birth weight; it could be poisonous to your unborn child. Arimidex also increases your chances of having a miscarriage or a stillborn baby. If you should accidentally become pregnant, tell your doctor immediately.

Because of the possibility of Arimidex passing through your breast milk to your baby, you should probably avoid breastfeeding.

Recommended dosage

ADULTS

The usual dose is a 1-milligram tablet taken once a day. If Arimidex is being used as an initial treatment for advanced breast cancer, you will continue taking the medication until it no longer works against the tumor. The optimal duration of therapy for early breast cancer has not been determined.

Overdosage

Although there have been no reports of Arimidex overdose, any medication taken in excess can have serious consequences. If you suspect an overdose, seek medical attention immediately.
