Medications containing estrogen may affect how anastrozole works. If you are taking any of these medications, speak with your doctor or pharmacist.
Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications that you are taking. Also tell them about any supplements you take. Since caffeine, decongestants, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

If you have taken more than your normal dose, contact your doctor or nearest hospital immediately.

If you miss a dose of this medicine, do not take the missed dose at all and do not double the next one. Go back to your regular dosing schedule.
