Exemestane (Aromasin) and tamoxifen are both prescription drugs used to treat certain kinds of breast cancer.
Aromasin is available as a tablet that you take by mouth. It comes in both brand-name and generic versions. The generic is called exemestane.
Tamoxifen comes in two forms: a tablet that you take by mouth and an oral liquid solution. The tablet is available only as a generic. The oral liquid solution is also available as the brand-name drug Soltamox.
Your doctor may have you first take tamoxifen, then switch you to Aromasin. This can depend on different factors, such as how well tamoxifen treats your cancer. In some cases, your doctor may have you take both medications.
For more information about how Aromasin and tamoxifen compare, talk with your doctor. They can advise you on the right treatments for you.
