It is now possible to buy both generic and brand-name Arimidex in the United States. The generic versions are made by a number of different companies. Like brand-name Arimidex, the generics come in only one strength: 1-mg tablets.
Arimidex® (anastrozole) is a prescription medication used to treat breast cancer in postmenopausal women. It is part of a group of medications called aromatase inhibitors.
Brand-name Arimidex is manufactured by AstraZeneca Pharmaceuticals. However, the patent for this medication has expired, and generic versions are now available.
Like brand-name Arimidex, the generic version is available in just one strength -- Anastrozole 1 mg tablets. It is made by a number of generic manufacturers, including but not limited to:
- Mylan Pharmaceuticals
- Roxane Laboratories
- Teva Pharmaceuticals.
Is Generic Anastrozole as Good as Arimidex?
Generic medications must undergo certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generics are equivalent to the brand-name medications and assigns a rating to each one.
An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic anastrozole versions currently approved have an "AB" rating, meaning they should be equivalent to Arimidex.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
