Cancer Home > Generic Nolvadex

When AstraZeneca stopped making brand-name Nolvadex in 2006, other companies began manufacturing and selling generic Nolvadex. The medication is sold under the name Tamoxifen Citrate tablets, and like the brand-name version, is used to prevent and treat breast cancer. While the FDA considers generic Nolvadex and generic tamoxifen to be equivalent, each may have different inactive ingredients, which can cause problems for people with certain allergies.

Generic Nolvadex: An Overview

Nolvadex® (tamoxifen citrate) is a prescription medication used to treat and prevent breast cancer. It is part of a group of medications called selective estrogen receptor modulators (SERMs).
The drug was manufactured by AstraZeneca Pharmaceuticals. However, AstraZeneca decided to stop making brand-name Nolvadex in 2006. Fortunately, several companies have chosen to make generic Nolvadex.

Who Makes Generic Nolvadex?

Generic Nolvadex is sold under the name Tamoxifen Citrate tablets, and is made by the following manufacturers:
  • Roxane Laboratories
  • Teva Pharmaceuticals
  • Ivax Pharmaceuticals
  • Mylan Pharmaceuticals
  • Barr Laboratories
  • Haines Pharmaceuticals.

Is Generic Tamoxifen as Good as Nolvadex?

All 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 generic versions 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 tamoxifen versions currently available have an "AB" rating, meaning they are considered equivalent to Nolvadex.
However, generic medications are allowed to have different inactive ingredients from the brand-name medication. This might include fillers or dyes or other ingredients, which may cause problems for people with certain allergies or sensitivities.
