Heather Drug

Heather Drug Co was a specialty pharmaceutical manufacturer based in Cherry Hill, New Jersey, primarily known for its production of hormone-based therapies. The company specialized in the formulation of generic and branded drugs, including combinations of esterified estrogens and methyltestosterone used to treat menopausal symptoms. In 1986, it was acquired by Unimed Pharmaceuticals, which sought to leverage Heather's manufacturing expertise and product portfolio. Through subsequent industry mergers involving Solvay Pharmaceuticals and Abbott Laboratories, the company's legacy products eventually became part of AbbVie's offerings. Heather Drug Co is often cited in regulatory history due to its role in the production of drugs subject to the FDA's Drug Efficacy Study Implementation (DESI) reviews.
