Ogen (estropipate) is currently available as a generic. Ogen and estropipate (the generic name for the drug) are considered equivalent, but it is important to keep in mind that the generic version may contain different inactive ingredients from the brand-name version. Generic Ogen tablets are available in three different strengths and are manufactured by several companies, including Watson Laboratories, Barr Laboratories, and Mylan Pharmaceuticals.
Ogen® (estropipate) is a prescription estrogen hormone replacement medication. It is approved for the following uses:
- Preventing osteoporosis in postmenopausal women
- Treating menopausal symptoms, such as vaginal dryness and hot flashes
- Replacing hormones in younger women whose ovaries do not produce enough estrogen.
Brand-name Ogen is made by Pfizer, Inc. However, the patents for Ogen have expired, and the drug is currently available in generic form.
Generic Ogen tablets come in the following strengths:
- Estropipate 0.75 mg (equivalent to Ogen 0.625 mg)
- Estropipate 1.5 mg (equivalent to Ogen 1.25 mg)
- Estropipate 3 mg (equivalent to Ogen 2.5 mg).
The strengths of Ogen and generic Ogen can be confusing. The "official" Ogen strength is calculated in terms of sodium estrone sulfate, while the generic strength is usually given in terms of estropipate (also known as piperazine estrone sulfate). You do not need to understand the differences between the terms; however, it is important to understand that Ogen 0.625 mg is exactly the same strength as estropipate 0.75 mg.
