How does Ipriflavone work?

Ipriflavone may prevent bone strength loss, and help improve the effects of estrogen in preventing osteoporosis. When used in combination with estrogens, it might allow lower estrogen doses to be used in postmenopausal women.

Are there safety concerns?

Ipriflavone is LIKELY SAFE for most people when used with proper medical supervision. It can cause side effects such as stomach pain, diarrhea, or dizziness.

There is some concern that ipriflavone can cause a decreased white cell count (lymphocytopenia) in people taking it for greater than six months. White cell counts should be monitored, especially in people taking ipriflavone long-term.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Not enough is known about the use of ipriflavone during pregnancy and breast-feeding. Stay on the safe side and avoid use.

Weak immune system: Ipriflavone can lower the body's white cell count, making it more difficult for the body to fight off infection. This is especially concerning in people who already have a weak immune system due to AIDS, drugs used to prevent organ rejection after transplant, chemotherapy, or other causes. If you have a weak immune system, check with your healthcare provider before starting ipriflavone.

Low white cell count (lymphocytopenia): Since ipriflavone can cause lymphocytopenia, there is a concern that it might make pre-existing lymphocytopenia worse.
