What Is Osteoporosis?
Osteoporosis is a condition characterized by decreased bone mass. This leads to fragile bones that are at an increased risk for fractures, typically in the hips, spine, and wrists. The term "porosis" means spongy, which describes what the inside of osteoporosis bones look like. Normal bone marrow has small holes within it, but a bone with osteoporosis will have much larger holes. Osteoporosis occurs most often in women who have gone through menopause. If not prevented or if left untreated, osteoporosis can progress painlessly until a bone breaks.
Why Do More Women Than Men Have Osteoporosis?
There are two main reasons why osteoporosis affects more women than men:
- Estrogen loss associated with menopause causes women's bones to get thin. Without sufficient estrogen, women's bones can't properly absorb or maintain the calcium they need
- Women have lighter, thinner bones, so women are more vulnerable to osteoporosis
The once-a-week CLIMARA® and CLIMARA PRO® transdermal patches may help slow the amount of bone loss, prevent osteoporosis and the fractures it can cause, and provide relief from menopausal symptoms.
Ask your healthcare provider if the CLIMARA patches may be right for you.
Important Safety Information
What is CLIMARA used for?
CLIMARA is used after menopause to:
- Reduce moderate to severe hot flashes
- Treat moderate to severe dryness, itching, and burning in or around the vagina
- Treat certain conditions in which a young woman's ovaries do not produce enough estrogen naturally
- Help reduce your chances of getting osteoporosis (thin weak bones)
When prescribing solely for vaginal dryness or osteoporosis, other treatments should be considered.
What is the most important information I should know about CLIMARA (an estrogen hormone)?
- Estrogens increase the chances of getting cancer of the uterus.
Report any unusual vaginal bleeding right away while you are taking estrogens. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.
- Do not use estrogens with or without progestins to prevent heart disease, heart attacks, strokes, or dementia.
Using estrogens with or without progestins may increase your chances of getting heart attack, strokes, breast cancer, and blood clots. Using estrogens with progestins may increase your risk of dementia.
You and your healthcare provider should talk regularly about whether you still need treatment with CLIMARA.
What is CLIMARA PRO used for?
CLIMARA PRO is used after menopause to:
- Reduce moderate to severe hot flashes.
- Help prevent osteoporosis (thin weak bones).

What is the most important information I should know about CLIMARA PRO (combination of estrogen and progestin hormones)?
- Do not use estrogens with or without progestins to prevent heart disease, heart attacks, or strokes.
Using estrogens and progestins may increase your chances of getting heart attacks, strokes, breast cancer, and blood clots.
- Do not use estrogens with or without progestins to prevent dementia
Using estrogens with progestins may increase your risk of dementia.
You and your healthcare provider should talk regularly about whether you still need treatment with CLIMARA PRO.
