Hormone therapy (HT) was once the mainstay of treatment for osteoporosis. But because of concerns about its safety and because other treatments are available, the role of hormone therapy in managing osteoporosis is changing. Most problems have been linked to certain oral types of HT, either taken in combination with progestin or alone. If you're interested in hormone therapy, other forms are available, including patches, creams and the vaginal ring.

Discuss the various options with your doctor to determine which might be best for you.

If HT isn't for you, and lifestyle changes don't help control your osteoporosis, prescription drugs can help slow bone loss and may even increase bone density over time. They include:

• Bisphosphonates. Much like estrogen, this group of drugs can inhibit bone breakdown, preserve bone mass, and even increase bone density in your spine and hip, reducing the risk of fractures.

  Bisphosphonates may be especially beneficial for men, young adults and people with steroid-induced osteoporosis. They're also used to prevent osteoporosis in people who require long-term steroid treatment for a disease such as asthma or arthritis.

  Side effects, which can be severe, include nausea, abdominal pain, and the risk of an inflamed esophagus or esophageal ulcers, especially if you've had acid reflux or ulcers in the past. Bisphosphonates that can be taken once a week or once a month may cause fewer stomach problems. If you can't tolerate oral bisphosphonates, your doctor may recommend periodic intravenous infusions of bisphosphonate preparations.

  A small number of cases of osteonecrosis of the jaw have been reported in people taking oral bisphosphonates — such as Fosamax — for osteoporosis. These cases have been primarily associated with active dental disease or a recent dental procedure, such as a tooth extraction. If your doctor recommends a bisphosphonate for osteoporosis, consider getting any needed dental work done before starting this medication. If you currently take an oral bisphosphonate and need a dental procedure, discuss this with your doctor and dentist.

• Raloxifene. This medication belongs to a class of drugs called selective estrogen receptor modulators (SERMs). Raloxifene mimics estrogen's beneficial effects on bone density in postmenopausal women, without some of the risks associated with estrogen, such as increased risk of uterine and, possibly, breast cancers. Hot flashes are a common side effect of raloxifene, and you shouldn't use this drug if you have a history of blood clots. This drug is approved only for women with osteoporosis and is not currently approved for use in men.
• Calcitonin. A hormone produced by your thyroid gland, calcitonin reduces bone resorption and may slow bone loss. It may also prevent spine fractures, and may even provide some pain relief from compression fractures. It's usually administered as a nasal spray and causes nasal irritation in some people who use it, but it's also available as an injection. Because calcitonin isn't as potent as bisphosphonates, it's normally reserved for people who can't take other drugs.
• Teriparatide. This powerful drug, an analog of parathyroid hormone, treats osteoporosis in postmenopausal women who are at high risk of fractures. Unlike other available therapies for osteoporosis, it works by stimulating new bone growth, as opposed to preventing further bone loss. Teriparatide is given once a day by injection under the skin on the thigh or abdomen. Long-term effects are still being studied, so the Food and Drug Administration recommends restricting therapy to two years or less.
• Tamoxifen. This synthetic hormone is used to treat breast cancer and is given to certain high-risk women to help reduce their chances of developing breast cancer. Although tamoxifen blocks estrogen's effect on breast tissue, it has an estrogen-like effect on other cells in your body, including your bone cells. As a result, tamoxifen appears to reduce the risk of fractures, especially in women over age 50. Possible side effects of tamoxifen include hot flashes, stomach upset and vaginal dryness or discharge.

Emerging therapies
A new physical therapy program has been shown to significantly reduce back pain, improve posture and reduce the risk of falls in women with osteoporosis who also have curvature of the spine. The program combines the use of a device called a spinal weighted kypho-orthosis (WKO) — a harness with a light weight attached — and specific back extension exercises. The WKO is worn daily for 30 minutes in the morning and 30 minutes in the afternoon and while performing 10 repetitions of back extension exercises.
