Forteo is a daily shot. That is a nuicence, but a small price to pay for the only Anabolic, the only osteoporosis medication which will increase bone mass in spongy (cancellous) bone. Diabetics give themselves a daily shot for the rest of their lives. Forteo is for only 2 years and uses a tiny insulin needle.
People worry about the warning that lab rats got Osteosarcoma after being given very high doses of Teriparatide for the equivalent of 70 human years. We have not seen this in humans, or chimps, or monkeys, or dogs. Rats have bones that grow all their lives. We do not give Forteo to growing humans, pregnant women, nursing women, persons with Paget’s Disease or unexplained elevated Alkaline Phosphatase, or persons who have had radiation to their bones.
Remember that you must take adequate Calcium, with food, spread out over 3 meals. You must take enough Vitamin D3 to be able to absorb Calcium. You must eat enough Protein for your OsteoBlasts to make new bone matrix.
Forteo (Teriparatide) increases the thickness of the struts making up spongy (cancellous) bone. Forteo is the only osteoporosis medication to do that. It also makes the hard outer shell (cortical bone) thicker. How? Forteo stimulates OsteoBlasts. They make bone matrix, the collagen protein that is more than 80% of bone.
Forteo also stimulates bone turnover. Healthy bone is constantly being resorbed and replaced. This allows bone to eliminate the micro-cracks that gradually accumulate with activity. Bone is strongest when it is a mixture of older more calcified (stiffer) material mixed thoroughly with younger less calcified (somewhat bendable) material. Cracks cannot enlarge. Strength is better. More force is required to fracture the bone.
Anabolic medication for osteoporosis actually increases bone thickness and strength! Antiresorptive medications for osteoporosis (Fosamax, Alendronate, Actonel, Atelvia, Boniva, Evista, Reclast, Prolia) only preserve bone.
We have talked about all of the Antiresorptive medications over the last 2 months. They are excellent treatment if slowing down the OsteoClasts (cells that eat away your bone) is sufficient. That is not always the case.
Now it is time to talk about something completely different. Anabolic medication stimulates the OsteoBlasts (cells that make new bone matrix). OsteoBlasts can rebuild your bones. If you have Fractures, your bones may need to be rebuilt.
Forteo (Teriparatide) is the only Anabolic medication for osteoporosis in the USA. Close cousins of Forteo are available in other countries.
You may need the Anabolic, Forteo, if you have a hip fracture, multiple other fractures, or if VFA testing reveals a Vertebral Compression Fracture. A DXA T-score well below -2.5 can be reason enough without fracture.
Glucocorticoid (Cortico-Steroid) medications (Prednisone, Steroid Inhalers) specifically supress OsteoBlasts (cells that make new bone). Stimulating the OsteoBlasts with the Anabolic, Forteo, can offset the bone loss from Steroid medications. Smoking also supresses OsteoBlasts, leading to bone loss. Stopping Smoking would be best, but Forteo can help.
Not everyone needs an Anabolic, but some individuals do. A Complete Bone Health Evaluation will tell you if an Anabolic is right for you.

Aunt Henrietta’s 90th birthday party was a triumph. Over 100 friends, neighbors, and relatives attended. She planned and arranged it all herself. This was not the feeble 89 year old of last fall. This was the comeback kid.
6 years ago Henrietta had fallen and broken both wrists and a shoulder in 3 separate incidents. That was before she took Forteo, followed by Prolia. Last year she was sick enough to be falling several times a day. But she did not break anything! Had she broken she would probably not have celebrated her 90th.
Aunt Henrietta waited until age 83 to start taking enough Calcium (Adora Premium Chocolates), enough Vitamin D, and almost enough Protein. Then she waited until she had fractured both wrists and a shoulder before starting osteoporosis medication.
I am not happy that she still falls ocassionally in her 3 level house, but I know that now she doesn’t break anything.
Aunt Henrietta is a triumph.
You don’t have to wait as long as she did to check up on your bone health. Get a Complete Bone Health Evaluation.
