Undecided choice of drugs for Osteoporosis
I am 80 years old women and have borderline osteoporosis which affects my entire body. My doctor wants me to take Prolia and the Rheumatologist wants me to take Reclast. I’m unhappy with both choices as the side effects are great and I do not tolerate new drugs well. I am very undecided and am considering doing not taking annty drugs for this condition. I have never had a fracture and I’m very active Any opinions or advice.

I am sure the Physicians Desk Reference did not make this up.
Of course but I am just saying I need the study it is based on. My doc would not accept this. I have been hoping to influence his practice which is unrealistic I guess.
This is from the PDR website so there may be more information available to prescribers than you or I can access.

janflute, the scariest effects of Reclast affect only (yikes) about 22%. There is a way to reduce the percentage to about 1% according to the well-known bone expert who conducted the reclast clinical trials.

"I have prescribed a lot of Reclast (zoledronic acid), which to my knowledge is always administered in an infusion center, and not in a physician's office. My strong recommendation based on my knowledge of bisphosphonates (given that I helped to develop three of them, and treated 13,000 patients in phase 3 trials with them) is to have the infusion center dilute the 5 mg of zoledronic that comes in 100 mL of D5W into 500 mL of NS, and infuse the endodoc recnow 600 mL over 60 minutes. Making the drug more dilute and administering it more slowly significantly improves the renal safety for N-containing bisphosphonates.I also strongly recommend that the infusion nurses give the patient 650 mg of acetaminophen (Tylenol) at the time of the infusion, and that the patient take that same dose with dinner and at bedtime the day of the infusion, with all 3 meals and at bedtime the day after the infusion, and a final (7th) dose of acetaminophen with breakfast the 2nd morning after the infusion. These 8 doses total of Tylenol reduce the chance of a symptomatic APR (Acute Phase Reaction) from 22% to < 1%.Best, endodoc." (Karpf)

Reclast (zoledronate) adheres more strongly to the bone and persists in the bone for a longer period of time than Fosamax (alendronate). Risidronate has the least adherence and for the shortest duration. If my tentative plan fails, I will take risidronate to lessen the reductive impact of bisphonates on the second application of Forteo.
Osteoclasts and osteoblasts work best when coupled. Forteo, Tymlos too, establish a period of time when stripping the bone of fissures combines with laying down new bone in perfect balance--the bone anabolic window. An advantage of the balance is that osteoblasts are said to changed into osteocytes in the bone itself and they are the cells responsible for remodling.
My plan for myself is to follow the bone markers to maintain and then reestablish the anabolic window without sacrificing too many osteoclasts and without the bisphosphonates that prevent osteoblasts from penetrating the bone or from seating new bone.
It appears from my markers that after seven months I should have stopped Forteo. As it was at eight I stopped for one month and had the robust rise in osteoblasts and drop in osteoclasts with resumption. The markers may dictate the use of a bisphosphonate. I would then choose Actonel) risidtonate as it is the least "effective."
@gently are you saying that Forteo's bone-building action was renewed by taking a break?
Great post by the way.
Thank you for your reply. Please keep in touch and share how you are doing.🙏
windyshores, the bone markers indicate a jump in osteoblasts and a bigger drop in osteoclasts. The bone markers are saying something. Future markers may indicate that the change was temporarily enhanced by disturbed molecular rhythm in the bone, or that the renewal was just beginning.
I'll say that it looks like Forteo's bone-building action was renewed by a 30 day break.
Markers for bone building cells rise for one month after Evenity before falling back to baseline. Markers for acid secreting cells increase for up to twelve months. It makes sense to take Forteo or Tymlos beginning a month after Evenity, because these drugs raise the level of declining osteoblasts. I like six months of Forteo before a bisphosphonate.
Interesting info that I have not heard before. I need to ask some questions so I can understand all these points better.
Where did you get the 22% have serious reactions to Reclast? That's a scary high number.
Who are you quoting about how to infuse Reclast? Can you provide a link?
I've seen people on Facebook saying they get slow infusions and some adding adding a saline solution but I don't believe I ever see where that info originates.
I was already wondering about how to get a longer infusion if I go the Reclast route next. My doc said 20 min while your quote says an hour plus a sodium chloride solution plus Tylenol.
I wonder why so much Tylenol? Does Tylenol protect the kidneys from Reclast (while being chancy for the liver, imo, at the same time)?
On your Risidronate strategy, is there any study showing it holds on to your gains from an anabolic as well as Reclast? And is there any study showing Risidronate can be followed more successfully with an anabolic than Reclast or Fosamax? I get that it seems logical but I wonder if there is any research showing this.
Thanks for the new info
The person claims to have treated 13,000 patients. That would be 26 a day for a 2 year trial. (assuming 250 wotking days a year.). That is a lot of people being treated.
