Side effects from Zoledronic Acid?

Posted by jo2184 @jo2184, May 28 4:49pm

Have you or someone you know had negative side effects from a Zoledronic Acid (Reclast) injection? After 3 1/2 years of taking alendronate sodium tablets, my recent Dexa scan shows a decrease in my hip bone density. So my endrocronologist recommends that I start taking Zoledronic Acid injection. However, I'm hesitant since it has a long list of possible negative side effects. I would appreciate knowing of people's experience with this medicine.

dimdinia,
30 to 40 % of zoledronic acid patients experience an accute phase response. Medical literature describes it an intense flu lasting for 3 to 4 days. Patient reporting indicates that it can last much longer.
The md who ran the clinical trials offers this advice.
"I am an osteoporosis expert, and have treated many patients with IV zoledronic acid. I have also played a key role in the development of Fosamax, oral and IV Boniva, so I know a lot more about bisphosphonates than most physicians. There are 3 things I routinely do when I treat patients with IV zoledronic that not all physicians understand. First, I order the infusion to dilute the 5 mg of zoledronic acid (which comes in 100 mL of D5W) into 500 mL of NS (normal saline), thereby diluting the drug from 5 mg% to 0.8 mg%. Then I order it to be administrated over 60 minutes, instead of 15 minutes. Giving an N-BP more dilute and more slowly makes it even safety for the kidneys. The 3rd thing I always do is order the infusion nurses to administer 650 mg of acetaminophen to the patient during the infusion, and I tell the patient to take at home the same dose of acetaminophen (two regular strength Tylenols) 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 with breakfast the 2nd morning after the infusion. These 8 doses total of acetaminophen reduce the chance of a symptomatic APR from 20-30% to < 1%.The other thing to consider is that in most patients, a 5 mg infusion of zoledronic acid will control the rate of bone turnover for at least 24 months, so most of my patients do not get annual infusions."
Zometa is marketed for cancer. Reclast is marketed for osteoporosis. Same drug zoledronic acid. Zometa is 4mg. Reclast 5mg even though they know that 4 mg is equally effective as 5mg for osteoporosis.
If you can get Zometa it would be better than Reclast because of less unnecessary exposure. You might print the above advice and give it to your prescribing physician so that they can direct the infusion center.
Some people don't have adverse effect.
Best wishes

As I pointed out in my post, zoledronic acid is used for many different medical conditions. I would assume this means different dosages at different intervals interacting with other medications and other pre-existing conditions. This advice is for those using it strictly for osteoporosis (in my case osteopenia) and only because I'm on an aromatase inhibitor which can cause bone loss. My hospital is an NCI Designated Cancer Center of which there are only 72 in 36 states. In this group it is a Comprehensive Cancer Center of which there are only 57. I don't think I need to share anything with them. But thanks for your interest.

@dimdinia I go to a top hospital center and shared what @gently sent as protocol for IV Reclast. I am also printing it out and bringing it with me. I was on an aromatase inhibitor a few years back, for 5 years and also have kidney issues so I am doing a 20% dose of Reclast so the instructions will need to be adjusted. I appreciated the info since neither my nephrologist nor endo had a protocol for this that they shared. They are relying on nurses on site. My endo has ordered IV and we'll see if that order matches what @gently posted.

dimdinia, it only that if you want a long infusion or a diluted infusion the infusion center has to be prepared. Of course, you don't have to share any information with them. You'll get standard care and you'll be fine.
The doctor who recommends this treatment protocol is an endocrinologist. You'd find that the cancer center unfamiliar with this method.
But anyway you are on the right track with tylenol.

I know you don't mean to be offensive but I'm not dimdinia. It's DLMDINIA as in DLMD IN IA. It's my oncologist recommending this, not an endocrinologist. I will be discussing it with my dentist next week. If she doesn't sign off on Zometa, the point will be moot. As I will need to contact my oncologist afterwards to set up an appointment I can certainly throw it out there at that time. It won't be happening until December. I did notice that you have not provided a link to substantiate this idea, and the typos are troubling. And how are you so sure what my comprehensive cancer center does or does not know? Until then, be sure I'll take your advice under consideration.

Hi
Wow Wish I would have read this prior to my last infusion for weeks. They did it over 30 minutes with saline.I did the tylenol and Is a hydrating drink The day before and the day of and the day after I started feeling like c*** 3 days after the infusion.It's been four weeks and i'm still bad. I am going back to my physician tomorrow.

Wow is right! What a contentious conversation. My husband has this medicine every three months due to multiple myeloma. This is a switch from the bone strengthener he received for two years previously. He does get a little achy with it for a day or two, Tylenol seems to help. Also he makes sure his calcium and, vit D3 are up to snuff. His amazing Mayo doctor said that will head off a lot of issues with this drug. Anyone else have any tips?

Super helpful! THANK YOU!!!!
Do you know the name of the MD who ran the trials? If I have Reclast or Zometa as a follow-up to Evenity, I want to share this with my specialist, and have them follow the instructions. I bet I'll be asked who the doctor is.

I keep seeing references to taking Tylenol; a drug I consider an expensive placebo. I would want something that would really help.
