Starting Orgovyx - how long for side effects to occur?

Posted by daveinflorida @daveinflorida, Feb 17, 2025

I've been taking Orgovyx for about 3 weeks and so far have zero side effects: no hot flashes, no fatigue or tiredness, no weight gain, no ED, nothing. I'm not complaining, but I'm on pins and needles waiting for stuff to start.

For background, I am in good shape and very active, I've been running for years and run 4-5 days a week, 30 - 35 miles, and also resistance train 2-3 days/week. I have no idea if that's what's doing it, but I'd be doing it anyway.

I think you got a little bit carried away here.

Genital shrinkage up to 75%, also permanent is just Not how people have experienced it. The shrinkage is not permanent and is not 75%. It’s minimal maybe a half inch average If you have surgery.

Possible heart failure, Well, anything is possible, but after 8 years of being on ADT And hearing from dozens of people that have had it, not one of them had heart failure and died. When I was on Zytiga, I had afib events, which are no fun, Never had it from ADT. Zytiga not ADT also gave me high blood pressure, For which I have to take three pills every day, But ADT has not made it any worse over these years. My blood pressure is actually pretty low normal.

Libido definitely Comes back for almost all the men on ADT once they’ve been off it for a while. There are a few men, Usually older men. Who testosterone doesn’t come back which also results in the loss of libido. At 77 I stopped ADT for seven months, My testosterone started coming back pretty quickly even though I had been on ADT for 7 years. My oncologist and I both figured it would never come back. Had to go back on Orgovyx Because of a genetic problem that requires I keep my testosterone low.

Six years after I started ADT I found I could not get off the floor without pulling myself up on something. I then started going to the gym three days a week. Yes, my muscles deteriorated over time but not that much that I noticed it was a problem for six years. Four months after going to the gym, I was able to get off the floor without pulling myself up. My muscle loss wasn’t all that rapid.

@jeffmarc Thank you for this. Kharlan was very negative. I'm starting ADT with orgovyx tomorrow. Radiation in a couple months(26 sessions) This will affect my wife and I because we will have to move to the area during the week because we don't live close to the hospital. I have to admit that I'm scared because my PCa has spread to my rectal wall(locally advanced) is what they call it I think. My doctors at Stanford are optimistic but I'm still scared how my life may change. I'm 67 and very active. I walk 3 miles every day with my dog and walk 9 holes of golf twice a week. I resistance train with bands and light weights 4 times a week and spend 30 minutes on an elliptical 4/5 times a week. No kids no grandkids so lots of time to do all of this. We have travel plans that I plan on doing. I hope I'm doing enough to go in as healthy as possible. Thank you for your positive response. Any advice would be appreciated.

My case is different because I was simultaneously on Abiraterone with the Orgovyx. So I don’t know which, but I had hot flashes starting the end of week 2. I completed the 6 mos intensive treatment with radiation in the middle, January 30. Flashes continued until (I hope) about two days ago. But they were becoming less noticeable.

My understanding based on the continuous volley of questions I fired in a friendly, curious way to the NP, nurses, Docs and staff is that symptoms track to your Testosterone level. When it gets toward zero, your metabolic functions are messed up. Sounds like yo are not there yet. Like others who commented here, exercise is critical to surviving better. Also what you eat, I found myself more sensitive to Carbs and had to watch that.

Without its Testosterone, the body says “what the heck, where is my Testosterone, you’re screwing with my metabolism and hormones, dude.” What I noticed were the flashes, fatigue, intermittent cognitive slowness, and of course, the obvious: Doctors refer to ADT sometimes as “chemical castration,” and I wondered whether my attitude, presence and interests in the opposite sex would change. They absolutely did not. I was and am in recovery, still totally Male in my thoughts and interests. But ability to do anything about it? Zip. Nada. Zero. Limp city. I may write about it at some point. Along the way since I had to have the intensive and definitive radiation for high risk, I got gold pellets placed around the offending gland in a procedure that required, among other things, for me to be in stirrups. LOL. That and the essentially menopause-like effects, including some emotional volatility which for me was being short tempered. It all gained me terrific insight to the opposite sex. I put a box fan near the bed pointed at me on low, because the flashes mostly bothered me at night. Now in recovery mode, (they tell you it takes a couple months or so) some of the short tempered-ness and stuff is on replay. But whatever.

But the capper was the stirrup experience, feet up and wide, buck naked below the waist, a couple of pretty nurses and a tech down there, a higher level tech at my side chatting with me about music preferences. How did I, as an older man who grew up working as a farm hand, who had a family of kids and now grandkids, end up in stirrups with those helpful onlookers? It is a comedy. Having got through it, I learned a LOT.

Bottom line, I believe it tracks to Testosterone level and every man is different both side effects as well as how long things take. It’s very humorous if you let yourself look at it, and a fascinating, occasionally intense, educational experience. Hang in there.

@steveduke Had my stirrup experience with my most recent biopsy. Quite humbling and painful

@10sweatherman
Can you get One of the rental spacers like SpaceOAR, Barrigel, or BioProtect. I can allow them to radiate the prostate without getting the rectum.

Some people are able to have the radiation done somewhere else using the instructions from the doctor you are going to. Have you looked into this option at all?

Some groups like the American Cancer Society have free lodging for people getting cancer treatment.

Radiation usually only causes issues that last for a few months. Going away is in your future. I had 40 sessions 12 years ago and had no side effects for a few years. Results vary.

@10sweatherman No need to be scared but be concerned and take proper counter measures. Keep up with the exercise. It reduces fatigue etc. from the ADT. Orgovyx should reduce testosterone to castrate levels in less than 2 weeks. Side effects vary. I had none other than about 50% testicle shrinkage (use it or lose it). Took 1 year+ to recover after ADT ended. No significant loss of muscle or bone (used calcium citrate supplements). Sex not the same (dry) and with G8 this will almost certainly be a side effect of your RT. May want to use 5mg Cialis to reduce the probability of fibrosis especially if ADT will be long term. The cancer at rectal wall is an issue. See if a spacer can be used since the radiation dose will need to go closer to the rectum to get that treated increasing probability of proctitis as a radiation side effect (ask your RO about the planned dose). See if you have the option of a shorter course of doublet therapy (ADT + ARPI such as Nubeqa) vs. longer ADT only.

@10sweatherman Keep making travel plans! I'm 4 months post completing 18 months of Orgovyx and had 44 IMRT treatments for cancer in the prostate and nearby lymph nodes. Keep exercising, especially the resistance training, because ADT is known to cause muscle mass loss. About the question of side effects, I don't know. I had all of them in varying degrees with fatigue being the worst, but they seemed to have lessened a bit after a year of treatment. All the best!

Never got a DEXA and when asked 3 doctors ALL said it wasn’t needed even with a course of 18 months on ADT!!

And what if your cancer comes right back and you need to stay on ADT? In that case, you really do want that DEXA scan.

The goods news is the radiation treatment kills the cancer. As my oncologist stated, there is no such thing as remission. During the treatments you will likely experience some tiredness and fatigue. I started orgovyx and abiraterone/prednisone roughly the same time as SBRT (radiation) treatments. In all I had 30 treatments to address cancer in my prostate and seminal vesicles.
My experience initially was fatique, loss of labido, light periodic hot flashes, ED, very emotional and depression. The latter was likely due to adjusting to my new normal. The best way to counter the side effects is exactly what you are doing. I've been exercising (weight lifting, bike riding etc.) and it's helped tremendously.
It's an adjustment, but if like me you have a supportive wife, the overall quality of life remains. It gave me a different perspective on life and I'm living it to the fullest. You'll do well, consider it a speed bump.

What did your oncologist call it when people had Their PSA stay stable for many years after treatment. I know people that have gone 10, 15, 20 years without Prostate cancer coming back. And then, after those many years, it came back. Were they not in remission?

I’m in a three your remission. I’ve had prostate cancer for 17 years And had four reoccurrences, but while I’ve been on Orgovyx and Nubeqa i’ve been undetectable for 35 months. If it’s not a remission, what is it?

Being on Orgovyx and abiraterone You are pretty much guaranteed to have fatigue. The radiation itself doesn’t cause much more compared to what the drugs do. I worked with a couple of people that were extremely tired on abiraterone, I had them contact their doctor and get 10 mg of prednisone instead of 5 mg and that made a major difference. Both doses are standard of care. I had 40 sessions of radiation and had no fatigue at all. They did put me on ADT before doing the radiation, and for some reason, I had no side effects. When I started it back up again 2 1/2 years later, the side effects were unrelenting.
