Lupron and Zytiga side effects
In July we learned my husband has BCR 1 year post prostatectomy. Imaging confirmed 2 small tumors in the prostate bed. We're so surprised given great surgical outcome; cancer contained and surgical margins clear. But, here we are.
Decision to do 18-24 months Lupron injections along with Zytiga/prednisone. First injection was 3 1/2 weeks ago with Zytiga starting a few days later. Until yesterday he was side effect free, none. Then awake all night the last 2 nights. Freezing cold, then hot. Then joint pain. Slept all day yesterday. Now still incredibly tired and sleeping again. The nurses said the symptoms often kick in at the 1 month mark. Question, do these last the entire time on the medication? Or will they diminish? In the next week or so he'll start 20 days of radiation which we know will make him tired. He's not sure he can do this. The good thing is the PSA done on Monday dropped to 0.04 from .25 a month ago. Thanks for any advice.

Zytiga reduces the amount of cortisol in your body, prednisone, offset that. If you don’t get enough prednisone to offset the cortisol reduction, then you get a lot of fatigue. I was at a prostate cancer seminar a couple of months ago where a doctor talked about his prostate cancer. he was having terrible fatigue problems so he increased his prednisone from 5 mg to 7 1/2mg and that resolved his problem with fatigue. I’ve been working with someone who would get out of bed and need to go back to sleep for three more hours because the fatigue was so bad. I asked him to talk to his oncologist about increasing his prednisone. He was told to increased it from 5 mg to 10 mg a day. It made a major difference in his fatigue. Some doctors recommend 10 mg as the initial dosage. Be aware that the drugs can also cause diabetes. Keep track of your A1c or fasting blood sugar to make sure you don’t have a problem with becoming prediabetic.
I had seven weeks of radiation and never had any problem with fatigue from it. Results will vary, some people do feel fatigue. I was on Lupron for 7 years so I got to “enjoy” all the issues it causes.
One solution to the fatigue is exercise. Get out there and walk at least a couple of miles a day. If you can do some weightlifting or at least exercises that involve weights that really helps and also offsets the muscle deterioration caused by Lupron. Those two things seem to help people the most to relieve the fatigue issue.
Don’t be surprised if Lupron causes you to get a belly or a larger belly, if you can weigh yourself every day and base what you weigh on what you eat it can reduce that belly fat but it occurs a little due to stomach muscle loss. Doing a lot of sit ups might also offset some of the belly fat issues.
As for hot flashes, I had severe hot flashes for the first year on Lupron. As a hot flash was hitting I would feel a lot of fatigue. After a year, my oncologist prescribed a depo-provera shot every three months and it really stopped those hot flashes on Lupron. There are other hormones that can do this, speak to your doctor.
I know one person that says eating tofu every day really controlled his hot flashes, another person in this forum said the same thing. Can’t hurt to try it.
Another thing you will notice after being on the Lupron for a while is brain fog. If you were going to ask a question and all of a sudden you forgot the details, names don’t come to you, you may remember all the facts about something, but can’t remember the names or other involved details. It can be frustrating.
Just a number of things to be aware of when starting these drugs.
In my experience with the same medications the hot flashes continue and fatigue comes and goes. One thing I have noticed lately is a fast beating heart that comes from nowhere (seemingly). I am having it checked by a cardiologist.
My hunch is his body is adjusting to the shock of the medicine. Perhaps it will lessen, as it did with me..
Best Regards
Zytiga causes a lot of heart issues. I’m on three different blood pressure medication‘s after being on Zytiga for 2 1/2 years. I never had blood pressure problems before Zytiga.
I started having a high pulse issue about a year ago. Just walking from the bedroom to the bathroom, 10 paces, would get my heart rate up to 120. I asked my cardiologist to switch one of the drugs I was taking to metoprolol and the heart rate issues stopped. I go to the gym and have a personal trainer work with me and when I get really going and feel my pulse should be at a very high rate It’s at 108. I found out about metoprolol from a friend who is a retired cardiologist.
Terrific info, thank you.
