Not everyone gets hot flashes, I had really strong ones The second time I had Lupron 2 1/2 years after the first time. They did tell you to start taking calcium twice a day as well as vitamin D? It is a sexual to keep your bones strong while you Are on ADT.

When I had my first 6 month shot of Lupron (same ingredients as Eligard) I didn’t have any side effects at all. It was given to me two months before I had radiation, similar to your situation.

Did they give you Casodex for two weeks before you started ADT? That really is mandatory since you get a testosterone Spike which makes things worse if you don’t get Casodex. If they didn’t give you that I would be a little suspicious about the place I was being treated, It is considered standard of care to do it.

Due to their different mechanisms of action. ADT which includes Orgovyx, Firmagon, Lupron, Eligard, Prostap, Camcevi, Lucrin, Zoladex, Trelstar, Pamorelin, and Decapeptyl can cause numerous side effects. Actually due to a lack of testosterone.
Hot flashes
Fatigue
Muscle deterioration
Bone weakening
Brain fog
Depression
Weight gain
Joint pain
Difficulty in breathing

Not all of these side effects occur to everyone on the drugs. Most of them are just things you have to be aware of and circumvent. I run on the track twice a day, 1 mile at least, to help prevent bone weakening, fatigue and muscle deterioration. I also go to the gym three days a week (usually) and spend an hour with all different types of weight exercises. One thing that happens is people get a beer belly from the muscle deterioration, I do a lot of sit-ups to offset that.

Some people get depression but it is not common. It is easily treatable, according to people that have reported it on here and on Online Meetings I have participated in. If he has that problem Come back and ask for help, Or see a psychiatrist about doing something to relieve the depression. Believe it or not doing exercises and running or walking can help relieve the anxiety and depression.`

Some people get no hot flashes at all. Others only have a few hot flashes and they are very minor. 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. Tofu does have properties similar to endocrine hormones but a lot weaker. Can’t hurt to try it. Seems they ate it daily.

According to a doctor that spoke to a recent webinar, many people on ADT should be taking bone straighteners if they are staying on ADT for an extended period or have become castrate resistant. I took Fosamax for six years and I’m now on Zometa. That along with calcium taken daily helps keep your bones strong. Ask your doctor about this.
