Post RP I'm on Bicalutamide 150mg and have been for the last 3 months and have just started RT to the prostate bed and lymph nodes nearby. One of the side effects I'm getting is nausea which I know is down to the RT but the nurses in RT seem a bit puzzled by this. So can you folks confirm is this just me or is this a known side effect of RT. The marginal fatigue I was feeling from the hormone treatment has increased with the RT to being quite lethargic, which I believe is not unusual. I will have to get nausea meds from my GP as I'm expecting it to be cumulative. I'm trying to be active and sometimes do the opposite of what my body is telling me which is to take it easy.

Not something that I noticed when I had 15 sessions of RT. Is it only during the treatment or does it persist?

Must admit that with 32 sessions of RT I didnt feel nauseous much at all, I had several effects from the HT I was on but seem to remember the RT affected bowel, bladder&fatigue and effects didnt start too soon after RT started.

I've noticed the extra fatigue and nausea from the start of RT which was earlier on this week so can only imagine it will continue but hopefully not accumulate over the next 3 weeks. Will definitely be looking at getting nausea medication.

The vast majority of men having RT sail through it but there have been a very small number who have been severely affected for some reason and a couple even having to stop the treatment. Seems sensible to see if you can get ssome suitable medication to deal with your nausea because it's best you continue if you can.

I'm on RT session 17 of 20 and haven't had any nausea, however I'm not on HT. May be its a combination of both that's affecting you as it does have a big impact on the body. Hope it passes quickly for you.
