Stopping flomax/tamsulosin?

[Jpburns]

I've been taking Flowmax for several months, along with my Orgovyx, because of some hesitancy and feeling like not emptying my bladder fully. Not sure if it's doing anything about that. I go through periods of normalcy, followed by times where I have to pee often.

I'm thinking about stopping it, at least as an experiment, as I'm experiencing what may be side-effects, but things that also might be attributed to the Orgovyx. Mainly, I've noticed a sharp increase of hot flashes (with sweats) over the last few months. I know the ADT does this, but the increase has been noticeable and annoying. As a general rule, I like the idea of reducing the meds I'm taking, and maybe this will help. My urologist said I could try stopping the flowmax anytime I wanted to.

Has anyone else experienced this increase of hot flashes when taking both these meds? Or is this something "normal" after 13 months of Orgovyx?

Thanks in advance for your experiences.

I've been taking 2 Flomax every day. My symptoms have improved greatly. At my most recent Uro appt, I asked if I should reduce the dosage to 1 pill. He said no. The any side effects are minor and why stop as it's working to keep my urinary issues at bay. I haven't seen hot flashes as a possible side effect.

I just responded to another posting about the increasing hot flashes while on (and off) Orgovyx - please have a look.WRT Flowmax, I was on it since August 2024 and needed it, just as you described. I tried easing off it maybe 4 months ago but went back on it until Feb 2025 when my RO suggested skipping every other day for a week, and then stop. I skipped for 2 weeks and then stopped. Been fine without it.

I did see the hot flashes increase over time but that began a month or so after starting Orgovyx in February 2024, so before I began using Flowmax.

Jp, I had to start the Tam during RT, when my urethra went on the fritz. I started on two doses per day (plus ibuprofen). I noticed an increase in random dizziness which seemed to diminish over the month. My urethra recovered to where I needed only one daily dose. Then I added Abi/pred to my Org six weeks after my RT. Dizziness increased and was a problem making me determined to get off the Tam. It took a lot of patience in the bathroom, but I went cold turkey in Feb and have been off the Tam since and I’m glad for it. Of course, I upped my Abi dosage to the full 1000mg per day also in Feb (at the insistence of my new MO). SEs have really settled in—more brain fog, intermittent nausea, increased fatigue. My urethra is about 80% of where I was prior to RT, but I’m definitely glad to have left the Tamsulosin behind.

I was on Flomax (Tamsulosin) for awhile but, eventually, it caused me to have bradycardia. I've switched to Myrbetriq and that has worked well so far. Every once in a great while I will have one day where I have bladder spasms and an urge to pee throughout the day. When that happens I take one Hyoscyamine (0.125) sublingually and that shuts off the spasms almost immediately. Regarding hot flashes on Orgovyx, I did have those at first but they diminished quite a bit with time and with exercise.

you might want to try prazosine instead of flowmax

I so want to cut down the number of meds I'm taking. I'm 24 hours without flomax - think I'll see how it goes. But thanks.

This is anecdotal at best, but possibly of interest. I had SBRT a year ago. I have been on Orgovyx for 13 months, and was on Tamsulosin for about eight months. The hot flashed, muscle pain, and other side effects led me to stop taking it about five months ago. My flow of urine slowed a bit but my body felt lots better.

A week ago, I started using a penis pump. It seems to have loosened things up. I feel I have completely drained my bladder, all be it still a little slowly, while standing up. Previously I had to sit in order to achieve the right plumbing arrangement to go well.

Just one experience, and still in progress.
