I have had glaucoma for over 10 years- I’m 40 years of age.
I read about b3 being part of a trial and showed some positive results so I thought I’d give it a go.
This is my story:
I started taking 500mg nicotinamide in February 2022 (1 a day).
By spring 23’ I noticed I was struggling to fully empty my bladder in the evening (it may have started earlier but it wasn’t something I paid attention on).
In august 23’ I upped the nicotinamide dosage to 3000mg per day, taking 6 capsules throughout the day.
after two weeks I noticed that I was having urges to pass urine a little more frequently, however, soon after I went into urine retention, I hadn’t passed urine for over 30 hrs and had to have a catheter fitted.
bloods/scans all came back fine.
The doctors at moorfields, the vitamin manufacturer have never heard of a reaction like this.
anyone else experienced a bad reaction? My advice, if you take this for glaucoma, simply, DONT!
Just to continue:
As the doctors couldn’t find any link, after a month or so,I restarted taking nicotinamide, 3000mg however I was more accurate on the timing. Again, after two weeks, I noticed an urge to pass urine, that was followed by great difficulty in passing urine at all, which lasted for 6/8 weeks- while I didn’t go into full retention, every time i went, I had to strain sitting. Even with my bladder feeling almost empty I still felt I needed to go. It was horrendous.
I stopped taking nicotinamide for over a month, and in February this year, restarted, taking a dosage of 500mg-1000mg a day- after only four days, noticed an urge to pee even after I had done so, for a further 2 weeks, difficulty passing urine.
don’t know if it’s to do with the effect of the bladder, or the effect it has on the brain. But clearly, it doesn’t suit everybody.
