Owww kumihimo,
I can't help you with 'acid reflux' as a side effect..... but, I might be able to help you with the acid reflux..... I took Gavison by the bucket load, when out took Zantac tablets and then moved on to strawberry flavoured Gavison tablets.... virtually one after the other. If I bent down it would trigger it, I could only lie on my left side in bed... as soon as I would turn over onto my right side it started off straight away. I had this for some 4 years I think.....
Then I get a lung infection, I breathed in a 'crumb' from a piece of toast, I went to sneeze, took breath in and the crumb went 'down the wrong way' as we say. A few days later I have a mild pain in my back - over the lung area. I had a triage phone call with my doctor how said I had got 'bacterial pneumonia' 
and prescribed me some antibiotics. I have had antibiotics before but not on a regular basis.
It was s 5 days course of antibiotics, I start taking them.... just before I finish the course, I phone Doctor as pain still there, not as bad, but still there. I didn't want to 'stop' and then 're-start' - it was at the time when they saying too many antibiotics are no good for you and to finish course etc. Doctor gave me 2 or 3 extra days - and during this time the pain went......
Now then... what I noticed was I think it was either 2 or 3 days in to starting antibiotics my heartburn had 'stopped' completely stopped!!!
I was shocked, I didn't know what had happened or why. I looked the antibiotic up "Clindamycin" and it said.... I had a Doctors appointment few days, so when I was there I told the Doctor, I said, I couldn't believe it but this antibiotic had stopped my heartburn, I had it for years, taking Gavison by the bucket load... he replied.... that this antibiotic although it can irritate the throat (I never experienced this) it can kill a germ off that many people have in their stomachs that 'caused heartburn/acid reflux'....
The germ that can lie dormant even from birth is called 'Helicobacter pylori' many situations can trigger its onset.
I remembered the name by thinking about 'helicopter' 
- I then looked up 'Helicobacter'
I really hope this helps xx
Hi and many thanks for that. One of the reasons I was due to have a scope was to look for “helicopter’. Have to give up PPIs for 2 weeks before 
. Doctor in desperation did treat me for that some years ago without a scope but it didn’t seem to do anything.
I first started with acid 15 years ago when I developed a heart arrhythmia and standard practise was to take aspirin. Aspirin did it for me even with the enteric coated ones. That was stopped about 10 years ago but the damage was done. I managed for years quite happily on a low ppi. Age is a factor and over the years it became a little more frequent and had to up the PPI. Then BC 3 years ago (tomorrow) I started Anastrazole and the acid began having a ball last 18 months or so. Last couple of months as I said before the acid is 24/7 and having an orgy., hence now wondering if brands of Anastrazole can have that one effect.
Thank you for replying
