I have just started taking Gabapentin for my RLS and I’m suffering really bad acid reflux, to the point that it is difficult to eat or drink anything. Is this likely to be a side effect of Gabapentin (as it isn’t listed as a common side effect)?

Gabapentin & acid reflux

Just enter gabapentin and acid reflux into search engine and there are numerous people reporting it as a side effect. Also report it via Yellow Card report in UK or FDA adverse side effects in US because unless we report these side effects, they are not listed on the meds leaflet.Be wary about taking PPI gastric pills to counter the acid reflux as they worsen RLS for the majority.
Try taking a good probiotic like VSL or Symprove and try Gaviscon or magnesium based antacids, taking them 2 to 3 hours before the gabapentin as magnesium can affect gabapentin absorption.
thank you!
Hi Jools, I had to report back on something to you. I think probiotics do help with reflux/heartburn though as usual I doubted you. I’ve been taking Kimchi for months (4?) now and about a month ago noticed a dramatic drop in reflux/heartburn which I was completely certain was due to a moderate sized hiatal hernia, yet I now truly believe the gut microbiome is also somehow involved, but it may take 3 months to see any improvement. Zinc worked well, after the fact, but in no way ever prevented reflux.
The kimchi has done nothing for the RLS sadly, which is seemingly worse since I had Covid this past October - to the point I’ve been taking double and even triple the amount of iron. However, while I was taking berberine for about a month, the RLS seemed vastly improved, almost from day one, but the stuff really (really) slows down motility, so I stopped about three or four weeks ago and I never quite took it everyday anyways. Last night was the straw that broke…so I’m back on the berberine…at half the dose. And yes, I was even taking a stool softener and fiber to no avail. If I have to I will go in for the stronger stuff - Miralax. I want to get in a solid 3 months of berberine.
Sounds like you continue to do well which pleases me to no end. Xx
Same here but it seems to come and go.
I have also just started taking it and have noticed indigestion issues. I take lanzaprozole anyway so will need to look at suggested alternatives .
yes I already take Lanzaprozole too. I think I need to speak to my doctor if it persists; there’s no point in taking a drug if it solves one issue but causes another
I know but I'm goi.g to see how it's goes as if the gabapentin solving the RSL I will try a different solution for reflux I think
the problem is that mine is so severe, that I’m struggling to eat and drink at the moment. This is like nothing I have experienced before - actual pain in my throat, cough etc. I’ll give it a few more days to see if it settles down, then I’ll have to go back if necessary
thank you!
Apple cider vinegar (1tsp-1tbsp) in warm water before meals helps tremendously. I add 1 tsp lemon juice to make it more palatable, some don't.
It can be a side effect. Most antacids make RLS worse. A safe one to take is Gaviscon. Most side effects disappear after about a month.
thank you!
I too am having acid reflux after starting gabapentin for my RLS. The gabapentin (800mg tablet in the evening before bed) has really helped my RLS but the acid reflux started after about 6 weeks on the gabapentin. I will try Gaviscon and would like to know when you suggest taking it and at what dose. Also I like to stop eating after 3 pm (I’ve been restricting eating to an eight hour window 7am-3pm for a couple of years). Is it ok to take gabapentin on an empty stomach or could that be exacerbating the acid reflux? Thank you!
Ask your doctor on the dose and timing of gaviscon. You can take gabapentin on an empty stomach. Most people do. I doubt that taking it on an empty stomach would be exacerbating your acid reflux. If you are taking 800 mg all at one time though, you should divide the dose since it isn't well absorbed above 600 mg. Take 600 mg 1 to 2 hours before bedtime and 200 mg 2 hours before that. You may find you only need 700 mg as a result.
