Effexor and kidney stones
My son has been on Effexor for 2-3 years and during that time has developed calcium kidney stones so severe he has lithotripsys every 8 weeks. None if his doctors have ever linked the two but we have just read an FDA report that says up to 26% of males his age will develop kidney stones on Effexor. Please let me kniw your experiences, esoecially if ceasing the drug also stopped the formation of stones.

@wendyw - Sounds like you are doing everything you absolutely can. You are a good mom!
@wendyw - I disagree. Some parents, especially with older children, keep their distance. Give yourself a pat on the back...AND DON'T GIVE UP!
@kdubois , @predictable , Do you have anything that you might be able to share with @wendyw about her sons experience with kidney stones?
Rosemary, after checking so many things we have accepted it seems Effexor is not known to cause kidney stones. Rather devastating as we were hoping for a reason and cure!
so what we are left with is he has medullary sponge kidney all his life but no symptoms until 3 years ago, and ulcerative colitis which developed when he was about 20 ( now 41). Both of these can cause kidney stones too.
With lithotripsy's every 8 weeks and severe pain in between we are desperate for answers. If anyone has ANY suggestions for stones, pain or cause please help. Thank you
Lynn I thought I had replied to you, sorry. Earlier this year he saw an endocrinologist who ruled out parathyroid issues. It was disapponing, he really wanted it to be this and treatable!

Hi Wendy. I live in New Zealand. My 19 year old son is on Enlafax and has had two excruciatingly painful kidney stones in three days. One has passed tonight and a CT scan has shown that there is another one moving and this will probably cause him huge pain at 3am when his painkilling shots wear off. He has multiple small stones in his left kidney. Having kidney stones at 19 is rare in our country. Something isn't right and I'll be in contact with you. I doubt that my son will be on this drug by the end of the week. Take care and sending you my best wishes.
Has he weaned off the effexor?
Hi @newzealandmum, Enlafax and Effexor are brand names for the drug venlafaxine (as you already know). A couple things that I've learned from discussion here on Connect.
1) Kidney calculus or kidney stones are a rare yet know side effect of venlafaxine
2) kidney stones can happen at any age. You might be interested in this video

2) Venlafaxine can have serious side effects if stopped abruptly. Work with your health provider to taper off the drug slowly if you wish to discontinue it. Here is a lengthy and informative discussion on Connect about tapering:

NewZealandMum, how long has your son been taking venlafaxine and at what dosage?
@wendyw i know this is late, but I had a large kidney stone after taking this medication for anxiety as well. I took it for around a year and got a 7 mm kidney stone that had to be removed in 2017. I was 27 at the time and I’m a female. I later found that kidney stones are a “rare” side effect of this med. It’s been 3 years and I haven’t had one since I stopped taking the medication. I strongly believe it was due to the medicine. I take “rare” side effects more seriously now as many people including me would never think to connect the side effects to the drug. Therefore most of the time it isn’t noted or recorded by doctors.
Side note: Lots of migraine medication/seizure medication causes kidney stones too. My neurologist prescribed me some after I told her I had a stone before and was more prone to them and to not give me anything that could cause them. I read the info that came with the prescription When I got home and it said to “drink a lot of water because it could cause stones”. Make sure you do lots of research before you or him takes any more meds. It’s hard to trust anything these days.
