Cholestyramine Side Effects
M30. Not diagnosed, but heavily suspected BAM. Had it since I was 16, but it was manageable until about 18 months ago, when even eating 10g of fat a meal would sometimes give me a lot of urgency (as little as 15 minutes). Gastro had me doing low FODMAP with no improvement on random flares. I was then given ondansetron, which solved general urgency as long as I stayed low fat, but gave me mild constipation and hand tremors. It suddenly clicked as I read about BAM and I asked my gastro to give me cholestyramine, to which he agreed and prescribed. I’ve been on it for about 6 months.
It got rid of my urgency, and I appear to be able to eat a fair bit of fat in a sitting without urgency now which is great. But when I first started, I had one small episode for a week where if I ate a regular amount of fat a sitting (15-25g) I got terrible, terrible gas. Lasted for hours every time I ate and smelled like pure sulphur. I asked my gastro about this and he passed it off as “gastritis”. I was discharged and have an open appointment if I want it.
Last couple of months, the gas has just not gone away. I’m back to feeling like a prisoner in my house, because I can’t be around people for 6 hours after I eat, which is basically 100% of the time. I typically tried to stay around 45g of fat per day and take 2x4g doses, one with lunch and one with dinner. If I eat a large amount of fat in one go, it’s definitely worse. I haven’t been brave enough for really high fat foods (lots of cheese, burgers etc) yet.
Has anyone else had these side effects? I could only find one post that mentioned it, but with little info. My gastro (and all other nhs contact for that matter) has felt very dismissive, so I want the confidence from other people’s experiences to know whether it’s worth taking that open appointment. I’ve been threatened with a sehcat test if I return. I’ve read people have a a better time with the pill?
