Hi folks, Hope I'm posting in the right place, people here have been so kind & helpful to me before & I'm looking for more information & advice. I've been on oxycontin for pain for about 18 months, coming off for a year so far. In April my bloods started showing messed up immunoglobulin levels (IgA, IgG & IgM). They've stayed messed up since. Every time I get a tiny infection I have to go on antibiotics because my immune system can't deal with anything. I'm now losing my teeth . I'm on an urgent waiting list to see an immunologist. Does anyone here know what treatment is likely to be helpful (I've been told I need an immunoglobulin infusion, but that was only from a GP)? Once I'm off the oxycontin could my immune system sort itself? It will take me around 4 months to reduce the remainder (I was up to 210mg/day when I began reducing, am down to 60mg/day). That's not quick enough for my dentist who says my teeth can't wait another week. I read that OC can have bad effects on the immune system. I have health conditions anyway & this is just one more I don't need, but I'm guessing the OC is to blame. I'm guessing perhaps not too many people will have this sort of experience, but someone will & I'd be *very* grateful to hear any thoughts, advice, opinions, experiences. I might ask my hairdresser when I see him next. He's an ex heavy opiate user (he was on about as much as I was - I think that's a lot, right?) & I don't think it did his body any favours either, so he might have an idea, but I don't *think* he'll know immunology stuff. I could be wrong though, he might.
