Any tips for managing nausea while on hydroxychloroquine (Plaquenil)? I was just diagnosed with rheumatoid arthritis last week, and that's what I was prescribed, but I can't take ondansetron (Zofran) while on it because of potential interactions. I have IBS and other stomach issues and usually have to take Zofran about once a week or so. I'm going to ask my GI about alternatives but wanted to see if anyone else has run into this
