@suzict Yes! omeprazole is one of the medications that is specifically warned about. As I said, I had several conversations with my cardiologist and my Camzyos REMS program nurse-case-manager. I'm not sure whether it was due to a relatively small dosage of omeprazole, or if the effects of omeprazole had maybe been found to be not as significant, or if taking omeprazole in the morning and camzyos at night, or all of the above, or none of the above (that's way above my pay grade to actually understand), the advice I got was to go ahead with the omeprazole/camzyos and to watch for anything. After about a year and a half, I've had no ill effects whatsoever. Hoping it continues like that, but if not I'll fight to keep camzyos and change anything else that needs changing.
