Advice & Tips: No tummy problems at all with the mixture of drugs I am currently taking. There was a little period with the injected Fragmin stuff where I'd get acid for a couple of hours, but that's all done now. Actually, I've had acid problems in the past and swore by omeprazole, but ranitidine is just fine.
