Afternoon all, so I've been on sertraline since end December I started with 50mg in brand name accord, however I'm now up to 75mg (Dr wants me on 100 but I'm pacing) I've been on 75 for 3 weeks. Monday I got another prescription and the the box is different and it says crescent. I have started to feel yuk feeling like I've had a pint of milk and it's not digested. Is this normal? Could a brand change make a difference. I'm worried because I'm haven stool test done for chronic diareah and I don't want it to be worse. Some reassurance and advice would be great.
