Should I take amoxicillin for salmonella?

Unless in blood. Unless the salmonella is in the bloodstream or severe enough to require admission to a hospital, antibiotics will not help. May make the illness last longer.
No. It's not likely to help. I would see your doctor to get a proper prescription and confirm the diagnosis of salmonella.
