A couple of years ago I had an allergic reaction to Cephalexin. Sudden flushed skin, felt warm, swollen throat, difficulty breathing, vomiting, etc.
Luckily I haven't needed to take antibiotics since then.
Now I may have to take Amoxicillin.

Is it common to have an allergic reaction to Amoxicillin if you had one with Cephalexin?

I could also take Clindamycin, but it is stronger so I would like to avoid it.
