Is vomitting a symptom of strep throat or is it a drug allergy reaction?

So I went to the doctor today because I have strep throat and he gave me antibiotics called Curam. I vomitted. I have been having strep throat for 5 days, and this is the first time.
Am I possibly allergic to Curam or is this to be expected when you have strep throat?
I plan to go to the doctor again.

I took it after my food, once in the morning and once in the evening. However, I only vomitted in the evening and I felt fine after taking the pill in the morning.

i had strep throat and i vomited when i took the recomended doses of the medications at the same time, like it was too much for my system or soemthing. staggering them may help, eating something to have something on our stomach when you take meds is also a good idea
