That is both unnecessary and careless.

If he actually took a throat swab and confirmed the throat infection was caused by Streptococci bacteria (most common cause for bacterial throat infections), then the most simple brand of Penicillin would have sufficed. There is still no resistance among Streptococci to common Penicillin.

A broader spectrum antibiotic (like Cefadroxil) will only create further risk of resistance in the community and there is no advantage in this case but for the Drug company.

Cefadroxil could however be of choice with repeated or persistent throat infections (which I presume this was not the case?).

Besides, chances are (if the doc did not confirm with a throat swab), that the infection was caused by a virus - in which case antibiotics is of no use at all of course..
