The Antibiotic Cedax is an original medication that are quite expensive since it's a 3rd generation Cephalosporin. I don't know the actual price but you can try to ask in some pharmacy. The rest are cheap medication.

It's better you work out how much you can bought these medication outside and add doctor's consultation fee and MC's price before decide if it is overcharge or not.

The best? It depends on the bacterial susceptibility. I do believe it is one of the strongest available antibiotic available orally.
The key is how much is one tablet Cedax 400mg cost? It may cost more than half of your RM 238 medication fee.

LOL..Cravit is also another expensive antibiotics, but from the picture it doesn't look like you were given Cravit, or at least not original Levofloxacin.
