What this medicine is used for

The name of your medicine is Chemmart Cefaclor CD tablets. It contains the active ingredient cefaclor (as cefaclor monohydrate).

  • bladder (lower urinary tract)
  • skin

How it works

Cefaclor is an antibiotic which belongs to a group called cephalosporins. These are closely related to penicillins.

It works by killing the bacteria causing your infection or by stopping its growth.

It will not work against infections caused by viruses such as colds or the flu.

There is no evidence that this medicine is addictive.
