What Cephatrust Capsules are used for

The name of your medicine is Cephatrust Capsules. It contains the active ingredient cephalexin monohydrate.

Cephalexin is used to treat infections in different parts of the body caused by bacteria. Cephalexin can be used to treat infections of the:

  • respiratory tract (throat, tonsils, chest and lungs)
  • nose (sinusitis)
  • ears (otitis media)
  • skin and soft tissue
  • kidneys and bladder (genitourinary tract)

Cephalexin belongs to a group of medicines called cephalosporins. These antibiotics work by killing the bacteria that are causing your infection.

This medicine is available only with a doctor's prescription.
