Cloxapen, also known as Cloxacillin, is a type of penicillin antibiotic used to treat a wide variety of bacterial infections. It works by stopping the growth of bacteria, effectively combating bacterial infections.

Cloxapen is specifically designed to treat bacterial infections and will not be effective against viral infections such as the common cold or flu.

Using antibiotics unnecessarily can lead to antibiotic resistance, where the medication becomes less effective against future infections.


  • Take Cloxapen capsules exactly as prescribed by your healthcare provider, including dosage, frequency, and duration of treatment.
  • Take Cloxapen capsules on an empty stomach, ideally 1 hour before or 2 hours after a meal for optimal absorption.
  • Take Cloxapen capsules at evenly spaced intervals throughout the day, typically at the same time(s) each day, to maintain consistent medication levels in your body.
  • Continue taking Cloxapen capsules for the entire prescribed duration, even if your symptoms improve after a few days. Stopping it early can allow the infection to return.
  • Tell your healthcare provider if your condition worsens or persists after using Cloxapen capsules for a while.


  • Don't take more or less medication than prescribed by your healthcare provider, or take it more frequently.
  • Don't eat with meals. Avoid taking Cloxapen capsules with meals, as food can interfere with absorption.
  • Don't skip doses. Try not to miss any doses. If you do miss a dose, take it as soon as you remember. However, if it is close to the time for the next dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose.
