Ampoxin 500 mg (ampicillin + cloxacillin) dosage is not the same for everyone. It varies depending on the type and severity of infection (such as respiratory, urinary tract, skin, dental, or ENT infections), age and body weight (adult vs. child), kidney or liver function, and the individual’s response to treatment. While it is usually taken multiple times a day before meals, the exact daily dose and duration should always be decided by the doctor, as dose adjustments may be required in certain conditions. Therefore, Ampoxin 500 mg should be taken strictly in the dose and duration prescribed by your physician and not adjusted on your own.
