How to dose Dalacin C in my daughter (14 years old, 50 kg)?

When it comes to dosing, you should follow the information given to you by your doctor - the amount of antibiotic dose depends not only on body weight or age, but also on the type and severity of the infection, the sensitivity of the microorganism causing the infection and the general health of the patient.

Too little of an antibiotic can be ineffective and contribute to the development of bacterial resistance, while too much can be harmful and cause side effects.

If you are unable to contact the doctor who prescribed this antibiotic, you can use the teleconsultation:
