Thank you ma

First of all, you shouldn't self medicate. It is not advisable as most people tends to get it wrong eventually which increases the risk of complicating medical issues. The best, in most cases, is to visit an hospital and seek the expertise of medical professionals.

Secondly, calamine lotion is an antipruritic agent. This means it is only meant to alleviate the itchiness associated with the chicken pox rash. There are still other symptoms which won't be eradicated with the singular use of calamine lotion.

Antibiotics will be needed to stop the infection. If there is fever, paracetamol or ibuprofen will be fine too.

Nevertheless, remember to consult a professional before choosing an antibiotic.
