Dear Mr Divir
you are very correct , it was drug used for Immune suppression. But topical preparation ( skin ointment) can be used for Atopic Dermatitis
( It is a type of allergic dermatitis
). Better reconfirm with your treating doctor , if necessary you can take a Dermatologist
opinion also in this regard. But while applying there should not be broken skin , it may get absorbed and systemic side effects may be more. treatment with this topical drug should not be more than 6 weeks.
Do not get panic , this topical preparation may not cause immune suppression .
