Can I give my 3 month old son clobetasol propionate cream. 05% for seborrheic dermatitis on his head and behind his ears?

The answer is NO! Your 3 months old does not need a high potency steroid to cure his seborrheic dermatitis! there are a lot of cheaper and safer creams, ointments, scripts that are very effective.Dermasmoothe oil is a favorite script. Please discuss this w your pediatrician. Never use someone else's script without talking to your pediatrician first. Safety issues are a concern for little ones.
Clobrtasol. No, you cannot because clobetasol is a class one steroid and too strong for your child. You can try otc Cortaid or cortisone 10. If that is not helpful there is prescription Cloderm or locoid (hydrocortisone butyrate).
