What is the best treatment for seborrheic dermatitis and rosacea on the face?

I changed dermatologists,as i have been having no improvement in my skin. She told me i have seborrheic dermatitis as well as rosacea. Protopic has been prescribed for the seb derm but i am apprehensive about using this as it has very bad side affects. What is the best treatment i should start? Would nizoral shampoo work on the face? I am so sad now as nothing is working for me, and i have had this flare for five months now.I have seen two dermatologists and had no results.
