Also I used the cream Ketoconazole 2% which I use on my face and I hear it's a bad interactive drug to use with the spray.. Is this safe? I have been using the spray for about 5 weeks now. however I'm about to start using the cream again for seboreaha (sorry about my spelling) I use the spray because I use it with a C-Pep device.. I have sleep Apnea, and need the C-pep to get sleep..My nose get's stuffed without the spray.. Any long term side effects from the spray?
