Does Singulair need to be stopped prior to patch test application? Many dermatologists in our area are making this recommendation. I can't find any information re: Singulair in the true test patch test information. Please advise.
Thank you for your inquiry.
I am not aware of any effect that Singulair has on patch testing, and could find no reference to such an effect with a literature search.
Thank you again for your inquiry.
