With regards to taking the Singulair
and antihistamine together, I can understand your hesitancy. I know that
Singulair is not an antihistamine. My son does take antihistamines with the Singulair when he's been around furry creatures, but I am not thrilled about it. It may just get you through until the Singulair shows its full clinical effect, which I think usually is two weeks or so.
In the meantime, to calm your skin, perhaps you could try an oatmeal bath.
