Interesting to see what everyone wrote. I was so sick with my cold
and had a fever, my usual sinusitis, real sore throat. Asked several
pharmacists that known over the years and trusted and all said I couldn’t
take any medicine other than mentol spray to nose. I always HAVE to
take stuff to clear my sinus’s with colds or I will have stuffy nose..
for ever! Finally talked to my endocrinologist and he laughed and
said I could take the 4hour lasting medicines. Therefore I took about
one a day to be moderate and whamo I got better soon! By far best
advice was as Jake said: ask your Dr.!!!
