It was so easy when I was "normal" whenever I got a cold and cough, I could just take some cough syrup, or decongestant. That was so long ago. I use to take some Nyquil at night, fall asleep and wake up the next morning and feel better. Not completely well, but better.
Since Crohn's, I haven't been able to do anything like that. Nyquil is now completely out of the question. If I take it, it goes right through me and makes for one hell of a "messy" night, not to mention the frequent hourly runs to the toilet. Sometimes even causing abdominal discomfort. So, what does one do when you catch a cold and have Crohn's..?? For me, just about nothing.
I did discover that the majority of cold medicines, and there are hundreds, contain the same medicine as a regular, or extra strength Tylenol. The active ingredient is the same, so why spend the extra money on something you already have in the medicine cabinet. This is what I take now and it seems to work nicely. Another thing I discovered since my Remicade treatments, Nyquil doesn't affect me like it use to. I can now take it and not have discomfort, only have to go to the bathroom a few times in the night and have only minimal accidents.
Medicine, like food and drink, for Crohn's is trial and error.
