I'm having a little sinus trouble do to the change in weather and I was wondering if taking an off brand of dayquil would effect my bc pills like antibiotics do? If it helps the 3 main ingredients (I guess that's what you would call them) are Acetaminophen, Dextromethorphan, and Pseudoephedrine. Thanks in advance, [Amanda]
i honestly don't know, but i would advise possibly calling your doctor or a pharmacist, someone who has a better knowledge of that particular brand of cough medication, OR contact the company (through a website or phone number). I would also advise reading through the company's FAQ on their website, which might answer your question.
