It is very wise to read all labels, ingredients and continue to research because there are literally millions of arrows coming our way every single day. That is why I no longer take anything OTC unless it is clear of ingredients and states a lot of possible side effects. IOW - why would I take something for a headache or sinus IF that can cause dozens of side effects. I only have to deal with the headache or sinus and that will subside on its own. As for prescriptions - no thank you Doc.
