Mucinex (guaifenesin) D: Two tablets with the Pseudoephedrine will make you feel a little jumpy or may make the heart beat a little more than normal. The Mucinex (guaifenesin) by itself will only cause a headache or a stomach ache. Feel better.

Certainly may: Firstly, do you have any medical conditions? Do you have hypertension or cardiac disease? You may experience cardiac changes or cardiovascular changes. Please contact your md if needed.
