I took Guaifenex for the first time yesterday, and I might add for the last time yesterday. My blood pressure rose quickly, the Systolic rose 40 points and the Diastolic rose 30 points and my resting pulse rate raised over 40 bbm. When at the doctor in the same morning, both blood pressure and pulse were normal. I have never before had this type of reaction to any medication. My night sleep of 2am - 4am will not help me get better, no matter how "wonderful" of a decongestant this stuff is. It took two doses for this reaction to hit me. I am sure that this may not be the normal reaction - but if you get it watch out, because it is very scary.
