Guaifenesin for Cough "The doctor gave me a sample of this when I complained of congestion. I took two tablets, which may have been too much since I developed the runs. I'll try it again, but only one tablet. Or, I may just get Robitussin since the doctor said that Mucinex is a magnified version of Robitussin."

For Cough "I used guaifenesin for mucus relief with a cough. I drank a full bottle of water with it and 30 minutes later, ate supper. At 12:30, I woke up with vomiting and severe diarrhea. Blood pressure went sky high (from a normal low). Headache and dizziness. I couldn’t eat for 2 1/2 days because of the nausea. Blood pressure went back to normal after 24 hours. I have used other cold medicines, and every one would make me at least slightly nauseous. I didn’t know they all contained this ingredient. This seems to be abnormal for this medicine, so I think I may be allergic."

Guaifenesin for Cough "I highly recommend drinking large amounts of water with this medication. I was not aware to do so because it was nowhere to be found on the label, and it resulted in vomiting and the runs. After hours of this and speaking with a nurse, I was able to get it under control. Will not ever take again."
