Please do not take any more pseudoephedrine. 240mg is the maximum daily dose of this drug. If you have high blood pressure, this is a dangerous drug and should be avoided. A fast, irregular, pounding heartbeat, mental or mood changes like anxiety, confusion, restlessness, shaking, difficulty urinating, as well as swelling, difficulty breathing, itching all need immediate evaluation.

you are correct, sudafed is in mucinex (guaifenesin) d. You may feel a bit jittery or have an increase in your heart rate today. You also may have a hard time falling asleep until it wears off. I would not take both in the future.
