Excellent question : Good for you by asking this question! Depending on which formulation of Dayquil, one has phenylephrine and another has pseudoephedrine. Both of these can elevate blood pressure and heart rate when combined with Vyvanse (lisdexamfetamine). Ask your healthcare provider as this may not be safe for you depending on your health history. It is always best to ask before taking over the counter medications with your meds.
