Can you mix Sudafed and acrivastine?

It is probably not a good idea, since theraflu typically contains another decongestant known as "phenylephrine." Combining the two decongestants could have harmful effects on blood pressure since they both constrict blood vessels.

I wouldn't take sudafed with theraflu. I would opt to go with either sudafed and Tylenol if a pain reliever therapy is preferred, or just taking theraflu.

Ive found phenylephrine to be a pretty effective decongestant, especially in the theraflu formulation
