Should be ok: Theraflu usually contains phenylephrine which has a short half life. Could use saudafed which has a long half life. A word of caution though as decongestants can increase your heart rate and blood pressure so consult your doctor if u think u may have a heart condition or glaucoma

Theraflu: Always read directions. Both should not be taken at the same time, however it is likely ok to take Sudafed if you have passed the time for the next scheduled dose of Theraflu. Choose one or the other to treat your symptoms.
