can you take mucinex d and tylenol sinus at the same time?
Tylenol sinus is not an antihistamine. An antihistamine blocks the release of histamine from mast cells which is what allergens like pollen do. Histamine chemicals dilates blood vessels and causes more fluid build up as a result - i.e. the "itchy runny nose of allergies". Mucinex D contains not just the chemical that thins mucus but also a decongestant similar to that in Tylenol sinus (the "sinus" refers to the decongestant not the Tylenol which is a fever and pain reducer). Tylenol sinus contains a decongestant that shrinks blood vessels in the nose leading to less fluid in the nose. Mucinex D is a medicine that thins mucus so it runs out more easily and doesn't therefore sit there and stuff you up so much, as well as containing a similar decongestant. It works on all mucus in the nose and chest. Mucinex D also has a decongestant in it that is similar to the one in Tylenol sinus. Do NOT use them together or you are getting a double dose that may cause heart trouble. You can use PLAIN mucinex (NO D) with tylenol sinus and that is safe.
