How Benylin 4 Flu Works
Benylin 4 Flu Tablets contain three complementary ingredients that act together to relieve cold and flu symptoms:

Paracetamol works by reducing pain signals and lowering body temperature.
-
Pseudoephedrine narrows swollen nasal blood vessels, clearing nasal passages and reducing sinus pressure.
-
Diphenhydramine blocks histamine receptors to reduce sneezing, watery eyes, and nasal discharge – helping you rest and recover.
