Difflam Throat Spray (Benzydamine) contains the active ingredient, Benzydamine, which acts locally to stop pain and inflammation. Its design ensures that the powerful active ingredient is delivered straight to the point of pain, for fast, targeted pain relief. Benzydamine hydrochloride is a painkilling medicine used to relieve mild to moderate pain and inflammation in a particular area. It is most effective if applied directly to the area affected. Benzydamine also acts as a local anaesthetic, causing numbness and so pain relief at the site of application. Contains the same ingredients as Tantum Verde.
