Strepsils Lozenges relieve sore throat symptoms caused by bacteria and virus. It has dual action as it combines two effective antiseptics (2,4-Dichlorobenzyl alcohol 1.2mg, Amylmetacresol 0.6mg) with Levomenthol, which provides a mild local anaesthetic action on the throat and also relieving symptoms of cough. Strepsils Lozenges start to get to work immediately to soothe the throat. It provides fast acting relief for up to 2 hours to soothe sore throats back into shape. Unlike non-medicated throat sweets, Strepsils contain medicine that keep on working long after the lozenge has gone.
