Strepsils is a line of lozenges manufactured by Reckitt Benckiser in Nottingham, United Kingdom. They come in a variety of flavours. As of 2010, it is the largest-selling sore throat product in the world.

Strepsils have been in production since 1958, and contain two active ingredients, namely amylmetacresol and 2,4-dichlorobenzyl alcohol. These ingredients are mild antiseptics, which can kill bacteria associated with mouth and throat infections.

The recommended dosage is one lozenge every 2–3 hours for adults.
