Strepsils is a brand of throat lozenges manufactured by British–Dutch company Reckitt Benckiser.

[2][3] The primary active ingredients are dichlorobenzyl alcohol and amylmetacresol,[4] with some formulations containing ascorbic acid (vitamin C).

[5] Inactive ingredients include menthol, tartaric acid, and propylene glycol.

[7] These ingredients are mild antiseptics that can kill bacteria associated with mouth and throat infections.

However, as indicated in the package, research has not demonstrated the presence of an antibacterial agent to reduce the duration or severity of an infection.
