Triolif lozenges contain a combination of the antiseptic active substances, 2,4-dichlorobenzyl alcohol and amylmetacresol and the local anaesthetic lidocaine. Triolif is available over the counter (pharmacy-only) and is indicated for sore throat in adults and adolescents aged 12 or older.
There is no evidence that Triolif is better at relieving sore throat than alternatives such as Strepsils (2,4-dichlorobenzyl alcohol and amylmetacresol). The available studies describe a few cases of adverse reactions reported in combination treatment containing the three active substances in Triolif.
It is IRF's overall assessment that there is weak evidence of efficacy, and therefore none of the pain-relieving lozenges, e.g. Strepsils, Zyx or Hexokain, can be recommended to treat sore throat. However, it cannot be ruled out that the lozenges, including Triolif, may be perceived as offering pain relief, but the effect is presumably the same as that of ordinary throat pastilles.
