Strepsils lozenges contain 2,4-dichlorobenzyl alcohol and amylmetacresol, both antibacterial ingredients that soothe sore throats and kill the bacteria responsible for them. Additionally, these lozenges have a menthol vapour to help alleviate nasal congestion.

To take the lozenges, follow these steps:

• Remove the blister pack from the cardboard carton.
• Pop one lozenge from the blister pack.
• Place it in your mouth and allow it to dissolve slowly.

You should avoid taking Strepsils Sore Throat lozenges if you're allergic to 2,4-dichlorobenzene alcohol, amylmetacresol or levomenthol. Individuals with intolerances to some sugar types, including sucrose-isomaltose, fructose and glucose-galactose, should also avoid lozenges.

If you've been taking Strepsils for a couple of days and your symptoms aren't improving, it's best to speak to a GP or pharmacist. While each lozenge eases sore throats and helps unblock the nose, they can't treat bacterial infections.
