What is Strepsils® used for?

Strepsils® are lozenges that have antiseptic properties. Antiseptics are chemicals or drugs used to kill microorganisms such as bacteria and viruses on living tissues. Antiseptics are different from antimicrobials because they are not ingested or administered through the blood nor do they have specific action against certain species of bacteria, fungi, or viruses.

Strepsils® lozenges are available in a variety of flavors and formulations that aim to treat different illnesses. Unlike antibiotics, the lozenges can be bought over the counter without a prescription. They work best at the first sign of illness, before bacteria or other microorganisms have time to replicate and travel further down the throat.

Strepsils® is mainly indicated for:

  • Itchy, sore throat
  • Painful, irritated throat
  • Throat inflammation
  • Sore throat with cough
