Tyrozets Review Of Main Active Ingredients

Tyrozets contain two active ingredients:

  • Tyrothricin, an antibiotic and
  • Benzocaine, a local anesthetic

Tyrothricin is classified as an antibiotic, although not used in any other form in the treatment of bacterial infections in the U.K. Tyrothricin is a mixture of two different antibiotics gramicidin and tyrocidine.

Interestingly, tyrothricin is produced and extracted from the bacteria Bacillus brevis. Tyrothricin belongs to a group of antimicrobial peptides (AMPs). AMPs are produced by all organisms and play a role as the first-line defense against infections (Lang & Staiger, 2016).

Benzocaine is a local anesthetic that numbs the area to which it is applied and thus helps with managing pain.

Benzocaine can be found in other products used in conditions associated with pain, for example, oral gels (brand name: Orajel) to help with toothaches, or creams (brand name: Lanacane cream) for symptomatic relief of pain, irritation, and itching due to insect bites and other causes.

Anaesthetic throat sprays containing benzocaine can also be purchased, for example, Ultra Chloraseptic throat spray.

Tyrozets Review Of The Effectiveness

Tyrozets has been licensed since 2008. There is no information available publicly on the possible effectiveness of this product. Benzocaine produces numbness when Tyrozets are sucked.

Local anaesthetics are effective in reducing pain with a number of studies confirming their benefits (Quaba et al, 2005)., hence their wide application in dental procedures, cannulation, skin grafting, and other procedures.

Only properly set up clinical study could provide us with some useful information on Tyrozets effectiveness in terms of pain management and possible effect (if any) on the treatment of throat infections.

throat pain

The majority of sore throats are caused by viral infections, often associated with colds.

Most cases sore throats are self-limiting (no treatment is needed), lasting about 7 days.

Antibiotic treatment is generally not recommended for acute episodes of sore throats unless patients have other symptoms, are very unwell, or have other underlying illness or condition (NICE, 2017).

Patients should seek medical attention if (ibid):

  • symptoms get worse quickly or significantly
  • when symptoms last more than 7 days or
  • an individual becomes very unwell
  • a patient takes immunosuppressive medication

Limited information is available describing the effectiveness of tyrothricin in the management of sore throats. Nevertheless, some studies (in the lab) confirm its anti-bacterial as well as anti-viral and anti-fungal properties. As an antibiotic, tyrothricin has the best potential in treatments of skin infections (Lang & Staiger, 2016).

Lozenges increase saliva production by sucking action as fast as 1 minute after individuals start to use them. Saliva soothes the inflammation associated with sore throats and provides lubrication (Oxford & Leuwer, 2011).

Tyrozets Review Of Possible Side Effects

Patients are advised that soreness or blackness of a tongue may happen when Tyrozets are used. This goes away after the treatment is stopped.

Benzocaine can also cause skin rashes. Despite being safe and low-risk when used topically, benzocaine has the potential to cause methemoglobinemia, a life-threatening side effect. Methemoglobinemia rarely occurs in children or infants after benzocaine absorption.

Methemoglobinemia is characterised by:

  • decreased amounts of oxygen reaching tissues
  • skin discoloration (going blue) due to lack of oxygen
  • difficulty / heavy breathing

Acute Sore Throat: Self-Care Advice

Self-management of sore throats include:

  • Use of pain relief drugs such as paracetamol or ibuprofen (NSAIDs)
  • Use of sore throat lozenges with a local anesthetic, such as Tyrozets or other lozenges containing antiseptics or NSAIDs (Flurbiprofen, for example, Strefen honey & lemon lozenges)
  • Use of throat sprays containing a local anesthetic
  • Use of mouthwashes containing a local anesthetic
  • Gargle with warm, salty water
  • Adequate fluid intake


Note: there is little evidence confirming the effectiveness of any over the counter medication in the treatment of sore throats.


Despite the lack of evidence on effectiveness, Tyrozets lozenges can be used in the management of sore throat. As local anaesthetic benzocaine is effective in numbing the throat, possibly providing for the some pain relief. Patients should consider other self-care suggestions.

Paracetamol and ibuprofen are effective in reducing the pain associated with sore throats (Kenealy, 2011).
