Over-the-Counter Sore Throat Treatments: Key Options and Efficacy
Common OTC Sore Throat Remedies: Lozenges, Sprays, and Gargles
Over-the-counter (OTC) treatments for sore throat are widely used for quick symptom relief, especially since most sore throats are caused by viral infections and do not require antibiotics 14710. The most common OTC options include medicated lozenges, throat sprays, and gargles, which are designed to provide local pain relief and target inflammation directly at the site of discomfort 12410.
Medicated Lozenges: Amylmetacresol, 2,4-Dichlorobenzyl Alcohol, and Hexylresorcinol
Lozenges containing amylmetacresol and 2,4-dichlorobenzyl alcohol (AMC/DCBA) have been shown to provide rapid and effective relief from sore throat pain. Clinical studies demonstrate that these lozenges can reduce throat soreness, improve swallowing, and offer both warming and cooling sensations within minutes, with effects lasting up to two hours 123. Additionally, hexylresorcinol lozenges have demonstrated rapid bactericidal activity against common throat pathogens, achieving over 99.9% reduction in bacteria within five minutes, which matches the typical time a lozenge dissolves in the mouth .
Throat Sprays and Immune Complexes
Throat sprays are another popular OTC option. Some sprays contain mucosal immune complexes (such as lysozyme, lactoferrin, and aloe) that support the throat’s natural defenses and reduce inflammation. Clinical trials show that these sprays can significantly decrease sore throat pain and other cold symptoms within 36 hours, especially when combined with anti-inflammatory agents like aspirin .
Local Anesthetics: Benzocaine and Lidocaine
OTC products with local anesthetics such as benzocaine and lidocaine are also commonly used to numb throat pain. These agents provide quick, temporary relief by blocking nerve signals in the throat. They are available in various forms, including lozenges, sprays, and gels, and are generally considered safe when used as directed .
Non-Antibiotic Anti-Inflammatory Options
Given the high rate of viral sore throats and concerns about antibiotic resistance, guidelines recommend non-antibiotic OTC treatments. Flurbiprofen, a non-steroidal anti-inflammatory drug (NSAID), is available in lozenges and sprays and can help reduce inflammation and pain locally in the throat . These options are preferred over antibiotics for most uncomplicated sore throats 4710.
Caution with Topical Antibiotics
Some OTC sore throat products contain topical antibiotics, but their use is discouraged due to the risk of promoting bacterial resistance. Studies highlight that up to 80% of sore throats are viral, and even bacterial cases often resolve without antibiotics. Overuse of topical antibiotics can contribute to the development of resistant bacteria, so their use should be limited and reserved for specific cases as advised by healthcare professionals 479.
Practical Guidance for Self-Treatment
Pharmacists play a key role in guiding patients to appropriate OTC sore throat treatments and in helping to distinguish between uncomplicated cases suitable for self-care and those needing medical attention. Using a systematic approach or algorithm in pharmacies can improve care and reduce the risk of missing serious conditions .
Conclusion
OTC treatments for sore throat, including medicated lozenges (AMC/DCBA, hexylresorcinol), throat sprays with immune complexes, and local anesthetics (benzocaine, lidocaine), are effective for rapid symptom relief. Non-antibiotic anti-inflammatory options like flurbiprofen are recommended to avoid unnecessary antibiotic use and reduce the risk of resistance. Pharmacist guidance and careful product selection are important for safe and effective self-management of sore throat symptoms 12345678+2 MORE.
