Sore Throat

A sore throat is characterized by discomfort or pain in the throat, often making swallowing difficult. Patients may also experience dryness, redness, irritation, and burning sensations. Common causes include:

• Viral infections
• Bacterial infections
• Exposure to pollutants or irritants (e.g., cigarette smoke)
• Dry air
• Overuse of the voice
• Gastroesophageal reflux disease (GERD)
• Alcohol consumption
• Spicy foods

Infection with Group A beta-hemolytic Streptococcus, most commonly occurring in children aged 5 to 15 years, often results in tonsillitis, characterized by inflamed and swollen tonsils.
Other infections or irritations affecting the throat may present as pharyngitis, involving inflammation of the pharyngeal mucous membranes and a prominent sore throat, or as laryngitis, which is marked by inflammation of the larynx causing hoarseness and throat discomfort.

Prevention

• Regular hand washing with soap or alcohol-based sanitizers, especially after coughing, sneezing, or touching commonly used surfaces (e.g., doorknobs, elevator buttons).
• Avoid contact with people who have respiratory infections, such as colds or sore throats.
• For allergies:
  • Avoid exposure to triggers like dust, pet dander, and mold.

Self-Management

• Most sore throats resolve spontaneously within a week without medication.
• Get plenty of rest to aid the immune system.
• Stay hydrated: warm fluids can soothe the throat and thin mucus.
• Gargle with warm saltwater or mouthwash solutions.
• Use throat lozenges or cough drops to moisturize and soothe the throat.
• Wear a mask in polluted environments, especially a N95 mask during high PM2.5 exposure.
• Use a humidifier to reduce air dryness and relieve throat discomfort.

Treatment Options

1. Topical Products for Mouth and Throat Lesions

Topical medications that help relieve sore throat include lozenges, mouthwashes, gargles, and sprays containing:

• Anti-inflammatories: e.g., flurbiprofen, benzydamine.
• Local anesthetics: e.g., amylocaine, lidocaine, tetracaine.
• Antiseptics: e.g., amylmetacresol, benzalkonium chloride, benzoxonium, biclotymol, cetalkonium chloride, cetylpyridinium chloride, chlorhexidine, dequalinium chloride, dichlorobenzyl alcohol, hexetidine, povidone-iodine.

Some products may also contain antibiotics like bacitracin, fusafungine, miconazole, neomycin sulfate, or tyrothricin.

2. Analgesics and Antipyretics

Pain relievers and fever reducers like:

• Paracetamol
• Ibuprofen
• Aspirin

can relieve sore throat pain and associated fever.

Additional recommendations:

• For children under 6 months: use only paracetamol.
• Avoid using aspirin in children recovering from viral infections (e.g., measles, influenza, chickenpox) due to the risk of Reye’s syndrome.

3. Antibiotics

Antibiotics are indicated when a bacterial infection is suspected to:

• Reduce symptom severity
• Shorten disease duration
• Prevent complications
• Reduce transmission risk

Common antibiotics for bacterial sore throat include:

• Penicillins: amoxicillin, penicillin V, penicillin G benzathine.
• Cephalosporins: cephalexin, cefadroxil, cefuroxime, cefpodoxime, cefdinir, cefixime.
• Macrolides: azithromycin, clarithromycin.
• Others: clindamycin.
