Diagnosis

Treatments to relieve symptoms include:

Over-the-Counter Pain Medication

Sore throat pain can be treated with nonsteroidal anti-inflammatory medications (NSAIDs), such as acetaminophen or ibuprofen.
  • Note: Aspirin is not recommended for children with a current or recent viral infection. Check with your doctor before giving your child aspirin.

  • Gargling with warm salt water can help relieve a sore throat.
  • Using throat lozenges.
  • Drinking plenty of fluids. Hot drinks and soups can be very soothing for a sore throat.
  • Using running a cool-mist humidifier. It can help keep your nasal passages moist and reduce congestion.

  • Practice good hygiene, including careful hand washing.
