Medical Therapy

Acute pharyngitis should be treated according to the etiologic agent. The most common causes of pharyngitis are

Viral infections

Most common cause of infection in children. The most common viral infection are Adenovirus, rhinovirus, influenza A and B, parainfluenza 1,2,3. Most of them a self limiting however a few may need antiviral in the immunocompromised.[1] [1]

Bacterial infections

They usually require antibiotics as group A beta-hemolytic streptococcus (GAS) is the most common . If bacteria are recovered from throat culture they do not need antibiotics are they dont cause pharyngitis .

Allergic infection

Treat allergic infection with systemic or topical anti-histaminics.

There are three types of treatment: symptomatic, remedial and preventive. Symptomatic treatments are aimed at reducing pain and symptoms. Remedial treatments attempt to cure pharyngitis by reducing its spread and speeding up the healing process. Preventive treatments attempt to block the start of an infection.

Remedial treatments are mostly effective for bacterial infections such as streptococcal infections. For viral infections, even with treatment, most cases of pharyngitis will still settle spontaneously within a few days. Hence the most popular method of treatment is symptomatic. Many preventive treatments are also remedial, thus those two treatments will be listed in the same section.

Twenty-two non-antibiotic managements for sore throat have been studied in controlled trials.[2]Analgesics are among the most effective, but there are many simple measures that can also be used.

Symptomatic treatments

  • Analgesics such as NSAIDs can help reduce the pain associated with a sore throat.[2]
  • Throat lozenges (cough medicine) are often used for short-term pain relief.
  • Avoid foods and liquids highly acidic in nature, as they will provoke temporary periods of intense pain.
  • Warm tea (true or Tisane) or soup can help temporarily alleviate the pain of a sore throat.
  • Cold beverages, popsicles and ice cubes numb the nerves of the throat somewhat, alleviating the pain for a brief time.
  • Mouthwash (when gargled) reduces the pain but only for a brief time.
  • Drinking heavy amounts of liquid reduces the pain for a short time.
  • Peppermint candy might help with some cases as well as other hard candies. It will reduce the pain for a short time.
  • Yogurt has been shown to help alleviate the pain temporarily by coating the affected area. Milk also has the same effect.
  • Gargling with warm saline solution may help reduce mucus. [3] While it is a popular household remedy, there is little evidence that it provides any long-term benefit.

Remedial and preventive treatments

Performing remedial treatments early when a patient's throat begins to feel scratchy may help the infection from spreading to the rest of the throat and back of the mouth, which can result in difficulty in swallowing. Treatment should begin the first or second day of the illness, however if the patient has a cold or the flu, the infection may still continue to spread to other areas such as the ears through the eustachian tube (causing an earache) and to the lungs through the trachea (causing a cough). Healthy people who will be in frequent contact with someone with pharyngitis may also try the measures below, of which some can be also be preventive, to help inhibit the start of an infection.

  • The use of antibiotics is a helpful remedial treatment when a bacterial infection is the cause of the sore throat. For viral sore throats, antibiotics have no effect.
  • Honey has long been used for treating sore throats due to its antiseptic properties.[4]
  • Swallowing a couple teaspoons of raw lemon or lime juice several times a day may help destroy microorganisms in bacteria-related throat infections.[5] Research also shows that lemon juice may destroy some viruses such as HIV.[6] This remedy should be started during the first or second day of sickness because citric acid can irritate a patient's throat tissues after pharyngitis becomes too widespread. If this is the case, the patient may try a diluted solution of lemon, honey and tea (or lemon with hot water).

Medical treatment for Acute Pharyngitis

Topical therapy

Oral rinses were more effective in treating conditions affecting oral cavity and base of the tongue whereas sprays were more effective in coating the posterior pharynx and hence they were used to treat posterior pharynx conditions.[7]

  1. Oral rinses
  • Salt water gargles which have been used since a long time have not shown any benefit in releiving throat pain . It is still used as it has minimal side effects.
  • Lidocaine, diphenhydramine and Maalox (Aluminium hydroxide, magnesium hydroxide and simethicone) have shown to be helpful. This combination can be used to treat Coxsackie A or B infection or herpes simplex. Avoid using the lidocaine over its recommended use.[8][9]
  • Benzydamine hydrochloride rinses have shown to be help reduce the pain in a few cases. However, they are used more frequently to treat radiation mucositis.[10][11][12][13][14]
  1. Sprays
  • Topical anesthetic sprays have been used in the past to treat pharyngitis , however their effect is not signigficant . They may also cause a few allergic reactions and side effects like methemoglobinemia and hence should not be used in children.
  • Chlorhexidine /benzydamine sprays are more effective in alleviating symptoms of acure viral pharyngitis and group A streptococcal pharyngitis.[15][16]
  1. Lozenges
  • Medical throat lozenges help reducing the duration of symptoms and also provide with some sympotomatic relief. They do come with a few side effects similiar to sprays like methemoglobinemia. They are not recommended for children as there is a risk of choking Lozenges containing antisepotics, menthol , anesthetics and antiflammatory agents have been used.[17][18][19]


Systemic Therapy

  1. Analgesics

Analgesics are prescribed for moderate to severe pain. Acetaminophen , Nonsteroidal antiinflammatory drugs (NSAID) have shown to decrease pain symptoms. They may also help in reducing fever and inflammation.[20][21][22][23][24][25]Aspirin should be avoided in children as it may cause Reye's syndrome .Only for severe pain codeine may be added to the NSAID.

  1. Glucocorticoids

They may alleviate pain , and may also be beneficial in patients of Group A streptococcal pharyngitis. No benefits were obtained by adding single dose glucocorticoid to antimicrobial therapy in children.[26][27][28][29][30][31][32][33]Since there are safer and more effective alternatives than glucocorticoids for pain relief and their long term use come with a few side effects they not recommended for symptomatic relief of throat pain.However in a few conditions like infectious mononucleosis a short term may be help in alleviating pain.
