Sore Throat and Cough: When Antibiotics Actually Help

The large majority of sore throats and acute coughs are viral: antibiotics change neither their duration nor their severity. They become useful when an examination points to a bacterial infection — streptococcal tonsillitis, acute middle ear infection in young children, prolonged sinusitis, pneumonia. The deciding factor is not the colour of your phlegm or the presence of a fever, but the clinical examination and how things evolve.

Why most sore throats do not need antibiotics

In adults, the vast majority of sore throats are viral. They tend to come with a runny nose, a cough and hoarseness — symptoms that actively argue against a bacterial cause. They resolve in three to seven days, treated or not.

Streptococcal tonsillitis presents differently: usually without cough or cold, with a clear fever, markedly inflamed tonsils and tender neck glands. It is more common between ages 3 and 15. That is the case where antibiotics genuinely come into the discussion, based on examination and, where available, a rapid test.

What about the cough?

Acute bronchitis in an adult without chronic lung disease is almost always viral. The cough can last two to three weeks, which is disconcerting but normal — duration alone does not indicate a secondary bacterial infection.

Two myths worth dropping:

• Yellow or green phlegm does not prove a bacterial infection. The colour reflects white blood cells, which are present in viral infections too.
• Having a fever is not enough either. Respiratory viruses cause fever routinely.

What points towards pneumonia is different: a high fever that persists, breathlessness, chest pain on breathing in, a raised respiratory rate, and above all abnormal findings when the chest is listened to.

When should you be seen?

• Difficulty swallowing your own saliva, a muffled voice, trouble opening the mouth, or one-sided neck swelling: prompt consultation, this can suggest a complication.
• Fever lasting beyond 3 days, or returning after improvement.
• Breathlessness at rest or on usually easy exertion, chest pain.
• Coughing up blood.
• Underlying risk: asthma, COPD, heart failure, immunosuppression, pregnancy, older age, infancy.

Call the emergency services (15)

For marked breathing difficulty, blue lips, swelling of the face or throat, drooling with an inability to swallow, or significant drowsiness.

What genuinely helps in the meantime

• Paracetamol for pain and fever, within the maximum dose.
• Drink regularly and humidify the air: this does more for an irritated throat than most syrups.
• Lozenges or anaesthetic sprays for temporary relief.
• Stop smoking during the episode — it is the most obvious aggravating factor.
• Be careful with cough suppressants. Suppressing a productive cough is not desirable, and they are not recommended in young children.

Why this matters beyond your own case

Antibiotic resistance is one of the leading health threats today, and it advances faster the more antibiotics are taken without indication. A course taken for a viral sore throat does not speed recovery, exposes you to diarrhoea, allergy and thrush, and makes future infections harder to treat. Reserving antibiotics for the situations where they work is not a restriction — it is what keeps them working.

What the examination adds

Looking at the throat and eardrums, feeling the glands, listening to the chest, counting the respiratory rate and measuring oxygen saturation: these take a few minutes and are usually enough to separate "this will pass" from "this needs an antibiotic" from "this needs a chest X-ray". That is precisely the decision a remote consultation cannot make.
