Antibiotics for a throat infection

Starting an antibiotic without assessment can expose you to diarrhoea, nausea, rash, allergic reactions, and interactions without improving a viral illness. The chosen medicine also depends on allergy history, pregnancy, other medicines, and local prescribing guidance.

A sore throat may come from a respiratory virus, a bacterial infection, irritation, or inflammation elsewhere in the upper airway. Cough, runny nose, hoarseness, swollen neck glands, fever, or tonsil changes can inform the assessment, but no single symptom reliably identifies the cause.

When bacterial infection is considered likely or confirmed, the prescription is selected for the suspected organism and the patient's circumstances. Antibiotics should not be shared or saved for a later illness, because a different infection may require a different approach.

Drink regularly and choose cool or warm fluids according to comfort. Soft foods, rest, and avoiding smoke may ease irritation. A pharmacist can advise whether paracetamol, ibuprofen, or a throat preparation suits your age, medical history, pregnancy status, and current medicines.

If antibiotics are prescribed, take each dose as directed and complete the instructed course unless the prescriber tells you to stop. Contact a clinician if doses are vomited, the medicine cannot be swallowed, troublesome side effects occur, or symptoms worsen despite treatment.

Seek urgent medical care for difficulty breathing, inability to swallow saliva, drooling, a muffled voice, severe neck swelling, rapidly worsening one-sided throat pain, difficulty opening the mouth, confusion, or unusual drowsiness. These features can signal airway narrowing, dehydration, or infection around the tonsil or deeper neck tissues.

Request assessment if fever persists, a rash appears, fluid intake falls, urine becomes scant or dark, symptoms return after improving, or the sore throat is prolonged. People with reduced immunity or serious long-term illness should seek advice earlier.

Tell the clinician about previous antibiotic reactions, recent antibiotic use, pregnancy or breastfeeding, kidney or liver problems, and all medicines or supplements. Ask what diagnosis is suspected, whether testing would change treatment, what side effects require action, and when you should be reassessed.
