Medicine for sore throat and post-nasal drip

Post-nasal drip is mucus moving from the back of the nose into the throat. It can leave the throat dry, scratchy or sore and may trigger coughing or frequent throat-clearing. Allergic rhinitis can cause ongoing drainage, while a common cold, influenza or COVID-19 can cause short-term nasal and throat symptoms. Acid reflux can irritate the throat without much nasal congestion. A sore throat is a common presentation of strep throat, tonsillitis and glandular fever, but the symptom alone does not identify the cause.

Antibiotics do not treat viral illnesses or allergies. A clinician may consider them when an examination or test supports a bacterial throat infection. The right medicine also depends on pregnancy, age, allergies and other medicines you take.

Drink regularly and choose warm or cool fluids according to what feels soothing. Gargling with warm salty water may ease throat discomfort for adults who can gargle safely. Saline nasal spray or a gentle saline rinse can loosen mucus; use prepared sterile or appropriately treated water for a rinse. A pharmacist can advise on a suitable pain reliever and on an antihistamine or nasal spray when allergy symptoms are present. Follow the label, avoid doubling ingredients in combination cold remedies, and do not use a decongestant spray longer than directed.

Rest your voice, avoid cigarette smoke, and consider a humidified room. If reflux seems to trigger symptoms, smaller meals and avoiding lying down soon after eating may help while you arrange advice.

Seek urgent help for trouble breathing, inability to swallow liquids, drooling, rapidly increasing throat or neck swelling, severe dehydration, or a muffled voice with marked one-sided throat pain. Arrange a medical review if symptoms are severe, keep returning, follow a known exposure to COVID-19 or strep throat, or do not begin to improve. A clinician can examine your throat and nose and decide whether testing or prescription treatment is appropriate.

Ask which cause best fits your pattern, whether you need a throat test, and which products are safe with your current medicines. Mention fever, facial pain, reflux, allergies, pregnancy, immune problems, and how long the drainage has lasted.
