Chest Infection Antibiotics

Most respiratory infections, such as sore throats, coughs, and sinus congestion, are caused by viruses, which don’t respond to antibiotics.

You may need antibiotics only if your symptoms suggest a bacterial infection, including:

• Fever above 38°C lasting more than 3 days
• Symptoms worsening after initial improvement
• Cough with thick yellow or green mucus and chest pain
• Sinus pressure or ear pain that doesn’t settle after 10 days

Your smartscripts.ie doctor will review your symptoms and medical history to decide if antibiotics are appropriate.

All prescriptions follow HSE and Irish College of General Practitioners (ICGP) guidelines to ensure antibiotics are used safely and only when truly needed.

For mild or viral respiratory infections, most people feel better within 7-10 days with rest and supportive care.Helpful home measures include:Stay hydrated: warm fluids loosen mucus and ease throat pain.Steam inhalation or humidifiers: relieve nasal and chest congestion.Paracetamol or ibuprofen: reduce pain, fever, and body aches.Saltwater gargles: soothe sore throats.Rest and avoid smoking or alcohol, which can irritate your airways.If your symptoms worsen, last longer than 2 weeks, or include shortness of breath or chest pain, you should arrange an in-person medical review.
