So a cough at day 10 or day 14 does not automatically mean you have developed a bacterial chest infection.
Why does the cough remain when I otherwise feel better?
A respiratory infection irritates the airways. Even after the virus itself is settling, the airways may remain inflamed and sensitive. Mucus and post-nasal drip can also continue triggering the cough reflex.
That is why you may feel almost completely recovered while the cough stubbornly continues.
How long does a cold last?
Cold symptoms generally improve gradually. A cough can outlast a blocked or runny nose, sore throat, headache, fever and general aches. If symptoms suddenly deteriorate rather than steadily improve, the picture changes and medical review may be appropriate.
How long does flu last?
Flu itself often improves within several days, but recovery can take longer. HSE information notes that fatigue can persist for around two weeks and cough can continue for three weeks or longer in some people. Flu tends to start more suddenly than a cold and usually causes more marked exhaustion and body aches.
Does green or yellow phlegm mean I need antibiotics?
Not necessarily. HSE antimicrobial guidance specifically notes that yellow or green sputum does not, by itself, prove that an infection is bacterial or that antibiotics are needed.
Viruses cause most cases of acute bronchitis in otherwise healthy adults, and antibiotics do not make viral infections resolve faster.
What can I do for the cough?
- Rest and keep well hydrated.
- Warm drinks may soothe the throat.
- Honey may help in adults and children over one year old.
- Paracetamol or ibuprofen may help associated pain or fever where suitable.
- Ask your pharmacist about symptom-relief products if needed.
Cough medicines may reduce symptoms for some people but do not remove the underlying cause.
| PrivateGP.ieIf a cough is lingering and you are not sure whether you need antibiotics, an examination or simply more time, you can speak privately with an Irish GP online through PrivateGP.ie. Many coughs can be triaged remotely, but symptoms suggesting pneumonia or another chest problem may require an in-person chest examination or observations. |
