The common cold is caused by viruses, so no antibiotic or miracle cure exists — it must run its course in 7-10 days. Medicines can manage symptoms, but many products in the aisle have surprisingly little evidence behind them.
What works: paracetamol for fever and aches; plenty of fluids and rest; honey for cough (genuinely effective, including for children over one); saline drops for a blocked nose in children. Steam inhalation can ease congestion.
What to be cautious about: decongestant syrups for young children (many are not recommended under six), codeine-based cough syrups (addictive, strictly regulated, not for children), and mixing multiple cold products — many combine paracetamol, and doubling it can harm the liver.
A cough lasting more than three weeks, high fever, breathing difficulty or coughing blood are not colds — see a doctor. Otherwise, treat the symptoms, hydrate and wait it out. Your pharmacist can steer you to the product with the least fluff and the most evidence.
What actually works for cough and cold?
What works is managing symptoms: paracetamol for fever and aches, fluids and rest, honey for cough, saline drops for children’s blocked noses and steam for congestion.
Which cold medicines should you avoid?
Avoid codeine-based cough syrups, decongestant syrups for young children, and mixing multiple cold products — many combine paracetamol and doubling it can harm the liver.
What should you actually buy from the pharmacy for a cold?
Go in with a short list so you leave with what works. For fever and aches: paracetamol — plain, in the right dose, without added ingredients you don’t need. For a cough: honey-based relief for adults and children over one year (honey genuinely calms coughs), and for a dry, irritating cough a simple suppressant under guidance. For a blocked nose: saline drops for children — safe and effective — and steam inhalation for adults; decongestant sprays are short-term tools at best. For a sore throat: warm saline gargles, plenty of fluids and lozenges if they help. Skip the multi-symptom cold syrups that combine paracetamol with decongestants — they increase the risk of accidental paracetamol overdose and have thin evidence. Never buy codeine-based cough syrup, which is addictive, strictly regulated and unsuitable for children. If symptoms last beyond three weeks, fever stays high, or breathing becomes difficult, see a doctor. For a normal cold, the best prescription is hydration, rest and the shortest medicine list possible.
