For a generally healthy adult with 4 days of cough with mucus and body aches, and no breathlessness or high fever, initial symptomatic medicines can be:
- Paracetamol (acetaminophen) 500 mg every 6-8 hours as needed for fever/body ache. Maximum 3,000 mg/day without clinician advice. Avoid or seek advice first with liver disease, heavy alcohol use, or if already taking a cold/flu combination product containing paracetamol.
- Guaifenesin 200-400 mg every 4 hours as needed, with plenty of warm fluids, to loosen thick sputum. Follow the specific product label.
- Dextromethorphan can be used only if cough is dry/irritating or prevents sleep, but avoid it if mucus is substantial, or if taking antidepressants such as SSRIs/MAOIs, tramadol, or certain other medicines without pharmacist/clinician advice.
- Honey 1-2 teaspoons at bedtime can reduce cough. Do not give honey to children under 1 year.
Do not start antibiotics such as azithromycin, amoxicillin, or cefixime without medical examination. Viral illness/acute bronchitis is common, and antibiotics are usually not useful.
Get examined before taking medicines if this is for a child, pregnancy/breastfeeding, age over 65, or if there is asthma/COPD, heart/kidney/liver disease, diabetes, ulcers, or regular medication use.
Seek urgent assessment for shortness of breath, chest pain, confusion, blood in sputum, oxygen saturation below 94%, fever above 38 C persisting or worsening, or marked weakness.
