Cough Relief: Home Remedies & When to See a Doctor

Most acute coughs are viral and self-limited. Symptomatic relief strategies:

1. Hydration: Water, broth, herbal tea thin mucus.
2. Humidifier: Cool-mist adds moisture; clean daily.
3. Saltwater gargle: ½ tsp salt in 8 oz warm water; soothes throat.
4. Honey: 1–2 tsp (age >1); antimicrobial, demulcent; as effective as some OTC cough meds.
5. OTC options: Dextromethorphan (suppressant), guaifenesin (expectorant), combination products. Follow labels.
6. Rest: Supports immune recovery.
7. Elevate head: Reduces postnasal drip cough at night.
8. Avoid irritants: Smoke, strong fumes, allergens.

See a Doctor If

• Cough >3 weeks (chronic)
• Fever >101°F, chest pain, dyspnea
• Hemoptysis (coughing blood)
• Unexplained weight loss, night sweats
• Underlying heart/lung disease

Antibiotics don't help viral coughs. Persistent cough warrants evaluation for asthma, GERD, postnasal drip, or other causes.
