• No strong medicine is usually needed right now. • Try home remedies + safe over-the-counter options first for 5–7 more days. • See a doctor (general physician) if: • Cough lasts >3–4 weeks total • Starts producing colored phlegm • Gets worse at night or with wheezing • New fever, chest pain, breathing difficulty appears • Wife has asthma, smoking history, or other chronic illness

1. Best first steps (most effective for dry cough): • Drink plenty of warm fluids (water, herbal tea, warm lemon+honey water) — keeps throat moist • Take 1–2 teaspoons of pure honey (or honey + warm water/tea) 2–3 times a day — very good evidence for calming dry cough • Use a cool-mist humidifier in bedroom or steam inhalation (hot shower or bowl of hot water with towel over head) 2. Over-the-counter medicines (safe for most adults): • Dextromethorphan cough suppressant syrup (e.g., Benadryl Dry Cough, Corex-DX, Tusq-DX, Ascoril-D) — 10 ml every 6–8 hours if cough disturbs sleep • Levocetirizine or Cetirizine 5–10 mg at night (if mild allergy/runny nose is present) • Throat lozenges (e.g., Strepsils, Vicks, or plain menthol) to soothe throat 3. Avoid: • Antibiotic (not needed — no bacterial infection signs) • Strong codeine cough syrups (unnecessary and can cause side effects) • Cough mixtures with multiple ingredients unless advised Most dry post-viral coughs improve on their own in 3–4 weeks total. Honey + hydration + humid air usually help the fastest. If you want brand names available in India or if she has other medicines/allergies, let me know and I can guide more precisely. For complete peace of mind, a quick doctor visit is always safe. Take care
