Suppose your child is 4.5 years old and 15 kg, coughing can have many causes (viral infection, allergy, asthma, post-nasal drip, throat irritation, even pneumonia). Giving fexofenadine (an anti-allergic) can sometimes help if the cough is allergy-related, but if the cough is non-stop, disturbing sleep, or recurring after medicine, it’s important not to rely only on antihistamines.
You should see a pediatrician if:
Cough is severe, continuous, or worsening.
Associated with wheezing, fast breathing, chest indrawing, bluish lips, or difficulty speaking/feeding.
Associated with fever, vomiting, or poor oral intake.
Lasts more than 2–3 days without improvement.
While waiting to consult your doctor:
Keep child hydrated 🥤 – warm fluids (lukewarm water, light soups) help soothe throat irritation.
Steam inhalation / humidifier 🌫️ – moist air eases throat irritation and loosens mucus.
Honey (if above 1 year old) 🍯 – ½–1 teaspoon can reduce night cough (works better than cough syrups in some studies).
Head elevation during sleep 🛏️ – reduces post-nasal drip coughing at night.
Avoid cold air, strong perfumes, smoke, dust 🚭.
Fexofenadine only helps if the cough is allergy-related. Relief for 5 hours suggests irritation/allergy might be a trigger, but recurrence means the cause is still present.
Cough syrups (like Dextromethorphan, Codeine, etc.) are NOT recommended for toddlers (ineffective and risky).
Sometimes, doctors prescribe Montelukast, Levocetirizine, or inhalers (Asthalin, Budesonide) if asthma/allergy is suspected.
If there’s infection (bacterial/bronchitis/pneumonia), antibiotics or nebulizers may be needed – only a doctor can decide.
