I now have solid textbook data. Here is a structured, evidence-based prescribing guide for cough in an 11-year-old girl.
Cough in an 11-Year-Old Girl - Prescribing Guide
Since no specific details were provided, this covers the most common clinical scenarios. Always examine the patient and determine the likely cause before prescribing.
Step 1: Determine the Cause First
The most common causes of acute cough at this age:
| Cause | Key Features |
|---|---|
| Viral URTI (most common) | Runny nose, low-grade fever, sore throat, no fast breathing |
| Community-acquired pneumonia (CAP) | Fever >38.5°C, fast breathing, chest signs, crepitations |
| Allergic / post-nasal drip | Seasonal, itchy eyes, sneezing, no fever |
| Asthma | Wheeze, nocturnal cough, atopy history, recurrent episodes |
| Pertussis | Paroxysmal "whooping" cough, prolonged >2 weeks |
| Mycoplasma pneumoniae | Dry hacking cough, headache, older child (>5 yr common) |
Scenario A: Viral URTI / Simple Cough-Cold (Most Likely)
No antibiotics are indicated for viral upper respiratory tract infection.
- Honey - 2.5 mL at bedtime (or diluted in warm water/tea). Shown to be effective and safe for cough in children with URTIs. - Tintinalli's Emergency Medicine, p. 857
- Saline nasal drops/spray - helps with congestion and post-nasal drip
- Adequate hydration - warm fluids, especially honey-lemon water
- Paracetamol (Acetaminophen) - 15 mg/kg/dose every 4-6 hours if fever is present (for an 11-yr-old ~500 mg per dose)
Do not give OTC cough suppressants (dextromethorphan, pholcodine). Evidence does not support their use in children, and they have been withdrawn from the market in several countries for children under 5. For older children the data on effectiveness and dosage is still lacking. Codeine is specifically contraindicated - risk of respiratory suppression. - Tintinalli's Emergency Medicine, p. 857
Review in 48-72 hours if not improving, or sooner if fast breathing, high fever, or chest signs develop.
Scenario B: Community-Acquired Pneumonia (if suspected)
Signs suggesting bacterial pneumonia: high fever, tachypnea, reduced breath sounds, crepitations, ill-appearing child.
First-line antibiotic (outpatient):
| Drug | Dose | Duration |
|---|---|---|
| Amoxicillin (first choice) | 40-90 mg/kg/day in 3 divided doses (max 3 g/day) | 7-10 days |
| Amoxicillin-clavulanate (if more severe or suspected resistant S. pneumoniae) | 45 mg/kg/day amoxicillin component, BD | 7-10 days |
Several major guidelines recommend amoxicillin with or without clavulanate as initial therapy for all children ≥3 months with simple CAP. - Tintinalli's Emergency Medicine, p. 857
If atypical pneumonia (Mycoplasma) is suspected (dry cough, headache, school-age child, bilateral patchy infiltrates, no response to amoxicillin after 48-72 h):
| Drug | Dose | Duration |
|---|---|---|
| Azithromycin | 10 mg/kg on Day 1, then 5 mg/kg/day on Days 2-5 (max 500 mg Day 1, 250 mg thereafter) | 5 days |
| Clarithromycin (alternative) | 15 mg/kg/day in 2 divided doses (max 500 mg BD) | 7-10 days |
Scenario C: Cough-Variant Asthma / Wheeze
- Salbutamol (Albuterol) MDI - 2-4 puffs (100 mcg/puff) via spacer every 4-6 hours as needed
- Montelukast - 5 mg once daily at bedtime (for ages 6-14 yr) if allergic component
- Refer for formal asthma assessment if recurrent
Scenario D: Allergic/Post-Nasal Drip Cough
- Cetirizine - 10 mg once daily OR
- Loratadine - 10 mg once daily (non-sedating, preferred for daytime)
- Fluticasone nasal spray - 50 mcg/nostril once daily if significant allergic rhinitis
Red Flags - Refer / Investigate Urgently
- SpO2 < 94%, respiratory distress, or cyanosis
- Fast breathing (>30/min at this age)
- Cannot drink or eat
- Cough for >3 weeks without improvement (think TB, foreign body, bronchiectasis)
- Blood in sputum (hemoptysis)
- Weight loss or night sweats
Important disclaimer: This is a general clinical guide. The specific prescription must be based on clinical examination, local antibiogram patterns, drug availability, and the individual patient's history (allergies, comorbidities). Please assess the child in person before prescribing.
