I now have all the information needed for a thorough answer. Here is the complete IMNCI pneumonia classification with treatment:
IMNCI Pneumonia Classification and Treatment
IMNCI (Integrated Management of Neonatal and Childhood Illness) uses a color-coded, signs-based classification system to manage respiratory illness in children. There are two separate frameworks - one for children aged 2 months to 5 years, and one for young infants (under 2 months).
A. Children Aged 2 Months to 5 Years
Classification and Signs
| Classification | Signs |
|---|---|
| I. Very Severe Disease | Not able to drink; convulsions; abnormally sleepy or difficult to wake; stridor in calm child; severe malnutrition |
| II. Severe Pneumonia | Chest indrawing (lower chest wall draws in when child breathes IN) |
| III. Pneumonia (not severe) | No chest indrawing BUT fast breathing: ≥50/min (age 2–12 months); ≥40/min (age 12 months–5 years) |
| IV. No Pneumonia: Cough or Cold | No chest indrawing AND no fast breathing |
Fast breathing cut-offs to memorize:
- 2–12 months: ≥ 50 breaths/min
- 12 months–5 years: ≥ 40 breaths/min
Treatment by Classification
I. Very Severe Disease
- Refer URGENTLY to hospital
- Give first dose of an antibiotic
- Treat fever, if present
- Treat wheezing, if present
- If cerebral malaria is possible, give an antimalarial
II. Severe Pneumonia (Chest Indrawing)
- Refer URGENTLY to hospital
- Give first dose of an antibiotic
- Treat fever and wheezing if present
- If referral is not feasible: treat with antibiotic and follow closely
Inpatient antibiotic regimen for severe pneumonia (2 months - 5 years):
| Phase | Drug | Dose | Interval | Route |
|---|---|---|---|---|
| First 48 hours | Benzyl penicillin | 50,000 IU/kg/dose | 6-hourly | IM |
| OR Ampicillin | 50 mg/kg/dose | 6-hourly | IM | |
| OR Chloramphenicol | 25 mg/kg/dose | 6-hourly | IM | |
| If IMPROVES (next 3 days) | Procaine penicillin | 50,000 IU/kg (max 4 lac IU) | Once daily | IM |
| OR Ampicillin | 50 mg/kg/dose | 6-hourly | Oral | |
| OR Chloramphenicol | 25 mg/kg/dose | 6-hourly | Oral | |
| If NO IMPROVEMENT (next 48 hr) | Change antibiotic: if ampicillin used → switch to chloramphenicol |
Minimum antibiotic duration: 5 days, and at least 3 days after the child improves.
III. Pneumonia (Not Severe)
- Advise mother on home care
- Give an antibiotic (cotrimoxazole - see dosing table below)
- Treat fever, if present; treat wheezing, if present
- Return in 2 days for reassessment, or earlier if worsening
Cotrimoxazole dosing for pneumonia (outpatient):
| Age/Weight | Paediatric tablet (SMX 100 mg + TMP 20 mg) | Syrup (5 ml = SMX 200 mg + TMP 40 mg) |
|---|---|---|
| < 2 months (3–5 kg) | 1 tablet twice daily | 2.5 ml twice daily |
| 2–12 months (6–9 kg) | 2 tablets twice daily | 5 ml twice daily |
| 1–5 years (10–19 kg) | 3 tablets twice daily | 7.5 ml twice daily |
- Reassess at 48 hours; if improved, continue for 3 more days (total 5 days)
- If no change at 48 hours: continue another 48 hours and reassess
- If worsens at any point: hospitalize immediately
IV. No Pneumonia: Cough or Cold
- No antibiotic needed (usually viral)
- If cough > 30 days: refer for further assessment (TB, asthma, whooping cough)
- Treat fever and wheezing if present
- Advise home care; child usually recovers in 1–2 weeks
Reassessment at 2 Days (for child on antibiotic for pneumonia)
| Status | Action |
|---|---|
| Worse (can't drink, chest indrawing, other danger signs) | Refer URGENTLY to hospital |
| Same (no improvement) | Change antibiotic OR refer |
| Improving (breathing slower, less fever, eating better) | Finish 5 days of antibiotic |
B. Young Infants (Under 2 Months)
Young infants differ critically - they can deteriorate rapidly, often lack a cough, and show non-specific signs. Even mild-looking pneumonia in this age group is treated as severe.
Fast breathing cut-off for young infants: ≥ 60 breaths/min
Classification and Signs
| Classification | Signs |
|---|---|
| Very Severe Disease | Stopped feeding well; convulsions; abnormally sleepy or difficult to wake; stridor in calm child; wheezing; fever (≥38°C) or low body temperature |
| Severe Pneumonia | Severe chest indrawing; OR fast breathing ≥ 60/min |
| No Pneumonia: Cough or Cold | No severe chest indrawing AND no fast breathing (< 60/min) |
Note: In young infants, any pneumonia is classified as severe. Mild chest indrawing alone is NOT used to classify pneumonia (unlike older children) because the chest wall is soft and some indrawing is normal.
Treatment
Very Severe Disease
- Refer URGENTLY to hospital
- Keep young infant warm
- Give first dose of antibiotic
Severe Pneumonia
- Refer URGENTLY to hospital; keep warm; give first dose of antibiotic
- If referral not feasible: treat with antibiotic and follow closely
Home care advice for No Pneumonia cases:
- Keep infant warm
- Breastfeed frequently
- Clear nose if it interferes with feeding
- Return quickly if: breathing becomes difficult or fast, feeding worsens, or infant becomes sicker
Key Points to Remember
- Cotrimoxazole is the drug of choice for outpatient (non-severe) pneumonia in India - efficacy equivalent to ampicillin/procaine penicillin, with cure rates up to 95%.
- Cotrimoxazole is not routinely recommended under 2 months - these infants should be referred; only use if referral is delayed.
- Do NOT give cotrimoxazole to premature babies or neonatal jaundice cases.
- Chest indrawing = severe pneumonia; fast breathing alone = pneumonia (not severe) - this distinction drives the referral vs. home treatment decision.

Isnt amoxicillin prescribed?

WHO IMNCI revised 2014 amoxicillin first line pneumonia cotrimoxazole replaced
Yes, you are absolutely correct. Here is the full picture:
Amoxicillin vs. Cotrimoxazole in IMNCI - What Changed and Why
The Short Answer
Amoxicillin is now the WHO-recommended first-line antibiotic for non-severe pneumonia in children. This replaced cotrimoxazole following a major WHO guideline revision in 2014.
What the 2014 WHO IMCI Revision Changed
The WHO 2014 revised guidelines introduced two key changes:
Change 1 - Simplified classification (3 categories → 2):
| Old (3 categories) | New (2 categories) |
|---|---|
| Very severe disease | Severe pneumonia (injectable antibiotics, refer) |
| Severe pneumonia (chest indrawing) | Pneumonia (oral amoxicillin, home care) |
| Pneumonia (fast breathing) | (merged into "Pneumonia" above) |
Both "fast breathing" and "chest indrawing" pneumonia in children 2–59 months are now treated outpatient with oral amoxicillin.
Change 2 - Amoxicillin replaces cotrimoxazole:
- Oral amoxicillin is the new first-line treatment for outpatient pneumonia
- Dose: 40 mg/kg/day in 2 divided doses (twice daily), for 5 days (can be 3 days in low-HIV settings)
- Preferred formulation: 250 mg dispersible tablet
Why Was Cotrimoxazole Replaced?
Evidence showed cotrimoxazole was inferior to amoxicillin:
- Clinical failure rate with cotrimoxazole was significantly higher than amoxicillin (OR 1.33; 95% CI 1.05–1.67)
- In chest indrawing pneumonia specifically, treatment failure: amoxicillin 18% vs. cotrimoxazole 33% (p=0.009)
- Oral amoxicillin was also found equivalent to injectable penicillin/ampicillin for chest indrawing pneumonia - meaning outpatient treatment became feasible even for this group
Why the Textbook Said Cotrimoxazole
The Park's Textbook edition in the library reflects older Indian national ARI guidelines that pre-date the 2014 WHO revision. At that time, cotrimoxazole was favored in India due to cost, availability, and demonstrated efficacy in local studies (cure rates up to 95%). Those guidelines have since been superseded.
Current Standard (Post-2014 WHO / Updated IMNCI)
| Category | Signs | Treatment |
|---|---|---|
| Pneumonia | Fast breathing ± chest indrawing (2–59 months) | Oral amoxicillin 40 mg/kg/day BD x 5 days; home care |
| Severe Pneumonia | Danger signs (can't drink, convulsions, stridor, very severe malnutrition) | Refer urgently; injectable ampicillin + gentamicin |
For severe pneumonia requiring hospitalization, the current WHO recommendation is ampicillin + gentamicin (replacing the older benzyl penicillin/chloramphenicol regimen).
Bottom line: You are correct - amoxicillin is what is currently prescribed per updated IMNCI/WHO guidelines. Cotrimoxazole appears in older textbooks and may still be used in some settings as an alternative, but it is no longer the first-line recommendation.
