- Red flag symptoms to watch for (return immediately if...)
15. PROGNOSIS
- Good / Guarded / Poor - with brief reasoning
16. CASE SUMMARY (Optional but recommended)
A 2-4 line summary of the case:
"Mr. XYZ, 45M, presented with fever and cough for 5 days. On examination, he had tachycardia, tachypnea, and crepitations in the right lower zone. CXR showed right lower lobe consolidation. He was diagnosed with Community Acquired Pneumonia and started on amoxicillin-clavulanate and supportive care."
Tips for OP Case Writing:
- Keep it concise compared to an IP (inpatient) case - focus on the presenting complaint
- Negative findings are as important as positive ones
- Always justify your provisional diagnosis with clinical findings
- OP management leans toward oral medications and outpatient monitoring (no IV lines, no nursing charts needed unlike IP)

- Dysmenorrhea (Ibuprofen, Mefenamic acid) is very common if female students are attending
- Always keep Adrenaline accessible for anaphylaxis - never go to a camp without it
- Keep a stock of ORS sachets and Albendazole (deworming is often done en masse at camps)
- Carry a prescription pad and document every patient seen
What is the difference between between chloramphinamine and cetrizine

Here is a clear, side-by-side comparison sourced from pharmacology textbooks:
Chlorpheniramine vs Cetirizine
The Core Difference in One Line
Chlorpheniramine = 1st generation antihistamine (sedating) Cetirizine = 2nd generation antihistamine (non-sedating)
Both block H1 histamine receptors but differ in how selectively they do so.
Detailed Comparison Table
| Feature | Chlorpheniramine (CPM) | Cetirizine |
|---|---|---|
| Generation | 1st generation | 2nd generation |
| Other names | Chlor-Trimeton, Piriton | Zyrtec, CTZ, Alerid |
| Mechanism | H1 receptor blocker + anticholinergic + crosses BBB | Selective H1 receptor blocker, minimal anticholinergic |
| CNS penetration | HIGH - crosses Blood Brain Barrier easily | LOW - minimal BBB penetration |
| Sedation | YES - significant sedation (drowsiness) | Minimal to none (slight sedation possible at higher doses) |
| Anticholinergic effects | YES - dry mouth, urinary retention, blurred vision, constipation | Minimal to none |
| Onset of action | 30-60 minutes | 1 hour |
| Duration of action | 4-6 hours (short) | 24 hours (long - once daily dosing) |
| Dose | 4 mg TDS/QID | 10 mg OD (at night) |
| Dosing frequency | 3-4 times a day | Once a day |
Side Effects Comparison
| Side Effect | Chlorpheniramine | Cetirizine |
|---|---|---|
| Drowsiness / Sedation | +++ (major problem) | + / - (mild, rarely) |
| Dry mouth | ++ | - |
| Urinary retention | ++ (caution in BPH) | - |
| Blurred vision | ++ | - |
| Constipation | + | - |
| Headache | - | + (occasionally) |
| Impairs driving/work | YES - avoid driving | Generally safe |
| Cognitive impairment | YES | No |
When to Use Which?
| Clinical Situation | Preferred Drug |
|---|---|
| Allergic rhinitis (day time) | Cetirizine (non-sedating, OD dosing) |
| Urticaria / Hives | Cetirizine (better for chronic use) |
| Cold + needs to sleep at night | Chlorpheniramine (sedation is useful here) |
| Motion sickness | Chlorpheniramine (CNS action useful) |
| Patient who drives / operates machinery | Cetirizine (safe) |
| Elderly patients | Cetirizine (avoid CPM - risk of urinary retention, confusion) |
| Child with allergic cold at bedtime | Chlorpheniramine (helps them sleep too) |
| Chronic allergic conditions (long-term) | Cetirizine (better tolerated long term) |
| Acute allergic reaction (injection form) | Chlorpheniramine (Avil injection available) |
| Anaphylaxis adjunct | Chlorpheniramine injection (Avil) |
| Pregnancy | Both relatively safe; Cetirizine preferred (Category B) |
Key Pharmacology Points
Chlorpheniramine:
- Blocks H1 + muscarinic (M1) + alpha receptors
- Sedation = CNS H1 blockade
- Anticholinergic = muscarinic blockade
- Short half-life → needs multiple doses/day
Cetirizine:
- Selective H1 blocker (peripheral > central)
- Active metabolite of Hydroxyzine
- Long half-life (~10 hours) → once daily dosing
- Also has some anti-inflammatory effect (inhibits eosinophil migration)
Simple Memory Trick
"Chlorpheniramine = Causes CNS sedation" "Cetirizine = Clean (no sedation), Convenient (once daily)"
Bottom line for your OP camp: Use cetirizine for daytime allergies (rhinitis, urticaria, itching) since patients need to stay alert. Use chlorpheniramine when a mild sedative effect is acceptable (nighttime cold, acute allergic reactions) or when you need the injectable form (Avil/Pheniramine) for acute reactions.

Here is a complete guide on Montec - when and to whom it is given:
MONTEC - Complete Guide
What is Montec?
Montec = Montelukast 10 mg + Levocetirizine 5 mg (combination tablet)
It works on two separate pathways that cause allergic symptoms:
Allergen exposure
↓
Mast cell / Eosinophil activation
↓ ↓
Histamine release Leukotriene release
↓ ↓
Levocetirizine Montelukast
(H1 blocker) (CysLT1 blocker)
↓ ↓
Blocks sneezing, Blocks congestion,
itching, runny nose bronchoconstriction,
mucosal inflammation
The Two Drugs Explained
| Component | Montelukast | Levocetirizine |
|---|---|---|
| Class | Leukotriene Receptor Antagonist (LTRA) | 2nd generation antihistamine |
| Receptor blocked | CysLT1 (leukotriene receptor) | H1 histamine receptor |
| Main action | Reduces bronchoconstriction + inflammation + nasal congestion | Reduces itching, sneezing, runny nose, hives |
| Active metabolite of | - | Cetirizine |
| Sedation | None | Minimal |
INDICATIONS - When to Give Montec?
1. Allergic Rhinitis (Most common use)
- Sneezing, runny nose, nasal congestion, itchy/watery eyes
- Especially when nasal blockage is a prominent feature (leukotrienes cause congestion - antihistamines alone don't fix this well)
- Both seasonal and perennial allergic rhinitis
2. Asthma + Allergic Rhinitis together
- A patient with wheeze/cough AND nasal allergy - Montec covers both
- Montelukast alone is approved for mild-moderate asthma maintenance
- Particularly useful in children with asthma + rhinitis (per Katzung)
3. Urticaria (Hives)
- Chronic spontaneous urticaria not controlled by antihistamine alone
- The leukotriene blocker adds extra anti-inflammatory cover
4. Exercise-Induced Bronchoconstriction (EIB)
- Montelukast reduces post-exercise wheeze
- Ideal for athletes/students with exercise-triggered symptoms
5. Aspirin-Sensitive Asthma (Samter's Triad)
- These patients overproduce leukotrienes - montelukast is specifically indicated
- (Aspirin + nasal polyps + asthma)
6. Cold-Induced / Post-viral Cough with allergy
- Persistent cough after cold with allergic component responds well
TO WHICH PATIENTS IS MONTEC GIVEN?
| Patient Type | Give Montec? | Reason |
|---|---|---|
| Allergic rhinitis with nasal blocking | ✅ YES | Addresses both histamine + leukotriene pathways |
| Asthma + rhinitis (dual diagnosis) | ✅ YES | Single tablet manages both |
| Antihistamine-alone failed allergic rhinitis | ✅ YES | Adding leukotriene blocker helps |
| Child with wheeze + running nose | ✅ YES | Standard combination in pediatrics |
| Chronic urticaria | ✅ YES | Better control than antihistamine alone |
| Exercise-triggered wheeze | ✅ YES | Take 2 hours before exercise |
| Pure bronchial asthma (no rhinitis) | ⚠️ Consider | Montelukast alone may suffice |
| Simple common cold (no allergy) | ❌ NO | Overkill, not needed |
| Bacterial infection | ❌ NO | Not an antibiotic, won't help |
Dosing
| Age | Dose | Timing |
|---|---|---|
| Adults & children >15 yrs | Montec tablet (Montelukast 10 mg + Levocetirizine 5 mg) | Once daily at night |
| Children 6-14 yrs | Paediatric formulation (Montelukast 5 mg + Levocetirizine 2.5 mg) | Once daily at night |
| Children 2-5 yrs | Syrup/granules available | Once daily at night |
Always give at night - leukotrienes peak at night (explains 3-4 AM asthma attacks), and the mild sedation of levocetirizine is an added benefit at bedtime.
Side Effects to Watch For
| Side Effect | Which Component |
|---|---|
| Mild drowsiness | Levocetirizine |
| Headache | Either |
| Nausea / abdominal pain | Montelukast |
| Neuropsychiatric effects (rare but important!) | Montelukast - anxiety, depression, suicidal thoughts (FDA black box warning 2020) |
| Dry mouth (rare) | Levocetirizine |
⚠️ Important: FDA (2020) issued a black box warning for Montelukast for neuropsychiatric events (mood changes, sleep disturbances, depression, suicidal ideation). Inform patients/parents to report behavioral changes immediately.
Contraindications
- Known hypersensitivity to either component
- Severe hepatic impairment (montelukast is hepatically metabolized)
- Use cautiously in patients with psychiatric history (due to neuropsychiatric warning)
Simple Way to Remember When to Give Montec at OP Camp
"Allergy with NOSE BLOCK + WHEEZE = Give Montec"
- Runny nose ✅ + Blocked nose ✅ + Sneezing ✅ + Itchy eyes ✅ + Cough/wheeze ✅ = Montec
- Pure runny nose, no block = Cetirizine alone may be enough
- If antihistamine failed = add Montelukast (Montec)

Cold & Sore Throat - When to Give / NOT Give Antibiotics
GOLDEN RULE FIRST
90% of sore throats and colds are VIRAL. Antibiotics kill bacteria - they do NOTHING for viruses. Giving antibiotics unnecessarily = antibiotic resistance + side effects + waste of money.
STEP 1 - Use the CENTOR SCORE to Decide
This is the standard clinical tool to decide if a sore throat is bacterial or viral.
| Criterion | Points |
|---|---|
| History of fever (>38°C) | +1 |
| Tonsillar exudates (white patches on tonsils) | +1 |
| Tender anterior cervical lymph nodes (neck gland pain) | +1 |
| Absence of cough (no cough = more likely bacterial) | +1 |
| Age 3-14 years | +1 |
| Age >45 years | -1 |
What the Score Means:
| Score | Probability of Strep (Bacterial) | Action |
|---|---|---|
| 0 or -1 | 5-7% | NO antibiotic. Symptomatic treatment only. |
| 1 | 10-15% | NO antibiotic. Symptomatic treatment only. |
| 2 | 20-30% | Consider throat swab / treat symptomatically |
| 3 | 38% | Consider antibiotic OR do rapid strep test first |
| 4-5 | >50% | Give antibiotic |
- Rosen's Emergency Medicine
STEP 2 - Viral vs Bacterial Features (Quick Bedside Check)
❌ VIRAL - DO NOT GIVE ANTIBIOTICS (treat symptomatically)
| Feature | Description |
|---|---|
| Runny nose / rhinorrhea | Hallmark of viral cold |
| Sneezing | Viral URTI |
| Cough | Especially dry/tickling cough |
| Hoarseness | Laryngitis - viral |
| Conjunctivitis (red eyes) | Adenovirus pattern |
| Gradual onset | Viruses develop slowly |
| No tonsillar exudates | Throat is red but no white patches |
| Low-grade fever or no fever | |
| Duration <3 days with improving trend |
Common causes: Rhinovirus, Adenovirus, Coronavirus, Influenza, Parainfluenza
✅ BACTERIAL - GIVE ANTIBIOTICS
| Feature | Description |
|---|---|
| No cough | Key bacterial clue |
| High fever >38.5°C | Sudden onset |
| Tonsillar exudates | White/yellow patches on tonsils |
| Tender swollen anterior cervical lymph nodes | Painful neck glands |
| Beefy red pharynx | Intense throat redness |
| No runny nose, no sneezing | Absent viral features |
| Centor score ≥ 3 |
Most common bacterial cause: Group A Beta-Hemolytic Streptococcus (GABHS / Strep pyogenes)
STEP 3 - TREATMENT GUIDE
A. VIRAL COLD & SORE THROAT (NO Antibiotics)
Symptoms & What to Give:
