Now I have enough information to give a thorough, practical answer. Let me compose it.
Common Conditions at RHTC and Their Symptomatic Treatment (Age-Wise)
As a rural intern, the bulk of your OPD will be these conditions. They are grouped by system and each has age-stratified treatment.
1. ACUTE DIARRHEA / GASTROENTERITIS
The #1 cause of morbidity in rural India, especially in children under 5.
Cornerstone: ORS + Zinc
| Age | ORS (each loose stool) | Zinc |
|---|
| < 6 months | 50-100 mL | 10 mg/day x 14 days |
| 6 months - 2 years | 100-200 mL | 20 mg/day x 14 days |
| 2-10 years | 100-200 mL | 20 mg/day x 14 days |
| > 10 years / Adults | As much as tolerated (200-400 mL) | Not routinely needed |
- ORS recipe if packets unavailable: 1 litre boiled water + 6 tsp sugar + 1/2 tsp salt
- Antibiotics: Only for cholera-suspect (tetracycline 250 mg QID x 3 days in adults; in children use cotrimoxazole) or bloody diarrhea/dysentery (ciprofloxacin 500 mg BD x 3 days in adults; nalidixic acid in children)
- Metronidazole 400 mg TDS x 5-7 days if amoebiasis/giardiasis suspected (loose, foul-smelling, frothy stools)
- DO NOT give anti-motility agents (loperamide) in children
2. ACUTE RESPIRATORY INFECTIONS (ARI / URTI)
Includes common cold, pharyngitis, tonsillitis, sinusitis - very common year-round.
Symptomatic Treatment
| Age | Paracetamol (fever/pain) | Antihistamine + Decongestant | Notes |
|---|
| < 2 years | 10-15 mg/kg/dose every 4-6h | Avoid OTC cold syrups | Saline nasal drops, breastfeed |

- Antibiotics only if bacterial infection suspected: fever >3 days, purulent exudate, severe throat pain, ear pain (otitis media) - use Amoxicillin 250 mg TDS (children: 25-40 mg/kg/day in 3 divided doses) x 5-7 days
- Pneumonia (tachypnea + fever): refer or start Amoxicillin 40 mg/kg/day; in adults - Amoxicillin 500 mg TDS x 5-7 days; refer if severe (chest indrawing, cyanosis, SpO2 < 94%)

Practical Tips for Your Posting
- Always confirm malaria with RDT before treating - do not treat empirically without testing
- ORS first in every diarrhea case - antibiotics are rarely needed
- Zinc for 14 days after every diarrheal episode in children under 5
- Deworming every 6 months - piggyback it onto every child under-5 visit
- Malnutrition screening - use MUAC tape at every under-5 visit (< 11.5 cm = SAM; 11.5-12.5 cm = MAM)
- WIFS scheme - weekly iron-folic acid for adolescent girls; always record in register
- Primaquine is contraindicated in infants, pregnancy, and G6PD deficiency
- Metformin start low and go slow (500 mg OD for 1-2 weeks first) to reduce GI side effects
- Complete family treatment for scabies - treating only the index case leads to reinfection
- Document everything in the OPD register - it is required for RHTC records and national health data
