Tips for Exam:
- Always quote drug + dose + duration + route
- Know first-line vs second-line for each condition
- Learn differentials: Psoriasis vs Eczema vs Tinea; Viral vs Bacterial conjunctivitis; Acute vs Chronic glaucoma
- For surgical conditions: always mention conservative → medical → surgical hierarchy
- For OPD prescriptions, always add PPI if prescribing NSAIDsHere is a summary of what's covered in the reference above:
