How to understand medicine label warnings
Red triangles, schedule H, NRx — a quick decoder for the warnings printed on Indian medicine packs.

The symbols on Indian medicine packs aren't decoration — they tell you how serious the prescription is.
Key symbols
- Red vertical line / Rx — prescription only
- NRx — narcotic, even stricter rules
- XRx — psychotropic, controlled supply
- Red triangle — sedatives, do not drive
Why this matters
If a pharmacist sells you a red-line medicine without asking for a prescription, that's a regulatory violation — and a signal to be cautious.
