Registered pharmacies should provide comprehensive pharmaceutical services and supply emergency medicines without delay. Pharmacists must prevent errors in dispensing, preparing, and supplying medicines and maintain a professional appearance. Pharmacists should properly receive, read, check, and fill prescriptions, taking all possible care in handling drugs and using only standard quality medicines. Pharmacists should provide full facilities for apprentice training and engage in good dispensing practices, proper labeling, and fair trade without misleading advertising or price gouging. Pharmacists must not diagnose or prescribe medicines themselves but can provide first aid in emergencies.
