If you are a student you might be well aware of the abbreviations as they are often asked in exams and terms in Pharmacy schools and colleges.
Later one when we step behind the counter for refilling these prescriptions we might face a lot of difficulty to understand what a doctor wants to write for his patient.
All of these abbreviations can be learnt in an easy way but with a practice and always double checking with Pharmacists in charge. For a head start you can refer to the table below.
This can be taken as a beginner's guide for fresh pharmacy graduates, technicians, nurses to help them understand for a proper medicine administration.
