A prescription is a slip provided by the doctor to a patient after the consultation. A prescription will have all the medicines written on it which are required for the patient.
Prescription is mandatory for most medicines as they can’t be dispensed directly to the customers.
Medicines will have a different impact on different human bodies, so there is a need for experts who have a thorough knowledge of the human body and medicines for dispensing the medicines.
Don’t worry, there are Doctors and Pharmacists to take of everything.
