Now once we issue a prescription, irrespective of what the brand is, many chemists dispense what they have and sometimes based on the margin available on the product. For example, an antibiotic, an original molecule from a reputed brand(Augmentin) will be more expensive than the other product from a fairly new company. By and large, most doctors prescribe what they are familiar with and what has given results in their previous patients. For instance, there are many brands of paracetamol but only a few at the same strength gives you results than other.
So, yes they can change and site the above reason as an excuse. Stick to your regular doctor and a regular nearby pharmacy wherein both know you and the chances of buying a substandard product will be less likely.
Do what inspires you !!

Even this challenging situation would ease
Sir, the problem is although the combination or the generic name is the same, the quality matters a lot. They are many companies of antibiotics but any doctor worth his salt and pharmacist true to his conscience will tell you, brand X is better, although it comes with a little higher price tag, the quality is good and it works better than brand Y which is a cheaper brand. in patients who are sick and critically ill in ICU, getting the medication that has the genuine molecule becomes vital to the survival. By trial and error and with the passage of time you can notice that your family doctor sticks to a particular brand as he/she would have noticed the good results from previous patients. The sad part is substitution is also being done by professional for personal gain
