It all depends really on what happened and how much fuss you kick up:
If the doctor prescribed one thing and the pharmacy gave another then you are entitled to the correct thing, complain at the pharmacy to get the right item (but not a refund).
If the doctor prescribed what they thought was right and it was suitable given the scenario but simply hasn't worked/ had side effects, then no.
If the doctor meant to prescribe one thing but cocked up and gave you something else (which the pharmacy dispensed in good faith), then not really, but complaining to the surgery may get you your money back.
If you want to PM me the details then I can guide you further![]()
Thanks will do.
