Right. I'll wade in here with some factually correct information.
I'm a community pharmacist. I am 50% responsible in the eyes of the law for every prescription only medicine I dispense. If I require any further information from the patient before dispensing I will ask for it. I will not let something out of my pharmacy unless I am completely happy that it is the right medication, for the right patient at the right dose with no interactions with any existing medications. If I am unable to get to the counter (because I am already either engaged with another patient, on the phone to a patient or doctor, checking a prescription, sourcing a difficult to find medication, doing audit jobs for the nhs or any of the extra jobs my employer gives me - whilst listening to all the sales over the counter), then I will ask a qualified technician to counsel on my behalf.
This should, absolutely, occur in confidence. However in practice this is extremely difficult. Some years ago it was decided to open up pharmacies so that we are more accessible. however this means there is nowhere quiet at the counter and the whole counter is open plan. There is a consultation room but this is often in use. it is therefore impractical to ask patients to wait for the room to become available to ask one or two questions to confirm appropriateness of the prescription. (Surprisingly, patients are unwilling to wait any length of time for a prescription because 'it's only sticking a label on a box', how can it take 10 minutes?)
You would not believe the amount of time I've had to ask the next in line on the counter to please step back, because as soon as I open my mouth to speak to a patient the whole queue becomes extremely interested. (Nosy).
I, and my team, do try and keep our voices as quiet as possible, even though many of my patients are elderly and hard of hearing. If I have something sensitive to say I will always come out from the counter into the pharmacy, take the patient to one side and turn my back to the other customers whilst speaking quietly to maintain privacy.
I'd also like to say (as I have this at work all the time, because people think it's none of my business), that it absolutely is my business what other medications you take if you are buying medicines from behind the counter (pharmacy only medicines - sold under the supervision of a pharmacist - the key is in the name). This is because I'm 100% legally responsible for the sale of these. If you have an adverse reaction to anything sold, or an interaction with an existing medicine and you die as a result - I am negligent if I haven't asked, or had an assistant ask on my behalf. Result of this for me: at best - struck off and loss of job, at worst - prison sentence.
Phew! Bit of a rant there. Sorry.
