Lloyds pharmacy is best, you can use a different name, just print out the invoice and they provide it. Via the internet and physical collection at the chosen pharmacy. Can't be traced back to NHS record, payment mechanism and the doctor records are on independent system. Normally prescription is ready in 2-3 hours max doing it on line. They normally stock 50mg but not 25mg so if you want it guaranteed ring up the closest pharmacy first before going through the process. If you really paranoid Sainsbury provide a £50 nameless mastercard that you can use as well. I normally get 16/32 as a one off, will last for ages. Get the 50mg and split in half if you only need 25mg, its cheaper.
