Just read your message about problems with pharmacy. I have had problems with pharmacy and availability of Pramipexole. See link in Treatments & Therapies
Many of the larger pharmacies work with tight financial rules and do not like to have any spare meds waiting in cupboards. They also try to make sure they try to buy the best value meds available (which is understandable)
However, you should not have to put up with not getting your full prescription. I live a distance from my pharmacy and often ring them to make sure my meds are ready and avoid a wasted journey.
Either go and talk to your pharmacy and tell them about your regular requirements or if this does not work then ask advice from your Parkinson's Specialist Nurse. if you are able to email or telephone them then explain the issue and the Nurse may be able to contact the pharmacy on your behalf.
Your GP may be able to help as well.
I hope your problem gets better.
