No - not until 2017 will it go generic, according to Wikipedia:
"AstraZeneca submitted a new drug application for a sustained-release version of quetiapine in the United States, Canada, and the European Union in the second half of 2006 for treatment of schizophrenia. AstraZeneca will retain the exclusive right to market sustained-release quetiapine until 2017. "
I guess the doctor is under orders to keep costs as low as possible. You may do fine on the regular Seroquel - so he probably has to try it on you. If things don’t go well - I bet he would put you back on the XR.
Copies of both standard Seroquel and Seroquel XR, an extended release version of the drug, will be available for use in the NHS at lower costs than AZ’s branded products.
The generic cost of a 25mg dose of regular quetiapine will be £6.08, compared to £30.50 for AZ’s product. The price difference is less pronounced for the extended release formula, however, with Teva offering a 50mg dose for £50.75 compare to AZ’s price of £67.66.
“This decision only applies to the UK, with AZ recently winning a court decision validating the Seroquel XR formula in the Netherlands. Decisions are still pending for concluded cases in the US and Spain.”
And don’t wanna make you paranoid , your regular doc should have no say on what psych med you are prescribed. Quite simply he should prescribe as per written instructions from your psychiatrist… Local GP Practices can be affiliated with certain pharmacies , and it would suit the pharmacy to be given you something cheaper…Again get somebody to help you out .
