I went to take my quetiapine XR a few hours ago, only to realise that the GP has prescribed 150mg, rather than 50mg. I've completely run out. What can I do? Could the pharmacist do anything? Or anyone else? I can increase my regular quetiapine (I usually take 150mg of that on a night), but I'm not sure whether it will keep me OK until Monday. I tend to be super-sensitive to small changes in doseage and I think I'll notice it's gone. Help, anyone!?
