My mother was taking Seroquel for the delusions she was having. She was taking 200 mg twice a day. She has fallen into a "donut hole" with her Medicare and the cost of the medicine quadrupled in price! Her doctor changed her to Seroquel XR at the suggestion of the pharmacy because the cost would be less, and she would be taking less pills in a day. The Seroquel XR is supposed to be comparable to the regular Seroquel, only release the medicine throughout the day. She has been extremely agitated and the delusions have increased since the change. The doctor has increased the mg but she is still not doing as well as she was. Will the XR work as well as the regular? How does the extended release compare to the regular one?
