Actually be glad you are only on 150; the price increases proportionally! I am on 600 and the monthly cost is over $700. Thank GOD we have good insurance at the moment. I have built up a reserve of Seroquel just in case. I ask my PDOC for samples when I see him every couple of weeks. I think there some connection between samples given and the drug company. UNFORTUNATELY I have not found an affordable Seroquel replacement.
