dear doctor
Hi, Seroquel (quetiapine) and Laura (lurasidone) are two different Chat Doctor.  I expect Seroquel to be cheaper than Laura. In addition, the generic form of Seroquel is also available, which will be even cheaper. But you'll need to contact your doctor and discuss this. You mentioned not receiving much benefit from your medicines. Since you are depressed, you will need treatment with anti-depressants. Antipsychotics like Seroquel can augment the action of antidepressants but not replace them. There are things other than medicines that also help, like cognitive therapy etc. Please do not lose hope. Inform your doctor and family members immediately if you feel a desire to harm yourself. Best wishes.
