<s>[INST] Q1: what will happen if I dont take my prescribed dose of seroquel xr, and I ve been told by my doctor to take my dose (50mg+50mg+400mg) about 6 or seven o clock each day, if I miss the dose and don t take it till tomorrow evening, how will it affect me?? and what will it do to my brain\body. note: I have not taken my dose since half eleven last night. [/INST] Hi,    I understand your concern.    IT is good to take the prescribed  dose of Seroquil regularly. A regular follow up is advised to readjust the dose.     A sudden break in taking routine dose for several days is likely to cause withdrawal symptoms with sometimes relapse.     But missing a single dose does not cause much difference to body/brain.     When a dose is missed, it should be taken as soon as remembered. But if it  is  nearer to next scheduled dose, it should  be dropped.     Thanks. </s>
