Quetiapine in blood: Your rxing practitioner most likely said it takes 4-6 weeks to see its full effect and therefore it will take at 4-6 weeks to get out of your system.

Sleep medicine doc: You should consult with a sleep medicine doctor. There are over 80 sleep disorders. I am boarded in psychiatry and sleep medicine, so I do both.

Can I mix seroquel (quetiapine) extended realese with the fast acting seroquel (quetiapine)??

Can I mix seroquel (quetiapine) extended realese with the fast acting seroquel (quetiapine)??

Yes.: Yes, but talk to your doctor first. I'm not sure what your rationale for combining regular with the extended release, but I could think of a few reasons that might make sense for some patients (taking advantage of different half-lives at different times allowing for varying duration of effects depending on time of day etc). ...Read more

Since I can't break a 50 mg seroquel (quetiapine) XR tablet in half is it possible to take it every other day as a way of tapering off since 50 is the lowest dose?

Seroquel (quetiapine) taper: Remember that whenever changing a psychiatric medication regimen, all medication changes should be carried out in collaboration with your treating doc. Never stop a psychiatric medication "on your own". If you and your doc do plan to taper off seroquel, (quetiapine) it is available in a non XR formulation which comes in smaller tablet strengths and can be split for better tapering. XR every other won't do :/ ...Read more

Talk to your...: Talk to your physician as soon as possible. It says you are depressed and insomnia can worsen depression. You may need another sleeping aide temporarily, or go back up on the quetiapine, or you may get used to the lower dose.

You and your physician can decide on the right course of action. ...Read more

Can I take seroquel (quetiapine) as a prn as im feeling a manic psychotic episode coming on. If I can what dosage until I see my psych.

Whoah! Call doc STAT: Seroquel (quetiapine) isn't a prn med & a patient shouldn't be self-medicating for mania. If you've been previously prescribed it & your providers are operating on the assumption you've reached a steady-state blood level, that's an issue too. Go to ER or contact on-call doc immediately if your mania is/was debilitating, especially if you've become psychotic in the past. Meantime, no alcohol/illicit drugs! ...Read more

What is the best dose of seroquel (quetiapine) if you are just using it for sleep?

What is the best dose of seroquel (quetiapine) if you are just using it for sleep?

Something else: I'm not wild about using it just for sleep, however, it is likely that your physician is using it to augment your antidepressant AND help you sleep. The effective dose range for augmentation can be fairly wide. There is no accepted number/dose for "sleep." ...Read more

Taking 100mg seroquel (quetiapine) at night. Will it work as a mood stabilizer at that dose?

Same deal: This is also something to bring up when you talk to your provider. Always ask these sort of questions when a medication or procedure is recommended. Doses are predicted by all sorts of factors including age/size/conditions, etc. Often they are slowly climbed to an effective level and maintained there.

How can you safely get off seroquel (quetiapine)? Is cold turkey really the only option once you are on the lowest dose?

Please review with your prescribing doc. ...Read more

Stopping meds: Dear MichaelB,

Unless you've had a problem stopping medication in the past (particularly quetiapine aka Seroquel) it is usually ok. Some people have rebound insomnia, or a recurrence of symptoms, which can be irksome and occasionally serious. I'd make sure the prescribing clinician is aware you are stopping before doing so, and ask her or him about your concern as well. ...Read more
