Research on the safety of Seroquel shows that the lowest reported dose associated with fatality occurred after a person took 6,000 milligrams—or 7.5 times the maximum recommended dose.
However, additional case reports have shown patient survival after the ingestion of up to 30,000 milligrams. In a clinical trial, one death was reported after a person took 13,600 mg.
Seroquel overdose can be caused by taking an excessive amount of Seroquel alone, or in combination with other drugs.
One case series studying overdose incidents over five years identified the ingestion of high doses of Seroquel with opiates, amphetamines, benzos, cannabis, and barbiturates.
The OD amount for an antipsychotic like Seroquel varies from person to person. It will depend on how much tolerance someone has built, how long the drug was used, and what the patient was using with the drug. These factors play into what amount of it someone will have to take to reach an overdose. How much Seroquel will kill you wouldn't necessarily be the same as someone else.
A recorded instance of a woman surviving a overdose of Quetiapine; she made a full recovery within one day. Thus far, no long-term complications/ side effects have been reported. However, an antipsychotic drug like this one can be hazardous if not used right. Since most of the overdose symptoms are pretty severe such as a coma and seizures, a patient could suffer long-term complications or side effects.
I dont think its safe/peaceful. Id prefer another method….
edit: seroquel = quetiapine
