Brief Answer:
Very unlikely

Detailed Answer:

Hello,

The toxicity with Seroquel is very rare although can occur in extreme cases. For a person of 70 years or older anything beyond 800 mg is toxic dose and can cause serious effects such as sedation, cardiac arrhythmia, coma and death can occur.

However as per the available data the toxic dose has been reported from 2.7 to 14 kg in different individuals (young).

I hope this helps you.
Feel free to write back to me if you have more questions.
Thanks and regards.
