I dunno about trazadone. I was taking it 100mgs a day. Took a months worth and didn't die.
"The average dose of trazodone is 150 mg to be taken once daily for depression treatment. This amount can be slowly increased to 600 mg daily if needed.
Lower doses of trazodone are used to treat insomnia, as the drug can produce sedation. Regardless of what it's used to treat, the trazodone overdose amount is anything above 600 mg within 24 hours.
With that said, the actual lethal dose of trazodone is not readily available. Many deaths associated with antidepressants like trazodone were due to mixing the drug with other substances, like alcohol or opioids."
Did damage my liver and kidneys a bit though. So I'd suggest against it tbh. Dunno much about abilify.
