Will Intake Of Methamphetamine Eliminate Naltrexone Out Of System?

It would stay in body for 13 hours
Detailed Answer:
HI
Thanks for using healthcare magic. I, Dr Abhishek Kapoor, would help you in this query.
Elimination half life of naltrexone is 4 hours and its metabolite is 13 hours. If you have taken it at 11 am in morning, then it would show its effect till 12 at night and in between, if you take heroin, you would not get high. Naltrexone is opioid antagonist and it blocks the receptor completely, due to which even after taking heroin or any opioid, you would not get any response.
You can take heroin tomorrow, but after that, do not take naltrexone, otherwise, you would get withdrawal. There should be 7 days abstinence period between heroin intake and beginning of naltrexone. If you try naltrexone in between after heroin intake, you would get severe withdrawal.
Currently, you have only one option, just go to emergency room and get some symptomatic treatment.
If you want to take meth, you can take, but it would not speed up it metabolism.
In case, you have any more query, you can ask.
