I am pregnant and addicted to herion and percocet 30mg. I want to withdrawal from them and want to go to the emergency room for help. What will they do for me? Is it worth even going there?

I don't know what ER will do for you but whatever you need to do to get help is worth doing.

Try searching for child and family services in your area... IDK what ER will/would/might or might not do, but I would reach out to a family service center familiar with detox and how to get the help you need and want... they will be able to point you in the right direction. If it is the weekend, and you need immediate help, then yes, ER, but... they will not be able to help you, long term.

The ER is only to help you in an emergency. You need long term treatment. You need to look for treatment centers in your area.

A pregnant woman can take methadone. Please call around to find a clinic. Try the hospital nurses' station on the OB/GYN floor for a start.
