alcohol consumption.

Usage

Following the dosage instructions of your doctor is the best way to use any medication. If you are unsure or do not remember the instructions then you may read the medicine label for more detailed information. Revia should not be taken until the naltrexone challenge test is negative.
You may choose to take REVIA with a meal to avoid an upset stomach or without one.
It is strictly necessary to be negative in the naltrexone challenge test before taking REVIA.

Missed Dose

Despite your best attempts at remembering, if you still miss out on a dose, then take it as soon as you remember about it.
