Yes, nurses can take Suboxone.
All patients taking Suboxone are protected under the Americans with Disabilities Act. This law states that employers cannot discriminate against or fire people who are taking medications that were prescribed by a doctor, including Suboxone.
This applies to nurses as well. Nurses are entitled to use Suboxone just like any other patient. As always, they should be careful to take their Suboxone as prescribed and to make sure they are not overly sedated when taking Suboxone while at work.
