In case of a medical emergency while on Suboxone treatment, such as an overdose or severe adverse reaction, you should immediately call 911 or seek emergency medical assistance. It's crucial to inform the medical responders and healthcare professionals that you are undergoing Suboxone treatment so they can provide the necessary care and make informed decisions about your treatment. Additionally, you should keep a list of emergency contacts and the contact information for your Suboxone clinic or drug rehab facility readily available for quick reference in case of emergencies.
