Stress and changes to the body can often cause elevations in blood pressure. In fact, withdrawal itself can cause Blood pressure increases. If you do notice elevations in blood pressure while going through withdrawal and starting Suboxone, this is the much more likely explanation rather than the medication itself, which is not known to be associated with elevated blood pressure.
If you experienced blood pressure increases when you started Suboxone, it will likely be short-lived, and likely more due to the stress and withdrawal itself than to the medication. Always consult your provider closely as you first begin Suboxone. They will likely check your blood pressure and other vitals signs prior to visits to ensure that you are as healthy as possible while taking this medication
Your Suboxone dose doesn't cause your high blood pressure. However, your withdrawal process can raise your blood pressure readings.
Withdrawal from opioids is stressful, and your entire body is under pressure. Your heart beats faster, your blood vessels tighten, and your blood pressure rises. Those numbers will remain elevated until your withdrawal is finished.
Opioid withdrawal can last 10 days or longer, but most people feel their worst during the first few days.
If you're enrolled in a treatment program for opioid use disorders, your team will watch your blood pressure readings carefully and offer medical treatment as needed.
