The doctor has had me on Suboxone for over a year what are the long term side effects from it?

See below. If Suboxone is weaned slowly under the supervision of a physician you should not expect any specific long-term side effects.
Year of use. If you are on this medication for pain, it often works well. If you were started on the medication to get you off of another pain medication, you may want to discuss with your doctor tapering you off the medication. Many addictionologists will try to get you off the medication with in a few weeks, as most patients do not need to stay on opioid pain medication.
Suboxone. The serious reactions include respiratory depression, respiratory arrest, bronchospasm, anaphylaxis, angioneurotic edema, hypotension, bradycardia, seizures, hepatitis, hepatotoxicity. Then there are the common reactions like headache, insomnia, pain, withdrawal symptoms, nausea, depression, dizziness, chills, vomiting, anxiety. These are reported side effects which you may never have.
It Depends. With any treatment, one should weigh both the risks and benefits. Also, and perhaps particularly for opiate addiction where relapse can be fatal, one needs to weigh the risks and benefits of not having treatment (suboxone). Factors which should considered in deciding how long to stay on Suboxone include the duration of the abuse, the daily dose, the route (iv?,), family history as well as others.
There are several. Side effects possible include constipation, sweating, tiredness, drowsiness, depression, hepatitis and addiction. However. Many patients on long term Suboxone report no significant side effects.
None, really. As a prescriber of Suboxone for the last 9 years, my experience has been that there are no long term side effects. That is the just one of the many benefits of Suboxone and why the fda granted its use for maintenance (indefinite use), not detox. Just like most other diseases that we cannot cure, but only manage safely. Continue the suboxone, enjoy sobriety and live your life!
