The U.S. Food and Drug Administration (FDA) doesn't include psychosis on its list of known Suboxone side effects. But case reports suggest some people get it while taking the drug, and others while they withdraw from it.
Psychosis refers to a mental state where there is a loss of contact with reality. Symptoms can include delusions (false beliefs) and hallucinations (seeing, hearing, or feeling things others do not).
Here’s what you need to know about psychosis as it relates to Suboxone.
Psychosis from Suboxone would be an extremely uncommon symptom of Suboxone use. Psychosis could theoretically occur in two situations:
Presumably, a patient who developed psychosis after starting Suboxone would likely have a history of psychosis or other severe mental health disorder. It would be very unusual for Suboxone alone to cause psychosis without other underlying mental health conditions. Some patients do experience tactile and visual hallucinations while taking their Suboxone doses, although this is also exceedingly rare. 
Some patients experience a sudden onset of psychosis when they stop taking Suboxone. Typically, the problem appears when people stop taking their doses abruptly. Returning to their medications makes the issue disappear. Again, this is much more likely if the patient has a history of mental health disorders or previous history of psychosis.
In either case, abruptly stopping Suboxone isn't smart. Sudden discontinuation can lead to psychosis or other withdrawal symptoms. Always talk to your doctor before you stop taking any prescribed medication.
Many things can cause psychosis. It is a common symptom of some mental illnesses, like bipolar disorder and schizophrenia. Psychosis can also be triggered by using drugs or medications, including alcohol, marijuana, hallucinogens, opioids, or antidepressants/antipsychotics.
In many cases, particularly in patients who have underlying mental health conditions, drug and opioid use can precipitate psychotic symptoms. In these cases, MAT including Suboxone may be particularly important for helping patients to avoid opioid misuse and to help improve the symptoms of psychosis.
If you have a history of psychosis, Buprenorphine-containing medications like Suboxone are very safe for you to use. In fact, preventing opioid misuse will likely improve your overall mental health and avoid repeat episodes of psychosis.
If you have any concerns about taking Suboxone with a history of psychosis, talk to your doctor. They can provide you the information you need as you move forward with Suboxone treatment.
