Besides the risk of Suboxone dependence and addiction, the use of this medication can also cause some serious health effects. The most worrisome side effect of Suboxone is respiratory depression (slowed breathing). This risk is especially high when Suboxone is taken with other medicines like benzodiazepines (Xanax, Valium, Ativan).
Also, in some people, Suboxone can lead to liver problems, a drop in blood pressure, or symptoms of opioid withdrawal. An allergic reaction to Suboxone can produce symptoms such as hives, rash, facial swelling, wheezing, low blood pressure, and loss of consciousness. A Suboxone allergic reaction is a medical emergency and warrants immediate medical attention.
