Suboxone is a combination drug product useful for helping people addicted to opioid drugs to stop using these substances. The medication includes buprenorphine, classified as a partial opioid agonist, and the antagonist drug naloxone, which counteracts opioid overdose symptoms. Buprenorphine has a limited opioid effect. While it prevents withdrawal, it causes only mild euphoria compared to the intense euphoria associated with drugs such as oxycodone, morphine and heroin. The U.S. Food and Drug Administration has approved Suboxone tablets for long-term maintenance therapy, so opioid addicts can resume and maintain normal, productive lives. Nevertheless, some dangers are linked to Suboxone.

Suboxone can cause drowsiness, dizziness, impaired thinking and slow reaction times. It also may increase the impact of drugs with similar effects, according to These drugs include alcohol, anti-anxiety medications, antidepressants, antihistamines, sedatives, tranquilizers, certain pain relievers and muscle relaxants. This can make driving or operating machinery dangerous.

Overdose, the official website for the drug product, recommends that doctors use an aggressive approach to dealing with opioid addiction when using Suboxone. The risk of severe negative effects, including overdose, is higher if the patient does not receive enough buprenorphine and continues to take other drugs. Suboxone overdose can be fatal, particularly if the patient injects this drug while also taking sedatives, tranquilizers or alcohol. Unconsciousness, severe respiratory depression and death can occur. Life-threatening overdose also can result from taking excessive amounts of Suboxone orally or combining oral Suboxone with alcohol, sedatives, tranquilizers, certain antidepressants and other opioid medications.
