Signs that your buprenorphine/naloxone (Suboxone) dose is too low may depend on the reason you are taking Suboxone. If you are taking Suboxone for chronic pain and do not take other opioids, you may need to increase the dose simply because your pain is not well controlled. The lowest dose of Suboxone for chronic pain is as low as 2 mg three times a day, but some people may require higher doses. Suboxone given for chronic pain is usually dosed three times a day.
For opioid use disorder, your Suboxone dose may be too low if you experience symptoms of withdrawal. Some common symptoms of withdrawal are a craving/desire to take opioid medications, anxiety, tremors, sweating, nausea/vomiting, abdominal cramping, and diarrhea.
