Summary
buprenorphine (pain)

Belbuca is a medicine used to treat severe, long-lasting pain. It contains buprenorphine, a type of opioid pain reliever.

What It Treats
buprenorphine (pain)

Belbuca is used to manage severe, ongoing pain that needs an opioid medicine. It is for pain that cannot be well-treated with other options, like immediate-release opioids. Because of the risks of addiction, abuse, misuse, overdose, and death, Belbuca should only be used if other treatments don't work, aren't tolerated, or aren't enough to manage your pain.

pregabalin

This medicine is used to treat nerve pain caused by diabetes, shingles, or spinal cord injury. It can also help with fibromyalgia, a condition that causes widespread pain. Pregabalin can also be used with other medicines to treat partial-onset seizures in adults and children as young as 1 month old.

How It Works
buprenorphine (pain)

Belbuca contains buprenorphine, which is a partial opioid agonist. It works by attaching to certain receptors in the brain and body. This helps to decrease the feeling of pain.

pregabalin

Pregabalin works by binding to certain areas in your brain and spinal cord. This action helps to reduce the release of chemicals that send pain signals. By reducing these signals, pregabalin can help to lessen pain and control seizures.
