Gabapentin is a medicine that can treat nerve pain and seizures. It works by calming overactive nerves in the body.
Nucynta is a strong pain medicine. It is used to treat severe acute pain when other pain medicines are not strong enough.
Gabapentin is used to manage nerve pain after shingles in adults. This is called postherpetic neuralgia. It is also used with other medicines to treat partial seizures in adults and children ages 3 and older who have epilepsy.
Nucynta is used to manage acute pain in adults and children (6 years and older weighing at least 88 pounds). This medicine is for severe pain that requires an opioid pain reliever. It is used when other pain treatments are not adequate.
Gabapentin affects how nerves send signals to the brain. It is thought to work by decreasing the activity of overexcited nerve cells. This can reduce pain and prevent seizures.
Nucynta works in two ways to relieve pain. It acts on opioid receptors in the brain to reduce pain signals. It also prevents the reuptake of norepinephrine, which can also help reduce pain.
