Key takeaways
Cyclobenzaprine (Flexeril) and gabapentin (Neurontin) are both medications that can help with pain, but they work in different ways and treat different types of pain. Cyclobenzaprine is a muscle relaxant used to relieve muscle spasms and discomfort, while gabapentin is an antiepileptic medication used to treat nerve pain from shingles and as an add-on treatment for partial seizures. Cyclobenzaprine is available as immediate-release tablets and extended-release capsules, and it is typically taken up to three times a day. Gabapentin is available as tablets, capsules, and liquid, and is usually taken three times a day. Cyclobenzaprine is not a controlled substance, but gabapentin is controlled in some states due to potential misuse. Common side effects of cyclobenzaprine include drowsiness and dry mouth, while gabapentin often causes dizziness and sleepiness. Cyclobenzaprine can interact with antidepressants and cause serotonin syndrome, whereas gabapentin can interact with medications like benzodiazepines and opioids, increasing the risk of slow breathing.
