Key takeaways
Diazepam (Valium) and orphenadrine are both used to treat muscle-related issues, but they have some key differences. Diazepam is a benzodiazepine that treats anxiety, alcohol withdrawal, muscle spasms, and seizures. It works by increasing gamma-aminobutyric acid (GABA) levels in the brain. Orphenadrine, on the other hand, is a muscle relaxant used specifically for relieving muscle pain and discomfort. Its exact mechanism is unclear, but it blocks nerve signals between the spinal cord and muscles. Diazepam is a controlled substance with a risk of misuse and dependence, while orphenadrine is not a controlled medication but can still be misused. Diazepam is available in both tablet and liquid forms and is taken multiple times a day. Orphenadrine is taken as a tablet twice a day or as an injectable under the supervision of a healthcare professional. Common side effects of diazepam include sleepiness, dizziness, and muscle weakness, while orphenadrine can cause dry mouth, headache, and drowsiness.
Orphenadrine citrate is a muscle relaxer that's used to relieve muscle pain and discomfort. It's often used together with other pain-relieving methods, such as resting and physical therapy. Orphenadrine is available as a tablet that's taken by mouth as well as an injection that's administered by a healthcare provider for certain situations. Side effects can include dry mouth, headache, and drowsiness. Orphenadrine is a generic medication; its brand-name version, Norflex, is no longer available.
