Head-to-head comparisons of medication uses, side effects, warnings, and more.

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.
