Cyclobenzaprine for dogs: Treating muscle spasms and severe pain

Cyclobenzaprine is a muscle relaxer that can be used off label for dogs with muscle spasms or severe pain. However, the safety of cyclobenzaprine for dogs has not been established.
If you’ve ever sprained your ankle or strained a muscle, you might be familiar with the medication cyclobenzaprine. Cyclobenzaprine, sold under the brand name Flexeril or Fexmid, is a prescription drug and muscle relaxant that manages muscle spasms and blocks pain by inhibiting nerve impulses being transmitted to the brain. While this drug is often prescribed to humans, you may be surprised to learn that it may also be prescribed to your furry friend.
