Is your pet suffering from muscle spasms? Methocarbamol is an FDA approved medication your veterinarian may prescribe as a muscle relaxant to treat spasms in dogs and cats. It can help conditions such as acute inflammation, intervertebral disc disease, back problems, and traumatic conditions or tremors brought on by tetanus or poisoning. It helps reduce skeletal muscle hyperactivity without changing the normal muscle tone. The full effects of the medication can take place within 1 to 2 hours of dosage, providing relief to your pet.
Methocarbamol is safe to use along with nonsteroidal anti-inflammatory medications used for treating muscle spasms. Since methocarbamol is a central nervous system depressant, it should not be combined with other medications that depress the CNS. Methocarbamol is also used, and FDA approved for treating horses with acute inflammation and traumatic conditions of the muscle.

Drug & Food Interactions

Drug Interactions: If your pet is on any of the following medications you should use methocarbamol with caution:

  • CNS depressants: When combined with methocarbamol, depression may occur.
  • Mirtazapine: When combined may increase the CNS depressant effect of mirtazapine.
  • Pyridostigmine: When combined the therapeutic effect of pyridostigmine may lessen.
  • Selective serotonin reuptake inhibitors (SSRIs; e.g. fluoxetine, paroxetine):  When combined can enhance the side or toxic effects of SSRIs.
