indications for Methocarbamol

Methocarbamol 500mg tablet is indicated in the treatment of acute inflammatory and traumatic conditions of the skeletal muscle. It is commonly used to manage muscular spasms in dogs, cats and horses. Methocarbamol is found to be effective in treating conditions like intervertebral disc syndrome, synovitis, convulsions, fibrositis, myositis, compressive myelitis, spinal cord injury and insecticide poisoning among others. It could be used in combination with medications commonly used to treat these conditions like adrenal corticosteroids, without any adverse side effects.


Methocarbamol 500mg is a prescription medication, which should not be started without the consent of a licensed veterinarian. Stay clear from administering Methocarbamol in pregnant animals as its safety has not been fully verified. Animals with known or suspected renal pathology or those which are allergic to the drug should not be treated with this medication. In case the animal fails to respond to the medication even after five days of the initiation of treatment, the treatment mode should be reconsidered. It could adversely interact with certain muscle relaxants or sedatives; so make sure that the medication history of the pet is discussed with the vet before starting the treatment.


The usual dose of Methocarbamol for dogs and cats of all sizes is typically 20-30mg per pound of the animal's body weight every 8-12 hours for the first day followed by 10-30mg per pound of body weight every 8-12 hours thereafter.
