Methocarbamol Tablets do not have any effect on pets who are suffering from anxiety. This medicine only cures pets who are suffering from skeletal muscle pain. Methocarbamol only helps in the alleviation of the factors or conditions that may result in muscle spasms in your pets. The medicine can sometimes cause dizziness or drowsiness to your pets but that cannot be mistaken as a mind relaxing agent or anti-anxiety medicine.
