Relaxes your muscles.

Robaxin (methocarbamol) effectively relieves muscle spasms, but it can cause drowsiness and interfere with your ability to drive.

Works well to control muscle spasticity.

Gablofen (baclofen) is effective for long term spastic conditions, such as multiple sclerosis, spinal cord injury, and others. It is administered intrathecally by a pump connecting to your spine.

Upsides
  • Effective for relieving muscle spasms and pain.
  • For those with trouble swallowing, the pills can be crushed and mixed with food or liquid.
  • Available in generic form and cheaper than other muscle relaxants.
  • Might be a better treatment option for those with a history of drug abuse since Robaxin (methocarbamol) has a low potential for causing addiction and dependence.
  • Gablofen (baclofen) is the agent of choice for treatment of muscle spasticity.
  • Gablofen (baclofen) has fewer side effects than the oral form, since higher levels can be delivered to the spine at lower doses.
Downsides
  • Robaxin (methocarbamol) can make you sleepy so you might not be able to drive or do certain activities requiring concentration.
  • Need to take a few times throughout the day to maintain effect.
  • Might not be safe to use in people age 65 or older due to increased sensitivity to side effects such as drowsiness.
  • Researches do not know the safety and effectiveness of Robaxin (methocarbamol) in people under age 16.
  • Can be dangerous when used together with other medicines that also cause drowsiness such as narcotics.
  • Gablofen (baclofen) can cause sleepiness and drowsiness.
  • Stopping Gablofen (baclofen) right away can be life-threatening, so a doctor would need to help you stop it.
  • Gablofen (baclofen) has to be started in the doctor's office. You or your caregiver need to be trained on how to use the pump.
