Methocarbamol can cause drowsiness, dizziness and blurred vision. It is very likely that your girlfriend has had these side effects. This has caused anxiety which has led to slurred speech and disorientation.
There is no need to panic over this. This is certainly not a life threatening condition and she will get back to normal very soon. You should now contact her doctor who prescribed the medicines and describe her symptoms to her. You can contact over phone, or contact the clinic. She should not take the medicine anymore. Try to get her to relax. Methocarbamol does not cause any life threatening complications, so by relaxing this episode will likely go away.
Of course, if you find her symptoms worsening over 30 minutes, then you need to go to the ER. There could be some other associated condition which is causing this, but Methocarbamol is unlike to cause this.
