Key takeaways
Methocarbamol (Robaxin) and orphenadrine (Norflex) are both muscle relaxants used to relieve muscle pain and discomfort, but they have some differences. Methocarbamol is taken 3 to 4 times daily, while orphenadrine is taken only twice a day. Methocarbamol can be taken as a tablet or injection, and it starts working within 30 minutes. Orphenadrine, available as a generic, can also be taken as a tablet or injection and starts working within an hour. Methocarbamol is less likely to cause drowsiness compared to other muscle relaxers, whereas orphenadrine can cause dry mouth, sleepiness, and headache. Orphenadrine has more restrictions, such as not being suitable for people with glaucoma or certain stomach problems, while methocarbamol is not recommended for older adults due to higher risk of side effects. Both medications should be used with caution and under the guidance of a healthcare professional.
