Does Robaxin (methocarbamol) cause sleepiness?
Yes. Robaxin (methocarbamol) commonly causes drowsiness or sleepiness in some people. It’s also known to cause dizziness, which can make it feel harder to stay alert. Because of this, many labels advise against driving or operating machinery until you know how the medicine affects you.
What should you watch for if you feel sleepy after taking Robaxin?
People who feel sleepy on Robaxin may also notice dizziness, slowed reaction time, or trouble concentrating. If the drowsiness is severe, or if you have trouble staying awake, you should contact a clinician for guidance.
Can Robaxin sleepiness be worse with other medicines or alcohol?
Yes. Sleepiness and dizziness can be amplified by other central nervous system depressants, including alcohol and medications that cause sedation (such as some sleep aids, anxiety medications, and opioids). Combining these increases the risk of marked drowsiness and impaired coordination.
How long does Robaxin drowsiness last?
For many people, sleepiness tends to be strongest soon after taking a dose and may lessen as the medication level changes through the day. The timing can vary by dose, the specific formulation, and how your body metabolizes methocarbamol.
When to get medical help
Seek prompt medical advice if you have extreme drowsiness, confusion, fainting, breathing problems, or signs of an allergic reaction (such as swelling of the face/lips or trouble breathing).
If sleepiness is the problem, what can you do?
A clinician may be able to adjust the dose or timing, or recommend an alternative muscle relaxant. Until you know how Robaxin affects you, avoid driving and heavy machinery, and be cautious with alcohol and sedating medications.
