metaxalone
Metaxalone is a muscle relaxer. It's used to treat muscle pain and discomfort that's not chronic or long-lasting. This medication is thought to relieve muscle pain by relaxing your nervous system in the brain. Metaxalone is typically taken by mouth three or four times a day. It commonly causes drowsiness and dizziness as side effects. It's best to avoid drinking alcohol while you're taking metaxalone because alcohol can interact with this medication and worsen side effects.

Pharmacist tips for Metaxalone
- You can take metaxalone with or without food. Be sure to be consistent with the way you take the medication. Keep in mind that your body might absorb more of the medication if you take it with a full meal and you might be more likely to have side effects from metaxalone like dizziness and drowsiness.
- Side effects like dizziness and sleepiness are common. Metaxalone can also affect your ability to focus and concentrate. Avoid driving or performing any activity that requires a lot of attention until you know how this medication affects you.
- Don't drink alcohol while you're taking metaxalone. Alcohol can make side effects worse.
- Let your prescriber know if you take other medications that can make you dizzy or drowsy, such as opioids, benzodiazepines, or sleep aids. Taking these types of medications with metaxalone can raise the risk for life-threatening drowsiness or trouble breathing.
- Tell your healthcare team and pharmacist about all the medications you're taking, including over-the-counter products. Metaxalone can interact with certain medications and lead to serious risks. Interactions with antidepressants can lead to a rare but life-threatening condition called serotonin syndrome.
Common questions about Metaxalone
High blood pressure isn't a common side effect of metaxalone. If you notice that you have unusually high blood pressure after you take this medication, it could be a sign of a serious condition called serotonin syndrome. This is rare, but your risk is greater if you take metaxalone with certain antidepressants. Make sure your prescriber and pharmacist knows about all the medications you're taking to check that they're safe for you to take.
Yes, sleepiness is one of the more common side effects of muscle relaxers like metaxalone. But this medication is the least likely of the muscle relaxants to make you sleepy. Still, don't drive or perform other activities that require you to be alert until you know how metaxalone affects you.
No. Metaxalone isn't an opioid pain medication (also known as a narcotic). It's also not a controlled substance because there's no risk for addiction or dependence. Metaxalone is a muscle relaxer, which has its own set of risks and warnings. Discuss with your healthcare team about the risks and benefits of taking metaxalone before you start the medication.
This can vary from person to person. Most people start to feel some effects within an hour of taking metaxalone. You should feel the full effects within a few hours after your dose.
Metaxalone is a pretty short-acting medication, so you can expect the effects of the medication to wear off after about 4 to 6 hours. Your age, gender, and whether you took your dose with food can also affect how long it takes for Metaxalone to wear off. For example, the effects might linger around longer for females and the effects might go away faster if you take the medication with food.
Yes, you can take Tylenol, also known as acetaminophen, with metaxalone if you're having general pain or fever along with your muscle spasms. The two medications don't seem to interact with each other.
Yes. Metaxalone tablets are scored, which means they have an indented line down the middle of the pill. Scored tablets are typically okay and safe to cut in half. Speak with your prescriber first if you plan to split tablets in half to make sure it's appropriate for you. Be sure to use a pill splitter from the pharmacy to safely cut the tablets along the score line if you need to cut your metaxalone tablets in half.
Although constipation isn't a commonly reported side effect of metaxalone, it can happen with certain muscle relaxers. Ask your prescriber or pharmacist to review your current medication list if you start having bothersome constipation. They can help determine whether the constipation is caused by metaxalone, another medication, or another medical condition.

Risks and warnings for Metaxalone
Metaxalone can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Serotonin syndrome
- Risk factors: Taking other medications that can affect the serotonin levels in your brain
There have been reports of serotonin syndrome in some people who take metaxalone alone or with certain other medications. Serotonin syndrome is a rare, but potentially life-threatening condition that happens when there's too much serotonin in the brain. Serotonin is one of the chemicals in your brain responsible for your mood.
Your risk for serotonin syndrome goes up if you use metaxalone with other medications that affect serotonin levels, such as antidepressants, triptans for migraines, and St. John's wort. Tell your healthcare team and pharmacist about all the medications and over-the-counter products you take so they can check for any interactions with metaxalone.
Call your healthcare team or get medical help right away if you have any symptoms of having too much serotonin. These symptoms include a fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion.
Effect on driving and concentration
- Risk factors: Taking with alcohol or illicit substances | Taking other medications that cause drowsiness | People over 65 | Taking metaxalone with a full meal
Taking metaxalone can make you feel sleepy. The medication can also affect your concentration and focus. These side effects are more likely to happen or be more intense if you're over 65 or if you take metaxalone with a full meal.
Don't drink alcohol while you're taking metaxalone to lessen the risk for intense side effects. Avoid activities that require you to be alert, like driving or operating machinery, until you know how the medication affects you.
Caution use in people with liver or kidney problems
- Risk factors: History of liver problems | History of kidney problems
Metaxalone might not be the safest choice for people who have liver or kidney problems. The medication is processed in the body by the liver and kidneys. Metaxalone can buildup in the body if either of these organs isn't working properly. This can raise the risk for dangerous side effects, like serotonin syndrome.
