Common Drug Q&A » Pain » Robaxin


A: Robaxin is a muscle relaxant and works on the nervous system. If this is not working then return to your Doctor and explain that it is not working. I do not advise you walk in and demand a different drug, just explain it is not working. As for ‘lower back pain’ drugs do not ‘target’ any particular areas, so even if you had pain in your finger or toe, you would probably still be prescribed the same drug. Best of Luck

Q: How Long does Methocarbamol (Robaxin) stay in your urine?
I have an upcoming drug test and took a Robaxin and need to know how long it stays in your urine

A: The elimination half-life of methacarbamol is 1 to 2 hours. It takes five and a half (5.5) half-lives for the drug to be out of your system.

Therefore the drug will be in your system for about 11 hours (5.5 x 2 hours).

Q: Is it safe to take robaxin while nursing?
Ok, I went to the doctor today for my severe headaches and he is perscribing me robaxin. I told him that I was nursing and he said it wouldn’t affect anything, however; researching on the internet is says to not take while nursing. Should I listen to this random doctor?

A: if you need my advice donot take it there is no enough papers about safety and it is excreted in milk so would harm your baby

Q: What is in Robaxin and how much is safe to take?
I know that it is methocarbamol, but what exactly is that and what does it contain?

A: Methocarbamol is a muscle relaxer. take 1 every 3-4 hours or as directed by your physician

Q: What does the word Robaxin mean and what is it used for?
I know that it is a kind of medicine. Layout its uses and effects.

A: This medication relaxes muscles. It is used along with rest and physical therapy to decrease muscle pain and spasms associated with strains, sprains or other muscle injuries.

This medication is taken by mouth usually 3 or 4 times a day, or as directed by your doctor. It may be taken with food or immediately after meals to prevent stomach upset.

Side effects include: Stomach upset, nausea, flushing, constipation, headache, blurred vision, lightheadedness, dizziness or drowsiness.

Q: Is it safe to mix Tylenol and Robaxin medicines?
I am a 52 years old non-drinking male. I took Robaxin as directed last night and Tylenol #1 as directed last night. I had nausea all day today, although it appears to be resolving tonight. I did not feel like eating food all day until just about now. Do these two drugs compete for liver metabolic pathways?

A: Robaxin is a muscle relaxer, right? I have taken it before and I actually took it with Percocet, (that my doctor prescribed for me)- which has the same properties as tylenol, so if you were feeling sick, it may just be that your body is not used Robaxin, but you can mix the two. I hope you feel better!

Q: my tongue is numb after taking robaxin and darvocet?
Any thought of why? Im also very dizzy. But my tongue is numb. I took the genaric brand of both for my back.

A: Stop taking these meds………you are allergic to them. Call your Dr. immediately and tell them what is going on with you. I work in Pharmacy and I know what I am talking about. Please, do not take anymore of these meds. Good luck!!!

Q: I was prescribed robaxin but it only works for an hour, what should i do?
My doctor prescribed me robaxin for my back pain due to scoliosis and it seems to only work for about an hour. It says on the bottle take one every 4-6 hours so im scared to take another because i dont want to OD. Should i call and complain? should i ask for a stronger muscle relaxant? They have been on my a** about doing physical therapy but i have a 6 month old and i just dont have the time. What should i do?

A: Yes, you need to call the office and let them know that the medicine is only helping for a very short time and you aren’t sure what to do next.

As for the issue of physical therapy, there’s a lady that goes to PT who has a baby and when she comes and is able she just brings the baby with her.

Also, many PT places may be able to offer you extended hours. Another option is to go just once for consultation and ask for a home exercise program.

If you have other questions about physical therapy please feel free to e-mail me off site any time. Please put in the subject line: “Questions about Physical Therapy” so that I will know what htis is in regards to.

Q: The Doc prescribed me Robaxin for back pain it dont work??
It doesnt help the pain plus upsets my stomache and gives me a headache. I wonder what medicine should I try or ask for? The pain is near the middle of my shoulders, and I read Robaxin is for lower back pain,,,any advice? Thanks!

A: Stop the medication if it is upsetting your stomach, especially since it’s not helping the pain anyway there is no reason to do harm to your gut. Robaxin can be very hard on your stomach and some people can not tolerate it. My best advise is to seek out a good chiropractor. I was in a bad car accident when I was 19 and suffered for about 3 months with muscle relaxers and pain medications that didn’t work and then one of my co-workers referred me to her chiropractor. When I went into the office the first time I couldn’t stand up straight, couldn’t turn my head fully right or left and I had been having a headache since the accident that never would go away, I could barely walk, it hurt to sit for any length of time, and I couldn’t take a deep breath. After just one treatment I left the office without a headache, walking straight, and I was able to turn my head left and right without pain. I wasn’t cured, but I was on my way. After about 6 months of treatment I was good to go.

Q: Does anyone know if the muscle relaxer Robaxin is similar to Soma?
Does it have the same make you tired drowsy kind of effects of Soma? I need to know if I should take this while at work or if it would help me sleep at night.
So its not going to give the same buzzed feeling like the Vicodin I am on, correct? I was taking skelaxin before and that didnt make me tired. I just remember somas mad eme tired and are also muscle relaxants and with my injuries its hard for me to go to sleep so I was hoping this new perscription would somhow help with that.

A: I cant use meds so here is a different option

Much pain is from muscles below is an example of what may help (based on headaches).
Begin with a couple swigs of molasses or a couple of bananas (natural muscle relaxers) daily – magnesium (which regulates many things in the body) and potassium (a needed building block for muscles).
Drink at least 1/2 gallons of water per day. Running a body low on water is like running a car low on oil is the analogy the head of neurology at UCDavis told my husband about 10 years ago.

Now to the cause – muscles – your back, neck shoulders and head have tender spots. They are knots in the fibers of the muscles called trigger points. It makes the muscles tight which makes them press on nerves and other things causing the pain.

The cure – start with a professional massage, (if this does not do it you probably need a chiropractor as well) you will also want to go back over any place you can get to 6-12 times per session up to 6 times per day rubbing (or lightly scratching on your head) every where that is tender until the knots go away. The place where the skull connects to the spine press up under the edge of the skull (to get to those muscles).

For more information read The Trigger Point Therapy Workbook by Davies. It teaches what to do and where the pain comes from.

Q: Is it safe to take Robaxin, long after it has expired. Internet says throw away, I’m not sure if they say that
about all medicines or just Robaxin because it can be dangerours.

A: Being a Pharmacist I highly endorse the answers above that suggest you to throw away an expired medicine soon as its date is over. Most prescription medicines lose potency after their expiration dates, many can become toxic and even deadly.

Using “long after it has expired” is simply out of question.


Please look back into your medicine chest and make sure you throw away all expired prescriptions.

Best wishes!

Q: What are your experiences with methocarbamol (Robaxin)?
I was prescribed this by a neurologist after a whiplash/concussion 2 1/2 months ago. I actually went to the neurologist due to concerns over my constant headaches and some issues with cognitive changes. This drug makes my already horrible headaches 300% worse. It seems to make me more foggy mentaly. Best of all it seems to have made my shoulders hurt even MORE.

A: I thought it was just me. I also had terrible headaches when I was taking Robaxin. I think it is one of the side effects. Ask your doctor to prescribe you another type of muscle relaxer I switched to Flexeril but there are a lot of others out there. You have to find the one that works for you.

Q: What ‘high ‘ effects will I have if I take a methocarbmol pill (Robaxin)?
My friend gave me these two pills she told me they were vicodin but i looked thtough it and they’re Robaxin, if I take them will i feel any sort of high?

A: It’s used to treat skeletal muscle pain. You won’t get high from it.

Here’s a list of the wonderful things that might just happen to you: Amnesia, confusion, diplopia, dizziness or lightheadedness, drowsiness, insomnia, mild muscular incoordination, nystagmus, sedation, seizures (including grand mal) and vertigo.

Q: what will robaxin and chloraxazone show up as in a six panel UA if anything?

A: Depends on how long you’ve been taking them, but they usually don’t last in your system longer than 3 days.
