What is the overdose amount of Flexeril in milligrams?

8 Answers

Official Answer by Drugs.com 9 Aug 2009

For most people, the recommended dose of Flexeril is 5 mg three times a day. Based on individual response, the dose may be increased to 10 mg three times a day. Use of Flexeril for periods longer than two or three weeks is not recommended.

Anything above the recommended dose is considered an overdose.

An overdose of Flexeril can be fatal. Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Symptoms of overdose may include severe drowsiness, vomiting, fast heartbeats, tremors, agitation, or hallucinations.

I have a bottle of a 45 10mg Flexeril I say I would take about 15 of them over about 12 hours and I really have no effects at all

I will not tell you that information, but I WILL tell you the side-effects of overdose of Flexeril.

"Overdose symptoms may include drowsiness, fast heartbeat, tremors or shaking, slurred speech, confusion, nausea, vomiting, hallucinations (seeing things), chest pain, or seizure (convulsions)."

(According to, Drugs.com)

Doesn't sound like a very good experience...

My girlfriend took about 20 flexerils before i could break down the door and get pills away from her... she was treated with in 20 min of injestion and was in hosp for 3 days before being released. She now seems like she had a mild stroke because she has severe short term memory loss and gets easily confused. She gets lost going to work (even with a GPS). She turns her car where there are no entrances to parking lots and keeps bouncing off curbs.. Her OD was about a week ago. Will these symptoms fade or has she done some permanent damage to her brain from slowing down the blood flow??

I came here for the same reason and feel worse than I did before.

If a person is chronically ill, we should get to ask for a shot instead of having to hide my feelings, only talking under an alias . . . you'd think we're talking about bank robbery rather than trying to deal with extreme measures of pain everyday. Oh well, I guess I'll take another 1000 mg of motrin and see if I can get through cleaning my apartment.

I got 260mg waiting for me. Probably will only be enough to make me really sick, but not enough to finally end the suffering. Jumping off a building or a bullet to the head seems like a more sure way to get out. These pills are just a cry for help. And I'm tired of crying. And tired of asking for help that never comes.

I took 90- 10mg flexorils, 90- 50mg trazadons, and 30- 30 mg restorils. Sadly, I did not die.

That is just very sad.
Finding solutions to end life is difficult at best. Hopefully you are dealing better

I was on Flexeril for years when I found myself feeling as if I wasn't getting any relief.so I then found myself taking more than my prescription called for which was 1-10 mg 3/ daily, instead I was taking 2-3 at a time and I called myself going to the doctor and telling her what I was doing.m
y doctor said ... "Do you want me to cut u off ? U can go to sleep and never wake up.ur meds are a muscle relaxer and ur gonna relax ur self to a point of no return ." I stopped them all together!

I took 600mg of Flexeril not long ago. Laid down and went to sleep. Apparently woke up and stumbled around the house before finally laying down on the floor. I woke up in the hospital confused. I couldn’t tell anyone the date, where I was, or what I took. I forgot questions as soon as I started to answer them and drew blanks in mid topic for 3 days. I think more might be messed up then that. I am glad I’m still alive. I’m also scared something worse is there.

I don't have the answer, only this experience:
My husband has Stg 4 lung cancer and had terrible back spasms last night. He said he took 1 flexeril, another an hour later then sometime later, another 4, for a total of 6. Today he is very weary, slurring, possibly hallucinating (he was seeing things, like a cat, that I could not see in the papers and junk on the table.) Very scary to me, I'm his only caregiver. He went back to bed to "sleep it off".

Technically, anything more than your Rx. So with the ones I have, that would be more than 1x 10mg tab TID. This is a hard question to answer because of individual variations. My ex wife could take 3 at a time and go to work at a job that was both physically and mentally demanding, without impairment. I take one, and it kind of knocks me on my butt. However, my other medications intensify the effects.
