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.
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.
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".
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 took 2 10mg flexeril and 2 1mg Klonopin and nothing has happen so far.
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 90- 10mg flexorils, 90- 50mg trazadons, and 30- 30 mg restorils. Sadly, I did not die.
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)."
