Hello Shanon,
To the best of my knowledge, the max dose of gabapentin is 3600mg per day. I currently take 2700mg myself on a daily basis. I take it for fibro and neuropathic pain. I hope this helps you.
In peace,

Hi, shanon, as an ex-downhill mtber, I have severe nerve damage in my forearms and hands, have difficulty even holding a cuppa now, and I'm only 40. I'm on 2700mg of gabapentin, I'm thinking of asking my doctor to look at other options, as I've got to this amount over the period of a year and a half, and Myself and my wife are noticing a 'big' decline in my functions.

I've been asked to take 1600mg twice daily, but it started to not work. I changed it to 2400 twice daily for around two months or so but it still wasn't working as well. I eventually changed it of course myself not by doctor three times daily and it works most of the time and I've been using it like that for a few weeks like this but now it's not lasting through the night and my nerves are misfiring so fast that it feels as if it's vibrating and itches extremely. I don't know what to do. I just want to cut off my hands cause it's so painful I can't stand it anymore. Please if anyone has answers.

It is 3600mg. Usually it is administered 900mg 4x per day at that dose. I was at that dosage for a couple years. When needed, lower dosages are slowly raised by a doctor after side effects and benefits are evaluated at lower dosages. There is a lot of information out there that indicates its effectiveness wears out for some people and an increase may be needed. However, once you are at 3600mg, you have no place to go. Personally, I would recommend trying to not go past 2700mg, so you have the mental encouragement that it can be raised if things get worse. People at these pain levels need psychological strengths as well. At 3600mg, you might be able to find a doctor that will prescribe Lyrica in addition to get to a higher dose of gaba receptors. I would suggest researching the FDA guidelines first on that issue. Everyone reacts differently to meds.

yearsofit: I read your answer to the woman asking about gabapentin.

Your story is one that is quite emotional to this reader.
I just wanted to say good luck in training your brain and stopping the
ringing in your ears.

I wish you good luck and my prayers are going out to you.

Hang in there. :)


yearsofit 10 Nov 2014

Thanks for your concern and prayers. It's been 1 1/2 years since being on here, so another long recap. Doing a lot better. About a year after stopping gaba, weight started dropping back to normal without trying. Ear ringing got better and still haven't had another pneumonia. Pneumonia almost got me several times during my decade from hell. Even though pneumonia is listed as a rare side effect of gaba, being bedridden and not being able to breathe deeply without pain were probably the bigger culprits. Vision has stabilized, so I am not using 3 different glasses.

The maximum dosage is 3600 mg. I have been on 2700 mg & I take 900 mg 3x day & have been on this dosage for about 10 yrs. Once I felt like I needed more my Dr. decided to put me on Lyrica with the Gabapentin. Between the two medications they worked really great. So speak to your Dr. & see what would be best for you.

Did you have weight gain with these? I'm new to Gabapentin but also going thru the change and not sure if it's from one or the other but I'm def more hungry than before. And man oh man when it wears off... whew I didn't realize how bad my pain was until I got that relief from Gabapentin! I was really hurting. FM makes me more likely to just accept and try and ignore all pain. It's so odd how tramadol worked for my whole body EXCEPT from ankles down lol.

A Real Doc 29 Sep 2017

Listen folks, you need to be aware of one important thing when it comes to medications such as Gabapentin:It should never be stopped abruptly, even if it hasn`t helped you , especially for those of you who were on max or near max doses.It should be tapered down slowly over 2 weeks ,otherwise there is a real risk of causing a seizure!

Scteve 30 Jul 2013

In 2008 a Neurological Surgeon put me on a dose of 6400mg a day taken 4 x 1600mg every 6hrs for pain after an amputation... It seriously messed me up in the head after being on it for >6mo... Does this mean the UW Hospital Surgeon overdosed me???

jjaymes 11 Apr 2016

You'd be worse off without it. It speeds me up @ 1500mg twice daily. Keeps me awake. Helps with leg monsters and sciatic pain. Paraplegic leg pain.

Callie Z 16 Jun 2016

I know this is old, but yes, you were overdosed on gabapentin. The maximum dose is 3600 mg. daily. Also, there is no indication that taking more than 1800 mg. daily (usually given in 3 daily doses of 600 mg.) gives any better results than taking 1800 mg. daily. I would suggest that everyone go to an official website to get accurate information on any medication you are prescribed to be well informed.

GilHodges014 26 Aug 2013

I am taking 5,200 per day for a nerve problem, causing severe pain, in my right leg and have crazy effects from it at times including a complete loss of my muscles. That includes dropping things that I am holding and even having my knees go out on me (though that has only happened twice). If the pain in my leg was not so bad I would cut back but the medication is the only relief that I can find.

TammyFink 25 Jan 2015

So this is why my left knee goes out on me, which has occurred while I was out and this was sop embarrassing, but what can you do about it. I have Sciatica which came from my piriformis being inflamed, which is located in my butt and with it being inflamed for a year and half it's now caused permanent damages, which has changed my life.

TammyFink 25 Jan 2015

And I'm prescribed 600MG three times a day.

talkinaboutmeds 28 Jun 2014

3600 seems to be the magic number. I've been on gabapentin only a few weeks but already I've jumped from 900mg a day to 2400mg. I take it 600mg in four doses, breakfast, early afternoon, late evening, and bedtime. It really help with the sciatic leg pain and back pain. I have a herniated disk and I am waiting to have surgery as soon as they can schedule me. I think gabapentin is a great pain reliever, although it does make me very drowsy and clumsy. I would say don't drive while you're on this med.

Lucy1536 12 Oct 2015

Thank you so much. I'm going thru the same problem

tolleyrands 15 Oct 2015

I've been on gabapentin over a year now and it has been a blessing. I take 800mg at wake up, lunch, evening and bedtime. It really helped with my sciatic leg pain and back pain. I have a herniated disk and myofascial... I think gabapentin is best pain reliever even better than all the narcotics I was on for 13 years. I think more doctors ought to offer this at a higher dose for their pain managed patients. Just my thought.

inextremepain 12 Aug 2014

I take five(5) doses (6000mg) of 1200mg spread out through the day and evening. My first dose starts when I wake up and the last dose is before going to sleep. I have an acute burning throughout my body even though I'm taking this crazy daily dose. My doctor says its nerve damage. Double vision is something I've experienced since I started this dose. Is there anything else that anyone knows of that I can take which will reduce the burning feeling and do away with my double vision? Any help is appreciated.

Chelsea Caudle 19 Sep 2015

The blurred and double vision goes away with time eye drops saline drops help and from the really bad burning pain a muscle relaxer helps my doctor put me on one called Zanaflex that really helps and Percocet with tramadol. Also smoking marijuana when the pain and burning sensation gets really bad helps I use to judge people who used drip until I started having chronic back pain.I have a pitched sciatic nerve bulging disk severe arthritis so does my husband three small children he takes 1600mg of gabapitin a day I take 900 but I am asking the doctor to increase my does at night


I have been taking 14,000 mg for about 2 weeks. 24 of the 600mg pills. I am freaking out that I am about to run out. I started with a few and went up to this.

I have cervical spinal stenosis with myelopathy in my neck, spondylosis and degenerated discs with 3 fusions completed in less than 2 years. Basically my whole neck is crashing down and pinching my spinal cord in various places. I didn’t find Lyrica to be helpful but gabapentin was a miracle drug for me. I am also on various other drugs for pain, fentanyl patch, Effexor (anti-depressant for nerve pain), muscle relaxer cylobenzaphrine (very effective too) and Celebrex for arthritis. It was trial and error until finding the right “cocktail” mix that worked. Higher dose of gabapentin helped me the most, over 1800, until I was on 2,400. I had few side effects. The dropping items while trying to grab them on occasion and being forgetful, out weighted the pain relief I received.

Amseaton44 21 Dec 2014

My neurologist has prescribed me @ only 900mg a day (1 300mg 3x a day)... This is a medication neuropathy and other things, I'm guessing. So far from what I've read, I am on the smallest does here. And I have a question also: does THIS particular med help with jitters (or ticks)? Or make it worse? I'm real jittery and have this annoying "ticks" (involuntary spasm movements) and it drives me crazy. You guys have mentioned sides effects if "forgetful" & "dropping" things, and I have both of those but idk if it's from just this med or a combo of this and others that I take! I take a crapload of things from diff diagnosis!

dmp2469 7 Mar 2017

My Dr. Had me on 300 a day... Well I talked to someone, who took 1,800... So, I'm going to increase to 900 a day?? So no.. I'm the

Heatherbarbie32 1 Sep 2017

Every since i started ive had continuous ticks & muscle spasams

qrleonard 17 Mar 2015

I have trigeminal neuralgia, nerve damage in my face and I haven't found a dose of gabapentin that has been effective... currently taking 900mg tid but no real relief... I'm in so much pain when I have a flare up... maybe another med is needed??

geturnquist 23 Mar 2015

I feel you pain as I have Glossopharygeal Neurologia. I'm maxed out on Carbamenzaprine and at 3000 of Gabapentin. My doctor told me was time to call the Mayo Clinic. I'm surprised they haven't sent you there. Good luck as I've heard these pains are the worst one can experience.

CR123 11 May 2015

I was upped to 1200 for TN and gradually reduced to 900. I am now at 600 but have to be very careful about my triggers, however, by and large it works great..but it took a few weeks.

Tuckwolf 24 Apr 2015

The information I've seen indicates a maximum daily dosage of 3600 mg but I was prescribed two 600 mg tablets four time daily and I've taking it for 10 years with no problems. However I rarely take it except at night and for occasional anxiety which is common for people with my disease. I was diagnosed with Myotonic Muscular Dystrophy 14 years ago.

CR123 11 May 2015

I am so glad you posted that you have been on Gaba for 10 years , I am going on 4 years this fall and was worried that it might be too long. I am on a much lower dosage for TN and it is great to see that you have had not ill effects... nor I have I to this point.

Deirdre Singer 1 Feb 2016

I was prescribed 300mg tds and I asked if I could go up to 400mgs as nothing was working .Crazy or what. I've been making the mistake of taking 1200tds but the good thing is it actually has got rid of my pain which I've had for over 16 years feels like heaven ,I've been taking 3600 daily .Is that too high a dose?? Please advise.Dont want to go down a dose now as pain will come back.

2litters 14 May 2015

600mg 5times a day

Watchandpray 17 Oct 2015

How does the 600 mg 5 x a day work for you? When do you take them at what times of the day? I am taking 600 mg 3x addy if need more relief.

Laurieroz 8 Jan 2016

I take it 6 times a day; every 2.5 hours, starting at 10:00 am.

cody pate 28 Jun 2015

What is the effect if 36000 of ran-gabapentin is taken at one time

Migs63 17 Sep 2015

I think you would die taking that amount :) I'm guessing you meant 3600mg..I don't no what the effect would be..I take 3600 a day but I think it'd probably be dangerous taking them all in one go because of the sedation effect.

iamnobody3 9 Jan 2017

well actually, because of the way gabapentin is absorbed, its quite hard to overdose on it. 3.6g of gaba a day will give some people lots of anxiety relief, for me it seems better for anxiety then any of the benzos i've tried. also a couple hours after i start taking staggered dosages, i just start feeling and hearing my neck and back spontaenously popping, and the relief from the popping feels great. i'm only on 1.8g a day, but my doctor said i can double up when needed, so i usually use them on about 2/3rds of the days on average, and a couple days off will let the anxiety

lizkates 23 Jul 2015

What is the maximum amount of gabapenten allow in 1 day

tolleyrands 15 Oct 2015

I'm on 800mg 4x a day. works great for me

Inactive 15 Oct 2015

Gabapentin is a great nerve pain reliever. Exercise is better. The side effects of Gabapentin are more severe than I thought. When I was taking opiods I thought they were making me lose my balance. Nope, It was the Neurontin. Double vision and drowsiness were also side effects that weren't noticeable over the opiods. Exercise works better than Gabapentin and if you are able to exercise you can wean off the drugs.

Hi all, I rarely rely to comments nor take any drugs at all. But I can tell you that my sciatica starting from my quad down is sooo bad I nearly teared up. And I have a high tolerance for pain. I can only speak from t he short term, which is 60 days or less. And I would say that I currently need 2400 mg per 8 hours, totaling far more that you are recommending. But I will also say that I am OK with it- and in fact in severe pain without it. We all know that I cannot continue that in the long term, but so grateful to have it and able to barley walk even then. I recommend talking such a high does only during the first 8 PT visits to get through the shocking pain. My two cents

I just came upon this commentary. I have a family member post back surgery with him peripheral nerve injury and on
Gabapentin 3x a day 900 mg doses. With PT intensity pain got a lot worse. Saw above someone had added Lyrica and wondered if that might help. For severe pain jolting episodes I find moist hot compresses work.
Wondering if Tens therapy in other muscles areas may distract overactive hyperalgesia in current affected areas. Also family member on B12 and Magnesium but want to see if essential oil applications work you would work ( those designed for neuropathy).
