My partner has been prescribed Gabapentin for back pain. Since moving to a higher dose, he has had trouble maintaining an erection. The prescribing information for Gabapentin says that this is a possible side effect, but I'd like to know more about it so I can discuss it with my partner.
Impotence has been described as a possible side effect, so your partner should let the prescribing doctor know this has occured and see if it can be addressed by switching to another medication or moving back to a lower dose. After doing some research, the good news is that this appears to be a problem that only occurs while taking the drug. Those who have stopped it report a return to normal sexual function.

After reading some of the comments on this page, I'm inclined to believe that Gabapentin can also cause severe spelling loss...
My husband just started taking this medication and our information did not mention erectile problems at all. My husband is still able to get an erection but it is not a full erection and goes limp quickly and he has a very hard time achieving orgasim. He was perscribed this for back pain as well.
I'm submitting an answer to add some more body to the statement that Gabapentin causes erectile problems.
I've been taking 2400mg of Gabapentin daily for 2 years and will probably continue to do so for the rest of my life. I take it to reduce the effects of Nystagmus (google if you're curious!). It works wonderfully and has changed my life for the better.... mostly.
I am able to hold an erection but it can be difficult and never very hard. Certainly hard enough for good sex but not as hard as I'd like. Generally it takes a lot of effort to climax and can get a bit, errrmm, rough? . I dunno, but it's can be very frustrating for me. Gladly it doesn't worry my wife.
Sensation is greatly reduced by the medication which is why it's tough to climax. In my experience the side effects only last as long as the benefit of the meds. I take it 3 times daily and it works for about 5hrs. I definitely get more enjoyment from sex first thing in the morning as it's 10hrs since my last dose. If I want better sex I miss a dose then take it after - which is easier with my condition than it would be for others - however, trying to predict when my wife will be up for it is probably the biggest issue lol.
Unfortunately there is no alternative medication for my condition, in fact this isn't even signed off as an official treatment as it's still under long term trials.
I'm gonna speak to my GP about trying viagra (pretty embarrassing for a 32yr old) but having read a comment above I'm not confident that it's gonna help.
Anyway, keep at it guys. Get heavy handed if you have too, or if you can delay a dose that might help. I find that thinking and worrying about it makes things worse, so try to clear your minds and go with the flow <!--[endif]-->
Indeed. Neurontin (Gabapentin) DEFINITELY causes erectile dysfunction. I am taking it for nerve pain from cervical spinal stenosis. It makes gaining/maintaining erection impossible. Even with Cialis or Viagra, achieving orgasm is also (nearly) impossible. I am angry that this Blaring Side Effect has been down-played so much. I can't wait to have my surgery to free my spinal cord and be rid of the nerve pain. The pain is so bad, I "have to" keep taking it for now. Unfortunately, it's already to late to save my relationship. My girlfriend believed all the crap on the internet that said it was minor or uncommon & concluded that it was "her" or that I must be cheating, (or both). She is a little flaky but, I really loved her & miss her alot. Not so much looking forward to going thru surgery alone either.
Gabapentin could be the cause of his problem, but is he on any narcotic pain relievers (like vicodin[hydrocodone], codeine, percocet, norco, etc)?
If so, the narcotic is probably the culprit, because narcotics (opiates/opiods) have a really strong tendency to make it difficult to achieve and maintain erections. Gabapentin on the other hand can cause erectile difficulties too, but it's less common especially in lower doses.
I just started taking Gabapentin and am having problems getting and maintaining and erection. I have been reading a lot about this and have noticed it to be a common problem among men. I do not take narcotics for my back pain, and did not have trouble before I started the therapy. I am on a low dose, and am having other side effects as well. To say its less common may be false, unless most of the test subjects are female.
