I take gabapentin 200 mg daily before bedtime, now I'm thinking of dropping the gabapentin since it may contribute to swelling in my left leg, a problem that has been that way for many months now, moreso after I got arthroscopic surgery for meniscus repair left knee in April 2025. But I'm 77 years old now and ED is a real problem for me, as well as primarily total loss of libido and of course along with the major ED. I never connected gabapentin use to ED however. Maybe it is coincidental for you, but you need to consider viagra and/or cialis and see if there is help there. You may be of the age that ED is becoming more commonplace.
