I'm posting for anyone that is searching and ends up here. Neurontin can absolutely cause weight gain. This is especially true with females. I gained 20lbs in 3 weeks and a total of 25 at 6week point. The doctor kept upping and upping the dose because it was not helping the pain. Nothing in my habits changed. If I'd known, I probably would have still tried it to help chronic pain at the time. The Dr discontinued it after my substantial weight increase. What he did not tell me was that it was mostly fluid I had gained. In my case anyway, that's what it felt like too. Much of it concentrated in the midsection... made me suddenly have moon face too. It took me a year to get it off. My mother was prescribed the drug several years later. I warned her but she tried it anyway. She gained too, but her doctor told her the weight gain was generally fluid. He explained they could let mother nature take it's course eliminating the fluid over 6mons to 1yr or use a diuretic very short term to expedite the process. She used the diuretic and lost the fluid weight quicker. I'm not saying this drug cannot cause another person to gain body fat. I'm simply stating my experience.
