Dear user, Thank you for writing to HCM. I understand your concern for premature ejaculations. Gabapin medicine commonly causes Imbalance, Dizziness, sleepiness and fatigue. It is very less likely to cause changes in libido, ejaculation disorders, and difficulty in orgasm. I suggest you to quit it for at least 10 days and see whether premature ejaculation improves. If it is so, it is likely that it is due to Gabapin. You may consult your treating doctor and discuss this with him. There are different treatment methods for premature ejaculation. Some are as follows: 1. Stop-start technique of behavior therapy. 2. Female on top with active role. 3. Double condom 5. Pelvic muscle strengthening exercise. (As if try to hold urine intermittently during voiding) 6. Penile squeeze technique applied at the point of ejaculatory inevitability. 7. Applying a local anesthetic ointment to glans penis prior to penetration. Medicines like Fluoxetine 20 mg day or Paroxetine CR 25 mg per day. (To be taken under medical supervision only) Wish you good health. Regards.
