Neurontin Sexual Side Effects

Of the adverse effects seen with Neurontin, sexual side effects have been reported in between 1 in 100 and 1 in 1,000 people taking the drug. These side effects include problems with ejaculation or orgasm, changes in sex drive, and impotence. If, while taking Neurontin, sexual side effects occur, your healthcare provider may adjust your Neurontin dosage, recommend treatment, or prescribe a different medicine to treat your condition.

 

Neurontin Sexual Side Effects: An Overview

Neurontin® (gabapentin), like many medications, is known to cause certain sexual side effects. Possible Neurontin sexual side effects may include:
 

Neurontin and Sex Drive

Neurontin may cause changes in sex drive (also known as libido). Decreased sex drive (or even a complete loss of sex drive) was reported in between 1 in 100 and 1 in 1,000 people taking Neurontin. An increased sex drive is also possible, but is less common, occurring in less than 1 in 1,000 people taking the drug.
 

Neurontin and Problems With Ejaculation

Neurontin is also known to cause ejaculatory problems in men. In clinical studies where Neurontin side effects were documented, ejaculation problems occurred in up to between 1 in 100 and 1 in 1,000 men. These problems could include delayed ejaculation, inability to ejaculate, or other ejaculation problems.
 

Neurontin and Problems With Orgasm

Neurontin may also cause orgasm problems, particularly an inability to achieve orgasm (in both men and women). In clinical studies where side effects of the drug were documented, orgasm problems occurred between 1 in 100 and 1 and 1,000 people taking Neurontin.
