Certain medications can bring on libido loss as a side effect. “Desiring and engaging in sexual activity requires a range of neurological structures to work properly,” said Gabriella I. Farkas, M.D., Ph.D., a psychiatrist in the greater New York City area, noting in particular the cerebral cortex, limbic system, pituitary gland, medulla oblongata, cerebellum and peripheral nervous system. “If even one of these is damaged or underperforming, libido may be substantially compromised.”
In addition to disorders like depression, anxiety and Parkinson’s disease, medications known to interfere with these functions and sex drive include SSRIs like Prozac and Zoloft, Anafranil, which treats OCD, and antipsychotics. Antihistamines, opioids and some birth-control pills can also lower libido.
