Paraphilias, also known as sexual interest disorders, often go unaddressed due to the reluctance of patients in seeking care. Many individuals with these conditions avoid medical attention because of concerns about stigma, legal consequences, embarrassment, and personal shame. Management of paraphilic disorders involves a range of therapeutic approaches, including behavioral and psychodynamic interventions, pharmacologic treatments, and, in some cases, surgical options. Although medications can help suppress unwanted sexual behaviors, their use is associated with potential adverse effects. Understanding the nuances of these treatment modalities is essential for providing effective, comprehensive, and compassionate care.

Testosterone is the hormone most commonly suppressed by pharmacotherapy in the treatment of paraphilic disorders. Many treatments including gonadotropin-releasing hormone agonists (such as leuprolide and triptorelin) and antiandrogens (such as medroxyprogesterone acetate and cyproterone acetate) work by significantly reducing testosterone levels. This suppression leads to decreased sexual fantasies and deviant behaviors but can also cause adverse effects like weight gain, muscle tension, and gynecomastia. Regular monitoring of testosterone, along with follicle-stimulating hormone and luteinizing hormone, is essential to assess treatment effectiveness.
Although cortisol is relevant in stress response and some psychiatric conditions, it is not the primary hormone affected by pharmacotherapy for paraphilic disorders. Estrogen, a primary female sex hormone, is not the focus of suppression in these cases. Progesterone, though sometimes used in antiandrogen therapy, is not the main hormone suppressed but rather might be administered to counteract testosterone’s effects.

A systematic review found that the recommended treatment for long-term suppression of paraphilic urges was antiandrogens combined with psychotherapy. Combining pharmacotherapy with psychotherapy enhanced self-efficacy and impulse control while reducing recidivism rates. Psychotherapy might uncover and address the underlying causes of this disorder. However, antiandrogens could have adverse effects and vary in responses, and patients might need close monitoring and appropriate supplementation.
Although psychotherapy alone, particularly cognitive behavioral therapy, can help manage paraphilic disorders, it was generally less effective than when combined with antiandrogen therapy. Although some anticonvulsants, like topiramate, have been explored for impulse control disorders, they lacked strong evidence in the treatment of paraphilic disorders. Antidepressants, like selective serotonin reuptake inhibitors, can be beneficial in reducing obsessive sexual thoughts and addressing comorbid depression or anxiety, but they were not as effective as antiandrogens for long-term suppression of paraphilic urges.

Relevant assessments for patients with paraphilic disorders undergoing treatments include bone density, hormone levels, blood pressure, and glucose levels. Many of these treatments cause a meaningful reduction in testosterone levels; however, this can lead to bone demineralization and osteoporosis. In turn, this might lead to higher risks for increased bone fragility and fractures. Therefore, bone density assessments are important to track and mitigate these risks, and calcium and vitamin D supplementation are often recommended for patients undergoing treatment.
Although electrocardiograms are useful for detecting heart-related adverse effects of some psychotropic medications, they are not the primary concern for patients on antiandrogen therapy. Although some medications used in paraphilic disorder treatment can affect liver function, liver enzyme monitoring is not as crucial as bone density measurement. White blood cell count is not a primary concern for patients on antiandrogens or gonadotropin-releasing hormone analogs.

The recommended follow-up period for assessing treatment response in patients with paraphilic disorders is 3 months. This timeframe allows for a thorough evaluation of symptom stability, treatment efficacy, and potential long-term adverse effects. The period of 4-8 weeks is too short to reliably assess symptom consistency and treatment efficacy, especially for medications that require longer durations to reach therapeutic levels and produce stable effects. Some patients might require more long-term supportive monitoring.

Selective serotonin reuptake inhibitors are recommended for patients with paraphilic disorders who have comorbid OCD and do not respond to cognitive behavioral therapy. The World Federation of Societies of Biological Psychiatry supports their use due to their dual ability to reduce compulsive behaviors and dampen sexual drive. Fluoxetine and sertraline have shown effectiveness in treating various paraphilic disorders, such as pedophilia, exhibitionism, and voyeurism. These medications might also address some of the underlying depression that leads to paraphilic disorders.
Although serotonin and norepinephrine reuptake inhibitors affect serotonin levels, they primarily target norepinephrine, which does not have a well-established role in treating paraphilic disorders or reducing compulsive sexual behaviors. Anticonvulsants are typically used for mood stabilization and seizure disorders rather than for compulsive sexual behaviors or paraphilias. Electroconvulsive therapy is generally reserved for severe mood disorders, such as treatment-resistant depression. It is not a recognized treatment for paraphilic disorders or OCD.
