Anorgasmia during pregabalin add-on therapy for partial seizures

Area of Science:

• Neurology
• Pharmacology
• Sexual Medicine

Background:

• Anorgasmia, the inability to achieve orgasm, is often linked to psychological factors.
• However, certain medications, like serotoninergic drugs, are known causes of situational anorgasmia.
• Pregabalin is an antiepileptic drug used for epilepsy and neuropathic pain.

Observation:

• Three men with epilepsy were treated with pregabalin as an add-on therapy.
• These patients subsequently experienced severe anorgasmia.
• The anorgasmia was directly linked to the initiation of pregabalin treatment.

Findings:

• Pregabalin use was associated with the onset of severe anorgasmia in all three male patients.
• This suggests a potential causal link between pregabalin and drug-induced anorgasmia.
• The severity of the anorgasmia indicates a significant adverse effect.

Implications:

• Clinicians should be aware of the potential for pregabalin to cause anorgasmia in male patients.
• Further research is needed to understand the prevalence and mechanisms of this side effect.
• This finding may prompt a review of prescribing guidelines for pregabalin, particularly in patients with a history of sexual dysfunction.
