Pregabalin, used for anxiety, can cause sexual side effects like disinhibition and increased libido. These effects may be managed by reducing the pregabalin dose.
Area of Science:
- Neuroscience
- Psychiatry
- Pharmacology
Background:
- Pregabalin, a gamma-aminobutyric acid (GABA) analogue, is commonly prescribed for anxiety and neuropathic pain.
- Sexual side effects are infrequently reported with pregabalin treatment.
Observation:
- A 27-year-old male with recurrent depressive disorder experienced acute sexual disinhibition and increased libido.
- These adverse sexual effects emerged during pregabalin therapy for anxiety symptoms.
Findings:
- The patient's sexual side effects were temporally associated with pregabalin use.
- A reduction in pregabalin dosage led to a decrease in the observed adverse sexual effects.
Implications:
- This case highlights a rare but significant association between pregabalin and sexual disinhibition.
- Increased clinical awareness can facilitate earlier management, potentially through dose adjustment rather than discontinuation.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
