Hyperprolactinemia, a common cause of secondary amenorrhea, can be induced by alprazolam. This case highlights the need for physicians to consider benzodiazepine use when diagnosing elevated prolactin levels.
Area of Science:
- Endocrinology
- Pharmacology
Background:
- Hyperprolactinemia is a frequent cause of secondary amenorrhea, accounting for 20-25% of cases.
- Endocrinologists and expert consensus lists do not typically recognize benzodiazepines as hyperprolactinemia-inducing agents.
Observation:
- A 40-year-old patient presented with spaniomenorrhea and inguinal pain during a bartholinitis episode.
- Moderate hyperprolactinemia was observed, with other known causes ruled out.
- Alprazolam (a benzodiazepine) intake was identified as the likely cause.
Findings:
- This case report documents hyperprolactinemia associated with alprazolam use.
- Bibliographic studies and product characteristics mention this association, though it is not widely recognized by endocrinologists.
- Benzodiazepines are not commonly listed as drugs that induce hyperprolactinemia.
Implications:
- This finding increases awareness among prescribing physicians and biologists regarding potential hyperprolactinemia in patients using benzodiazepines.
- Given the widespread use of benzodiazepines in France, this association warrants consideration in clinical practice.
- Further investigation into the mechanism and prevalence of benzodiazepine-induced hyperprolactinemia may be beneficial.

Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...

Sedatives and Hypnotics Drugs: Miscellaneous Agents
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...
