The primary symptoms of menopause are genitourinary and vasomotor. The genitourinary syndrome of menopause (GSM) includes symptoms such as burning, irritation, dryness, dyspareunia, dysuria, and recurrent urinary tract infection. Vasomotor symptoms (VMS; hot flashes, night sweats) often disrupt sleep.

Cognitive behavioral therapy for insomnia (CBT-I) is recommended for initial treatment of chronic insomnia. CBT-I includes stimulus control, sleep education and hygiene, sleep restriction, relaxation training, and cognitive therapy. When CBT-I alone is not effective, pharmacologic treatment should be added.

The FDA has approved daridorexant (Quviviq – Idorsia), an orexin receptor antagonist, for treatment of sleep-onset and/or sleep-maintenance insomnia in adults. Daridorexant is the third orexin receptor antagonist to be approved for this indication; suvorexant (Belsomra) and lemborexant (Dayvigo) were approved earlier.

The primary symptoms of menopause are genitourinary (genitourinary syndrome of menopause; GSM) and vasomotor (VMS). Vulvovaginal atrophy can cause vaginal burning, irritation and dryness, dyspareunia, and dysuria, and increase the risk of urinary tract infections. Vasomotor symptoms ("hot flashes") cause daytime discomfort and night sweats that may disrupt sleep. Hormone therapy is the most effective treatment for both genitourinary and vasomotor symptoms.

The FDA has approved lemborexant (Dayvigo – Eisai), an orexin receptor antagonist, for treatment of sleep-onset and/or sleep-maintenance insomnia in adults. It is the second orexin receptor antagonist to be approved for this indication; suvorexant (Belsomra) was the first.

Cognitive behavioral therapy for insomnia (CBT-I) is recommended for initial treatment of chronic insomnia. Pharmacologic treatment should be used in addition to CBT-I when CBT-I alone is not effective.

The primary symptoms of menopause are genitourinary and vasomotor. A thin, dry vaginal lining and thin urethral mucosa can cause vaginal and vulvar burning and irritation, pain during intercourse, and an increased risk of urinary tract infections. Vasomotor symptoms ("hot flashes") cause daytime discomfort and night sweats that may disrupt sleep.

Pharmacological treatment of insomnia includes prescription drugs, non-prescription medications, and "natural" remedies. Behavioral approaches such as cognitive behavioral therapy, which are not discussed here, are also used. Pharmacologic treatment and behavioral therapy are often combined.

The FDA has approved suvorexant (Belsomra – Merck), the first orexin receptor antagonist to become available in the US, for treatment of sleep-onset and/or sleep-maintenance insomnia.

The FDA has required the manufacturer of eszopiclone (Lunesta – Sunovion), a benzodiazepine receptor agonist approved for the treatment of insomnia, to lower the current recommended starting dose to 1 mg for both men and women because a new study found that an evening dose of 3 mg can impair driving skills, memory, and coordination for more than 11 hours.1 Eszopiclone’s half-life is longer than that of any other drug in its class, which includes zolpidem (Ambien, and generics) and zaleplon (Sonata, and generics).

All benzodiazepine receptor agonists may impair performance the next morning, including driving.2 Anterograde amnesia and complex sleep-related behaviors without conscious awareness may also occur. Hallucinations have been reported. Like the benzodiazepines, benzodiazepine receptor agonists are schedule IV controlled substances; withdrawal, dependence, and abuse can occur.

Pharmacological treatment of insomnia includes prescription drugs, non-prescription medications and "natural" remedies. Behavioral changes are often needed as well.

Zolpidem oral spray (Zolpimist – NovaDel/ECR), a new formulation of the oral hypnotic zolpidem tartrate (Ambien, and others), has been approved by the FDA for short-term treatment of insomnia characterized by difficulty falling asleep.

The FDA has approved a new low-dose formulation of the tricyclic antidepressant doxepin (Silenor – Somaxon) for treatment of insomnia associated with sleep maintenance. The manufacturer claims that this dose retains the hypnotic effect of doxepin, without typical tricyclic adverse effects. Doxepin is available generically in higher-strength capsules and in a liquid formulation.

The majority of patients with insomnia do not have a predisposing psychiatric disease. Rather, untreated insomnia may be a risk factor for development of psychiatric problems such as depression or anxiety.

Many drugs can cause psychiatric symptoms, but a causal connection is often difficult to establish. Psychiatric symptoms that emerge during drug treatment could also be due to the underlying illness, previously unrecognized psychopathology, or psychosocial factors. The withdrawal of some drugs can cause symptoms such as anxiety, psychosis, delirium, agitation or depression.

Many drugs are used to treat insomnia, but for some patients nonpharmacological treatments such as changing sleep habits, relaxation training and cognitive therapy may be more effective and durable than treatment with drugs. Hypnotic drugs are generally FDA-approved only for short-term use, but in practice they often are taken much longer.

Zolpidem (Ambien - Sanofi-Aventis), a nonbenzodiazepine benzodiazepine receptor agonist, is the most frequently prescribed hypnotic in the US. As its patent approaches expiration, its manufacturer has received FDA approval to market an extended-release formulation of the drug, Ambien CR. The pharmacological rationale for doing so is that short-acting hypnotics like zolpidem are more effective at inducing sleep than they are at maintaining it.

Ramelteon (Rozerem - Takeda), a melatonin receptor agonist, has been approved by the FDA for treatment of insomnia characterized by difficulty falling asleep. Unlike all other prescription hypnotics, which are classified as schedule IV drugs, ramelteon is not a controlled substance.

Eszopiclone (Lunesta - Sepracor), a benzodiazepine-like drug, has been approved by the FDA for oral treatment of insomnia. It is the S-isomer of zopiclone (Imovane, and others in Canada), which has been available in other countries for almost 20 years. Unlike similar drugs such as zolpidem (Ambien) or zaleplon (Sonata), Lunesta is not being restricted in its labeling to short-term use. Like other hypnotics, eszopiclone is a schedule IV drug.
