Sleep Disorders and Medication


Sleep Disorders and Medication

Dr Jonathan Haverkampf

Sleep problems affect many people. Especially in our complex and fast paced world remaining thoughts or emotions from the day can occupy us at night. Dealing with stress effectively, such as prioritizing the activities in one’s life in line with one’s values and interests, can improve sleep considerably. The mental health diagnostic manual DSM-IV defines insomnia as difficulty initiating sleep or maintaining sleep.

Several mental health conditions can also cause sleeplessness. Major depression, PTSD, trauma, anxiety, bipolar disorders, psychosis and many more can cause insomnia. Many organic diseases can also cause insomnia, as can sleep apnea and chronic pain syndromes. In some cases, where no other reason can be found, an idiopathic insomnia may itself be a mental health problem.

The first step is to identify whether there is a sleep problem that requires treatment. People who sleep seven to eight hours usually do not have a problem with lack of sleep. In the case of paradoxical insomnia, although one believes to have a sleep problem, electrophysiological measurements show no sign of a sleep disturbance.

The second step is to identify if there is inadequate sleep hygiene. If there are behaviors that are not conducive to good sleep, they should be addressed first. Some behaviors increase arousal, such as consuming caffeine or nicotine in the evening or at night. Various drugs, legal and illegal, can affect one’s sleep greatly. Intense thoughts or emotions can also disturb one’s sleep, as do day-time naps or significant irregularities in the daily sleep-wake schedule.

Treatment of insomnia should also always include psychotherapy. It can help reduce the worries about and consequences of sleeplessness, and thereby break the vicious cycle of insomnia. Feeling less anxious about the ability to get a goodnight’s sleep often improves one’s sleep. Cognitive therapy, CBT, but also psychodynamic approaches can be helpful.

There are several over-the-counter sleep aids available, often with questionable effectiveness. Nonprescription drugs, such as sedating antihistamines, protein precursors, and a host of other substances can work in individual cases, but they are often not strong enough even in cases of moderate insomnia. L-Tryptophan has been withdrawn from the market after it was linked to outbreaks of eosinophilia. Melatonin may help some individuals, although the placebo should not be underestimated.

Most hypnotics are approved by the U.S. Food and Drug Administration (FDA) only for short-term use. The z-drugs zolpidem (Stilnoct®, Ambien®, Ambien CR®, Intermezzo®, Stilnox® and eszopiclone (Lunesta®), as well as the melatonin-receptor agonist ramelteon (Rozerem®) are exceptions.  The z-drugs are by their function related to the benzodiazepines and are also considered potentially addictive if taken regularly. This means that if they are stopped one’s sleep might be worse for a while. There could also be an additional increase in anxiety and, at least theoretically, panic attacks. Benzodiazepines and z-drugs should not be used while driving a car or operating heavy machinery, and the longer lasting ones can lead to a hangover in the morning and drowsiness during the day.

If the insomnia has lasted for a while and is expected to reoccur for at least a couple of weeks, sleep inducing antidepressants should be considered first choice. Mirtazapine (Remeron®) is often a good option, which in clinical experience is more sleep inducing at lower doses (15mg) than at higher doses (45mg). Second-generation antipsychotics, such as Olanzapine (Zyprexa®) are also used, but it seems there should be some other symptom or reason that justifies their use because of the potentially more serious die-effects. If the insomnia is combined with some types of obsessive thoughts or even Tourette’s syndrome, for example, sleep inducing second-generation antipsychotics may be a logical choice.

Psychotherapeutic treatment of insomnia is discussed in my other articles, but medication as a supportive measure seems warranted in some cases, especially if a modern antidepressant can help the patient maintain a job or a relationship, while using therapy to explore the reasons of the sleep disturbance.

Listed below are some substances that are used to treat insomnia.


  • Zolpidem (Ambien®, Intermezzo®)

They often work quite well, but some patients wake up in the middle of the night. Zolpidem is now available in an extended release version, Ambien CR®. This helps prolong the effect of the medication. The FDA has approved a prescription oral spray called Zolpimist®, which contains zolpidem, for the short-term treatment of insomnia brought on by difficulty falling asleep.

  • Eszopiclone (Lunesta®)

Studies show people sleep an average of seven to eight hours. Because of the risk of impairment, the next day, the FDA recommends the starting dose of Lunesta® be no more than 1 mg.

  • Zaleplon (Sonata®)

Zaleplon stays active in the body for the shortest amount of time. That means patients can try to fall asleep on their own. Then, if they are still not asleep at 2 a.m., they can take it without feeling drowsy in the morning. However, if one tends to wake during the night, this might not be the best choice.

Melatonin-receptor agonist

  • Ramelteon (Rozerem®)

This is a sleep medication that works differently than the others. It works by targeting the sleep-wake cycle, not by depressing the central nervous system. It is prescribed for people who have difficulty falling asleep. Rozerem® can be prescribed for long-term use, and the drug has so far shown no evidence of abuse or dependence.


  • Triazolam (Halcion®)
  • Temazepam (Restoril®)
  • [Alprazolam (Xanax®)]

and others may be useful as an insomnia medication that stays in the system longer. For instance, they have been effectively used to treat sleep problems such as sleepwalking and night terrors. However, these drugs may cause sleepiness during the day and can also cause dependence.


  • Mirtazapine (Remeron®)
  • Doxepine (Silenor®)

This tricyclic antidepressant is approved for use in people who have trouble staying asleep. Silenor® may help with sleep maintenance by blocking histamine receptors. Dosage is based on health, age, and response to therapy. Caution is required with all the tricyclic antidepressants as they can prolong the QT interval and have a number of other potentially severe side-effects.

  • Trazodone (Desyrel®)


Certain antipsychotic drugs like Olanzapin (Zyprexa®) also have a sedative effect and they are sometimes used in slow doses as sleep medication. However, because of the rare but potentially severe side-effects of neuroleptics, even in the second generation, they should not be used as sleep medication without any other rational for using them.

Over-the-Counter Sleep Aids

Most of these sleeping pills are antihistamines. They generally work well but can cause some drowsiness the next day. They are generally considered safe enough to be sold without a prescription. However, if combined with other drugs that also contain antihistamines, like cold or allergy medications, one could inadvertently take too much.

Sleep medication can have a number of side-effects. In 2007, the FDA issued warnings for prescription sleep drugs, alerting patients that they can cause rare allergic reactions and complex sleep-related behaviors, including “sleep driving.” Medication should in the case of a sleeping disorder always be the last option. Better sleep hygiene and psychotherapy/counselling should come long before it and be the first choice. No sleeping pill can take away worries about the job or one’s relationship or correct for drinking coffee in the evening or sleeping next to one’s laptop.
