With this post, we continue our biweekly series on medications used to treat bipolar disorder and related symptoms. This week, we focus the spotlight on medications that can help you sleep.
Before we crack open the medicine cabinet, I’d like to say a few words about bipolar disorder and sleep. Sleep is a biggie. Too much could trigger or be symptomatic of depression. Too little could trigger or be symptomatic of a manic episode. At least one study shows that changes in sleep patterns can be an early predictor of a manic episode. Sleep plays a major role in mood disorders and recovery, so if you’re having trouble sleeping, you and your doctor need to do something about it.
That something could consist of many strategies, ranging from very simple (such as going to bed the same time every night) to more involved – medication, avoiding caffeine and other stimulants, maintaining a strict sleep schedule, and convincing other family members to stop banging around in the kitchen till two in the morning. In stubborn cases, you may benefit from a sleep study to identify factors that may be contributing to the sleep disturbances.
Assuming your doctor and you decide that sleep medication is necessary, your doctor may prescribe one or both of the following:
- A mood stabilizer, atypical antipsychotic, anxiolytic (anti-anxiety agent), or other medication that’s not primarily used for sleep but will hopefully help your sleep if it treats underlying mood or anxiety symptoms. Occasionally these medications are used just for the sedating side effects for sleep, but this is not so common.
- A bona-fide sleeping pill (sedative), which brings us to the main point of this post.
A little-known fact is that the active ingredient in many over-the-counter sleeping pills is diphenhydramine – the generic form of Benadryl!
Several effective sleeping pills are available, which vary in terms of safety, side effects, and other considerations. The following list provides a quick rundown of some of the more common prescription sleep medications currently in use:
- Ambien (zolpidem): Ambien is available in two forms – Ambien (and its generic), which help you fall asleep, and Ambien CR (no generic), approved to help you fall asleep fast and stay asleep. Ambien may not be safe for those who have a history of depression, liver or kidney disease, or respiratory conditions. Ambien may lose its effectiveness if taken longer than two weeks, while Ambien CR can be taken for a longer period of time. Ambien can trigger unusual side effects such as sleep walking, sleep eating, and even sleep driving. Ambien should not be mixed with alcohol – the combination increases the risk of these types of side effects. For more about Ambien CR, visit http://www.ambiencr.com/.
- Lunesta (eszopiclone): Lunesta is approved to help you get to sleep and stay asleep, so you wake up feeling rested. It has a low-risk for developing a dependency, so you can use it short- or long-term, and rebound insomnia (increasing severity of insomnia after stopping the medication) is rare. Lunesta may not be safe for those who have a history of depression, mental illness, or suicidal thoughts; a history of substance abuse or addiction; liver disease; or are pregnant, planning to become pregnant, or breast feeding. Lunesta should not be combined with alcohol. For additional information, visit http://www.lunesta.com/.
- Sonata (zaleplon): Sonata is approved to help you get to sleep. Its particular niche is that it is short acting, so is less likely to produce a hangover effect in the morning. It is so short acting that you can take it a second time if you awaken in the middle of night. Sonata can be habit forming and may not be safe for those who have a history of depression, mental illness, or suicidal thoughts; a history of substance abuse or addiction; severe liver impairment; or are pregnant, planning to become pregnant, or breast feeding. Sonata should not be combined with alcohol.
- Rozerem (ramelteon): Rozerem works differently from other sleep medications and is designed to work in conjunction with your body’s internal clock. It’s non-habit-forming, won’t make you feel groggy the next day, and is safe to use with many prescribed medications. (It’s not a controlled substance like most other prescription sleep medications.) Although Rozerem is generally considered safer and gentler than other prescription sleep medications, it may not be safe for those who have a history of kidney or respiratory problems, sleep apnea, or depression, or are pregnant or breast feeding. It may interact with alcohol, and high-fat meals may slow absorption of the drug. For more about Rozerem, visit http://www.rozerem.com.
Some older sleep aids include Restoril (temazepam), Halcion (triazolam), and ProSom or Eurodin (estazolam). These are not used frequently anymore – and have a history of being addicting and causing a number of side effects. Halcion has been withdrawn form the market in several countries. If your doctor recommends one of these medications, question the reasoning for using an older drug.
Atypical Sleep Aids
Some medications that are not bona fide sedatives are often used for this purpose. Following are a few of the more common and effective medications in this group:
- Trazodone: This is an old fashioned antidepressant, rarely used for depression anymore, but, because it is so sedating, has become popular as a non-habit-forming sleep aid. Its use is limited to women for the most part though, because of a risk in priapism for men – an erection that will not go away. This seems like it might be fun but it is actually a medical emergency.
- Remeron: Another antidepressant used for sleep because it is so sedating, Remeron is pretty effective, but causes weight gain.
- Clonidine: This medication was primarily used for high blood pressure, but is quite sedating, is often used in children with ADHD, and is a good sleep aid that’s not habit forming. It can sometimes cause a drop in blood pressure or rebound high blood pressure. In high doses, it can cause liver problems.
What about melatonin?
Melatonin is a natural hormone, released by the brain when it gets dark. It is available over the counter. It is an effective sleep aid and is well studied even in children. The safety profile is quite good. Doses range from 1-5 mg per night, and it comes in pills and spray forms.
Common Possible Side Effects
All medications have side effects. Prior to taking any prescription or over-the-counter sleep aid, consult your doctor let her know all the medications you are currently taking, including over-the-counter medications and “all natural” or herbal remedies. In addition, be aware that any sleep aid can cause drowsiness, so avoid driving or operating machinery while taking these medications, especially when you first start taking them and are unsure of the effect they may have on you. Additional side effects may include the following:
- Allergic reaction, possibly severe
- Facial swelling
- Prolonged drowsiness (especially the sleep aids designed to help you stay asleep)
- Sleep behaviors, such as sleep-driving and sleep-eating or a combination of the two, like if you sleep drive to McDonald’s
Sleep Aids in My Practice
I recommend or provide sleep aids frequently, because sleep problems are so commonly associated with mood disorders and other psychiatric conditions. I encourage people to practice good “sleep hygiene” as a primary intervention:
- Regular bed time and wake up times
- No stimulants after 12 noon
- No vigorous exercise in the evening
- Turn off screens and phones and work one hour before bedtime
- Try to keep the bed for only sleeping and sex – no work or other activities
- No TV in the bedroom… it’s bad for sleep
If we do need to use a sleep aid, I will often start with melatonin before proceeding to prescription interventions. We try hard to use medications for brief periods of time. Getting enough sleep is important in recovery from mood disorders, so treating aggressively is important.
If you have bipolar and accompanying sleep-related issues, please share your experiences and insights and any helpful suggestions. This goes for you doctors and therapists out there, too!
