The Interplay Between Sleep Disturbances and Medications

The Interplay Between Sleep Disturbances and Medications

On March 15, 2024, people worldwide will celebrate World Sleep Day. In a world where sleep is often sacrificed in the pursuit of productivity, relaxation, or social engagements, the significance of quality sleep cannot be overstated. Each year, on World Sleep Day, we’re reminded of the importance of healthy sleep patterns and their impact on our overall well-being. However, amidst the discussions on sleep hygiene and tips for a restful night, there’s a lesser-known yet crucial aspect to consider: drug-induced sleep disturbances.

World Sleep Day is an opportune moment to illuminate this often-overlooked phenomenon. Drug-induced sleep disturbances occur when medications, whether prescribed or over-the-counter, interfere with an individual’s ability to fall asleep, stay asleep, or achieve restorative sleep. While medication is meant to alleviate symptoms and improve health outcomes, the unintended consequence of sleep disruption can significantly impact one’s quality of life.

Understanding the Complexity of Drug-Induced Sleep Disturbances

The mechanisms behind drug-induced sleep disturbances are multifaceted and vary depending on the type of medication involved. Some medications directly affect neurotransmitters in the brain, altering the delicate balance necessary for initiating and maintaining sleep. For example, certain antidepressants, antipsychotics, and stimulants can interfere with the production or regulation of serotonin, dopamine, or norepinephrine, disrupting the sleep-wake cycle.

Other medications may induce sleep disturbances through secondary effects. For instance, drugs that increase urination, such as diuretics or certain blood pressure medications, can lead to nocturia (excessive nighttime urination), interrupting sleep continuity. Similarly, medications that cause gastrointestinal discomfort or reflux can trigger discomfort during the night, contributing to fragmented sleep patterns.

Common Culprits and Their Impact on Sleep

The list of medications capable of inducing sleep disturbances is extensive and encompasses a wide range of therapeutic classes. Among the most notorious are:

Stimulants, such as those prescribed for attention-deficit/hyperactivity disorder, enhance focus and attention but can cause insomnia if taken too late.

Antidepressants and Antipsychotics are prescribed for depression and anxiety, impacting sleep differently. Some cause insomnia or vivid dreams. Antipsychotics may disrupt sleep due to sedation or metabolic effects.

Corticosteroids, often prescribed for inflammatory conditions such as asthma or autoimmune disorders, can disrupt sleep patterns, leading to insomnia or frequent awakenings.

Beta-blockers, used for hypertension or arrhythmias, can disrupt sleep quality, leading to vivid dreams, nighttime awakenings, or daytime fatigue.

Insights from DrugCard Specialists: A Closer Look at Sleep Disorders and Medication

Specialists on the DrugCard platform highlight the importance of addressing sleep disturbance issues stemming from medication use through their observations in the medical literature. During routine literature reviews, various accounts emerge detailing sleep disorders linked to medication. A recent case involved olanzapine, an atypical antipsychotic.

In this particular case, an elderly individual experienced psychobehavioral symptoms following a sudden cerebral infarction. Initially, these symptoms showed improvement with a nightly dose of 5 mg of olanzapine. However, ongoing use of olanzapine resulted in the emergence of hypersomnia symptoms, which worsened as the olanzapine dosage increased gradually. Notably, the patient had no recollection of these events upon waking, aligning with the recognized olanzapine symptoms.

Instances like these emphasize the necessity for clinical healthcare professionals to exercise heightened vigilance and attentiveness toward this issue.

Dose Matters: Statins and Sleep Disorders

Healthcare providers commonly prescribe statins for high cholesterol, finding them generally well-tolerated with minimal side effects. However, recent literature suggests that certain statins like lovastatin, simvastatin, and rosuvastatin may heighten the risk of sleep disorders.

An intriguing study discovered by the DrugCard platform investigates the link between statin use and sleep disturbances, comparing them to a non-statin control group. Additionally, this study examines the impact of atorvastatin and rosuvastatin on sleep quality. The findings reveal that higher doses (20 mg) of hydrophilic statins, such as rosuvastatin, are more likely to disrupt sleep than lower doses (10 mg). Interestingly, statins, irrespective of their lipid solubility, are linked to sleep issues and insomnia.

Furthermore, the study uncovers that patients taking atorvastatin or rosuvastatin for over three months experience poorer nighttime quality compared to daytime on the Athens Insomnia Scale.

Navigating Drug-Induced Sleep Disturbances

Addressing drug-induced sleep disturbances requires a multifaceted approach involving healthcare professionals, patients, and caregivers. Communication is vital: individuals should openly discuss their medication regimen with their healthcare provider, including any sleep-related issues experienced. Healthcare providers, in turn, should carefully evaluate medication profiles and consider alternative treatment options when appropriate.

For individuals experiencing sleep disturbances due to medication, implementing healthy sleep practices can mitigate some of the adverse effects. Establishing a consistent sleep schedule, creating a conducive sleep environment, and practicing relaxation before bedtime can promote better sleep hygiene. Additionally, adjusting medication timing or dosage under the guidance of a healthcare provider may help minimize sleep disruption while maintaining therapeutic benefits.


In wrapping up, World Sleep Day underscores the paramount significance of prioritizing sleep for our holistic well-being. Also, it serves as a pivotal platform to shed light on the intricate realm of drug-induced sleep disruptions. This celebration underscores the importance of pharmacovigilance and literature monitoring, highlighting the necessity of vigilant surveillance for potential side effects and medication complications. By delving into the underlying mechanisms of these disturbances, we can better understand their complexities. Fostering transparent communication between patients and healthcare providers paves the way for crafting medication plans that safeguard and enhance our restorative sleep patterns.
