Otc Sleep Aids: Do They Work?

do over the counter sleeping pills work

Sleep is essential for our health and well-being, but for many people, achieving a full night's rest can be challenging. Over-the-counter (OTC) sleeping pills are widely available, but do they really work? OTC sleep aids often contain antihistamines, which can cause drowsiness, or natural supplements like melatonin and valerian, which are generally considered safe for short-term use. While these medications may help with occasional sleeplessness, they are not a cure for chronic insomnia and come with risks and side effects. Experts recommend addressing underlying sleep issues and improving sleep hygiene through lifestyle adjustments as the best long-term solutions for better sleep.

Effectiveness of OTC sleeping pills

Over-the-counter (OTC) sleeping pills are available without a prescription and can be purchased at a drugstore or other retail locations. OTC sleeping pills often contain antihistamines, which can make you drowsy. Some common antihistamines include diphenhydramine and doxylamine. While these medications can help you fall asleep faster, they may not necessarily improve the quality of your sleep.

Additionally, OTC sleeping pills may cause side effects and interact with other medications. It is important to speak to a healthcare provider to ensure that it is safe for you to take these medications and that they will not interfere with any other drugs you are taking. Experts generally recommend that OTC sleeping pills should be a temporary solution for occasional sleeplessness rather than a long-term fix.

Some people also turn to natural supplements, such as melatonin and valerian, to help with sleep. Melatonin is a hormone naturally produced by the brain to control the sleep-wake cycle. It is thought to shift the timing of sleep, and taking it before bed may help you fall asleep a little faster. Valerian is a plant-based sleep aid that has been used for hundreds of years to treat insomnia and anxiety. However, the effectiveness of valerian is unclear, as scientific studies have produced mixed results.

While OTC sleeping pills can be helpful for acute or situational insomnia, they may not be effective for long-term sleep problems. It is important to address the underlying causes of sleep issues and make lifestyle adjustments, such as limiting caffeine and creating a comfortable sleep environment, to improve sleep quality. Additionally, older adults should be cautious when taking OTC sleeping pills, as they may cause confusion, memory issues, and balance problems, increasing the risk of falls and injuries.

Safety and side effects

Over-the-counter (OTC) sleeping pills are generally considered safe for short-term use, but they can cause various side effects, and they may not be suitable for everyone. It is always recommended to consult a healthcare provider or pharmacist before taking any sleep medication, including OTC products.

OTC sleeping pills often contain antihistamines, which can cause drowsiness as a side effect. While this can help people fall asleep, antihistamines are primarily intended to treat allergies, and their use as a sleep aid is not recommended for everyone. Antihistamines can cause serious harm to young children and should never be given to those under two years of age. Additionally, some antihistamines are not suitable for children under six years old. Healthcare providers advise against giving antihistamines to children or teenagers to aid sleep.

Other common side effects of OTC sleeping pills include constipation, diarrhoea, muscle weakness, digestive problems (including gas, heartburn, and nausea), and worsened snoring and sleep apnea. Approximately eight out of ten people experience a "hangover" effect the day after taking sleep medication, feeling drowsy, with muddled thinking, and experiencing dizziness or balance problems. These daytime effects can negatively impact daily activities like driving, working, or studying.

Sleeping pills, in general, carry a risk of dependence and addiction, especially with long-term use. This can lead to increased dosages or abuse of the medication, resulting in more severe side effects. Additionally, some sleeping pills may stop working over time as the body builds a tolerance. Discontinuing the medication can lead to worsened insomnia or withdrawal symptoms.

It is important to note that sleeping pills do not cure insomnia or address its underlying causes. They are typically recommended for short-term relief during difficult periods that temporarily affect sleep. Healthcare providers may suggest alternative treatments, such as sleep therapies, maintaining a consistent sleep schedule, or practising good sleep hygiene (e.g., keeping the bedroom dark and cool, avoiding eating or drinking before bed).

Natural sleep supplements

  • Melatonin: Melatonin is a hormone that is naturally released in the brain about four hours before we feel sleepy. It is triggered by the body's response to reduced light exposure, which should naturally occur at night. However, exposure to artificial light from electronic devices can prevent the release of melatonin, making it hard to fall asleep. Melatonin supplements are available over the counter and can help regulate sleep-wake cycles. It is recommended to consistently buy the same brand of melatonin supplement, as the per-pill dosages and ingredients may differ between manufacturers due to a lack of regulation. While melatonin is generally considered safe for adults in the short term, more research is needed on its long-term effects, especially during pregnancy and breastfeeding.
  • Valerian Root: Valerian is an herb native to Asia and Europe, and its root is commonly used as a natural treatment for symptoms of anxiety, depression, menopause, and sleep disorders. While some studies have shown a minor beneficial effect of valerian root on sleep, results remain inconsistent.
  • Passionflower: Passionflower is another herbal supplement that has shown mixed results in improving sleep quality.
  • CBD: Some studies have found that CBD may relieve anxiety and act as a natural sleep aid, especially when used in combination with THC. However, more high-quality research is needed to confirm these effects, and CBD is not recommended for pregnant or nursing individuals. It is also important to note that CBD is classified as a controlled substance in some states, so its legality may vary.

Other natural sleep aids that have been studied for their potential effectiveness include hops, kava, German chamomile, cherry, tryptophan, theanine, magnesium, and zinc. While these supplements may offer promising alternatives or adjunct treatments for insomnia and sleep disorders, larger, well-designed clinical trials are needed to establish their efficacy and safety.

It is always recommended to speak with a healthcare professional before taking any over-the-counter sleep medication or supplement to ensure it is safe and appropriate for your individual needs and will not interact with any medications you may be taking.

Risks for older adults

While over-the-counter (OTC) sleeping pills are easily accessible, they should be used cautiously, especially among older adults. People aged 65 and older should try non-drug treatments first as there may be safer ways to improve sleep. Sleeping pills have special risks for older adults, and it is recommended to consult a healthcare provider before taking them.

Firstly, older adults are more sensitive to the effects of drugs, and these drugs may linger in their bodies for longer. This exacerbates the risk of falling, causing fractures, and major injuries. Older adults are also more likely to be hospitalised unexpectedly. Observational and case control evidence in older adults also demonstrates an increased hypnotics-associated risk of dementia.

Secondly, side effects of sleeping pills include drowsiness, dizziness, light-headedness, memory loss, poor concentration, and balance problems. These side effects can increase the risk of accidents, especially auto accidents. Moreover, sleeping pills can also cause dependence and addiction, making it difficult to stop taking them without rebound sleep problems or unpleasant 'withdrawal' effects.

Thirdly, sleeping pills suppress breathing and may worsen breathing problems such as sleep apnea. They may also increase the risk of infection and cause problems with thinking and body movement. Some people may experience daytime drowsiness, memory, and physical performance problems. In rare cases, sleepwalking, or even driving, shopping, eating, or making phone calls while not fully awake can occur.

Lastly, a 2014 study found that the risk of developing Alzheimer's disease increased by up to 51% in those who had used benzodiazepines, with the highest risk among those who used them more frequently or took the long-acting ones.

Alternatives to sleeping pills

Sleeping pills can have side effects and risks, and healthcare providers do not recommend using them long-term. Instead, there are several natural alternatives to sleeping pills that can help you sleep better.

Melatonin and Valerian Root Supplements

Melatonin is a hormone that is naturally released in the brain four hours before we feel sleepy. Unnatural light exposure from phones, laptops, or TVs can prevent its release, making it hard to fall asleep. Melatonin supplements are available over the counter and can help with sleep. Valerian root supplements have also shown a minor beneficial effect. However, it is important to note that these supplements are not regulated by the FDA, so dosages and ingredients may vary across manufacturers.

Warm Milk, Chamomile Tea, and Tart Cherry Juice

Warm milk has long been associated with chemicals that simulate the effects of tryptophan, a chemical building block for serotonin, which is involved in the sleep-wake transition. Similarly, chamomile tea is believed to contain flavonoids that interact with benzodiazepine receptors in the brain involved in the sleep-wake transition. Plus, chamomile tea is caffeine-free.

Nondrug Treatments

Sleep problems can often be corrected without medication. Older adults, in particular, should try nondrug treatments first as there may be safer ways to improve sleep. Sleeping pills can cause side effects such as confusion, memory issues, and balance problems, increasing the risk of falls and fractures.
