    What Are Sleeping Pills?

    What Are the Side Effects of Sleeping Pills?

    Usually, sleeping pills are sleep medications that are used to induce sleep and help you stay asleep. They are also commonly referred to as sedatives, sleep aids, sleep medicines or tranquilizers.

    Types of sleeping pills

    Sleeping pills can be broadly categorized into two main categories— prescription sleeping pills and non-prescription sleeping pills.

    Non-prescription sleep medications can be easily found over the counter. They primarily rely on antihistamines as the main ingredient to induce sleep. Some common sleep medicines are diphenhydramine and doxylamine [2].

    Prescription sleep medications are usually classified as sedative-hypnotics. Sedative hypnotics, sometimes called ‘depressants’ work by slowing down brain activity to promote calmness and tranquility for rest. They can be used to treat insomnia and sleeplessness temporarily and help relieve anxiety [3], [4].

    Side Effects

    Different sleeping pills may come with different side effects, but the most common side effects of sleeping pills in the short-term and long-term are as follows [5]:

    Short-term adverse effects

    • Fatigue and excessive sleepiness
    • Headache
    • Confusion
    • Diarrhea or constipation
    • Dry mouth
    • Muscle weakness
    • Stomach problems
    • Memory or performance problems
    • Change in appetite

    Long-term adverse effects

    • Brain degeneration
    • Increased risk of Alzheimer’s disease or dementia

    Short-Term and Long-Term Complications of Sleeping Pills

    Dependency

    Some people may increase their risk of developing a tolerance for long-term use, and when this happens, they will increase their dosage which can cause more problematic side effects. Sleeping pills addiction can cause other problems such as impaired motor coordination or inability to focus on things. 

    Parasomnias

    Certain prescription drugs may induce sleep disorders. For example, the use of Zolpidem for insomnia has been associated with an increased risk of experiencing parasomnias like sleepwalking, sleep talking, sleep eating, and sleep driving.

    Both physicians and users need to be aware of this complication and minimize the likelihood by assessing the patient carefully, identifying potential risk factors, and starting out with low dosage levels [6], [7].

    Rebound insomnia

    Rebound insomnia is a problem with sleeping upon the discontinuation of benzodiazepine-hypnotic drugs. Benzodiazepines affect gamma-aminobutyric acid (GABA) levels, reducing stimulation of the nervous system [8], [9].

    While they may help to relax the body and induce sleep, they also come with a risk of dependence. So, the abrupt discontinuation or going ‘cold turkey’ may result in rebound insomnia or insomnia that is much worse than the original.

    Can sleeping pills cause anxiety attacks?

    Sleeping pills do not cause anxiety attacks in general. However, in some cases, certain individuals may experience increased agitation or nervousness with the use of sleeping pills.

    Anxiety attacks are more likely to occur when you stop taking sleeping pills abruptly. Stopping the use of sleeping pills too fast and after long-term use can cause withdrawal symptoms, one being anxiety or panic attacks [10].

    FAQ

    Generally, taking sleeping pills every night may be bad for you as it can lead to dependency and addiction. You want to use them as directed by your doctor and only for a short period of time.
