Sleep aids or sleep medications are taken by individuals who struggle with occasional sleepless nights or have recurring trouble falling asleep. This may include those with chronic insomnia or other sleep disorders.
When you don’t get enough sleep, it not only affects your energy levels but it predisposes you to several health problems, such as mood problems, poorer concentration times, and an increased risk for hypertension, diabetes, heart disease, and dementia [1].
Stepping into a pharmacy means being greeted by the many shelves lined with over-the-counter sleep aids. With so many options available, it’s understandable that you would feel easily overwhelmed and not know what to pick.
A few common ingredients are typically found in these sleep aids, which we will take a closer look at below.
Diphenhydramine is a type of medicine that is used to relieve itchiness, sneezing, or a runny nose caused by allergies. Besides that, it can also be used to treat symptoms of insomnia. It comes in forms such as tablets, capsules, liquid-filled capsules, dissolving strips, powder, or as a liquid [2].
Melatonin is a hormone that our body produces naturally, but it can come in the form of a supplement as a short-term treatment for insomnia or trouble falling asleep. Melatonin is seen as a natural sleep aid to help regulate the sleep-wake cycle and improve sleep quality [3].
Doxylamine is an antihistamine that is used to treat nausea, vomiting, allergic rhinitis, and insomnia. It can be taken as a tablet or in combination with other medications in the form of a liquid or liquid-filled capsules [4].
If you’re always feeling stressed, nervous or anxious before going to sleep at night, then you might just want to try Hyland’s Calm Forte Sleep Aid Tablets. This gentle, non-habit-forming sleep medicine is a homeopathic formula made with all-natural ingredients to promote relaxation and relieve restless sleep. The passionflower inside helps to treat anxiety and calm restlessness, making it especially ideal for adults who struggle with anxiety.

Over-the-counter sleep aids are generally made to be safe for individuals to take in the short term, but still, there are certain side effects that you should be wary of. Sleep medications and sleep aids that can be bought over-the-counter may have side effects such as daytime drowsiness, dry mouth, or blurred vision.
If you decide to take them, ensure that you are not operating any machinery or doing any activity that requires you to stay alert. It’s also important for you to follow the recommended dosage and always consult a healthcare provider before taking any sleep aids if you have other health conditions or are on other medications.
In general, the American Academy of Sleep Medicine and many doctors do not recommend the use of sleep medications or sleeping pills to help treat poor sleep quality. Instead, the recommended treatment for trouble sleeping is to adopt healthy sleep habits or cognitive behavioral therapy for insomnia (CBT-I) for adults with chronic insomnia [5], [6].
Sleep aids such as over-the-counter sleep medications can potentially help individuals with insomnia and other sleep disorders to relieve sleep problems. However, before taking any sleep medications, you are strongly advised to consult a healthcare provider to determine if you’re suited for it.
