Insomnia is one of the most common complaints when patients go to their doctors. While it is not a debilitating sickness in itself, insomnia may cause bodily harm in the long run. This condition may cause huge amounts of stress to long-term sufferers which may further lead to stress-related diseases such as cardiac disorders. Furthermore, lack of sleep affects the overall performance of a person’s daily activities including his work, social life and personal life.
While there are many ways to prevent insomnia such as changing your daily habits, sometimes it just wouldn’t work enough for you to get a good night’s sleep. In this article, I will write about over-the-counter or OTC medications which may help you to sleep if you have short-term or transient insomnia.
ANTIHISTAMINES
These medications, which are most commonly used in cases of allergies, are the most common over-the-counter drugs for insomnia. Histamine, a chemical messenger released by the brain during allergic attacks, is also a chemical that promotes wakefulness. By suppressing the action of histamine, antihistamine medications also promote sleepiness. This is why we feel very drowsy every time we take antihistamine medications.
Commonly, the antihistamines sold and marketed today as OTC medications for insomnia normally contains one of these two types:
- Diphenhydramine citrate or Diphenhydramine hydrochloride. Brand names include Nytol, Benadryl, Compoz, and Sominex.
- Doxylamine succinate. Brand names include Unisom Sleeptabs and Nighttime Sleep Aid
While these medications are effective in alleviating symptoms of short-term insomnia, it is not proven to be effective in patients suffering from insomnia for 2 weeks or longer. The main reason for this is the side-effects associated with the long-term use of these OTC sleep aids.
Side Effects of Antihistamines as OTC Sleep Aids
- Prolonged drowsiness that may carry to the next day. This side effect depends on the people who take antihistamines, some of which may display none or severe daytime drowsiness.
- Headaches and feelings of dizziness.
- Dry mouth and throat.
- Reduced alertness and lack of focus, coordination and concentration. Driving is prohibited while you take this medication, as the activity requires you to have mental alertness and coordination.
- Gastrointestinal side effects such as vomiting and constipation.
- While the effects of antihistamine in pregnant or lactating women are still under study, medical practitioners discourage its use during pregnancy. Also, these drugs could be secreted into the milk of lactating mothers which may have harmful effects on the newborn.
Furthermore, it is not advisable for the person who is taking these kinds of OTC sleep aids to drink alcohol because antihistamines add greatly to the sedative effects of alcohol. Taking these kinds of medications with medications that cause drowsiness is also discouraged.
Other Problems Associated with OTC Sleep Aids
For patients who have taken OTC sleep aids for a week or more, they will most likely develop a drug tolerance to it. This means that larger doses of this medication may be required to achieve the desired effect.
Another problem associated with taking OTC sleep aids is the eventual drug dependence of the person taking the medications. A person may not be able to sleep anymore without taking the medication. Abrupt stopping of drug intake may also cause withdrawal symptoms.
