Silenor is specifically designed to help people with insomnia stay asleep. This prescription medication is believed to work by blocking certain histamine receptors in the body. It is not approved for use in children and adolescents under the age of 18, and there are currently no universally accepted off-label uses for Silenor.
What Is Silenor Used For?Silenor® (doxepin tablets) is a prescription medication approved for the treatment of insomnia that is specifically characterized by difficulty staying asleep. It is not approved for other kinds of insomnia, such as trouble falling asleep.
What Is Insomnia, Exactly?It is not unusual to have trouble sleeping from time to time. This does not necessarily mean that you have insomnia. However, if you feel that you are not getting enough sleep to adequately function during the day, you could possibly have a sleep disorder called insomnia. Insomnia symptoms include:
- Frequently having difficulty falling asleep
- Waking up often during the night and having trouble going back to sleep
- Waking up too early in the morning
- Experiencing non-refreshing sleep.
There are several types of insomnia. These types are often based on how long the insomnia lasts and how often it occurs. Clinical studies have shown that Silenor is useful for treating both temporary and chronic insomnia.
Insomnia can also be categorized by the specific sleep symptoms that occur (such as difficulty falling asleep versus difficulty staying asleep). Silenor is specifically approved for treating insomnia characterized by trouble staying asleep.
How Does Silenor Work?It is thought that Silenor works for insomnia treatment mostly by blocking histamine receptors in the body. Specifically, it blocks a certain type of histamine receptor known as the H1 receptor. Although drugs that block H1 receptors are used for a variety of different purposes, most of them also cause some degree of sleepiness.
Doxepin, the active ingredient in Silenor, is also sometimes classified as a tricyclic antidepressant, an older class of depression and anxiety drugs. In fact, high strengths of doxepin are approved for treating anxiety and depression.
