What is Doxepin?
Doxepin is the active ingredient found inside the brand-name medication Silenor. It belongs to the drug class called tricyclic antidepressants, but some argue that it belongs to the drug class of hypnotics. In the form of Silenor, Doxepin is available in a variety of strengths, including 10, 25, 50, 75, and 100 mg. Each capsule is taken by mouth, metabolized in the liver (while creating metabolites), and excreted through human waste with a half-life averaging at about 15 hours. You will require a valid prescription to obtain this medication.
What is Doxepin used for?
Doxepin (Silenor) is used for the treatment of insomnia. Insomnia is the medical term for difficulties sleeping, which may include a hard time falling asleep as well as staying asleep. Of course, everyone experiences difficulties sleeping at times, but when it lasts for a few weeks, you may have acute insomnia; you may have chronic insomnia if it occurs at least three times per week for three or more months. Using Doxepin can help you fall asleep easier and keep you from waking up throughout the night.
How does Silenor work?
The exact mechanism of action for Doxepin when it comes to insomnia is complex and unclear. Many doctors believe it may be due to the blocking of histamine receptors. Scientists have already concluded that histamine is a chemical that sends signals to the brain to make it awake, which is why blocking histamine receptors may help improve insomnia.
