Sinequan is a prescription medicine that is licensed for the treatment of depression and anxiety. It is believed that the medication works by allowing certain chemicals in the brain (serotonin and norepinephrine) to stay in the brain longer. Potential side effects of the antidepressant may include drowsiness, dizziness, or difficulty urinating. While there is currently no brand-name Sinequan available, generic Sinequan is available as capsules and a liquid.
Sinequan® (doxepin hydrochloride) is a prescription medication that is used to treat depression (also known as major depression or clinical depression). It is also approved to treat anxiety.

Sinequan was originally made by Pfizer. However, brand-name Sinequan is no longer available. Generic Sinequan is still available and is made by several manufacturers of generic medications.
How Does Sinequan Work?
Sinequan belongs to a class of medications called tricyclic antidepressants. It is not entirely clear how Sinequan works, but it does affect several chemicals in the brain (including serotonin and norepinephrine). It is thought that perhaps Sinequan allows these chemical to stay in the brain longer, which can help with depression symptoms and anxiety. Sinequan can also block histamine receptors, making it useful as an antihistamine.
