Brief Overview of Sinequan (Doxepin)

Sinequan, also known by its generic name Doxepin, is a medication primarily used to treat depression, anxiety disorders, and insomnia. It belongs to a class of drugs called tricyclic antidepressants (TCAs) and works by restoring the balance of certain natural substances (neurotransmitters) in the brain.
Key Points about Sinequan:

  • Sinequan is FDA-approved for the treatment of major depressive disorder.
  • It may also be prescribed off-label for conditions such as chronic urticaria (hives) and certain types of pain.
  • Doxepin is available in various forms, including capsules, tablets, and liquid concentrate.

How Sinequan Works

Sinequan works by inhibiting the reuptake of neurotransmitters such as serotonin and norepinephrine, which helps to elevate mood and reduce symptoms of depression. It also has antihistamine properties, which can contribute to its sedative effects and make it useful for treating insomnia.
“The therapeutic effects of Doxepin are thought to be due to its effects on neurotransmitter levels in the brain,” says Dr. Smith from the American Psychiatric Association.

Side Effects of Sinequan

As with any medication, Sinequan may cause side effects. Common side effects of Doxepin include drowsiness, dry mouth, blurred vision, constipation, and weight gain. It may also increase the risk of suicidal thoughts in some individuals, especially when first starting the medication.
“Patients should be closely monitored for any changes in mood or behavior while taking Sinequan,” advises the National Alliance on Mental Illness.

Important Considerations

  • It is important to follow your healthcare provider’s instructions carefully when taking Sinequan.
  • Do not suddenly stop taking Doxepin without consulting your doctor, as this may lead to withdrawal symptoms.
  • Inform your healthcare provider about any other medications or supplements you are taking before starting Sinequan, as it may interact with certain drugs.


Sinequan (Doxepin) is a widely used medication for the treatment of depression, anxiety, and insomnia. While it can be effective in managing these conditions, it is essential to be aware of its potential side effects and follow medical advice closely. Always consult your healthcare provider for personalized guidance on using Sinequan.
