Doxepin
Summary
Doxepin is used to treat depression and anxiety, which are mental health conditions causing persistent sadness and worry. It also helps with insomnia, which is difficulty sleeping, due to its calming effects.
Doxepin works by affecting neurotransmitters, which are chemicals in the brain that help regulate mood and anxiety. It blocks the reuptake of norepinephrine and serotonin, which are chemicals that affect mood, allowing them to stay longer in the brain.
The usual starting dose for adults is 25 mg to 50 mg daily, taken in the evening. The maximum dose is 300 mg per day. For elderly patients, a lower starting dose is often used. Always follow your doctor's specific dosing instructions.
Common side effects of Doxepin include drowsiness, which is feeling sleepy, dry mouth, which is a lack of saliva, and dizziness, which is feeling lightheaded. These effects are usually mild and vary among individuals.
Doxepin can increase the risk of suicidal thoughts, especially in young adults. It should not be used if you have untreated narrow-angle glaucoma, which is increased eye pressure, or severe urinary retention, which is difficulty urinating.
