Doxepin is a tricyclic antidepressant that is often prescribed to treat both depression and anxiety in chronically distressed patients. This medication works by adjusting the chemical balance in the brain so that the patient feels calmer and happier. Patients on this medication generally feel less stress and negative emotion.
This medication can cause physical addiction and tolerance issues. Physical dependence occurs when the brain and body get used to the presence of the drug; the body fails to function normally without it and as a result, the patient suffers from serious physical and mental illnesses such as high blood pressure, seizures and severe mood swings. Tolerance occurs when the patient begins to require greater doses of the drug to achieve the same effect. Patients should not change their dosage without consulting their doctors because of the risk of addiction or overdose. Patients should also not abruptly stop using this drug.
Some patients are prone to suicidal thoughts and feelings while on this drug. Patients who are younger than 24 years of age are especially prone to this side effect.
