Trazodone is a medication frequently prescribed to help individuals manage sleep difficulties, particularly insomnia. While generally considered safe when used as directed by a healthcare provider, understanding its effects and considerations for daily administration is important. This article explores what trazodone is, its common effects, and factors for consistent nightly use.
Understanding Trazodone’s Purpose
Trazodone is an antidepressant medication approved by the U.S. Food and Drug Administration (FDA) for treating major depressive disorder. It is commonly prescribed off-label at lower doses for insomnia due to its sedative properties.
The medication’s mechanism of action for sleep involves blocking certain serotonin receptors in the brain, specifically the serotonin 5-HT2A receptor. At doses used for insomnia (25 mg to 100 mg), trazodone also antagonizes histamine H1 and alpha-1 adrenergic receptors. These actions contribute to its ability to induce and maintain sleep.
Common Side Effects with Daily Use
Individuals taking trazodone daily may experience common side effects. Drowsiness or sleepiness is a frequently reported effect, occurring in over 40% of people in clinical trials. This effect is often why it is prescribed for sleep and may lessen as the body adjusts to the medication.
Other common side effects include dizziness, dry mouth, nausea, headache, constipation, fatigue, blurred vision, or a stuffy nose. These effects are usually mild and may become less noticeable over time. Taking trazodone with or after food can help mitigate gastrointestinal upset like nausea.
Long-Term Considerations for Nightly Use
The safety of long-term nightly trazodone use for sleep has limited extensive research, though it is considered safe at low doses. Unlike some other sleep medications, trazodone has a low risk of dependence or addiction. Tolerance, where higher doses are needed for the same effect, is uncommon with long-term use, meaning many individuals can maintain effectiveness at their initial dose for extended periods.
Despite the low risk of addiction, abruptly stopping trazodone after consistent nightly use can lead to withdrawal symptoms. These may include rapid mood swings, irritability, anxiety, agitation, insomnia, dizziness, headaches, and nausea. Therefore, a gradual reduction in dosage under medical supervision is recommended when discontinuing the medication.
A rare but serious side effect associated with trazodone, particularly in males, is priapism, a prolonged and painful erection lasting more than four hours. This condition is a medical emergency and requires immediate attention to prevent permanent damage. The incidence of priapism with trazodone is low, estimated between 1 in 1,000 and 1 in 10,000 male patients, and can occur at any dose or age.
Healthcare professionals monitor individuals on long-term trazodone, assessing for effects such as changes in heart rhythm or low sodium levels. Periodic re-evaluation, typically every 3 to 6 months, helps determine the continued necessity and effectiveness of the medication. A 2020 systematic review advised against long-term trazodone use for chronic insomnia due to its adverse effect profile outweighing its benefits.
When to Consult a Healthcare Provider
Consult a healthcare provider if you experience severe or persistent side effects while taking trazodone, even if they are listed as common. Any signs of an allergic reaction, such as sudden swelling of the lips, mouth, throat, or tongue, or difficulty breathing, warrant immediate medical attention. If you notice yellowing of the skin or eyes, unusual bruising, or an increase in infections, these could indicate more serious issues like liver problems or blood disorders.
Discussion with a healthcare professional is advised if you have concerns about the medication’s effectiveness for sleep, or if you are considering discontinuing trazodone. They can assess your individual situation, adjust dosages, or recommend alternative treatments to ensure your safety and well-being.
