Tricyclic Antidepressants: Older Medication Class Information and Use Guide
Summary
Tricyclic antidepressants, often called TCAs, are medications used to help manage depression. They are an older class of antidepressants that can be effective but may have more noticeable side effects compared to newer medications. Typically prescribed when other treatments haven't worked, TCAs require careful use and regular monitoring to ensure safety and effectiveness.
What Is This & Why It Matters
Tricyclic antidepressants (TCAs) are medications designed to help improve mood in people with depression. They work by increasing the levels of certain chemicals in the brain that affect mood and emotional state. While effective for many, they are usually a second choice after other treatments due to potential side effects. It's important to understand how these medications work and what to expect while taking them.
What You Should Do
- Take your medication exactly as prescribed by your doctor, usually at bedtime.
- Attend all scheduled follow-up appointments and lab tests, including EKGs.
- Report any unusual symptoms or side effects to your healthcare provider promptly.
- Keep track of any changes in mood or symptoms and inform your doctor during visits.
- Stay hydrated and maintain a balanced diet while on this medication.
- Discuss any other medications or supplements you're taking with your doctor.
What You Should NOT Do
