Y49.0: Tricyclic and tetracyclic antidepressants

Tricyclic and tetracyclic antidepressants refer to a group of medications often used to treat certain mood and mental health disorders, like depression and anxiety. These drugs work by adjusting the levels of chemicals in the brain, specifically neurotransmitters, that affect mood and behavior. Although effective, they can sometimes lead to adverse effects in the body, particularly when taken in excess. An overdose of these drugs can present various symptoms such as irregular heartbeat, severe dizziness, severe nausea or vomiting, seizures, hallucinations, and an unsteady walk, amongst others. Prolonged misuse can lead to serious health issues including heart, liver, and kidney problems. It's important to take these medications exactly as prescribed by a healthcare professional to avoid any complications.
