Tricyclic Antidepressants: What They Are and How They Work

When dealing with tricyclic antidepressants, a class of older mood‑lifting drugs that block the reuptake of serotonin and norepinephrine. Also known as TCAs, they were first introduced in the 1950s and still pop up in treatment plans today. Depression, a common mental‑health condition marked by persistent low mood and loss of interest often triggers a prescription for a TCA, especially when newer antidepressants haven’t helped enough. One of the most familiar names in the group is amitriptyline, a widely used TCA that also doubles as a pain reliever, making it a go‑to for many doctors. Beyond mood, neuropathic pain, pain caused by nerve damage that often resists simple analgesics can improve noticeably with a low‑dose TCA, which is why you’ll see that indication mentioned alongside depression in many guides. The core idea is simple: raise the levels of serotonin and norepinephrine in the brain, which helps lift mood and dull painful signals.

How TCAs Differ From Modern Antidepressants

Unlike selective serotonin reuptake inhibitors (SSRIs) that target just one neurotransmitter, TCAs hit both serotonin and norepinephrine pathways. That broader reach can mean stronger effects, but it also brings a wider side‑effect profile. Typical side effects include dry mouth, constipation, blurred vision, and a noticeable drop in blood pressure when you stand up—what doctors call orthostatic hypotension. Because TCAs also block certain cardiac sodium channels, they can change heart rhythm, so patients with existing heart issues need careful monitoring. Dosage matters a lot: a start‑low‑go‑slow approach reduces the risk of dizziness or severe anticholinergic symptoms, and many clinicians prefer to keep the dose just enough to relieve symptoms without cruising into the higher‑risk range.
