Amoxapine: Uses, Dosage, Side Effects & Interactions

When working with Amoxapine, a tricyclic antidepressant that blocks the reuptake of serotonin and norepinephrine. Also called Dariol, it treats major depressive disorder and is sometimes used off‑label for anxiety. It belongs to the tricyclic antidepressant class, a group that also includes imipramine and amitriptyline. The drug works by increasing levels of serotonin and norepinephrine in the brain, which helps lift mood and reduce anxiety. Oral tablets come in 5 mg, 10 mg and 20 mg strengths; the typical adult dose starts at 100 mg per day and may be raised to 300 mg based on response and tolerance. Because Amoxapine is metabolized by CYP2D6, patients who are poor metabolizers may need lower doses to avoid excess side‑effects. Common side effects include dry mouth, constipation, dizziness and weight gain, while more serious risks involve seizures, orthostatic hypotension and rare cases of blood dyscrasias. Monitoring blood pressure, heart rate and liver function is recommended during the first few weeks, especially for older adults or those on other CNS‑active drugs.

Practical Considerations for Patients and Clinicians

One of the biggest challenges with Amoxapine is its interaction profile. It can raise the levels of other CYP2D6 substrates such as codeine, tamoxifen and certain antipsychotics, so dose adjustments may be needed. Combining it with other serotonergic agents (SSRIs, SNRIs, tramadol) can increase the risk of serotonin syndrome, a condition marked by agitation, fever and tremor. For patients with a history of cardiac arrhythmias, an ECG is wise before starting, because tricyclics can prolong the QT interval. Pregnant or breastfeeding women should only use Amoxapine if the potential benefit outweighs the risk, as limited data exist on fetal safety. When switching from or to other antidepressants, a gradual cross‑taper helps minimize withdrawal symptoms and rebound depression.

Compared with newer agents like SSRIs or SNRIs, Amoxapine often feels more sedating, which some patients appreciate for nighttime dosing but can interfere with daytime activities. Its anti‑psychotic properties (via dopamine blockade) can be useful in patients with comorbid psychotic depression, yet this same action may cause extrapyramidal symptoms such as tremor or rigidity. The key is to match the drug’s pharmacologic profile to the individual’s symptom pattern and health status, rather than applying a one‑size‑fits‑all approach.
