Amitriptyline: What You Need to Know Right Now

Want a quick, useful rundown of amitriptyline without medical jargon? Here’s a clear guide to what it does, how people usually take it, and the safety checks you should know before you start.

Quick facts & common uses

Amitriptyline is a tricyclic antidepressant that’s been around for decades. Doctors still prescribe it not only for depression but also for nerve pain (neuropathic pain), migraine prevention, chronic pain syndromes, and sometimes insomnia at low doses. It works by boosting serotonin and norepinephrine in the brain and also has strong anticholinergic effects—that explains many of its side effects.

Typical starting doses: for depression, doctors often begin around 25–50 mg at night and increase toward 75–150 mg/day if needed. For nerve pain or sleep help, much lower doses (10–50 mg at night) are common. Older adults usually start even lower—around 10–25 mg—because they’re more sensitive to side effects. Extreme overdose can be life‑threatening; never increase the dose on your own.

Side effects, interactions, and safety tips

Common side effects are dry mouth, constipation, blurred vision, drowsiness, and weight gain. Amitriptyline can also cause dizziness and low blood pressure when standing up (orthostatic hypotension). Because it affects the heart’s electrical system, it can widen the QRS or prolong the QT interval in some people—this is why doctors may order an ECG before or during treatment if you’re older or have heart disease.

Important drug interactions: don’t mix amitriptyline with MAO inhibitors (dangerous reactions can occur), be cautious with SSRIs or SNRIs (risk of serotonin syndrome), and avoid other strong anticholinergic drugs or substances that prolong QT. Alcohol and sedatives increase drowsiness and breathing risk—avoid them while adjusting the dose.

Practical tips: take it at night if it makes you sleepy, swallow whole, and stick to the prescribed schedule. Don’t stop suddenly—tapering helps prevent withdrawal symptoms like nausea, irritability, or flu‑like feelings. If you notice new or worse mood changes, heart palpitations, fainting, or severe constipation, contact your clinician right away.

Pregnancy and breastfeeding: talk to your doctor. Some providers use it when benefits outweigh risks, but decisions depend on your situation and alternatives. If you have glaucoma, enlarged prostate, epilepsy, or serious heart disease, mention that—these conditions affect whether amitriptyline is safe for you.

Finally, always keep a list of your meds and show it to any new provider. Amitriptyline is effective for many people, but its risks and interactions mean it needs careful dosing and follow‑up. If you have questions about side effects or dosage, ask your prescriber—clear, simple answers are what you deserve.
