Executive summary

Amitriptyline, often seen under the trade name Elavil and widely supplied as generic amitriptyline hydrochloride, is part of the tricyclic class of antidepressant medicines. It works by modifying neurotransmitter signalling in the brain and spinal cord, mainly affecting serotonin and noradrenaline pathways.

In Australia clinicians prescribe amitriptyline for depressive disorders and for several types of chronic pain. At lower doses it is commonly used for neuropathic pain and for preventing migraine. For some signs that point to other medicines may be preferred; see the section on Alternative drugs and similar pharmaceutical options for options and comparisons.

The active ingredient and its strengths

The active substance is amitriptyline hydrochloride.

Standard tablet strengths supplied in Australian pharmacies include 10 mg, 25 mg, 50 mg and 75 mg. Multiple generic manufacturers produce different pack formats and presentations, so tablets and packaging may vary between brands.

Use cases and tips

Amitriptyline is used for both licensed and off-label purposes. Routine applications in medicine are listed below.

  • The condition referred to as major depressive disorder and related depressive episodes.
  • Neuropathic pain conditions; often effective at doses lower than those used for mood disorders.
  • Prevention of migraine and some types of chronic tension head pain.
  • Functional pain syndromes, including certain visceral pain presentations and painful diabetic neuropathy.
  • Short term treatment of insomnia when a sedating antidepressant is appropriate.

When obsessive compulsive disorder is the main problem, clinicians typically favour SSRIs or clomipramine; see Replacement choices and analogous medicines for comparison.

Dose delivery and administration

Follow the how to dose from your prescriber. The required dose depends on the condition treated, age, other medical problems and concurrent medications.

  • Depression: starting doses commonly 25 to 50 mg at night, with gradual increases. Many adults stabilise between 75 and 150 mg daily; specialist supervision may be needed for doses up to 200 mg.
  • Neuropathic pain and migraine prevention: low-dose regimens are usual. Initiate at 10 to 25 mg at bedtime and titrate slowly, often by 10 to 25 mg every 1 to 2 weeks. Typical analgesic doses are 25 to 75 mg at night.
  • Elderly or frail patients: start very low, for example 10 mg at night, and increase cautiously to reduce adverse sequelae.

Because amitriptyline commonly causes sedation, it is usually taken in the evening. Avoid alcohol during therapy. Grapefruit juice may interfere with drug metabolism and is best avoided. Do not stop treatment abruptly; reduce the dose gradually over at least one to two weeks unless your prescriber advises otherwise. Antidepressant benefit can take several weeks to emerge, while improvements in sleep or pain may be noticed earlier.

Switching between amitriptyline and a monoamine oxidase inhibitor requires careful washout periods. For more information, consult the Medications and dietary factors tracking the back and forth of communications helps measure engagement. the current section.

Risk warning signals and safety instructions

Discuss the following with your prescriber before you begin the task amitriptyline.

  • Hypersensitivity: do not take if you are allergic to amitriptyline or other tricyclic antidepressants.
  • Cardiac disease: previous myocardial infarction, heart failure, arrhythmias or conduction disturbances may require ECG continuous monitoring and dose adjustments.
  • Anticholinergic risks: amitriptyline can precipitate narrow angle glaucoma, worsen urinary retention and cause dry mouth and constipation.
  • Seizure risk: tricyclics may lower the seizure threshold; epilepsy requires careful management.
  • Hepatic and thyroid disease: liver impairment and untreated thyroid disorders can change how the drug is handled and may need closer supervision.
  • Suicidal thoughts: monitor for worsening depression, emergence of suicidal ideas or unusual behavior, particularly after starting or increasing the dose.
  • Gestation and lactation: treatment decisions balance maternal benefit and fetal or infant exposure; amitriptyline is detectable in breast milk in small amounts — discuss choices in meeting with your clinician.
  • Older adults: increased risk of sedation, confusion, falls and urinary problems; "start low and go slow" is recommended.

Side effects

Many ripple effects improve over time as the body adjusts. Commonly reported effects include:

  • Sleepiness, dizziness, lightheadedness and a headache.
  • Parched mouth, blurred vision, constipation and difficulty passing urine.
  • Nausea, appetite or weight changes and increased sweating.
  • Occasionally increased anxiety or restlessness when treatment starts.

Obtain prompt medical assistance for your symptoms. severe or life threatening signs such as:

  • Fainting, severe palpitations or irregular heartbeat.
  • Marked confusion, severe agitation, psychosis or seizures.
  • Possible serotonin syndrome when combined with other serotonergic drugs: high fever, muscle stiffness, tremor, diarrhea and altered mental state.
  • Severe allergic reactions including swelling of the face or throat, widespread rash or difficulty breathing.

If you develop worrying symptoms contact your pharmacist or doctor without delay.

Interaction between drugs and food

Tell your prescriber and pharmacist about all prescription, over the counter, herbal and recreational substances you use. Important communication in action points include:

  • Monoamine oxidase inhibitors (for example tranylcypromine, phenelzine): combining these with amitriptyline can be dangerous. Observe required washout intervals.
  • Other serotonergic medicines (SSRIs, SNRIs, tramadol, Herbal remedy St Johns wort): coadministration increases the risk of serotonin syndrome. Some SSRIs may also raise amitriptyline levels.
  • Drugs that affect cardiac conduction or prolong the QT interval (certain antiarrhythmics and antipsychotics): combined use can increase the risk of arrhythmias.
  • CYP450 inhibitors and inducers (for example fluoxetine, paroxetine, bupropion, cimetidine): these can change blood concentrations of amitriptyline.
  • Other anticholinergic medicines and central nervous system depressants (oxybutynin, benzodiazepines, opioids, sedating antihistamines): additive treatment side effects such as sedation and urinary retention are possible.
  • H2 blockers like cimetidine may elevate amitriptyline levels; ranitidine and famotidine have less effect but caution is advised.

Avoid alcohol because it potentiates sedation. Changes in smoking status can alter drug metabolism; tell your clinician if you start or stop smoking. Grapefruit and grapefruit juice can interfere with metabolism and are best avoided.

Guidance for a dose was not taken

If you miss a dose take it as soon as you remember unless the next scheduled dose is close. Do not double dose to make up for a prescribed dose was missed. If you are unsure contact your pharmacist or prescriber.

Response to an take an overdose items

An amitriptyline experienced an overdose can be life threatening and requires urgent medical care. In Australia call 000 for emergency services or land on the nearest hospital emergency department. Symptoms of experienced an overdose may include extreme drowsiness, vomiting, confusion, very fast or irregular heartbeat, low blood pressure, seizures and unconsciousness. If possible take the medication packaging with you to the hospital.

Estimated private fair a price comparison for a one month supply (indicative only):

  • Amitriptyline 10 to 25 mg nightly: roughly AUD 10 to 25 privately; may be PBS subsidised for some clues indicating.
  • Nortriptyline (a related tricyclic, sometimes better tolerated): around AUD 12 to 30 privately.
  • Duloxetine product (an SNRI used for depression and some pain states): often PBS listed for particular pointers; private cost commonly AUD 25 to 50.
  • SSRIs such as sertraline or escitalopram: many are PBS listed, so the PBS co-payment applies when used for approved reasons.

With time, prices change. Ask your pharmacist for current costs and whether your prescription qualifies for PBS subsidy or the PBS Safety Net.
