Brief summary and core concepts

Amitriptyline is a tricyclic antidepressant often seen under brand names such as Elavil and widely available as a generic in the UK. It alters the activity of brain chemicals including serotonin and noradrenaline. While mood improvement may require several weeks, benefits for sleep or some types of chronic pain can appear earlier.

A fast look at the main details:

  • This medication uses amitriptyline as the active ingredient.
  • Licensed primary indication: depression. Frequently prescribed off label for neuropathic pain, migraine prevention and sleep disturbance linked to pain or low mood.
  • Common tablet strengths available privately in the UK: 10 mg, 25 mg, 50 mg and 75 mg.

For information about adverse clinically relevant drug social interactions in a system describe exchanges between components. see the internal reference on social interactions in a system describe exchanges between components. at Interactions with others and medicines to check.

Medical suggestions and applications

In routine UK practice amitriptyline is prescribed primarily for depressive disorders. Clinicians also use it off label for conditions where its pharmacological profile helps, for example:

  • Prevention of migraine and reduction of a pounding headache frequency.
  • Chronic neuropathic pain such as postherpetic neuralgia or diabetic neuropathy.
  • Persistent sleeplessness associated with pain or low mood when a sedating antidepressant is appropriate.

For obsessive compulsive disorder (OCD) selective serotonin reuptake inhibitors such as sertraline or fluoxetine are generally preferred, or clomipramine under specialist supervision.

Safe use and dosing

Always follow the prescription provided by your clinician and read the patient information leaflet supplied with the medicine. Do not stop or change the dose without professional advice.

Typical dosing approaches used in practice include:

  • Depression: many prescribers start at 25 mg to 50 mg at night and increase gradually where needed, real time monitoring response and follow-on effects.
  • Pain or migraine prevention: low starting doses such as 10 mg to 25 mg at night are common, titrating up according to benefit and tolerability.

Practical points:

  • Taking the tablet at bedtime often reduces daytime drowsiness.
  • Gulp water to help swallow. If you have difficulty swallowing consult your pharmacist for formulation options.
  • Abrupt cessation may cause withdrawal effects. Your clinician will advise a gradual taper if stopping is planned.
  • Avoid alcohol because it enhances sedation. Also discuss grapefruit juice with your prescriber as it can affect blood levels.

If you do not notice improvement after several weeks contact your prescriber rather than adjusting the dose yourself. For dosing in the context of interacting drugs see the section Interactions and medicines to check.

Warning alerts and safety tips

Certain medical histories and conditions require extra care when prescribing amitriptyline. Tell your prescriber about any relevant problems before you initiate the task.

  • Allergies: report any previous reaction to amitriptyline or other tricyclic antidepressants.
  • Heart disease: those with coronary disease, arrhythmias, a recent myocardial infarction or a known prolonged QT interval need specialist assessment.
  • Prostatic hypertrophy, urinary retention and narrow angle glaucoma can be made worse by anticholinergic effects.
  • People with epilepsy, severe liver impairment, thyroid problems or bipolar disorder should be supervised closely.
  • Older adults are more susceptible to confusion, falls, constipation and other anticholinergic effects.
  • In gestation to lactation discuss risks and benefits with your clinician; small amounts pass into breast milk.
  • Do not drive or use machines until you know how this medicine affects your alertness and vision; follow DVLA guidance where relevant.
  • Monitor for any worsening of mood or suicidal thoughts, especially in the first few weeks after starting or when changing the dose.

Short term effects with warning indicators

Many adverse consequences ease with time. Seek immediate medical help for severe or worrying symptoms.

  • Frequently observed mild effects: dry mouth, constipation, drowsiness, blurred vision, dizziness, increased sweating, mild nausea and small changes in weight.
  • Less frequent: tremor, palpitations, confusion, and postural low blood pressure that can cause light headedness.
  • Serious signs that require urgent care: loss of consciousness, severe chest pain, very fast or irregular heart beat, seizures, extreme agitation, allergic reactions or new suicidal thinking.
  • Watch for features of serotonin syndrome when amitriptyline is combined with other serotonergic drugs: agitation, high temperature, muscle stiffness and sweating. If these occur seek emergency care.

Interactions and medicines to check

Provide a complete list of all prescribed medicines, over the counter products, herbal remedies and supplements to your prescriber and pharmacist. Critical exchanges include:

  • Monoamine oxidase inhibitors (MAOIs) such as phenelzine or tranylcypromine, or agents like linezolid and methylene blue. Do not merge without observing recommended washout periods.
  • Other serotonergic medicines: SSRIs (for example citalopram, fluoxetine, sertraline), SNRIs (venlafaxine, duloxetine) and some other antidepressants. Combining increases the risk of serotonin syndrome.
  • Drugs that affect cardiac rhythm or prolong the QT interval, including certain antiarrhythmics, antipsychotics and some antibiotics, can raise cardiac risk when used with amitriptyline.
  • CYP450 inhibitors such as cimetidine, fluoxetine and some azole antifungals may raise amitriptyline concentrations and necessitate dose adjustment.
  • Other sedatives and anticholinergic medicines (benzodiazepines, opioids, first generation antihistamines and bladder antimuscarinics) increase sedation and confusion risk.
  • Substances that change metabolism or effect, for example cigarette smoking or The plant St Johns wort, can alter blood levels; starting or stopping these should be discussed in coordination with your clinician.
  • Avoid alcohol and be cautious with grapefruit juice which can increase blood levels of amitriptyline.

What to do when you miss a dose

In case you forget a dose take it as soon as you remember unless the next dose is due shortly. Do not take two doses at once to make up a missed tablet. If you miss doses frequently talk with your clinician about a different option schedules or aids to improve adherence.

Overdose occurrence and critical incident emergency steps

Excess dose of a drug with tricyclic antidepressants can be life threatening. Symptoms may include profound drowsiness, severe confusion, seizures, abnormal heart rhythm, very low blood pressure, fainting or repeated vomiting.

In an emergency call 999 or go directly to the nearest Accident and Emergency department. For urgent but non life threatening advice call NHS 111. If you suspect an overdosed seek immediate medical attention even if symptoms seem mild at first.

Block a storage solution should balance access and protection. and disposal processes

  • Store at normal room temperature, for example between 20 and 25 degrees C, away from strong light and damp.
  • Do not keep medicines in the bathroom or close to heat sources.
  • Keep all medicines out of the sight and reach of children and animals.
  • Return unused or expired medicines to a pharmacy to ensure safe disposal. Do not dispose of tablets in household rubbish or down the toilet unless the pharmacist advises it.

Quick comparison among other options

The best a different possibility depends on the diagnosis, other health conditions plus the balance of likely benefits and knock-on effects. Options commonly considered in the UK include:

  • SSRIs: sertraline, fluoxetine, citalopram and escitalopram. Often first line for depression and many anxiety disorders due to favorable tolerability.
  • SNRIs: venlafaxine and duloxetine. Duloxetine capsule has specific approvals for some neuropathic pain syndromes as well as depression.
  • Other tricyclics: nortriptyline, imipramine and clomipramine. Nortriptyline may cause fewer anticholinergic effects in some patients; clomipramine is a specialist option for OCD.
  • Neuropathic pain agents: gabapentin and pregabalin, topical lidocaine and some older anticonvulsants. Note that gabapentin and pregabalin are subject to additional prescribing controls in the UK and require careful assessment.
  • For migraine prevention: propranolol, topiramate, candesartan and others, chosen according to coexisting conditions.

When comparing medicines consider side effect profiles, monitoring needs, intercommunication potential and regulatory controls. Peruse the UK price policy and availability section below for a rough comparison of costs.
