Overview and scope
Elavil is a trade name for amitriptyline, a tricyclic antidepressant commonly referred to by its generic name in the United Kingdom. Amitriptyline acts on brain chemicals including serotonin and noradrenaline. Mood improvements can take several weeks to develop, while sleep or pain benefits are sometimes noticed earlier.
- Engaged component: amitriptyline
- Standard medical uses: depressive disorders, prevention of migraine, certain chronic neuropathic pain conditions, and sleep problems linked to pain or low mood
- Common oral strengths found in the UK: 10 mg, 25 mg, 50 mg, 75 mg

Utilization and signs indicating
Amitriptyline is licensed in the UK for the treatment of depression. Clinicians also frequently prescribe it off-label for neuropathic pain, prevention of tension-type head pains and migraine, and to help with sleep disturbances related to pain or mood disorders.
It is not typically a first choice for obsessive compulsive disorder; selective serotonin reuptake inhibitors such as sertraline or fluoxetine, or clomipramine under specialist care, are preferred for OCD.
How to deal with this
Always follow the instructions given by your prescriber. Do not alter the dosage without a medical professional recommendation.
- Start low and go slow is the general approach. Examples:
- Depression: an initial dose often ranges from 25 mg to 50 mg once daily, usually at night, with gradual increases as needed.
- Pain or migraine prevention: lower starting doses such as 10 mg to 25 mg at night are common; titrate according to effect and tolerance.
- Take these tablets with a full glass of water. Taking the dose at bedtime reduces daytime drowsiness for many people.
- Do not stop suddenly; your prescriber will advise a gradual taper to avoid withdrawal symptoms.
- Avoid alcohol while taking amitriptyline because it can enhance drowsiness. Grapefruit juice may increase blood levels and should generally be avoided.
If you have not experienced benefit after several weeks, consult your clinician rather than self-adjusting the regimen.
Safety advisories and cautions
- Inform your prescriber about any previous allergic reactions to amitriptyline or other tricyclic antidepressants.
- Cardiac history: caution is required with heart disease, recent myocardial infarction, arrhythmias or known QT prolongation.
- Conditions such as glaucoma, enlarged prostate or urinary retention can be worsened by this medicine.
- People with epilepsy, severe liver disease, thyroid disorders or bipolar disorder need closer status monitoring.
- Older adults may be more prone to confusion, falls, constipation and other anticholinergic effects.
- Maternal pregnancy and lactation: use only after weighing risks and benefits with your clinician; amitriptyline appears in breast milk in small amounts.
- Do not drive or operate machinery until you know how the drug affects you, as drowsiness and blurred vision may occur.
- Monitor closely for any worsening of mood or suicidal thoughts, especially at treatment initiation or after dose changes.
Short term effects
Negative effects are common but often settle with time. Seek medical attention for severe or persistent problems.
- Frequent but usually mild: dry mouth, constipation, drowsiness, dizziness, blurred vision, sweating, nausea, and minor weight change.
- Less frequent: tremor, confusion, palpitations, and orthostatic hypotension (light-headedness on standing).
- Serious signs requiring urgent care: severe chest pain, fainting, fast or irregular heartbeat, seizuresan implementable solution serotonin syndrome (agitation, fever, rigidity), significant allergic reaction, or new suicidal thinking.
Interactions among users
Tell your prescriber and pharmacist about every medicine, supplement, and herbal product you take. Key interpersonal dialogue and exchange groups include:
- Monoamine oxidase inhibitors (MAOIs) such as phenelzine or tranylcypromine, and certain agents like linezolid or methylene blue. These should not be combined without recommended washout intervals.
- Other drugs that increase serotonin: SSRIs (for example, citalopram, fluoxetine, sertraline), SNRIs (venlafaxine, duloxetine), and some other antidepressants. Combined use may raise the risk of serotonin syndrome.
- Medicines that prolong QT interval or affect heart rhythm, including some antiarrhythmics and certain antipsychotics and antibiotics, can increase cardiac risk when combined with amitriptyline.
- CYP450 inhibitors such as cimetidine, fluoxetine, or some azole antifungals can raise amitriptyline levels and may require dose changes.
- Other sedating or anticholinergic agents (benzodiazepines, opioids, antihistamines, bladder antimuscarinics) can intensify drowsiness, constipation, and confusion.
- Smoking and St Johns wort can alter drug levels. Start or stop these while informing your prescriber.
- Ethyl alcohol drink increases sedation; grapefruit juice can increase plasma concentrations.
Dose missed
If you forget a single dose, take it as soon as you remember unless it is nearly time for the next scheduled dose. Do not take a double dose to make up for one missed.
Emergency guidance for fatal overdose: what to do

Additional choices and a concise comparison
Treatment choice depends on diagnosis, comorbidities and side-effect profile. Possible varied options used in the UK include:
- Other tricyclics: nortriptyline, imipramine, clomipramine (clomipramine is particularly used for OCD under specialist supervision). Nortriptyline is sometimes better tolerated with fewer anticholinergic effects.
- SSRIs: sertraline, fluoxetine, citalopram, escitalopram, paroxetine - commonly first-line for depression and anxiety disorders.
- SNRIs: duloxetine and venlafaxine - used for depression and can help neuropathic pain (duloxetine has specific signs for neuropathic pain).
- Neuropathic pain therapies: gabapentin and pregabalin (note pregabalin and gabapentin are subject to tighter controls in the UK); topical lidocaine and older anticonvulsants are also options.
- Migraine prevention other course options: propranolol, topiramate, candesartan among others chosen based on medical history.
