Drug family
This medicine is a tricyclic antidepressant, commonly abbreviated as TCA.
Commonly reported cues

Medication dosage forms and strengths
Tablets are sold in multiple strengths such as 10 mg, 25 mg, 50 mg, 75 mg, 100 mg, and 150 mg. Generic tablets are widely available; 50 mg is a frequently used reference strength.
Improvements in sleep or appetite may be noticed earlier than mood changes. Full antidepressant benefit can take several weeks.

What is the right way to take amitriptyline?
- Follow the exact prescription from your clinician and read the printed leaflet that comes with the medicine.
- If the medication increases drowsiness, taking it in the evening may be recommended.
- Do not discontinue suddenly; a gradual taper reduces the chance of withdrawal symptoms such as nausea, insomnia, or agitation.
- If a dose causes stomach upset, try taking it with a small snack. Otherwise it can be taken with or without food.
- Avoid grapefruit and grapefruit juice as they can raise blood levels of many medicines, including some antidepressants.
When in doubt about timing or i forgot to take the doses, consult the counsel on i forgot to take the doses and contact your pharmacist or prescriber for personalized advice.
Process of operation
Amitriptyline increases levels of norepinephrine and serotonin in the brain by inhibiting their reuptake. It also antagonizes histamine and muscarinic receptors, which can improve sleep but is responsible for common anticholinergic effects such as dry mouth and constipation.
Unadministered dose and overdose on medicine
Omitted dose
If you skip taking a dose, take it as soon as you remember, unless the next scheduled dose is near. Do not double the next dose to make up for a missed tablet.
Excessive dose of medication
A suspected suspected overdose calls for immediate medical attention. Signs can include extreme drowsiness, very fast or irregular heartbeat, seizure, difficulty breathing, or loss of consciousness. Call 911 or go on to the nearest emergency department immediately.
Storage and maintenance
Store tablets at room temperature, about 68 to 77 degrees F (20 to 25 degrees C). Temperature fluctuations within the range of 59 to 86 F (15 to 30 C) are permitted. Keep the product away from moisture, excessive heat, and direct light. Do not store in bathrooms. Keep this item beyond the reach of both children and pets. and follow local guidance for safe disposal.
Cautions to observe and warning notices
List of health conditions that forbid use that are strict
- Known hypersensitivity to amitriptyline or any component of the formulation.
- Concurrent use with monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping an MAOI due to risk of severe reactions.
- Recent myocardial infarction unless advised by a specialist; TCAs can affect cardiac conduction.
- Use with drugs that significantly prolong the QT interval should be avoided; see the interacting with others profiles for drugs a portion of the text.
Discuss with your prescriber if you
- Are pregnant, planning pregnancy, or breastfeeding.
- Use prescription, over-the-counter, or herbal products such as St John's wort.
- Have a history of bipolar disorder, mania, suicidal thoughts, or other psychiatric conditions.
- Have glaucoma, urinary retention, enlarged prostate, thyroid disease, liver dysfunction, seizure disorder, porphyria, or known heart disease.
- Consume alcohol regularly or more than three drinks per day.
Boxed warning
Antidepressants in this class carry a boxed warning about an increased risk of suicidal thinking and behavior in children, adolescents, and young adults during initial therapy and dose changes. Monitor for new or worsening mood or suicidal thoughts and contact your clinician promptly if these occur.
Other cautions
- Amitriptyline may cause drowsiness, dizziness, or blurred vision. Do not drive or operate heavy machinery until you know how it affects you.
- Combining alcohol or cannabis with amitriptyline can increase sedation and impair coordination.
- Older adults are more susceptible to anticholinergic after effects; lower starting doses and closer follow up are often necessary.
- Concurrent serotonergic medications raise the risk of serotonin syndrome; check the the study maps how a reciprocal exchanges evolve over time. list.
- If you develop sudden eye pain or acute changes in vision, seek urgent care as angle-closure glaucoma may be precipitated in susceptible people.
Drug risks due to the process of interaction
Provide your prescriber and pharmacist with a full list of medications, vitamins, and supplements. Key interactive engagement groups include:
- Monoamine oxidase inhibitors (MAOIs) such as phenelzine, selegiline, and isocarboxazid: these items must not be combined. within 14 days.
- Drugs that prolong the QT interval (some antipsychotics, certain macrolide antibiotics, some high-dose antihistamines): combined use may increase arrhythmia risk.
- Strong CYP enzyme inhibitors and some antidepressants (for example fluoxetine, paroxetine, fluvoxamine, bupropion, certain azole antifungals): these can raise amitriptyline concentrations and residual effects.
- Anticholinergic medicines (for example scopolamine, bladder antispasmodics): additive dry mouth, constipation, and urinary retention may occur.
- Serotonergic agents (SSRIs, SNRIs, tramadol, triptans, linezolid, St John's wort): coadministration can raise the risk of serotonin syndrome.
- Warfarin: amitriptyline may affect anticoagulant response; monitor INR closely when starting or stopping.
- Thyroid hormones and stimulants (for example levothyroxine, pseudoephedrine): these may increase cardiovascular effects.
- Alpha-2 agonists and some antihypertensives (for example clonidine, guanfacine): the blood pressure lowering effect of these drugs may be altered.
If you experience fainting, palpitations, or severe lightheadedness after starting or changing doses, seek immediate medical attention.
Possible untoward effects
Common and mild by nature
- Lack of saliva along with constipation
- Drowsiness, fatigue, or lightheadedness
- Clouded vision
- Cranial ache
- Nausea or loss of appetite
- Changes in sleep pattern

Other options plus analogous medicines
Selection of an a different possibility depends on symptoms, side effect profile, tracking a mutual exchange of ideass helps measure engagement., and medical history. Options include:
- Other tricyclics: nortriptyline, imipramine, desipramine, doxepin. Nortriptyline is sometimes better tolerated due to lower anticholinergic effects.
- SSRIs: sertraline, fluoxetine, citalopram, escitalopram, paroxetine. These are often first-line because of a more favorable side effect profile for many patients.
- Venlafaxine and duloxetine are included in SNRIs, desvenlafaxine. Duloxetine dosage form has evidence for neuropathic pain and fibromyalgia in addition to depression.
- Atypical antidepressants: bupropion (less sexual accompanying effects, more activating), mirtazapine (sedating and may increase appetite), trazodone (commonly used at low doses for sleep).
- Non-antidepressant agents for pain or prevention: gabapentin, pregabalin, propranolol, topiramate, depending on the condition and tolerability.
