Elavil (Amitriptyline) Dosage Guide

What Is Elavil (Amitriptyline) & How Is It Used?

Amitriptyline, commonly known as Elavil, belongs to a class of medications that help to alleviate symptoms of depression.¹ This drug is primarily prescribed to treat various forms of depression, particularly endogenous depression, which is a type of depression believed to be caused by internal factors, such as genetics or biological imbalances, rather than external life events.

However, it’s worth noting that amitriptyline is sometimes used off-label, meaning it’s utilized for conditions not officially approved by the FDA. Prescribers may choose to do this when they believe the medication could provide benefits to patients. Off-label uses of amitriptyline can include:²

• Anxiety
• Chronic pain syndrome
• Insomnia

Always consult your healthcare provider for guidance on amitriptyline’s appropriate use for your specific needs.

Amitriptyline Forms & Strengths

Amitriptyline is available in various forms and strengths, including tablets and oral solutions, ranging from 10 mg to 150 mg. The choice of form and strength is determined by factors like the patient’s age, the specific condition being treated, and individual response to the medication. Prescribers consider these factors to tailor the treatment to each patient’s unique needs, taking into account factors such as ease of administration and the desired therapeutic effect.

Amitriptyline is available in the following forms and strengths:¹

• 10 mg
• 25 mg
• 50 mg
• 75 mg
• 100 mg
• 150 mg

Remember to take your medication as prescribed by your healthcare provider for optimal results. If you have any questions about usage, consult your healthcare professional.

How to Take Amitriptyline?

Your first dosage will be low, gradually being increased under your doctor’s guidance. For adults, this might mean beginning with 75 mg daily, potentially up to 150 mg. Be patient, as the sedative effect can precede the antidepressant benefits, which may take weeks or longer.

Hospitalized patients might start at 100 mg daily, going up to 200 mg or 300 mg if needed. Adolescents and the elderly usually need lower doses, like 10 mg three times a day and 20 mg at bedtime if higher doses aren’t tolerated.¹ After improvement, a common daily dose is 50-100 mg. Always follow your doctor’s advice when taking amitriptyline.

Amitriptyline Dosage for Adults With Depression

Amitriptyline is prescribed as a treatment for major depressive disorder in adults, offering relief from depressive symptoms and promoting improved mental well-being.

Here is amitriptyline dosage information for adults with depression:¹

• Typical starting dosage: Most adults with depression begin with 75 mg of amitriptyline HCl each day, taken in separate doses.
• Dosage increases: If needed, the dosage can be increased up to a maximum of 150 mg per day. These increases are often done in the late afternoon and/or bedtime doses, and it’s important to note that the sedative effect may be noticeable before the antidepressant benefits, which may take up to 30 days to appear.
• Maximum dosage: In some cases, hospitalized patients may require an initial dosage of 100 mg per day, with gradual increases up to 200 mg daily if necessary. A small number of hospitalized patients may need as much as 300 mg per day to effectively manage their symptoms of depression.

Amitriptyline Dosage for Older Adults With Depression

Amitriptyline can effectively treat elderly adults with depression. However, the dosage for older individuals may differ from the standard adult dosage due to potential differences in metabolism and tolerance levels.

Here is amitriptyline dosage information for older adults with depression:¹

• Typical starting dosage for older adults: Typically, lower doses are advised for elderly patients with depression. A common starting dosage is 10 mg, taken three times a day, along with an additional 20 mg at bedtime.
• Dosage increases: Dosage increases for older adults should be carefully monitored, considering their potential sensitivity to medications.
• Maximum dosage for older adults: There isn’t a fixed maximum dosage for older adults, but it’s crucial to prioritize their safety and closely observe their response to the medication. Individual tolerance and response vary, and adjustments should be made based on their specific needs and any potential side effects.

Amitriptyline Dosage for Children & Adolescents With Depression

Amitriptyline can be used to treat depression in adolescents, but it is not recommended for depression in children under 12 years of age due to limited experience with the medication in this age group. Dosage for adolescents may vary from the standard adult dosage, depending on individual needs and responses.

Here is amitriptyline dosage information for adolescents with depression:¹

• Typical starting dosage for adolescents: Adolescents with depression often begin with lower doses for safety and tolerance reasons. A common starting dose is 10 mg taken three times a day, with an additional 20 mg at bedtime.
• Dosage increases for adolescents: Dosage increases in adolescents should be approached cautiously, considering their unique sensitivities to medications.
• Maximum dosage for adolescents: There isn’t a fixed maximum dosage for adolescents, but careful monitoring and individualized adjustments are essential

What to Avoid When Taking Amitriptyline

Amitriptyline should not be taken with certain other medications called monoamine oxidase inhibitors (MAOIs). These combinations can lead to dangerous reactions, including high fever, severe seizures, or even death. If someone needs to switch from an MAOI to amitriptyline, doctors typically wait at least 14 days after stopping the MAOI before starting amitriptyline, and they begin with a low dose, gradually increasing it to find the right level.¹

Additionally, using amitriptyline with Cisapride (gastrointestinal medication) should be avoided because it can potentially affect the heart’s electrical activity, increasing the risk of irregular heartbeats. Lastly, this medication isn’t recommended for use immediately after a heart attack as it may not be safe during the early recovery phase. Always consult with a healthcare provider to ensure the safe and appropriate use of amitriptyline.

What if I Miss a Dose of Amitriptyline?

Missing a dose of amitriptyline can lead to antidepressant discontinuation (withdrawal), especially if you stop taking it abruptly. These effects might include irritability, mood swings, sleep disturbances, headache, dizziness, nausea, and flu-like symptoms. To get back onto the prescription regimen, it’s important to take the missed dose as soon as you remember unless it’s close to the time for the next dose.

Some might discontinue when they start feeling better, thinking they no longer need the medication. Others may stop due to the initial side effects experienced during the first weeks. However, these side effects often subside as the body adjusts to the medication. If you’re considering stopping or tapering off amitriptyline, it’s essential to consult your doctor to develop a safe and gradual plan to minimize withdrawal effects and maintain your mental health stability.

Amitriptyline Withdrawal

Amitriptyline is not associated with addiction, but stopping it suddenly can lead to withdrawal symptoms, often called antidepressant withdrawal. If you want to discontinue the medication, it’s important to work with a healthcare professional to gradually reduce the dosage and manage any potential withdrawal effects.

Symptoms of withdrawal from amitriptyline include:¹

• Nausea and vomiting
• Headache
• Malaise (general discomfort)
• Irritability
• Restlessness
• Disturbed dreams
• Sleep disturbances
• Dizziness or lightheadedness
• Flu-like symptoms
• Anxiety or nervousness

If you’re considering discontinuing it, it’s essential to consult your healthcare provider. They can guide you in developing a plan to gradually reduce the medication’s dosage, which helps to prevent or minimize withdrawal symptoms.
