How Long Does Amitriptyline Stay In Your System?
Amitriptyline is a medication primarily used to treat pain and prevent migraine attacks, though it is sometimes prescribed for depression or low mood. As with any medication, it’s important to understand how long it stays in your system, especially if you're considering stopping the medication or preparing for medical tests.
Amitriptyline belongs to a class of drugs known as tricyclic antidepressants. It works by affecting the chemicals in the brain that influence mood and pain. It is often used to treat conditions like chronic pain, migraine prevention, and insomnia, but it can also cause side effects and interact with other medications.
How Long Does Amitriptyline Take to Leave Your Body?
On average, it takes about 10 to 28 hours for half of an Amitriptyline dose to leave your body. This is known as the half-life of the drug, and it’s an important measure when calculating how long the drug remains in your system. For most medications, it takes about five half-lives for the drug to be eliminated entirely from your system.
Therefore, after taking Amitriptyline, you can expect it to stay in your body for around 2 to 6 days. This timeframe can vary depending on factors like your metabolism, kidney function, and the dose you’ve been prescribed. If you have any concerns about how long Amitriptyline may remain in your system, especially if you’re preparing for a drug test or surgery, it’s important to discuss this with your healthcare provider.
Factors That Can Affect How Long Amitriptyline Stays in Your System
Several factors can influence how long Amitriptyline stays in your system, including:
Dosage: Higher doses of Amitriptyline may take longer to be cleared from your body.
Metabolism: Individuals with faster metabolisms may process the drug more quickly than those with slower metabolisms.
Age: Older individuals may experience slower elimination due to changes in liver and kidney function.
Liver and Kidney Function: Since Amitriptyline is metabolised in the liver and excreted by the kidneys, any liver or kidney conditions can affect how long the drug stays in your system.
How to Take Amitriptyline Safely
Amitriptyline should always be taken as prescribed by your doctor. It’s important to follow your doctor’s instructions to avoid any complications or side effects. The typical adult dose ranges from 50mg to 100mg per day, which may be increased gradually to 150mg to 200mg per day if needed. However, the maximum recommended dose is 200mg per day.
It’s also important to remember that Amitriptyline is usually taken at night as it can cause drowsiness. Always swallow the tablets whole, as crushing or chewing them can result in an unpleasant taste.
What If I Miss a Dose?
If you miss a dose of Amitriptyline, take it as soon as you remember, unless it’s almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not take two doses to make up for a missed dose, as this can increase the risk of side effects.
What If I Take Too Much Amitriptyline?
If you take more Amitriptyline than prescribed, it’s important to seek medical help immediately, as an overdose can be dangerous. Warning signs of an overdose include:
Agitation
Shaking
A fast heart rate
Seizures
If you think you’ve taken too much, get medical help right away. Always bring your remaining medication and the details of your dosage to the healthcare provider to help them assess the situation.
Does Amitriptyline Have Any Side Effects?
Like any medication, Amitriptyline can cause side effects. Most people tolerate it well, but some may experience mild effects, especially when they first start taking it. Common side effects include:
Dizziness
Dry mouth
Sleepiness
Tiredness
Weakness
Headaches
These side effects are usually temporary and may improve as your body adjusts to the medication. However, some side effects can be more serious and require immediate medical attention, including:

Yellowing of the skin or eyes
Very dark urine

Confusion
Muscle cramping
Suicidal thoughts
Eye pain or vision changes
If you experience any of these more serious side effects, contact your doctor immediately.
