amitriptyline
Amitriptyline is also known by the old brand name Elavil. It's a tricyclic antidepressant (TCA) that's approved to treat depression. But it's not used as often today for depression because it can cause a lot of side effects, like sleepiness and weight gain. It also has many drug interactions. Even so, amitriptyline is often used off label for other reasons, like nerve pain from diabetes and to help prevent migraines. Amitriptyline comes as a generic tablet that you take by mouth. The brand name Elavil is no longer available.

Pros and cons of Amitriptyline
Pros
- Can start to work within 2 to 4 weeks
- Can take with or without food
Cons
- Has many unpleasant side effects, like dry mouth and sleepiness, and drug interactions
- Not the best choice for people with heart problems, trouble urinating, or glaucoma or older adults
Pharmacist tips for Amitriptyline
- You can take amitriptyline with or without food. If it upsets your stomach, try taking it with food next time. This might help calm your stomach.
- You might start to feel better after about 2 to 4 weeks of taking amitriptyline. But it can take 1 to 2 months to feel the full effect. Keep taking amitriptyline as prescribed, even if you don't improve right away. Tell your prescriber if side effects, like sleepiness, dry mouth, or nausea, bother you too much.
- Don't change your dose or stop taking amitriptyline suddenly without talking to your prescriber first. This can cause uncomfortable withdrawal symptoms like nausea, headaches, body aches, or sleep problems. If stopping is the right choice, your prescriber will help lower your dose slowly to prevent withdrawal symptoms.
- Amitriptyline can make you feel tired, sleepy, and dizzy. Don't drive or do anything that needs your full attention until you know how this medication affects you. These side effects might get better as you continue to take the medication for a few weeks.
- Amitriptyline can make your blood pressure drop when you stand up. This can make you feel dizzy or off balance, which can raise your risk of falling. Get up slowly and hold onto something steady after sitting or lying down. If you keep feeling dizzy after a few weeks or if you fall while taking amitriptyline, tell your prescriber.
- Amitriptyline can sometimes make your skin more sensitive to the sun. This can mean that you can get sunburned more easily. When you go outside, be sure to apply sunscreen and wear protective clothing to help prevent sunburn.
- Antidepressants like amitriptyline can raise the risk of suicidal thoughts. Call 911 right away if you or someone close to you notices unusual changes in your behavior or mood while taking this medication.
- If you have diabetes, ask your care team if you need to check your blood sugar more often while taking amitriptyline. This medication can cause blood sugar to go up or down.
- Tell your healthcare team about all the medications you take or plan to take. This helps them make sure your medications are safe to take together. Amitriptyline can interact with many medications and raise the risk of side effects. Taking it with anxiety medications, opioids, or some allergy medications can make you very sleepy. Monoamine oxidase inhibitors (MAOIs) can also raise the risk of a serious problem called serotonin syndrome.
- If you're pregnant or thinking of becoming pregnant, tell your prescriber. They can talk to you about the benefits and risks of taking amitriptyline while pregnant. Note that mental health problems that aren't treated can be harmful for both you and your baby during pregnancy. Your prescriber can help find the safest option for you.
- Let your prescriber know if you want to breastfeed. Amitriptyline can get into breast milk in small amounts. Your prescriber can explain the risks and benefits of taking this medication while breastfeeding. You can also talk to a lactation consultant about other feeding options.
Risks and warnings for Amitriptyline
Amitriptyline can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Worsening depression or suicidal thoughts and behavior
- Risk factors: Age under 24 years old | History of depression or other mental health conditions
Some people taking amitriptyline for depression might feel worse. This medication can also raise the risk of suidical thoughts or behavior. The risk is highest for people age 24 and younger.
Watch for signs like worsening depression, anxiety, panic attacks, trouble sleeping, or feeling angry or irritated. This is most important during the first few months of treatment or after a dose change. If you or someone close to you notices unusual mood or behavior changes, talk to your care team. Call 911 right away if you have thoughts of hurting yourself.
Serotonin syndrome
- Risk factors: Taking other medications that raise serotonin levels in the brain
Amitriptyline can sometimes cause a serious and sometimes life-threatening problem called serotonin syndrome. This happens when you have too much serotonin in your brain. Amitriptyline can raise serotonin levels.
The risk is higher if you take amitriptyline with other medications that also raise serotonin levels. These include other antidepressants, cough medications with dextromethorphan, and triptans for migraines. Tell your care team about all the medications you take so they can check your risk.
Watch for a high fever, fast heart rate, heavy sweating, stiff muscles, confusion, or restlessness. These can be signs of serotonin syndrome. Stop taking amitriptyline and get medical help right away if you notice these symptoms.
Not for use alone for bipolar disorder
- Risk factors: Personal history of bipolar disorder | Family history of bipolar disorder, depression, or suicide
Depression can sometimes be the first sign of bipolar disorder. Taking an antidepressant like amitriptyline by itself can cause a manic episode in people with bipolar disorder. A manic episode can look like lots of energy, talking rapidly, racing thoughts, and less need for sleep.
Before starting amitriptyline for depression, tell your prescriber if you or anyone in your family has bipolar disorder. They'll check your risk and make sure you get the right care. Amitriptyline isn't approved to treat bipolar depression. Get medical help right away if you or someone close to you thinks you're having a manic episode.
Risk of heart problems, heart attack, or stroke
- Risk factors: History of heart problems | Taking high doses of amitriptyline
Before starting amitriptyline, talk to your prescriber if you have any heart problems or have had a stroke before. They can help decide if this medication is safe for you. Amitriptyline, especially at higher doses, might affect heart rhythm (arrhythmia). Some people taking tricyclic antidepressants like amitriptyline have had a heart attack or stroke.
Let your prescriber know if your heart feels like it's beating oddly while taking amitriptyline. Get medical help right away if you have chest pain, pain in your left arm, cold sweats, or trouble breathing. These can be signs of a heart attack. Also get emergency help if you have signs of a stroke. This can look like a sudden headache, weakness on one side of the body, a droopy face, confusion, or trouble speaking.
Low sodium levels
- Risk factors: Older adults | Medical condition called syndrome of inappropriate antidiuretic hormone (SIADH) | Taking diuretics (water pills) | Dehydrated or low fluid levels in the body
Amitriptyline can sometimes lower the sodium levels in the body. Low sodium can cause headaches, trouble concentrating, memory problems, confusion, weakness, or balance problems. If you notice any of these symptoms, call your prescriber right away.
Risk of seizure
- Risk factors: History of seizures | Taking high doses of amitriptyline
Amitriptyline might raise your risk of seizures, especially at higher doses. This is one of the reasons why you start at a low dose and why your prescriber will slowly raise the dose over time. If you've had a seizure before, talk to your prescriber to make sure amitriptyline is safe for you. If you have a seizure while taking amitriptyline, get medical help right away.
Angle-closure glaucoma in certain people
- Risk factors: History of angle-closure glaucoma | Have narrow-angle eyes but haven't had laser eye surgery for it yet
Antidepressants like amitriptyline can sometimes cause a sudden eye problem called an angle-closure attack. This is more likely in people with narrow-angle eyes who haven't had laser eye surgery. Tell your prescriber if you've had angle-closure glaucoma before.
Call your eye specialist right away if you have signs of an angle-closure attack. This can include sudden blurry vision, severe eye pain, or see halos around lights. This is a serious eye problem that needs urgent medical care.
