How Trazodone works
Trazodone is classified as an atypical antidepressant. More specifically, it's considered a serotonin antagonist and reuptake inhibitor (SARI). The exact way it works to improve your mood isn't well-understood. But it's thought to affect the levels of serotonin in the brain, which are chemicals involved in regulating your mood.

Pros and cons of Trazodone
Pros
- Taken by mouth
- Fewer sexual side effects than some other antidepressants

- Starts to work within a week for treating depression
Cons
- Not a first-choice medication for depression

- Can cause withdrawal symptoms if you suddenly stop taking it
Pharmacist tips for Trazodone
- You can take trazodone with or without food, but if it upsets your stomach, try taking it with food to help. It's best to be consistent with how you take it because food can change how much of the medication is absorbed into your body.
- Trazodone can make you sleepy and dizzy. Avoid alcohol because this can make sleepiness and dizziness worse. Also, don't drive or do anything requiring concentration until you know how this medication affects you.
- Antidepressant medications, like trazodone, might worsen depression. Contact your healthcare professional (HCP) right away if you or your loved ones notice any new or worsening changes in your behavior or mood while taking the medication.
- Don't change your dose or suddenly stop taking trazodone without talking to your HCP first. Doing so can cause bothersome withdrawal symptoms like nausea, headache, and sleeping problems. Follow your prescriber's instructions to lower your dose slowly over a period of time if your goal is to stop the medication completely.
- Trazodone can interact with different medications, which can lead to serious side effects. For example, taking trazodone with sedatives can worsen sleepiness and raise the risk for falls. Taking trazodone with other medications that raises serotonin levels can put you at risk for a serious side effect called serotonin syndrome. Ask your HCP to help you check for medication interactions before starting trazodone.
- If you're pregnant or thinking of becoming pregnant, talk with your psychiatrist or gynecologist about the risks and benefits of using trazodone. Limited studies suggest that trazodone doesn't seem to cause harm when taken by pregnant people, but more research is needed in this area.
- Don't breastfeed while taking trazodone until you've talked to your psychiatrist or gynecologist. Evidence suggests that trazodone can pass into breastmilk, but the amount is low and unlikely to cause harm to a breastfed baby.

Risks and warnings for Trazodone
Trazodone 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, suicidal thoughts, and unusual behavior
- Risk factors: Age 24 years and younger | History of depression or other mental health conditions
Taking antidepressants, like trazodone, might sometimes worsen depression and raise thoughts of suicide or self-harm. The risk is highest for people who are 24 years of age or younger, during the first few months of treatment, and whenever there's a dose change. If you or anyone around you notice that you have suicidal thoughts or unusual behavior (e.g., anxiety, panic attacks, difficulty sleeping, feeling angry or irritated, restlessness) while taking trazodone, get medical help right away.
Serotonin syndrome
- Risk factors: Taking other medications that raise serotonin levels in your brain
Some people taking trazodone have developed a rare, but potentially life-threatening condition called serotonin syndrome. This condition happens where there's too much serotonin in the brain. Your risk for serotonin syndrome is higher if you use trazodone with other medications that can raise your serotonin levels, such as certain antidepressants, mental health medications, and migraine medications. Let your psychiatrist know about all the medications you take before starting trazodone. Symptoms of serotonin syndrome include fast heart rate, sweating, muscle stiffness or spasms, fever, and confusion. Get medical help right away if you have any of these symptoms.
Life-threatening abnormal heart rhythm (QT prolongation)
- Risk factors: Low blood potassium or magnesium levels | Older age | Kidney problems | History of heart problems, slow heart rate, or other abnormal heart rhythms (arrhythmias) | Personal or family history of long QT syndrome | Taking other medications that cause QT prolongation
Trazodone can affect your heart rhythm, which can be serious and life-threatening. One example includes lengthening the time period from when the heart pumps and then relaxes. This is known as QT prolongation. Your risk is higher if you have certain factors, including abnormal electrolyte levels, heart rhythm problems, or are taking other medications that cause heart rhythm problems, such as amiodarone (Pacerone) and ciprofloxacin (Cipro), among others. To lower your risk, your psychiatrist or primary care provider might periodically monitor your heart and perform electrocardiograms (EKGs) to make sure your heart rhythm is normal. If you feel your chest pounding, have shortness of breath, have chest pain, or feel faint or lightheaded while taking trazodone, call 911 right away.
Difficulty concentrating and extreme sleepiness
- Risk factors: Taking high doses of trazodone | Age 65 years or older | Drinking alcohol | Taking other medications that can cause sleepiness
Trazodone can cause extreme sleepiness and lower your ability to think, react, and focus. Your risk is higher if you're also taking other medications that can make you feel sleepy or dizzy. Make sure you know how this medication affects you before driving or doing activities that require your concentration. Talk to your psychiatrist right away if you feel too sleepy from taking trazodone.
Dizziness from lower blood pressure
Trazodone can cause extremely low blood pressure, including a drop in blood pressure when you stand from a sitting or lying down position. This can lead to dizziness and fainting. To avoid falling, get up slowly if you've been sitting or lying down. If dizziness or lightheadedness doesn't go away, talk to your psychiatrist.
Risk of bleeding
- Risk factors: Taking blood-thinners or other medications that raise your risk of bleeding
Trazodone can raise your risk of severe bleeding or bruising, especially if you're also taking antiplatelets (e.g., aspirin, clopidogrel (Plavix)) or anticoagulants (e.g., warfarin (Coumadin), apixaban (Eliquis), or rivaroxaban (Xarelto)). Get medical help if you get bruising that doesn't improve, black-colored stools, pink or red-colored urine, coughing up or vomiting blood, or unusual bleeding from the nose or gums.
Prolonged and painful erection
- Risk factors: Medical conditions that raise the risk of prolonged erections (e.g., sickle cell anemia, multiple myeloma, leukemia, abnormally shaped penis)
Though rare, trazodone can cause prolonged and painful erections, which sometimes require surgery to treat. If you develop a prolonged erection that lasts longer than 4 hours, stop taking trazodone and get medical attention right away.
Glaucoma
- Risk factors: History of angle-closure glaucoma
Trazodone can lead to or worsen angle-closure glaucoma. You might need to see your optometrist regularly and get eye exams to check your eyes and make sure your vision isn't worsening. Contact your psychiatrist or optometrist if you notice changes in your vision after starting trazodone.
Low blood sodium levels
- Risk factors: Older people | Taking other medications that can lower sodium levels
Trazodone might cause low sodium levels in your blood. Get medical help right away if you experience weakness, confusion, difficulty concentrating, headache, or memory problems because these could be signs of low blood sodium levels, which is a medical emergency.
Withdrawal
If you've been taking trazodone regularly, don't suddenly stop taking this medication without checking with your psychiatrist first. If you do, you're at risk for withdrawal symptoms, such as tremor, anxiety, confusion, and seizures. Your psychiatrist can help you stop trazodone safely by slowly lowering your dose over time.
