Common uses of trazodone
Trazodone is FDA-approved for major depressive disorder (MDD). By modulating serotonin activity, it can lift mood, reduce anxiety, improve sleep quality, and decrease the physical symptoms of depression such as poor appetite and fatigue. Many patients notice less nighttime restlessness as therapy stabilizes. Because it is generally less activating than some other antidepressants, clinicians often choose trazodone when insomnia is a prominent feature of depression.
Outside its labeled use, trazodone is frequently prescribed off-label in low doses for insomnia, especially sleep maintenance insomnia (difficulty staying asleep). It can also be considered as adjunctive therapy in anxiety disorders or post-SSRI/SNRI augmentation. Off-label use should always be supervised by a licensed clinician who can weigh benefits, alternatives, and individual risk factors.
Dosage and direction
Only take trazodone exactly as prescribed. For depression with immediate-release tablets, clinicians often start around 150 mg per day, usually divided into 2–3 doses, and gradually adjust based on response and tolerability. Some patients may require up to 400 mg/day (outpatients), while higher doses are reserved for closely monitored inpatient settings. Extended-release formulations are typically taken once nightly, often starting at 150 mg, with cautious titration. Always follow your clinician’s schedule and do not change your dose on your own.
For insomnia (off-label), prescribers commonly use much lower doses—often 25–100 mg at bedtime—to minimize next-day sedation and reduce adverse effects. Because individual sensitivity varies widely, the lowest effective dose is preferred. To reduce dizziness or lightheadedness, many patients take trazodone in the evening and rise slowly from sitting or lying positions.
Take trazodone consistently, at the same time each day. Extended-release tablets are generally taken at bedtime and should be swallowed whole; do not crush or chew unless your clinician or pharmacist confirms a formulation that allows it. If gastrointestinal upset occurs, taking the medication with a light snack can help. Do not abruptly stop trazodone; your clinician can guide a gradual taper to limit withdrawal-like symptoms.
Precautions
Black box warning: Antidepressants, including trazodone, may increase the risk of suicidal thoughts and behaviors in children, adolescents, and young adults—especially during the first few months of therapy or during dose changes. Watch for sudden mood shifts, increased agitation, or worsening depression, and seek immediate medical advice if these occur. Careful monitoring by a clinician is essential during initiation and titration.
Sedation and dizziness are common, particularly when starting or increasing the dose. Avoid alcohol and be cautious with other central nervous system depressants. Trazodone can cause orthostatic hypotension (a drop in blood pressure when standing), which may lead to fainting or falls—use extra caution in older adults. Until you know how trazodone affects you, avoid driving, operating machinery, or activities requiring full alertness.
Additional risks include serotonin syndrome (especially with other serotonergic drugs), rare but serious priapism (prolonged, painful erections requiring urgent care), arrhythmias/QT prolongation, hyponatremia/SIADH (more common in older adults), and increased bleeding risk when combined with NSAIDs, aspirin, or anticoagulants. Use caution if you have heart disease, a history of bipolar disorder (risk of mania/hypomania), narrow-angle glaucoma, seizures, liver or kidney impairment, or if you are pregnant or breastfeeding—your clinician can discuss risk–benefit and monitoring plans tailored to you.
Contraindications
Do not use trazodone if you have a known hypersensitivity to trazodone or any component of the formulation. Avoid trazodone with monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping an MAOI, due to the risk of severe interactions (including hypertensive crisis and serotonin syndrome). Use extreme caution—and specialist guidance—if linezolid or intravenous methylene blue is required during therapy.
Possible side effects
Common side effects include drowsiness, dizziness, dry mouth, headache, nausea, constipation or diarrhea, blurred vision, and fatigue. Many of these improve as your body adjusts. Taking doses at bedtime and staying hydrated can reduce discomfort. If you experience next-day grogginess, discuss whether a dose adjustment or timing change is appropriate.
Serious adverse effects are uncommon but require prompt attention: chest pain, irregular heartbeat, fainting, severe dizziness, confusion, agitation, fever, shivering, muscle rigidity or tremor (possible serotonin syndrome), severe allergic reactions (rash, hives, swelling, difficulty breathing), unusual bruising/bleeding, severe hyponatremia symptoms (headache, confusion, seizures), or priapism. Seek emergency care for any life-threatening or rapidly worsening symptoms.
Drug interactions
Never combine trazodone with MAOIs and be cautious with other serotonergic agents such as SSRIs, SNRIs, TCAs, triptans, tramadol, linezolid, lithium, or St. John’s wort due to the risk of serotonin syndrome. Alcohol, benzodiazepines, sleep aids, and opioids can markedly increase sedation and respiratory depression. Trazodone may also add to the blood pressure–lowering effects of antihypertensives, increasing dizziness or fainting risk.
Drugs that affect CYP3A4 can change trazodone levels: strong inhibitors (e.g., ketoconazole, ritonavir, clarithromycin, grapefruit juice) may raise levels and side effect risk; inducers (e.g., carbamazepine, phenytoin, rifampin) may reduce efficacy. Use caution with medications that prolong the QT interval (certain antiarrhythmics like amiodarone or sotalol, some antipsychotics and macrolide antibiotics) due to potential additive cardiac effects. Report all prescriptions, over-the-counter medicines, and supplements to your clinician or pharmacist to screen for interactions.
Missed dose
If you miss a dose, take it when you remember unless it’s close to your next scheduled dose. If it is near the time for the next dose, skip the missed dose and resume your regular schedule. Do not double doses. To avoid missed doses, set reminders and take trazodone at the same time each day as directed by your clinician.
Overdose
An overdose may cause extreme drowsiness, confusion, vomiting, low blood pressure, rapid or irregular heartbeat, seizures, difficulty breathing, or serotonin syndrome. Call emergency services or Poison Control (in the U.S., 1-800-222-1222) immediately. Do not induce vomiting unless instructed by a professional. Overdose risk and severity increase with alcohol, benzodiazepines, opioids, or other sedatives—store trazodone securely and never share your medication.
Storage
Store trazodone at room temperature (generally 68–77°F/20–25°C), away from excess heat, moisture, and direct light. Keep it in its original, child-resistant container, tightly closed, and out of reach of children and pets. Do not use expired medication. For safe disposal, use a local drug take-back program or follow FDA/DEA guidance—avoid flushing unless specifically instructed.
U.S. sale and prescription policy
In the United States, trazodone is a prescription-only medication. It is not legal or safe to buy trazodone without a valid prescription. Unregulated online sources that advertise “no-prescription” sales often ship counterfeit or improperly handled medicines, increasing the risk of treatment failure, contamination, or serious harm. Protect your health by obtaining trazodone through licensed clinicians and pharmacies that verify identity, evaluate medical history, and provide ongoing monitoring.
Surgery Center of Pottsville offers a legal and structured pathway to care: you can schedule a visit (in person or via telehealth where permitted) with a licensed clinician who will assess your symptoms, review your medications and conditions, and determine whether trazodone is appropriate. When clinically indicated, prescriptions are sent to reputable, licensed pharmacies for fulfillment—no shortcuts, no gray-market vendors. This approach prioritizes your safety, ensures dose and interaction checks, supports follow-up for efficacy and side effects, and helps you stay compliant with U.S. regulations while getting the care you need.
