What Are Antidepressants?

Antidepressants are medications that help relieve symptoms of depression and other mental health conditions such as anxiety . They influence brain chemicals (neurotransmitters) that help regulate mood and other body functions and behaviors . These medications may need to be taken for a few weeks (often four to eight) to fully work .

How Do Antidepressants Work? Antidepressants act on chemical messengers called neurotransmitters, including serotonin, norepinephrine, and dopamine . These neurotransmitters play a role in regulating mood, cognition, behavior, sleep, and memory .

What Is the Best Antidepressant? The best antidepressant depends on individual factors including symptoms, health history, lifestyle, and side effect tolerance . No single first-line antidepressant works better than another, but different ones work better or worse for different people . Finding the best antidepressant often requires trial and error—you may need to try a few different medications before finding the best option for you . The best antidepressant for one patient may not be the best for another. A 2025 Cochrane review found that SSRIs and SNRIs are safe and effective treatments for generalized anxiety disorder, with “high confidence” that antidepressants are more effective than placebo .

Types and Classes of Antidepressants

Selective Serotonin Reuptake Inhibitors (SSRIs)

SSRIs are the most commonly prescribed type of antidepressant . They work by increasing levels of serotonin in the brain and generally have fewer side effects than other types . SSRIs are often the medications of choice for depression and anxiety disorders .

Common SSRIs include: fluoxetine (Prozac), sertraline (Zoloft), escitalopram (Lexapro), paroxetine (Paxil), citalopram (Celexa), and fluvoxamine .

SSRIs are effective in treating depression as well as other mental health disorders that often coexist with depression . The best antidepressant for anxiety is often an SSRI like escitalopram, which is FDA-approved for generalized anxiety disorder (GAD) in patients aged 7 years and older . Escitalopram has demonstrated significant efficacy in treating major depressive disorder, GAD, social anxiety disorder, panic disorder, OCD, PTSD, and PMDD . It is considered one of the better-tolerated SSRIs, with a favorable balance of effectiveness and tolerability .

Serotonin and Norepinephrine Reuptake Inhibitors (SNRIs)

SNRIs are similar to SSRIs but increase both serotonin and norepinephrine levels in the brain . They are also a first-line treatment option .

Common SNRIs include: venlafaxine (Effexor XR) and duloxetine (Cymbalta) .

SNRIs are as effective and safe as SSRIs and have similar side effects . Venlafaxine is FDA-approved for generalized anxiety disorder, panic disorder, and social anxiety disorder in adults .

Atypical Antidepressants

Atypical antidepressants work differently than SSRIs and SNRIs. They may be prescribed when other types don’t work or cause unwanted side effects .

Common atypicals include:

• Bupropion (Wellbutrin): Targets norepinephrine and dopamine; also treats seasonal affective disorder and can help people stop smoking . Less likely to cause weight gain or sexual dysfunction 

• Mirtazapine (Remeron): Sometimes prescribed for people who have trouble sleeping or have lost their appetite due to depression . Has a much more sedating effect, generally reducing its potential to aggravate initial anxiety 

• Trazodone: Also used to treat insomnia and anxiety 

Older Antidepressants

Tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs) are prescribed less often because they tend to cause more side effects . However, they work better for some people .

Primary Uses of Antidepressants

Antidepressants are used to treat conditions beyond depression :

• Major Depressive Disorder (MDD)

• Anxiety Disorders: GAD, panic disorder, social anxiety disorder, OCD, PTSD 

• Premenstrual Dysphoric Disorder (PMDD) 

• Chronic Pain: Nerve pain, migraines, tension-type headaches 

• Insomnia: Trazodone and doxepin are commonly prescribed for sleep 

• Gynecological Pain: Bladder pain, chronic pelvic pain 

The best antidepressant for anxiety and depression is often an SSRI, as these medications effectively treat both conditions with a favorable safety profile .

Advantages and Disadvantages

Advantages

• Proven Efficacy: Antidepressants have helped many people and are considered safe . SSRI/SNRI antidepressants demonstrated that participants had a 41% higher likelihood of achieving anxiety reduction compared to placebo, with “high certainty” evidence 

• Multiple Options: Various classes allow for individualized treatment

• Non-Addictive: SSRIs, SNRIs, bupropion, and mirtazapine are not addictive

• Long-Term Management: Effective for sustained symptom control

Disadvantages and Risks

• Delayed Onset: May take 4-8 weeks to work fully 

• Side Effects: Nausea, weight gain, sleep changes, sexual dysfunction 

• Suicide Risk (Black Box Warning): Increased risk of suicidal thoughts in children, adolescents, and young adults under 25, especially in the early weeks of treatment 

• Discontinuation Syndrome: Abruptly stopping SSRIs/SNRIs may cause withdrawal symptoms 

• Trial and Error: You may need to try several medications to find the right one 

Side Effects

Common Side Effects (by Class)

SSRIs/SNRIs: Nausea, headache, insomnia, weight gain, sexual dysfunction, diarrhea, drowsiness 

Bupropion: Agitation, dry mouth, insomnia; lower seizure risk compared to other antidepressants 

Mirtazapine/Trazodone: Sedation, increased appetite, weight gain 

TCAs: Dry mouth, dizziness, constipation, weight gain, drowsiness 

MAOIs: Significant interactions with foods containing tyramine; can cause hypertensive crisis 

Serious Side Effects

• Serotonin Syndrome: A potentially life-threatening condition that occurs when medications affecting serotonin are combined 

• Suicidal Thoughts: New or increased suicidal thoughts require immediate medical attention 

• Severe Allergic Reactions: Hives, difficulty breathing, swelling of the lips, tongue, or throat

Dosage and Duration

How Long to Take Antidepressants: If you take antidepressants, you should take them for at least 6 months after you begin to feel better to prevent relapse . Most people need to take antidepressants for 6 to 12 months to prevent relapses; people over 50 may need up to 2 years .

When to Expect Results: You may start to feel better within 1 to 3 weeks, but it can take 6 to 8 weeks to see a great deal of improvement . If you have taken the medication for 4-6 weeks without noticing changes, talk to your healthcare provider .

What to Know Before Taking Antidepressants

Conditions to Disclose to Your Doctor:

• Pregnancy/Breastfeeding: Paroxetine should not be used during pregnancy as it may cause heart defects 

• Liver or Kidney Disease: May affect drug metabolism

• Heart Conditions: Higher doses of citalopram may increase risk of heart-related side effects 

• History of Bipolar Disorder: Antidepressants may trigger mania

• Seizure Disorders: Bupropion may lower seizure threshold 

Allergies

If you have a known allergy to any antidepressant or its components, do not take it. Allergic reaction symptoms include hives, difficulty breathing, and swelling of the face, lips, tongue, or throat. Seek emergency medical help immediately.

Time and Instructions of Consumption

• Take exactly as prescribed – dosage is individualized

• Consistency: Take at the same time daily

• Morning or Evening: SSRIs that cause insomnia are best taken in the morning; sedating antidepressants (trazodone, mirtazapine) are best taken at bedtime 

• With or Without Food: Food may reduce stomach upset

• Missed Dose: Take as soon as you remember; if close to next dose, skip

• Discontinuation: Do not abruptly stop; taper under medical supervision to avoid discontinuation syndrome 

Food, Drinks, and Activities to Avoid

Strictly Avoid with MAOIs:

• Foods containing tyramine: aged cheese, red wine, salami, fermented foods, soy sauce, yeast extracts 

• Over-the-counter cold remedies containing pseudoephedrine 

General Recommendations:

• Alcohol: Not recommended due to potential for unpredictable interactions 

• Grapefruit: May interact with certain antidepressants

Drug Interactions

Antidepressants can interact dangerously with many medications:

Genetic Testing for Antidepressants

Genetic testing for antidepressants can help guide treatment decisions. Some research suggests that if one of your parents or siblings responded well to a certain antidepressant, you may be more likely to do well on it, too . Doctors may recommend a test to see how your body metabolizes different medications to help guide your treatment . This is particularly relevant for the strongest antidepressant selection for patients with treatment-resistant depression.

Strongest Antidepressant: While no single strongest antidepressant exists for all patients, clinical evidence suggests escitalopram outperforms most other SSRIs in reducing depressive symptoms, particularly in patients with severe depression . Bupropion/dextromethorphan is in a class by itself and achieves its antidepressant effects through a different mechanism of action .

Best Antidepressant for Women: The best antidepressant for women depends on individual factors including hormonal status, pregnancy considerations, and specific symptom profile. Bupropion is often preferred for women concerned about sexual side effects or weight gain . However, SSRIs are frequently the first choice due to their safety profile . Paroxetine should not be used during pregnancy as it may cause heart defects . A good antidepressant for anxiety and depression like escitalopram is often well-tolerated in women .
