TL;DR  

Research shows that antidepressants offer only modest benefit for many people and may carry important risks, including withdrawal symptoms, emotional blunting, sexual dysfunction (including rare long-term cases), mood switching, and increased suicidal or violent behavior in certain age groups. Observational studies also raise concerns about use during pregnancy. Natural strategies may provide complementary support. Educational only; work with doctors trained in natural healthcare.

Educational only.

Antidepressants are among the top prescribed drugs in the United States.

Use has grown steadily over the past 20 years, yet research shows that their benefits and risks are more complex than many people realize.

Effectiveness: More Limited Than Once Believed

Several large analyses show that antidepressants often perform only slightly better than placebo for mild and moderate depression.

  • A major PLOS analysis (2008) found that drug–placebo differences were “relatively small even for severely depressed patients.”

  • A 2017 BMJ review found that for many patients, improvements were similar to placebo when looking at overall life functioning rather than symptom checklists.

In real-world practice, many people improve — but research suggests that the medication effect may not be as strong as once assumed.

Withdrawal and Discontinuation Symptoms

Newer research shows that withdrawal (sometimes called “discontinuation syndrome”) is much more common and longer-lasting than previously reported.

Earlier clinical trials underestimated this because they only followed patients for a few days.

Emotional Blunting / Reduced Positive Feelings

Modern research confirms a previously underrecognized effect:

This can affect relationships, motivation, and overall well-being.

Sexual Side Effects (Possibly Irreversible)

SSRI-induced sexual dysfunction is well documented:

  • 30–70% of users experience some degree of sexual dysfunction.

More recent research has identified:

  • PSSD (Post-SSRI Sexual Dysfunction):
    Reported in scientific literature (BMJ 202o) as a persistent loss of libido, pleasure, or arousal even after stopping the drug. May possibly cause erectile dysfunction in men.
    This is a significant problem affecting between 30% and 70% of SSRI users. The sexual dysfunction may be permanent.

  • Several Studies Show Sexual Dysfunction with SSRI Use: Recent systematic reviews and case series highlight that SSRIs may lead to persistent sexual dysfunction even after the drug is stopped. One review in the BMJ (2020;368:m754) described persistent loss of libido, genital numbness, and anhedonia in a subset of users. Another 2022 retrospective cohort study in Medicines (Basel) found improvement was difficult to achieve in male patients with PSSD. Diagnostic criteria for PSSD were published in 2022 in Int J Risk Saf Med. These findings reinforce the importance of informed consent and monitoring for sexual health in antidepressant therapy.

Violence, Aggression, and Suicide-Related Risks

Two important research papers raise concerns about how SSRIs may influence behavior in some individuals, especially during the early stages of treatment or after dose changes.

A large, register-based study from Sweden, published in European Neuropsychopharmacology (2020;36:1–9), found an association between SSRI use and violent crime in certain age groups, particularly adolescents and young adults. The increased risk was most evident shortly after beginning treatment or following dose adjustments. This was an observational study, so it cannot prove that the medication caused the behavior, but it highlights the need for careful monitoring in younger populations.

Another study published in the Journal of the Royal Society of Medicine (2016;109(10):381–392) reviewed clinical trials involving healthy adult volunteers — people without depression or other mental illness. The authors found that antidepressant exposure was linked with agitation, emotional instability, impulsivity, and suicidal thoughts in some participants. Because these effects occurred in healthy volunteers, they may reflect direct drug-induced changes in brain chemistry rather than underlying psychiatric illness.

These findings do not apply to everyone, but they suggest that SSRIs may increase the risk of restlessness, aggression, impulsivity, or suicidal thoughts in a subset of users. Major medical guidelines now recommend close monitoring during the first weeks of treatment, particularly in adolescents and young adults, and during any dose changes.

Nutrient Effects 

SSRIs may also affect nutrient status:

  • Lower sodium levels (hyponatremia), especially in older adults

  • Possible impacts on melatonin

  • Possible depletion of B vitamins in long-term users (mixed evidence)

Why Natural Approaches Matter

Because:

  • Effectiveness is modest for many people

  • Withdrawal can be difficult

  • Side effects may be significant

  • Pregnancy research raises concerns

  • Emotional and sexual impacts can affect quality of life

Complementary approaches — diet, movement, stress management, gut health, and targeted nutrients — can offer supportive benefits (read more on natural approaches to mental health).

Do antidepressants work well for most people?

Large analyses show that antidepressants provide only small improvements over placebo for many people, especially in mild or moderate depression. Benefits tend to increase with more severe symptoms.

Can antidepressants cause withdrawal symptoms?

Yes. Newer research shows that withdrawal (also called discontinuation syndrome) is more common and longer-lasting than once believed, with symptoms such as dizziness, anxiety, and mood swings.

What is emotional blunting?

Some people taking SSRIs report feeling “numb” or less able to feel positive or negative emotions. A 2022 Neuropsychopharmacology study found reduced reinforcement sensitivity in healthy volunteers.

Are antidepressants linked with increased suicidal or violent behavior?

Some studies show an association between antidepressants and increased risks of agitation, impulsivity, suicidal thoughts, or violent behavior, especially in adolescents or shortly after starting or changing doses.

What about pregnancy?

Observational studies suggest that SSRI use during pregnancy may be associated with outcomes such as preterm birth, ASD, or ADHD.

Can antidepressants affect sexual function?

Yes. Sexual side effects are common, and rare cases of persistent sexual dysfunction (PSSD) have been reported after stopping SSRIs.
