Antidepressants Show Vast Differences in Physical Side Effects
For the first time, antidepressants have been ranked according to their physical health effects. This sheds light on major variations among widely used medications. Researchers from King’s College London and the University of Oxford analyzed over 150 studies involving 30 antidepressants and more than 58,000 participants. The findings, published in The Lancet, reveal notable differences in how these medications influence body weight, heart rate, and blood pressure.
In just eight weeks of treatment, some drugs caused patients to gain nearly $2,000 worth of body mass equivalent in food intake. Others, however, led to modest weight loss. For example, agomelatine was linked to a 2.4 kg weight drop. In contrast, maprotiline caused nearly 2 kg of gain in the same period. Meanwhile, fluvoxamine slowed the heart by as much as 21 beats per minute. By comparison, nortriptyline sped it up by the same margin. These physiological shifts can have a substantial impact on long-term cardiovascular health, especially among those predisposed to heart disease or metabolic issues.
Medical experts from the National Health Service (NHS) emphasize that these variations should guide clinicians. They should aim for more personalized antidepressant prescriptions.

Matching Antidepressants to Personal Health Profiles
The study highlights that no two antidepressants are alike. Each comes with unique benefits and potential risks. For instance, while amitriptyline may elevate weight, heart rate, and blood pressure, it remains an effective option for individuals who also struggle with chronic pain or insomnia. Meanwhile, SSRIs such as sertraline, citalopram, and escitalopram tend to have fewer physical side effects and remain the most prescribed options worldwide.
Experts suggest using individualized treatment strategies to ensure the right balance between mental and physical health. At Mayo Clinic’s Depression Center, clinicians recommend close monitoring of physical parameters when patients begin antidepressant therapy.
To illustrate, consider three individuals diagnosed with depression: Sarah, who wishes to avoid weight gain; John, who manages high blood pressure; and Jane, who is concerned about cholesterol. Each would likely benefit from a different medication tailored to their medical history and personal priorities.
Toward Personalized and Sustainable Mental Health Care
The study also criticizes the current “one-size-fits-all” prescribing model. It notes that 85% of antidepressant prescriptions in the UK involve just three generic SSRIs. Implementing these new findings could reduce that dominance and lead to broader, more personalized treatment plans.
Experts from Harvard Health Publishing emphasize that proper medication choice can dramatically improve treatment outcomes. Additionally, it can minimize long-term risks such as cardiovascular disease or metabolic disorders.
Furthermore, the research team is developing a free online tool to help doctors and patients select the right antidepressant based on health metrics and side-effect profiles. This resource is expected to complement existing platforms like the National Institute of Mental Health. It will offer a more data-driven approach to medication management.
Although the study only measured effects within the first eight weeks, experts anticipate these trends persist over time. This is particularly true for patients undergoing prolonged treatment. Continuous research will be essential to validate these findings. It will also improve understanding of how antidepressants interact with individual biology and lifestyle factors.
As the global population continues to grapple with depression and related disorders, this research represents a major step toward personalized mental health care. Now, emotional relief no longer comes at the cost of physical well-being.
