Depression and anxiety are among the most common mental health conditions in the world. They can affect how people think, feel, sleep, work, and interact with others.
For many people, antidepressant medications can make a major difference, helping them regain energy, improve their mood, and return to daily activities. However, one of the biggest challenges with antidepressant treatment is dealing with side effects.
Many people stop taking antidepressants within the first few months of treatment. In some cases, this happens because the medication does not provide enough benefit. In many other cases, people stop because the side effects are unpleasant or difficult to manage.
For this reason, researchers have spent years trying to understand which antidepressants are easiest for people to tolerate and which ones patients are most likely to continue taking.
Today, doctors have many antidepressant options available. These medicines work by affecting chemicals in the brain that help regulate mood, emotions, motivation, and sleep.
The most commonly prescribed groups include selective serotonin reuptake inhibitors, often called SSRIs, serotonin-norepinephrine reuptake inhibitors, known as SNRIs, and several newer medications that work in different ways.
Older antidepressants, such as tricyclic antidepressants and monoamine oxidase inhibitors, are still used in some situations but are generally prescribed less often than they were in the past.
One of the most important studies comparing antidepressants was published in The Lancet in 2018. The research team analyzed information from more than 500 clinical trials involving over 100,000 participants. The goal was to compare how well different antidepressants worked and how often people stopped taking them because of side effects.
The results showed that several medications stood out for their good balance between effectiveness and tolerability. Among the best-performing options were escitalopram, sertraline, and agomelatine. People taking these medications were generally less likely to stop treatment because of side effects compared with many other antidepressants.
Escitalopram, sold under the brand name Lexapro in some countries, belongs to the SSRI family. It is widely prescribed for depression and anxiety disorders. Many doctors consider it one of the easier antidepressants to tolerate.
Common side effects may include mild nausea, headaches, sleep changes, or stomach discomfort. For many patients, these problems improve after the first few weeks as the body adjusts to the medication. Escitalopram is often chosen because it tends to have a relatively low risk of causing severe side effects.
Sertraline, commonly known by the brand name Zoloft, is another SSRI that has been used for many years. It is prescribed for depression, anxiety disorders, panic disorder, obsessive-compulsive disorder, and several other conditions. Like escitalopram, sertraline is generally well tolerated.
Some people experience digestive problems, headaches, or sleep disturbances during the early stages of treatment, but many find these effects become less noticeable over time.
A newer antidepressant called agomelatine works differently from SSRIs. Instead of mainly affecting serotonin, it influences melatonin and norepinephrine pathways in the brain. This unique action may help improve both mood and sleep.
One reason agomelatine has attracted attention is that it appears less likely to cause sexual side effects or weight gain, two concerns that often lead people to stop antidepressant treatment. However, doctors usually monitor liver function in people taking agomelatine because the medication can affect the liver in some cases.
Another medication that is often praised for its tolerability is bupropion, known by the brand name Wellbutrin. Bupropion works on dopamine and norepinephrine rather than serotonin. Many patients appreciate that it is less likely to cause sexual side effects compared with many SSRIs.
Some people also report improved energy levels and better concentration while taking it. In addition to treating depression, bupropion is also used to help people stop smoking. However, it is not perfect for everyone. Some individuals may experience anxiety, restlessness, or difficulty sleeping, especially when starting treatment or taking higher doses.
Older antidepressants remain important treatment options, but they often come with a higher burden of side effects. Tricyclic antidepressants, such as amitriptyline, can cause dry mouth, dizziness, constipation, blurred vision, and weight gain.
Monoamine oxidase inhibitors can interact with certain foods and medications, requiring people to follow special dietary rules. Because of these challenges, doctors usually reserve these medications for situations where newer treatments have not worked.
It is important to understand that antidepressants affect people differently. A medication that works extremely well for one person may cause troublesome side effects in another.
Factors such as age, genetics, medical history, other medications, and personal sensitivity can all influence how someone responds. Finding the right antidepressant sometimes requires patience and close communication with a healthcare provider.
Doctors often start treatment with a lower dose and gradually increase it if needed. This approach can help reduce side effects and give the body time to adjust. Patients are also encouraged not to stop antidepressants suddenly without medical advice, as doing so can lead to withdrawal symptoms or a return of depression or anxiety symptoms.
Overall, research suggests that escitalopram, sertraline, agomelatine, and bupropion are among the antidepressants that many people tolerate well. They tend to cause fewer troublesome side effects and are associated with higher treatment continuation rates than many alternatives.
However, the best antidepressant is always the one that works safely and effectively for the individual patient. With the support of a doctor or mental health professional, people can find a treatment plan that helps them manage their symptoms and improve their quality of life.
