Antidepressants can reduce depressive symptoms, but do not work the same for everyone. The groups differ in their influence on signal transmission in the brain, side effects, interactions and the ease with which you can stop. 'Newer' or 'stronger' does not automatically mean better.
Below are the most important groups and examples of active substances used in Dutch healthcare. It is not a complete leaflet or selection list to start with yourself. Some drugs are also used for anxiety, compulsion or pain: a prescription for an antidepressant does not always mean that you have depression.
The usual first choice is not the only good choice. If medication is appropriate for an adult, the NHG lists citalopram, escitalopram, fluoxetine and sertraline as preferred drugs. Another drug that previously helped and was well tolerated does not therefore need to be replaced. Discuss the reason for your choice with the prescriber.

SSRIs: often considered first
Examples: citalopram, escitalopram, fluoxetine, sertraline, paroxetine and fluvoxamine.
For what and how? They inhibit the reuptake of serotonin. They are used for depression and, depending on the drug, also for anxiety or obsessive-compulsive disorders. Paroxetine and fluvoxamine are not preferred drugs for a new treatment of depression in the general practice guideline.
NB: nausea, restlessness, changes in sleep and sexual symptoms may occur. With citalopram and escitalopram, the heart rhythm is sometimes an additional point of attention. Paroxetine can be difficult to reduce. Good effect on mood is not the only measure: side effects on sexuality or daily functioning also deserve attention.

SNRIs: serotonin and norepinephrine
Examples: venlafaxine and duloxetine.
For what and how? They influence the reuptake of serotonin and norepinephrine and can be a next step in depression. Both also have applications in certain anxiety disorders. Duloxetine is also used for nerve pain due to diabetes. That doesn't mean it's suitable for every type of pain.
NB: including nausea, sweating, sexual symptoms and increased blood pressure. Blood pressure should be monitored with venlafaxine; liver and kidney problems also count with duloxetine. Especially with venlafaxine, a missed dose or tapering too quickly can cause withdrawal symptoms.

Tricyclic antidepressants (TCAs)
Examples: amitriptyline, nortriptyline, clomipramine, imipramine and dosulepine.
For what and how? These are older antidepressants that affect multiple signaling systems. They can be used for depression if other choices are insufficient or have not helped previously. Some, such as amitriptyline, are also used for nerve pain; Pain treatment is not the same as depression treatment.
NB: dry mouth, constipation, drowsiness, dizziness when standing up and difficulty urinating. Heart rhythm and safety in the event of overdose are also taken into account. The doctor may consider an ECG or blood level check necessary. In general practice, TCAs are not the standard first choice.

Mirtazapine: a different side effect profile
Group: often referred to as NaSSA; influences noradrenergic and serotonergic signals via receptors.
For what? Depression, for example if another choice does not help enough or is not well tolerated. Sleepiness and increased appetite can be taken into account in the choice, but do not automatically make it the best treatment for someone who sleeps poorly or eats little.
NB: drowsiness, dry mouth and weight gain occur. Getting drowsy can happen quickly; that is not the same as recovery from depression. Also discuss the influence on driving, work and combination with alcohol or other narcotics.

Bupropion: norepinephrine and dopamine
Group: reuptake inhibitor of norepinephrine and dopamine, often called NDRI.
For what? A possible next step for depression. A different registration and product name are used when quitting smoking. These applications are not simply interchangeable.
NB: insomnia, restlessness, dry mouth and increased blood pressure may occur. Due to the risk of epileptic seizures, it is unsuitable for epilepsy or a history of anorexia or bulimia. Abruptly stopping a lot of alcohol or benzodiazepines is also an important risk to discuss with the doctor.

Vortioxetine: multiple serotonergic effects
Group: an antidepressant that affects both the reuptake and certain receptors of serotonin.
For what? Depression in adults, usually when other preferred medicines are insufficiently appropriate. It is not automatically a better choice because it works differently.
NB: especially nausea, but also dizziness and gastrointestinal symptoms. Sexual side effects cannot be ruled out. As with other serotonergic agents, the pharmacist must check for dangerous combinations.

Agomelatine: melatonin and serotonin receptors
For what and how? Agomelatine works on melatonin receptors and certain serotonin receptors. It can be considered for depression after inadequate results from a preferred drug. It is not the same as a melatonin supplement or a regular sleep aid.
NB: there is a risk of liver damage. Therefore, blood checks are necessary before and during treatment. It is not suitable for liver disease. Discuss new jaundice, dark urine or unexplained severe fatigue with a doctor immediately.

Trazodone: serotonergic and often sedating
For what and how? Trazodone affects serotonin via receptors and reuptake. It is an antidepressant, but not a preferred drug for a new treatment in general practice. Use for insomnia alone may be off-label: outside the registered use. Then discuss the purpose and substantiation.
NB: drowsiness, dizziness, drop in blood pressure when standing up and cardiac arrhythmias. A rare but urgent side effect is a persistent, painful erection; seek immediate medical attention. A sleep-promoting effect does not prove that depression is being adequately treated.

MAOIs: specialist choices
Examples: tranylcypromine and moclobemide.
For what and how? They inhibit an enzyme that breaks down signaling substances. Tranylcypromine may be an option for depression that does not respond sufficiently to other treatments. Moclobemide is a reversible MAO-A inhibitor, but according to the Kompas it has no place in the Dutch depression guidelines. The properties and precautions differ.
NB: there are important interactions with other medications. Tranylcypromine requires strict, personal dietary advice due to tyramine and the risk of a dangerous increase in blood pressure. Do not use those dietary rules as a general rule for every MAOI. Switching requires a careful plan and sometimes a waiting period between medicines.
Compass: tranylcypromine and moclobemide
Other names: include mianserin
You may also come across older or less commonly used agents, such as mianserin and maprotiline. Classifications vary: some are called tetracyclic or discussed together with related older antidepressants. A group name alone does not say enough about operation or safety.
Mianserin can be used for depression when other medicines do not help enough. Drowsiness and weight gain are areas of concern; Fever, sore throat or blisters in the mouth may indicate rare blood abnormalities and require consultation with the doctor. If the name is unknown, always ask for the active substance, the treatment goal and your own package leaflet.
