Selective Serotonin Reuptake Inhibitors (SSRIs).. Fluoxetine (Prozac). Sertraline (Zoloft). Escitalopram (Lexapro). Citalopram (Celexa). Paroxetine (Paxil)

What are Selective Serotonin Reuptake Inhibitors (SSRIs)?

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly prescribed type of antidepressant medication. They work by increasing the levels of serotonin in the brain, a neurotransmitter that plays a crucial role in mood regulation.

How do SSRIs work?

When you experience a pleasurable event, your brain releases serotonin, creating feelings of happiness and well-being. In individuals with depression, the level of available serotonin is often reduced. SSRIs work by blocking the reuptake of serotonin by nerve cells in the brain. This allows more serotonin to remain available in the synapses, potentially improving mood and reducing symptoms of depression.

Common SSRIs:

  • Fluoxetine (Prozac).
  • Sertraline (Zoloft).
  • Escitalopram (Lexapro).
  • Citalopram (Celexa).
  • Paroxetine (Paxil).

Benefits of SSRIs:

  • Effective treatment for depression: Studies have shown SSRIs to be significantly more effective than a placebo in reducing symptoms of depression.
  • Relatively well-tolerated: SSRIs generally have fewer side effects compared to other types of antidepressants, such as tricyclic antidepressants (TCAs).
  • Safer than older medications: SSRIs are considered safer than older antidepressant medications like MAOIs (monoamine oxidase inhibitors) due to fewer potential interactions with other medications and foods.

Side effects of SSRIs:

Like all medications, SSRIs can cause side effects, although not everyone experiences them. Some common side effects include:
  • Nausea.
  • Dry mouth.
  • Sexual dysfunction.
  • Dizziness.
  • Fatigue.
  • Insomnia or sleepiness.
  • Headache.

Important considerations:

  • SSRIs are not a cure for depression, but rather a treatment to manage symptoms and improve quality of life.
  • It may take several weeks (4-6 weeks on average) to feel the full effects of an SSRI.
  • Do not stop taking your medication abruptly without consulting your doctor, as this can cause withdrawal symptoms.
  • It is essential to be honest with your doctor about your medical history and any medications you are taking to ensure SSRIs are safe and appropriate for you.
  • SSRIs may not be suitable for everyone, and alternative medications or treatment options might be considered.
