Several kinds of antidepressants are available in the market but you must take the one which is suggested by your doctor or healthcare provider to ensure effective results.

Selective Serotonin Reuptake Inhibitors (SSRIs)

These are widely prescribed antidepressants.

These types of antidepressants come with fewer side effects than others.

Fluoxetine (Prozac) is a good example of an SSRI in addition to citalopram and paroxetine.

Serotonin-Noradrenaline Reuptake Inhibitors (SNRIs)

They are similar to SSRIs and are effective to treat depression issues.

They are also suggested to treat anxiety issues and chronic pain.

Duloxetine and venlafaxine are good examples of SNRIs.

Noradrenaline & Specific Serotonergic Antidepressants (NASSAs)

  • They are suggested for people who cannot take SSRIs.
  • These psychiatric drugs enhance the effectiveness of neurotransmitters in the brain that are responsible for mood regulation.
  • Mirtazapine and aptazapine are examples of NASSAs.

Tricyclic Antidepressants (TCAs)

  • They are old-type antidepressants.
  • These types of antidepressants are not recommended as the first-time treatment of depression due to the dangers associated with overdose.
  • TCAs have more side effects in comparison with SSRIs and SNRIs.
  • They are also suggested to treat other mental health issues such as bipolar disorder and OCD.
  • Clomipramine, amitriptyline, nortriptyline, and imipramine are a few instances of TCAs.

Serotonin Antagonists & Reuptake Inhibitors (SARIs)

  • These antidepressants are also not first-choice medicines to treat depression.
  • SARIs are only suggested when other antidepressants cause side effects or do not work well.
  • Trazodone can be taken as a good example of SARI.

Monoamine Oxidase Inhibitors (MAOIs)

  • They are rarely suggested today.
  • They can cause serious side effects so only specialized doctors can prescribe them.
  • Phenelzine, isocarboxazid, and tranylcypromine are a few MAOIs.
