- They work by balancing chemicals in the brain that affect mood, sleep, and emotional well-being.
- Often prescribed for long-term use to prevent relapses and manage symptoms effectively.
How Do Antidepressants Work?
- Alter the levels of neurotransmitters such as serotonin, norepinephrine, and dopamine in the brain.
- Promote better communication between brain cells to improve mood and emotional stability.
- Effects typically become noticeable after 2-4 weeks of consistent use.
Types of Antidepressants
1. Selective Serotonin Reuptake Inhibitors (SSRIs)

- Examples: Sertraline (Zoloft), Escitalopram (Lexapro), Fluoxetine (Prozac).
- Uses: Depression, anxiety disorders, OCD, PTSD.
- Common Side Effects: Nausea, insomnia, sexual dysfunction.
2. Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs)

- Uses: Major depressive disorder (MDD), anxiety, chronic pain (e.g., fibromyalgia).
- Common Side Effects: Dry mouth, fatigue, dizziness.
3. Tricyclic Antidepressants (TCAs)
- How They Work: Increase serotonin and norepinephrine by blocking their reuptake.
- Examples: Amitriptyline, Imipramine (Tofranil).
- Uses: Depression, chronic pain, insomnia.
- Common Side Effects: Weight gain, drowsiness, dry mouth.
4. Monoamine Oxidase Inhibitors (MAOIs)
- How They Work: Prevent the breakdown of serotonin, norepinephrine, and dopamine by inhibiting monoamine oxidase enzymes.
- Examples: Phenelzine (Nardil), Tranylcypromine (Parnate).
- Uses: Severe depression unresponsive to other treatments.
- Common Side Effects: High blood pressure with certain foods, dizziness.
