Antidepressants are a broad class of medications used to treat depression, anxiety, and other mental health conditions. They typically work by altering neurotransmitter levels, such as serotonin, norepinephrine, and dopamine.
Key Points:
- Common Classes:
- SSRIs (Selective Serotonin Reuptake Inhibitors): e.g., fluoxetine, sertraline
- SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors): e.g., venlafaxine
- Tricyclic Antidepressants (TCAs): older class, more side effects
- Side Effects: Can include nausea, weight changes, sexual dysfunction, or insomnia.
- Efficacy: Often most effective when combined with psychotherapy. Full benefit may take weeks to appear.
