Anxiety Drugs Selective Serotonin Reuptake Inhibitors (SSRIs)
- Citalopram (Celexa)
- Escitalopram (Lexapro)
- Fluoxetine tablets or capsules (Prozac)
- Fluvoxamine (Luvox)
- Paroxetine (Paxil, Paxil CR, Pexeva)
- Sertraline (Zoloft)
HOW DO THESE DRUGS WORK?
These drugs block the reuptake of serotonin so that it remains active in the brain longer before being broken down and reabsorbed. The neurotransmitter serotonin gives the sensation of well-being.
WHAT ARE THE BENEFITS?
Improvement in depression, generally with fewer side effects than other categories of antidepressants. SSRIs have fewer side effects than the tricyclic antidepressants and monoamine oxidase (MAO) inhibitors, which we discuss below. Unlike MAO inhibitors, SSRIs do not interact with the amino acid tyramine found in certain foods. Also, SSRIs do not cause orthostatic hypotension and heart rhythm disturbances, as tricyclic antidepressants can. SSRIs are often the first-line pharmaceutical choice for depression.
POTENTIAL SIDE EFFECTS
- Nausea
- Diarrhea
- Agitation
- Insomnia
- Decreased sexual desire
- Delayed orgasm or inability to have an orgasm
MAJOR CAUTIONS
Tremors can be a side effect of SSRIs. Serotonergic syndrome, in which serotonin levels are too high, is a serious but rare condition associated with the use of SSRIs. Symptoms can include high fevers, seizures, and heart rhythm disturbances. (more…)
