Understanding SSRIs: How Serotonin Reuptake Inhibitors Work

A serotonin reuptake inhibitor (SSRI) is a medication that increases the level of serotonin in the brain. Serotonin is a neurotransmitter that is involved in mood regulation, appetite, sleep, and other functions. SSRIs work by blocking the reuptake of serotonin in the brain, which allows for more serotonin to be available.

SSRIs are used to treat a variety of mental health conditions, including:

* Depression

* Anxiety

* Obsessive-compulsive disorder (OCD)

* Post-traumatic stress disorder (PTSD)

* Premenstrual dysphoric disorder (PMDD)

* Social anxiety disorder

SSRIs are generally well-tolerated, with common side effects including:

* Nausea

* Diarrhea

* Headache

* Dizziness

* Insomnia

* Sexual dysfunction

SSRIs can interact with other medications, so it is important to talk to your doctor about all of the medications you are taking before starting an SSRI.
