The neurotransmitter serotonin helps regulate mood, emotions and anxiety. Low serotonin levels have been linked to increased feelings of fear & panic due to its effect on how the brain processes information related to stressful situations. Selective Serotonin Reuptake Inhibitors (SSRIs), prescribed medication, are used to treat anxiety or depression by increasing the serotonin level in the brain.

They are ideal for people who want quick relief, but don’t want to take too many risks. SSRIs are also effective within a week, though the individual’s response may vary depending on other factors like dosage or length of treatment. They are an excellent first line treatment for anxiety, as they can address the chemical imbalances that cause symptoms rather than just masking them.
