No Testing, Just Trial and Error

Antidepressants like SSRIs and SNRIs alter serotonin levels in the brain—but patients are rarely tested for serotonin levels before treatment begins. Without any objective measure, doctors rely on symptoms alone, risking serotonin overload and emotional side effects.

Symptoms of Serotonin Excess

• Emotional flatness or numbness
• Sexual dysfunction or loss of desire
• Disconnection from relationships
• Brain fog and loss of motivation
• Increased anxiety or restlessness

These signs are often misdiagnosed as a return of depression rather than side effects of too much serotonin.

Why Aren’t Serotonin Levels Measured?

There is no standard test to measure brain serotonin. Most of the body’s serotonin exists in the gut, not the brain. Without reliable testing, antidepressant dosing becomes a guessing game—with life altering consequences for patients.

Time for a New Conversation

If your loved one feels distant or emotionally shut down after starting medication, don’t ignore it. They may be experiencing serotonin excess—something most people aren’t warned about. It’s time we start asking better questions and demanding safer, more personalized care.
