Paxil (Paroxetine): A Complete Guide

Paxil (paroxetine) is one of the most commonly prescribed SSRIs for anxiety and depression. At Next Step Psychiatry in Lilburn, we help patients understand their medication options and find what works best for their needs.

What Is Paxil?

Paxil is a selective serotonin reuptake inhibitor (SSRI) that works by increasing serotonin availability in your brain. It comes in regular and extended-release (Paxil CR) formulations.

• Major depressive disorder
• Generalized anxiety disorder
• Social anxiety disorder
• Panic disorder
• PTSD
• OCD
• PMDD

How Long Until It Works?

You may start noticing improvement within 2-6 weeks, though full effects can take longer. Don't stop taking it if you don't see immediate results—give it time.

Common Side Effects

• Nausea, constipation, diarrhea
• Drowsiness or insomnia
• Dry mouth
• Sexual side effects
• Weight changes
• Sweating

Most side effects are temporary and improve as your body adjusts.

Important Considerations

• Paxil has a relatively short half-life, making missed doses more noticeable
• Stopping suddenly can cause withdrawal symptoms—always taper with your doctor's guidance
• Inform your doctor about all other medications and supplements
