What to Expect During Your First Ketamine Infusion

You've decided to try ketamine therapy. Maybe you've read about the rapid antidepressant effects. Maybe traditional antidepressants failed you. Now comes the nervousness: What actually happens during an infusion? Will I feel strange? Is it safe? Can I drive home? This detailed walkthrough addresses every step—from arriving at Ivie Health to recovering at home—so you know exactly what to expect.

Before Your First Infusion: Pre-Session Preparation

Initial Consultation (Days Before)

Before any ketamine infusion, you'll meet with our clinical team for a comprehensive evaluation. This includes:

• Detailed medical history review (including all medications, supplements, and health conditions)
• Mental health assessment and discussion of your depression, anxiety, or other conditions
• Risk assessment for contraindications (untreated high blood pressure, cardiac issues, substance abuse history)
• Baseline vital signs and possibly blood work
• Review of infusion procedure, expected sensations, and safety protocols
• Questions answered; your concerns addressed

This visit is crucial. Be honest about your medical history, medications, and any past experiences with dissociative drugs or anesthesia. This information helps our physicians customize your treatment safely.

Day of Infusion: What to Do

Arrival and Setup (0-10 minutes)

When you arrive, our nursing team will:

• Check you in and review consent paperwork
• Take vital signs (blood pressure, heart rate, temperature, oxygen levels)
• Assess your current mood and any anxiety or concerns
• Answer final questions before beginning
• Place you in a comfortable reclining chair in a calm, private infusion room
• Establish an IV line in your arm (typically the inside of your elbow)

The IV placement is standard—the same brief pinch you'd feel at any medical appointment. Our nurses are experienced and efficient. Once the IV is secure, you're ready to begin.

The Infusion Experience (10-50 minutes)

Initial Minutes (10-15 minutes)

The ketamine infusion begins slowly. Our clinical team carefully monitors you, checking vital signs regularly. You'll remain alert and aware—you're not being put to sleep. The ketamine is dosed gradually, allowing your body to adjust.

Most people don't feel much initially. You might feel a slight heaviness or slight detachment beginning.

The Dissociative Phase (15-30 minutes)

As the ketamine reaches effective levels, dissociation begins. This is the most significant sensation and deserves careful explanation.

What is dissociation? It's a state where your consciousness feels separated from your body. Common descriptions include:

• "Floating or drifting"
• "Like I'm watching myself from above or outside my body"
• "Dreamlike or in a trance"
• "Time feels distorted or strange"
• "Colors are vivid; sounds feel distant"
• "Limbs feel heavy or tingly"

For some people, dissociation is pleasant—like a peaceful escape. For others, it's mildly uncomfortable. Neither response predicts treatment success; both are normal. The key is that you remain in control. You can speak if needed; our team is immediately present.

Monitoring During Infusion

Throughout the infusion, our clinical team monitors:

• Blood pressure, heart rate, and oxygen saturation (continuous)
• Your verbal and non-verbal responses
• Dissociation level (assessing your comfort)
• Any adverse reactions or discomfort

If you experience any distress—anxiety, physical discomfort, overwhelming sensations—communicate immediately. Our team can slow the infusion, adjust dosing, or provide support to ease you through.

Peak and Resolution (30-45 minutes)

Dissociation typically peaks around the 25-30-minute mark, then gradually diminishes. As the infusion concludes, you become increasingly alert and grounded. Within minutes of the infusion ending, dissociation fades completely.

By 50 minutes post-start, most people are fully back to baseline consciousness. The entire experience—from dissociation onset to complete resolution—typically lasts 45-60 minutes.

Post-Infusion Recovery (Recovery Period)

Immediate Post-Infusion (First 15-20 minutes)

After the ketamine infusion ends, you'll remain reclined in the chair, fully monitored. Our team will:

• Continue monitoring vital signs until completely stable
• Offer water, juice, or snacks
• Assess how you're feeling physically and emotionally
• Discuss any sensations or experiences during the infusion
• Remind you of recovery precautions (no driving, important decisions, etc.)

Many people report feeling remarkably clear and present immediately after the infusion. Some feel tired and prefer to rest quietly. Both responses are fine.

Extended Recovery (15-60 minutes)

You'll remain at our facility in a recovery room for at least 30-45 minutes post-infusion. We want to ensure you're fully grounded and safe before discharge.

During this time:

• You can rest quietly, read, or listen to music
• We'll continue checking on you periodically
• You cannot operate vehicles or machinery
• Coordination and judgment may still be slightly affected

Discharge and Going Home

Before you leave, our clinical team will confirm:

• All vital signs are stable and normal
• You feel safe and oriented
• Your designated driver is present
• You understand post-infusion precautions

You will NOT be allowed to drive yourself home, even if you feel good. This is a strict safety requirement, not optional. Judgment and coordination can be subtly impaired even when you subjectively feel fine. Your designated driver should meet you at our facility.

After You Get Home: Rest and Recovery

Same-Day (First 24 Hours)

Physical Activity: Avoid strenuous exercise, heavy lifting, or physically demanding tasks. Light activity (walking, gentle stretching) is fine. Most people can resume normal activities by evening, but listen to your body.

Driving: Do not drive for at least 24 hours after your infusion. Your reaction time and judgment may still be slightly impaired.

Decision Making: Avoid making major decisions or signing contracts for 24 hours. Your judgment and impulse control can be subtly affected.

Alcohol and Sedatives: Absolutely avoid alcohol, cannabis, and sedative medications for 24 hours. Combined with ketamine remnants in your system, these increase risk of oversedation or poor judgment.

Hydration and Nutrition: Drink plenty of water and eat normal meals. Many people feel thirsty after infusion; this is normal.

Sleep: Some people feel energized post-infusion; others feel tired. Follow your body's natural inclination. Both are normal.

Mental/Emotional Response

Many people report emotional clarity within hours of their first infusion. Depressive thoughts feel less true. Anxiety feels more manageable. Motivation might return. However, don't expect dramatic changes after a single infusion.

The real benefit typically emerges over the first 24-48 hours and deepens with subsequent infusions. Your clinical team will schedule a follow-up phone call to assess how you're responding.

Possible Side Effects and What's Normal

During Infusion

• Dissociation: Universal; expected; passes completely
• Mild Dizziness: Common; resolves quickly
• Slight Nausea: Rare but possible; our team can address immediately
• Tingling or Heaviness in Limbs: Normal dissociation-related sensation
• Increased Heart Rate: Minor elevation is normal; monitored continuously

Post-Infusion (First Few Hours)

• Mild Headache: Occasional; mild; resolves with hydration
• Fatigue: Some people feel tired the evening after infusion; normal
• Slight Dizziness Upon Standing: Rare; avoid rapid position changes
• Emotional Sensitivity: Some people feel emotionally open post-infusion

Serious side effects are rare in therapeutic ketamine administration. However, contact our office immediately if you experience chest pain, severe headache, uncontrolled blood pressure, or concerning mental changes.
