The most common thing patients tell me before a first infusion is that they don't know what they're walking into. The internet is full of dramatic trip reports and not much plain description of an actual clinical session. So here's the ordinary version, start to finish, the way it really goes for most people who come through our clinic.
Before you arrive
We ask you not to eat for a few hours beforehand and to arrange a ride home, since you won't be driving afterward. Come in comfortable clothes. If music helps you settle, bring headphones and a playlist, or use ours. Most people are a little nervous on the first visit, which is completely normal. Nerves don't change anything about whether the treatment works.
The intake conversation
Every session starts with a check-in, not the IV. We go over how you slept, what you ate, your mood that day, any medication changes, and how the previous session landed if this isn't your first. We take your blood pressure and baseline vitals. This conversation isn't a formality. If your blood pressure is high, we wait. If you're especially anxious, we slow things down. What we learn here shapes the dose, which is why we do it every single time rather than running a fixed protocol.
Starting the infusion
We place a small IV, usually in the arm or hand, and begin the ketamine as a slow, controlled drip. You stay reclined in a quiet, dimly lit room the whole time. Within a few minutes you'll start to feel the effects. People describe it differently. A floating or weightless feeling, a pleasant heaviness, colors or sounds feeling softer, a sense of gentle distance from the usual mental chatter. This is the dissociative window, and it's where much of the therapeutic shift is thought to happen. It can feel unusual, but it isn't painful, and it doesn't last long.
What we're doing while you rest
Throughout the infusion we monitor your heart rate, blood pressure, and oxygen continuously, and a provider stays present. If anything drifts, we adjust. Most sessions are smooth and uneventful from our side, which is exactly what we want. You don't have to perform or process anything out loud. Your only job is to let the medication work. Some patients close their eyes and turn inward. Others just rest. Both are fine.
You don't have to do the session right. The calm room, the slow drip, and someone watching the numbers are doing the work with you.
The half hour after
When the drip ends, the strongest effects fade within a few minutes, and we keep you for another fifteen to twenty minutes while you come back to baseline. We talk if you want to talk. If you don't, we don't. A physician associate checks in on how you tolerated it and what you noticed, and we make a note of anything worth adjusting next time. Most people feel a little tired and a little tender, in the way you do after something that mattered. That usually settles by evening.
Why the quiet half hour matters
People sometimes assume the recovery time at the end is just a formality, a chance for the medication to wear off before they drive. It's more than that. The minutes right after an infusion are when the nervous system is resettling, and a calm landing helps the experience consolidate instead of feeling jarring. We keep the lights low and the pace slow on purpose. There's no rush to get you talking, walking, or out the door. A session that ends gently tends to leave people feeling steadier that evening than one that ends abruptly, which is reason enough to protect that window.
Common questions about that first session
A few come up almost every time. Will I lose control? No. You stay awake and aware, and you can speak to us the whole time. The dissociative feeling is more like a gentle distance than a blackout, and it lifts within minutes of the drip ending. Will it hurt? Beyond the small pinch of the IV, no. Most people find the session itself physically easy. What if I don't like the feeling? That happens occasionally, and it's why we start slowly and stay in the room. We can ease the pace, and the effect is short-lived regardless. Will I remember it? Usually yes, though the memory can feel soft around the edges, the way a vivid daydream does.
Going home, and the days after
You'll head home with your ride and take the rest of the day easy. The interesting part is that the session itself is only half of the treatment. The days afterward, when sleep and appetite and small motivations start to shift, are where a lot of the real change shows up. We'll talk with you about what to watch for, and if you're working with a therapist we'll coordinate the integration side with them. Most people find the second and third sessions easier than the first, simply because the unknown is gone and they know what the rhythm feels like.
A first infusion is genuinely a small thing to experience and a meaningful thing to have done. If you still have questions, that's the point of the consultation, and you can book one here before deciding anything. Ketamine for mood conditions is used off-label in the United States, and we'll go over what that means for you in plain terms.
