TL;DR
- •A first sublingual ketamine session at Tovani is a structured 1-2 hour experience at home: physician check-in, dosing, the dissociative window, and integration — followed by a quiet evening.
- •The dissociative effect typically peaks 30-45 minutes after the dose and resolves over 60-90 minutes. By bedtime, most patients are essentially back to baseline cognitively.
- •You'll be supervised remotely by your physician via video for the dosing phase. A trusted adult should be in the home during the session — not necessarily in the room, but available.
- •Preparation matters: light eating before, water available, comfortable familiar environment, headphones with prepared music, no driving or major decisions for 24 hours.
- •The mood response can be visible the same day — many patients describe "feeling lighter" within hours of the first session, though full response typically develops over the first 2-3 sessions.
- •The next morning, most patients return to normal activity. You're not impaired the day after; the dissociative effect doesn't persist.
Step by step
- 1
The hour before — preparation
Eat a light meal 2+ hours before to reduce the chance of nausea. Set up your space — quiet, dim, comfortable, with water nearby. Have your prepared music ready (Tovani provides curated playlists; many patients use their own). Make sure someone you trust is in the home for the session, even if not in the room with you.
- 2
Physician check-in (15 minutes)
Your physician joins via video for a brief check-in: how you've been since the last consultation, any medication changes, current intentions for the session, any specific concerns. This is your moment to mention anything unusual — sleep, mood shifts, recent stressors. The physician confirms the dose and the plan.
- 3
Dosing (5 minutes)
Place the prescribed ketamine lozenge under your tongue. Hold without swallowing for 10-15 minutes — the medication absorbs through the oral mucosa. After the hold time, you can swallow what's left. Most patients describe the lozenge as slightly bitter; some patients pre-rinse with a flavored beverage to mute the taste.
- 4
Onset and dissociation (30-90 minutes)
Effects begin within 15-20 minutes — typically a softening of body sensations, gentle visual changes (colors more saturated, mild geometric patterns with eyes closed), a sense of distance from immediate worries. The peak lands around 30-45 minutes after dosing. Most patients describe it as gentle and curious rather than intense. The eyemask + music creates an interior experience.
- 5
Recovery (60-90 minutes)
The dissociative effect fades gradually. You'll be able to talk, walk to the bathroom, drink water — but you're not at full operating capacity. Stay in the comfortable space. Many patients journal during this phase to capture insights or impressions while they're fresh.
- 6
Integration (15-30 minutes)
A brief video check-in with your physician or care team to discuss the experience: what felt notable, any concerns, plan for the rest of the day. This is also when you can flag if something felt unusual so the next session can adjust.
- 7
The rest of the day and night
No driving, no important decisions, no alcohol for 24 hours. A quiet evening is ideal — most patients describe feeling reflective and gentle rather than activated. Sleep is typically deep. Vivid dreams are common the night of and following nights.
What this actually feels like
Sublingual ketamine at therapeutic doses produces a gentle altered-perception state, not a dramatic psychedelic trip. Most patients describe: a soft warmth or floating sensation, gentle visual changes (colors more vivid, geometric patterns with closed eyes), distance from immediate concerns, sometimes profound feelings of compassion or connection, and a sense that one's usual mental patterns are temporarily suspended. The body feels heavy or weightless; some patients have a sense of being "outside" themselves looking in. Words can become less reliable — many patients prefer not to talk during the experience. The dissociation is curious and gentle rather than frightening for most patients, especially with good preparation. Music plays a major role; many patients describe the music feeling like a guide through the experience.
Timeline
First-session response varies. Some patients feel a clear mood shift within hours of the first session — "lighter," "less heavy," "the depression is quieter." Others see initial response after the second or third session. Full response typically develops over the first 2-3 weeks (3-6 sessions). The session itself is 1-2 hours; the medication effect resolves by bedtime; the next morning you're cognitively normal. Patients often describe the days following the first session as a "honeymoon" period — sometimes the response lasts only 3-7 days at first, building duration with subsequent sessions.
Common concerns, addressed
“I'm worried I'll lose control or have a bad trip”
Sublingual ketamine at therapeutic doses doesn't produce the intensity of recreational doses. The dissociative effect is gentle and time-limited (60-90 minutes). Patients remain aware of their surroundings; you can stop, stand up, drink water, ask for help. The combination of clinical dose, eye mask, prepared music, and supportive environment produces a contained experience.
“Will I be addicted to ketamine after this?”
Therapeutic sublingual ketamine in supervised settings has very low addiction risk per published evidence. The episodic dosing (sessions over weeks, then monthly maintenance) is structurally different from the chronic-daily use that drives addiction. Tovani screens for substance-use risk during eligibility consultation.
“What if I cry / panic / have a difficult experience?”
Difficult emotions can surface during sessions — that's sometimes part of the therapeutic effect rather than something going wrong. Your care team is reachable during the session if you need support. Most patients describe difficult moments as meaningful in retrospect, not damaging. The integration check-in afterward addresses anything that came up.
“I don't want to talk during the session”
Good. Most patients don't. The session is interior — eye mask, music, headphones. Your physician checks in before and after but doesn't direct the experience during dosing. Words often feel unreliable during the peak.
“What if I have nausea?”
Common but manageable. Light eating 2+ hours before reduces the chance significantly. If nausea occurs, anti-nausea medications can be added to the protocol for future sessions. Some patients use ginger or peppermint preparations.
Who this fits best
Sublingual ketamine therapy works best for patients who: (1) have treatment-resistant depression, anxiety, or PTSD that has not responded sufficiently to SSRIs/SNRIs and/or therapy; (2) are comfortable with at-home telehealth treatment; (3) can arrange the supportive environment (someone in the home, quiet space) for sessions; (4) don't have specific contraindications (uncontrolled hypertension, severe cardiovascular disease, active substance use disorder, active psychotic disorder, pregnancy/breastfeeding). For patients with significant trauma history or prior pathological dissociation, additional clinical screening and possibly slower initial protocols are appropriate.

Frequently asked
Do I need someone with me during the session?
A trusted adult should be in the home — not necessarily in the room with you, but available. They're there for unlikely emergencies and to help during recovery (water, walking around, etc.). Many patients have a partner or friend present in another room with their door open.
Will I feel like myself the next day?
Yes. The dissociative effect resolves by bedtime; the next morning you're cognitively normal and back to your usual activities. Most patients describe the day after as similar to a day after a deep meditation or therapy session — reflective and gentle rather than altered.
How quickly does it work?
Some patients notice mood improvement within hours of the first session ("lighter," "less heavy"). Others see clear response after the second or third session. Full response typically develops over the first 2-3 weeks (3-6 sessions). The mechanism (rapid antidepressant effect via NMDA/glutamate) is fundamentally faster than SSRIs (4-6 weeks).
What if I don't feel anything?
Not feeling anything during the first session doesn't mean treatment is failing. Some patients have a delayed response; others have a subtle response that builds with subsequent sessions. Dose adjustment, environmental optimization (music, eye mask, supportive environment), and patience over the first 2-3 sessions usually produce response. Discuss with your physician if you're not seeing change by session 4-5.
Should I journal during or after?
Many patients find journaling immediately after the session (during the recovery phase) helps capture insights or impressions that fade quickly. Brief notes are usually more useful than detailed accounts. During the session itself, words are often unreliable — most patients prefer to stay inside the experience and journal afterward.
