At-home ketamine is the version of this treatment most people end up actually doing. Less because it’s better than the IV in a clinic, and more because it costs less, fits around real life, and meets a lot of patients where they already are, which is on their couch at 7 PM with the dog and a weighted blanket.
The model is straightforward. A clinician evaluates you over telehealth, decides you’re a reasonable candidate, and writes for a compounded sublingual troche or rapid-dissolve tablet that’s mailed to you. You take it at home on a defined schedule, usually twice a week for the first month, then less often. Most programs land somewhere between 50 and 200mg per dose, titrated up from a low test dose. That’s a fraction of what you’d get IV, and the experience is different too. More dreamy, less out-of-body. People describe it as a long warm float with vivid imagery, nothing like the full ego-dissolution of a clinic infusion.
There are two pretty different versions of this in the wild and they’re worth telling apart. There’s the high-volume telehealth-only model (Mindbloom, Joyous, Better U, a dozen others). And there’s the at-home protocol prescribed by a clinician you actually know, often as a maintenance step after an in-clinic series. Both are technically “at-home ketamine.” They are not the same product.
What the dose actually feels like
Sublingual ketamine peaks roughly 20 to 40 minutes after you tuck the troche under your tongue and hold it there. You swish the saliva, you don’t swallow until the timer goes off, you spit or swallow the residue depending on what your prescriber tells you. Bioavailability sublingually is around 25 to 30 percent, which is why the oral doses look big compared to IV.
At 50mg you’ll feel a mild warmth, some visual softening, music gets interesting. At 100 to 150mg, which is where a lot of programs settle, you’ll get the dreamy state. Body feels heavy or floaty. Time stretches. Internal imagery shows up if you close your eyes. You can usually still get up and walk to the bathroom, though you shouldn’t, because your coordination is off and you’ll feel like you’re walking on a boat. At 200mg and above you’re in territory where dissociation is real and you should not be moving around.
Most people find it interesting, sometimes uncomfortable, occasionally beautiful. Recreational it is not. Nausea is the most common annoying side effect, which is why most compounded formulations include ondansetron or are taken with a Zofran an hour before. Blood pressure goes up a bit. Heart rate goes up a bit. If you have uncontrolled hypertension or a history of psychosis, you shouldn’t be doing this at home.
The protocol that keeps people safe
A reasonable at-home ketamine protocol looks roughly like this. Quiet room. Eye mask. A playlist you’ve heard before so it doesn’t surprise you. A support person physically in the house, not on FaceTime, who knows what you took and isn’t going to freak out if you say something weird at minute 35. Phone on do-not-disturb. No driving for the rest of the day. No alcohol. No benzos within a few hours either side. Journal nearby for after, not during.
The integration session is the part most people skip and most people shouldn’t. It’s a telehealth call, usually the day after or two days after, where you talk through what came up. The good prescribers don’t ask if you had a cool trip. They ask what you noticed about how you talk to yourself, what came up about your marriage, what felt different the next morning. The drug opens a window. The integration is what turns the window into actual change. Without it, people get a pleasant Tuesday afternoon and not much else.

Where the telehealth-only model gets sketchy
I’ll be direct about this part. The screening at some of the big telehealth-only ketamine companies is, in clinical terms, thin. A 20-minute intake, a checkbox form, and you’re approved. I’ve had patients come to me after starting one of these programs who never had their blood pressure checked, never had a real conversation about their substance use history, never got asked about dissociative symptoms or trauma, and were on doses that escalated faster than I’d be comfortable writing.
I had a guy last spring, late 20s, who’d been on one of the daily low-dose platforms for about five months. He came in for what he thought was an ADHD evaluation. By the time we’d been talking for ten minutes it was obvious the ketamine had become the thing organizing his day. He took the troche before bed, and if the package was late from the compounding pharmacy he had a bad week. He’d stopped seeing his therapist because the ketamine “did more anyway.” He was still depressed. He was now also dependent on a drug nobody had ever sat with him about, and the platform’s response to his check-in form was to offer him a slightly higher dose.
That’s the failure mode. The drug isn’t especially dangerous at these doses on its own. The at-home telehealth model is just structurally bad at noticing when somebody is using ketamine to dodge instead of using it to move. The safety nets aren’t there. A clinic-based program has a nurse who sees your face, takes your vitals, notices the third week in a row you’ve gotten worse. A subscription model has a refill button.
Who at-home actually fits
TRD, stable life
Treatment-resistant depression, failed two or more SSRIs, no active substance use, no psychosis history, a person at home who’s sober and reachable, working with a therapist already.
Anxiety only, alone
Anxiety without depression responds less well. Living alone means no support person, which matters more than people think. Possible, but the bar for screening should be higher.
Active addiction, psychosis
Active alcohol or stimulant use, history of psychosis or mania, uncontrolled hypertension, pregnancy, recent ketamine abuse. These need in-person care or a different medication entirely.
The patients who do best with at-home ketamine usually share a few things. They’ve already tried the obvious meds and gotten partial responses. They have somebody in the house. They have an outpatient therapist they’re already working with, so the integration doesn’t fall into a void. They take the protocol seriously, which means they don’t try to multitask through the dosing session and they don’t drink afterward.
The patients who don’t do well are the ones using it as a fix instead of a tool. The ones who skip the integration calls. The ones who escalate dose on their own. The ones using it to feel less, rather than to feel different.
What I tell people who ask
If you’ve done two or three antidepressant trials, you’re still depressed, you’ve got a therapist, and you’re stable enough to follow a protocol, at-home ketamine is a reasonable next step. Cheaper than IV, lower acuity, fits around a job. Go in with a real prescriber, not just a platform. Ask them how they screen. Ask them what the integration looks like. Ask them what happens if it’s not working at week six.
If you’re shopping for a subscription that mails you troches indefinitely with no clinical contact between refills, that’s not psychiatric care. It’s a vending machine with a doctor’s signature stapled on. The drug might still help. Or it might quietly become the new thing you can’t function without. The structure around the dosing is doing as much work as the dose.
The patients I’ve seen genuinely turn around on this protocol all had the same thing in common, which wasn’t the dose or the platform. They had somebody asking real questions the morning after, and they had someplace concrete to put what came up. Take that piece away and you’ve got a moderately interesting evening on a couch. Keep it, and the drug starts doing what it was supposed to do in the first place.
