The honest answer to “can I stay on this medication for the rest of my life” is: we don’t fully know what happens at 30 or 40 years out, because most of these medications haven’t been around long enough at scale for anyone to have that data. We have decent numbers at 10 to 20 years for some of them. We have basically nothing on the 40-year horizon. Anybody telling you otherwise is making it up.
That’s not a reason to refuse medication, and if anybody reading this is using it that way, that’s not what I’m saying. It’s a reason to think carefully about what we do and don’t know, and to actually ask the question every couple years instead of refilling on autopilot until somebody dies.
What we know at 10 to 20 years
Lithium has the longest track record of any modern psych medication. It’s been in use since the 1950s, which means we’ve watched several generations of patients live their whole adult lives on it. The long-term data is reasonably reassuring for most patients, with one big caveat: you have to monitor kidney function and thyroid function forever, because both can take a hit over the decades. A subset of patients develops chronic kidney disease related to the lithium, and that risk is real, it’s not common, and it’s manageable if anyone is paying attention. The patients who get burned on lithium are usually the ones whose prescriber stopped checking the labs after year five because the patient was stable.
The SSRIs (the serotonin-boosting class, Prozac, Zoloft, Lexapro, Paxil, Celexa) have been around since the late 80s, so the longest real-world cohorts are now hitting 30 years on. The good news is that we haven’t found a major emerging long-term harm. People who’ve been on Prozac since 1990 aren’t, as a population, falling apart from it. The downsides we already know about, the sexual side effects, some weight gain, occasional GI stuff, the withdrawal issues coming off, those are the downsides at year one and they’re also the downsides at year twenty. Nothing new has shown up in the cohort. That’s about as good news as you can get from an observational study of an entire generation of patients.
Antipsychotics are where the long-term picture gets more complicated. Long-term metabolic effects, the weight, the diabetes, the cholesterol going the wrong direction, are very real and they don’t get better with time on the drug. Tardive dyskinesia, a movement disorder where you start having involuntary tics or twitches that can be permanent, accumulates over years of antipsychotic use. The newer “atypical” antipsychotics (Abilify, Risperdal, Seroquel, Zyprexa, the ones developed after the 80s) are less likely to cause it than the older Haldol-era drugs, but the risk isn’t zero. If you’ve been on an antipsychotic for 15 years, you should be getting screened for the movement disorder regularly. Most people on long-term antipsychotics aren’t. That’s a problem.
Stimulants for ADHD (Adderall, Vyvanse, the amphetamine class, plus methylphenidate, Concerta, Ritalin) we have decent data on for adult use over the last 20 years. The big concerns at long-term scale are cardiovascular, mostly blood pressure creeping up, and sleep slowly getting worse, both of which are manageable if anyone’s tracking them. The “they rot your brain” panic that occasionally cycles through the media has not been borne out by the data. They’re stimulants. Used at therapeutic doses with monitoring, they’re broadly safe in adults over decades, and probably one of the better-tolerated long-term medication classes if your case actually needs them.
The reassessment question
The default in most psychiatry practices is that once you’re stable on a medication, refills happen indefinitely without much reassessment. That’s the actual problem here. It’s not necessarily wrong to stay on a medication for decades. It IS wrong to stay on it for decades without anyone ever asking whether it’s still doing what you started it for, or whether the original problem has resolved, or whether the trade-offs you accepted at age 32 still make sense at age 57.
There are guys on lithium for 25 years who still need it. Their bipolar isn’t subtle and the medication is what keeps the wheels on. There are also guys who got started on an antidepressant during a divorce in their 30s, are now in their 50s, life looks completely different, the wife is a memory, the job is a memory, and nobody has ever asked whether the medication is still doing something or whether momentum has been driving the refills for fifteen years. Those guys might be fine off it. Or they might come off and find out at year one that they’re not. The point isn’t that they need to taper, the point is that nobody has had the conversation, and that’s just lazy.
The cadence I use
For mood disorders, the reassessment question gets revisited every year or two for stable patients. Not because they need to come off, but because the question deserves to be asked. The conversation is: how are you doing actually, what would your life realistically look like off this medication, are we still treating the original problem or are we treating something else that drifted in over the years.
For ADHD stimulants, the check is more practical. How’s the tolerance doing, is the medication still working at the dose it was, how’s the sleep, what’s the blood pressure looking like, any mood drift. Stimulants get more side-effect-y at higher doses over years for some people, and drug holidays on weekends or summers are reasonable for some patients, not for others. The cardiac caveat applies forever here, not just at the start. Anybody who’s been on a stimulant for ten years and never had blood pressure rechecked, or never had a conversation about what to do if BP creeps, has been getting medication management, not psychiatry. And the older you get, the more that conversation matters. Starting somebody on a stimulant for the first time at age 55 with three cardiac meds on board is genuinely fraught, and anybody who waves that off is a damn liar.
For antipsychotics, the reassessment is more aggressive because the long-term risks are higher. If a guy had a single psychotic episode 12 years ago and has been stable on Abilify the entire time, the question of whether he still needs to be on it is a real question, not a rhetorical one. Sometimes the answer is yes. Sometimes the answer is taper carefully and see what happens. Neither answer is the wrong one, and neither one gets asked in a five-minute med-check appointment.
What this looks like in real life
Say you’ve got a guy, retired, who had been on Paxil since the late 90s. Originally started for what sounded like a single depressive episode during a difficult divorce. He’d been on the same 40mg dose for almost three decades. Nobody had ever discussed coming off. He’d seen six different prescribers over the years, every one of whom looked at the chart, saw he was stable, and signed the refill.
He came to me because his new PCP wouldn’t keep prescribing it and told him to find a psychiatrist. We took the history. The original episode was probably real depression. The continuation through year five was probably reasonable. The continuation through year twenty-five was not a decision anybody had made, it was momentum.
So we did a slow taper. Real slow, because Paxil is one of the worst drugs in the class to come off. Took fourteen months. He had a rough patch around month eight where he wasn’t sure if he was relapsing or withdrawing, and we slowed it down, sat at a low dose for two months, then resumed. He’s been off for a year now and he’s fine. Better than fine, honestly. Sexual function came back, which he hadn’t realized he’d been missing because it had been gone since the Clinton administration. The family jewels are shining again, his words, not mine.
He’s not mad at the medication. It probably did its job in 1998 and saved him from a much worse year than he otherwise would’ve had. He’s mildly annoyed that nobody asked the question for two and a half decades. That’s a fair thing to be mildly annoyed about.
The default is refills happen indefinitely without anyone asking the question. It’s not necessarily wrong to stay on a medication for decades. It IS wrong to stay on it for decades without ever asking whether it’s still doing the job you started it for.
The patient autonomy piece
If you want to stay on your medication for the rest of your life, that’s your call. I’m a provider, not a parent. The job is to lay out the honest take on what we know, what we don’t know, what we’d want to watch as the years go on, and then the decision is yours. Some patients hear the long-term picture and decide they want to try coming off. Some hear it and decide they’d rather keep what’s working and accept the monitoring. Both are defensible answers. The wrong answer is to never have the conversation, which is currently what happens to most patients on long-term psych meds.
If we’re being honest, what’s nice about modern psychiatry is that the long-term picture for most of these medications has turned out to be better than the older generation of clinicians feared. The SSRIs haven’t produced the disaster cohort some predicted in the 90s. Lithium at proper monitoring lets people live full normal lives. Modern atypical antipsychotics, with weight and metabolic monitoring, are tolerable long-term for a lot of patients who wouldn’t have functioned at all on the older drugs. The medications mostly do what they say and the worst-case scenarios have not arrived. That’s a thing worth saying, because the discourse online tends to skew toward the worst stories.
What to ask your prescriber
Once a year, ask: am I still on this for the original reason, or has the reason quietly changed without anyone saying so. What would happen if we tried to come off. What’s the monitoring plan look like for the long-term risks of this specific medication, and are we actually following it, or are we just saying we are.
If the answer is “we just refill it,” you can press for a real conversation. If your prescriber won’t have one, your prescriber is the problem and not your medication. There are plenty of people who’d be willing to actually think about your case, including some who are taking new patients. Refill momentum is not a treatment plan.
Bottom line
Long-term medication is reasonable, defensible, and for many patients the right call. Long-term medication on autopilot, without periodic reassessment, is just sloppy. The question of whether you still need the drug is allowed to be asked, and the answer might be yes, and the answer might be no, and finding out which one is worth the trouble. Anybody who’s signing off on twenty-five-year-old refill orders without ever having the conversation isn’t doing the job. Ask the question. Ask it of yourself first. The medication isn’t sacred, your case is.
