Can a psychiatric medication taken exactly as prescribed cause physical dependence?

Yes, and it happens to careful people who did everything their doctor asked. After months or years on an antidepressant, a gabapentinoid, or an antipsychotic, the brain adapts to the drug, and lowering the dose too quickly brings on withdrawal symptoms that have nothing to do with the original problem.

The pattern patients describe is a common one. A doctor says to cut the dose in half for two weeks and then stop, the second week is dizziness and electric jolts in the head, and the doctor concludes that the depression has come back.

Was it the depression? Was it the drug? Or, was it the speed? In most of these stories it was the speed. Withdrawal is not a character problem. It is a dose problem.

Dr. Leeds helps patients in Fort Lauderdale and across Florida come off of these medications slowly. So, what does a safe taper look like, and why do so many fail?

Dependence is not addiction.

Physical dependence means the body has adjusted to a medication and reacts when the medication is reduced. Addiction is a pattern of behavior, with craving, compulsive use, and continued use despite harm.

In fact, most people who struggle to come off of a prescribed antidepressant or antipsychotic are dependent and not addicted. They took a medicine the way they were told to, and the medicine did what long-term use does.

Unfortunately, the distinction is lost on much of the system that prescribed the drug. A person with withdrawal symptoms may be told they are drug seeking, or sent to a program built for addiction, when what they need is a slower taper. The difference between physical dependence and addiction decides everything about the treatment.

Dependence calls for a gradual, medically supervised taper. Nothing else.

Which psychiatric medications does Dr. Leeds help patients taper?

Antidepressants lead the list. That includes the SSRIs, or selective serotonin reuptake inhibitors, such as Prozac (fluoxetine), Zoloft (sertraline), Paxil (paroxetine), and Lexapro (escitalopram). It also includes the SNRIs, or serotonin-norepinephrine reuptake inhibitors, such as Effexor (venlafaxine) and Cymbalta (duloxetine), as well as Remeron (mirtazapine), an antidepressant of a different class.

Gabapentinoids are the second group: gabapentin (Neurontin) and pregabalin (Lyrica). Antipsychotics are the third, including Seroquel (quetiapine), Zyprexa (olanzapine), and Abilify (aripiprazole). Mood stabilizers and other psychotropic medications are taken case by case, after a consultation.

Benzodiazepines and the sleep medications that act on the same receptors have a page of their own, explained near the end of this one.

Dr. Leeds’ relationship to these drugs is a simple one. He tapers them. He does not treat with them.

Why is stopping an antidepressant so much harder than starting one?

Because the brain has spent months or years rebuilding itself around the drug, and has settled into a new normal that includes the medication. Take the medication away faster than the system can readjust, and the system objects.

The objection is described on the drug’s own label. The FDA label for Lexapro, and similar language on the other SSRI and SNRI labels, lists irritability, agitation, dizziness, electric-shock sensations, anxiety, headache, emotional instability, and insomnia among the symptoms reported when these drugs are stopped, especially abruptly. The same label recommends a gradual reduction rather than abrupt cessation.

Yet, these symptoms are routinely mistaken for a relapse. The Maudsley Deprescribing Guidelines draw the line this way: withdrawal begins within hours or days of a reduction, includes sensations such as the electric jolts patients call brain zaps that are not symptoms of depression, and eases when the previous dose is restored, while a relapse usually arrives weeks or months later. A doctor who cannot tell the two apart will keep you on the medication forever, with the best of intentions.

What are the Maudsley Deprescribing Guidelines, and what is hyperbolic tapering?

The Maudsley Deprescribing Guidelines are a reference written for taking patients off of psychiatric medications rather than putting them on. Their central idea is that the relationship between the dose of a drug and its effect on the brain is not a straight line. It is a curve, and the curve is steepest at the bottom.

An old radio makes the point. While no analogy is perfect, think of a volume knob that runs from ten down to zero. Turning it from ten to eight barely changes what you hear. Yet, the last click, from one to zero, is the difference between sound and silence.

A psychiatric medication behaves the same way at the receptor. Cutting a high dose in half removes less effect than it seems to, and cutting the last few milligrams removes far more. The Maudsley guidelines call the answer hyperbolic tapering. Each reduction is smaller than the one before it, so that the final steps are tiny, and each step costs the brain about the same amount of adjustment.

The conventional taper takes even steps, so the biggest shock lands at the end, exactly where the patient is most sensitive. Even steps are the wrong shape.

How does a doctor prescribe a dose smaller than the smallest tablet?

Fortunately, in liquid form. Several of these medications are made as a liquid by the manufacturer, and for the rest a compounding pharmacy can prepare a liquid, or capsules in exact small strengths, from a prescription Dr. Leeds writes. A dose is then measured on an oral syringe, and a reduction can be a fraction of a milligram.

Tablets cannot do this. While a pill splitter gets you to a half or a quarter, a quarter of the smallest tablet is still a large step at the bottom of the curve. This is where most home tapers break down, and it is not the patient’s fault.

Of course, the pharmacy does not decide the pace. The schedule is written for one patient and adjusted as that patient responds, which is why this page carries no milligram schedule. A schedule that was right for someone else is a guess for you.

What about gabapentin, Lyrica, Seroquel, and Zyprexa?

Gabapentin (Neurontin) and pregabalin (Lyrica) are prescribed for nerve pain, anxiety, and sleep, and they cause physical dependence like anything else that quiets the nervous system. The FDA label for Lyrica lists insomnia, nausea, headache, anxiety, sweating, and diarrhea after abrupt or rapid discontinuation and advises tapering gradually rather than stopping. The Maudsley Deprescribing Guidelines apply the same hyperbolic principle to gabapentinoids.

Seroquel (quetiapine) and Zyprexa (olanzapine) are a different story. Both were approved for schizophrenia and bipolar disorder, and both ended up widely prescribed for insomnia, a use that is not among the approved indications on either FDA label. A drug became a sleeping pill because it makes people drowsy. Drowsiness is a side effect, not an indication.

Stopping an antipsychotic abruptly brings its own withdrawal, and the Seroquel label describes insomnia, nausea, and vomiting after abrupt cessation and advises gradual withdrawal. In Dr. Leeds’ practice, antipsychotics come down on the same principle as everything else, in smaller and smaller steps, at a pace set by the patient’s response. And, he does not treat with them, including for the insomnia they were handed out for.

How long does a psychiatric medication taper take?

Longer than the two weeks many patients were given. A taper measured in weeks is usually a taper that is too fast, and the tapers Dr. Leeds supervises run many months. After years on a medication, a year or longer is common.

When a reduction brings symptoms, that is information, and the answer is to hold the dose, or to go back up a step, until things settle. The Maudsley Deprescribing Guidelines say exactly this for antidepressants: hold the current dose for longer, or return to the last dose at which the symptoms were tolerable.

While pushing through a rapid taper may feel like strength, it usually leaves the nervous system less stable than it was. Holding is not failure. It is the taper working.

Nobody can predict in advance how a particular brain will respond to a particular reduction. So, the plan is rewritten as it goes, and that is the reason Dr. Leeds sees tapering patients every week rather than once every few months.

Does protracted withdrawal get better?

In most cases, it does, though after months of symptoms that come and go, it can feel permanent. Protracted withdrawal, meaning withdrawal symptoms that continue long after a taper or an abrupt stop, is real, and it most often follows an abrupt stop or a taper that was too fast.

The pattern patients describe is windows and waves. A window is a stretch of days when you feel close to normal, and a wave is a return of symptoms that seems to come from nowhere. Over time the windows lengthen and the waves shorten, and that is what recovery looks like from the inside.

A nervous system in withdrawal is not broken. It was pushed out of balance, and it is finding its way back. The first sign of healing is usually not a cure. It is a little more sleep and a little less fear.

Fear amplifies every symptom. So, a doctor who explains what is happening is not merely being polite. The explanation is part of the treatment.

What does informed consent mean when a medication is being tapered?

Many of Dr. Leeds’ patients were never told, when the medication was started, that stopping it could be difficult. That is the consent conversation that did not happen.

Consent at the start of a taper covers the risks first: withdrawal symptoms and the possibility of protracted withdrawal. It covers the benefits and the alternatives, including staying on the medication, and it covers how the taper is expected to end before the first reduction is made.

And, it covers your right to say no. You may decline a reduction, stop the taper, or change your mind, without any penalty to your care. Consent is a conversation that continues at every visit, not a signature on the first day.

What about benzodiazepines and sleep medications?

Benzodiazepines such as Xanax (alprazolam), Klonopin (clonazepam), Ativan (lorazepam), and Valium (diazepam) are tapered by a protocol of their own, the crossover taper to diazepam described in the Ashton Manual by the late Professor C. Heather Ashton. Sleep medications such as Ambien (zolpidem) and Lunesta (eszopiclone) act on the same receptors and are tapered the same way. Everything about that work is on the benzodiazepine dependence and tapering page.

One warning stands above everything else: never stop a benzodiazepine suddenly, and never let a taper turn into an abrupt stop. Sudden discontinuation can trigger seizures and can be life-threatening. However a taper is shaped, it should be gradual and medically supervised.

If a seizure or any other medical emergency happens during a taper, call 911. If you have thoughts of suicide at any point, call or text 988, the Suicide and Crisis Lifeline.

How Dr. Leeds works with tapering patients in Fort Lauderdale and across Florida.

Dr. Leeds practices concierge telemedicine for patients in Florida, with an office in Fort Lauderdale for in-person visits. The practice is private and not insurance-based, and every appointment is with Dr. Leeds himself, never with a substitute provider, a coach, or a non-physician practitioner.

Tapering patients are seen weekly by video, often for up to an hour, and have text access to Dr. Leeds between visits for urgent questions. The plan belongs to the patient, who sets the pace within the limits of safety.

He serves on the medical advisory board of the Benzodiazepine Information Coalition, and deprescribing is the center of his practice, not a side service. Whether the practice is the right fit is decided at a first consultation.
