Why does the skin burn during benzodiazepine withdrawal, and what helps?

Burning skin is a sensory symptom of withdrawal, and it is real.

Burning skin is a sensory symptom of benzodiazepine withdrawal. Patients describe skin that feels sunburned when there has been no sun, a hot prickling across the back or the arms, or a sting under a collar that the collar did not cause. The sensation is real, and in most cases it does not mean that the skin or the nerves have been damaged.

It tends to appear in the days after a dose reduction, or when a dose is late or missed. Some people feel it on a steady dose, which is a sign of tolerance, the state in which the same dose no longer holds withdrawal at bay.

Unfortunately, many people who search for this symptom have already been told, by a relative or an emergency department, that the problem is addiction. It is not. A person who took a benzodiazepine as prescribed and now has burning skin when the dose comes down has physical dependence, and dependence is not addiction. Dependence is a change in the nervous system that prescribed use can produce, and the treatment is a gradual, medically supervised taper. Dr. Mark Leeds, an osteopathic physician and deprescribing specialist in Fort Lauderdale, Florida, starts every taper his practice supervises from that distinction.

The nervous system is hyperexcitable, and the skin is where you feel it.

Benzodiazepines work by boosting gamma-aminobutyric acid (GABA), the brain’s main calming signal. With steady use over weeks and months, the receptors that respond to GABA become less responsive, so the brain needs the drug just to keep its ordinary level of calm. The Ashton Manual, by Professor C. Heather Ashton at benzo.org.uk, describes this adaptation in Chapter I.

When the dose comes down, the drug’s boost shrinks before the receptors have readjusted. The result is what Chapter III of the Manual calls a hyperexcitable state of the brain and the peripheral nerves. The Manual lists a heightened sensitivity to all sensations, including touch, along with tingling, numbness, sensations of hot and cold, a feeling of insects crawling on the skin, and deep burning pain.

A smoke detector set too sensitive goes off when someone makes toast. During withdrawal, the nerves that report heat and pain are set that high, so warmth from a shower, the rub of a sleeve, or nothing at all sets off the alarm as burning. The detector is not broken, and the setting drifts back down as the dose comes down slowly.

Professor Ashton adds a reassurance worth repeating. Nerve conduction tests in patients with these symptoms showed nothing abnormal, and she calls the symptoms disconcerting but usually nothing to worry about.

What does it feel like, and how long does it last?

Patients often describe hot spots on the scalp, face, back, or thighs, or a burning line down one arm that moves somewhere else the next day. It may come with tingling or numbness, covered in a separate article on paresthesia during benzodiazepine withdrawal. Or, it may arrive with flushing, itching, and hives that feel like an allergy, covered in the article on histamine bursts during benzodiazepine withdrawal.

The symptom moves in waves. It is often worse in the days after a cut, at night, in heat, and under stress, and it eases in between. A bad day after a reduction is information about the pace of the taper, not proof that something has gone wrong for good.

Is it permanent? In most cases, it is not. Chapter III of the Manual says these sensory symptoms resolve in time, and its table of protracted symptoms is honest that in some people they recede gradually over a year and occasionally longer, declining in severity as they go. What can be said is that the nervous system heals, and it heals best when it is not being pushed.

What helps when the skin is burning?

Cooling is what patients report helps most, because the sensation is heat that is not really there. A cool damp cloth on the hot patch, a cool shower rather than a hot bath, a fan, loose cotton instead of wool, and shade instead of direct sun all lower the input that the nerves are overreporting. Some patients keep a cold pack wrapped in a towel by the bed for the night flares.

Gentle movement helps as well. A walk, easy stretching, or slow yoga tends to settle the nervous system and pull attention away from the skin. Hard exercise, saunas, and hot yoga do the opposite for many people, so effort is best kept mild until the symptom fades.

Slow breathing and other relaxation practices lower the level of arousal, and a calmer nervous system reports less burning. None of these measures cures the symptom or speeds the healing underneath it. They make the waiting bearable, which is what a comfort measure is for.

What about a medication for the burning? Dr. Leeds tapers psychiatric medications rather than adding them to a withdrawal, and no medication reliably switches this symptom off. The honest answer is the one below.

When the burning flares, slow the taper or hold it.

A flare after a dose reduction means the reduction was larger, or came sooner, than this nervous system could absorb. Fortunately, the response is simple: stop reducing, stay at the current dose until the symptom settles, then resume with smaller steps. Chapter II of the Ashton Manual says the patient may stand still at any stage and take a vacation from further withdrawal for a few weeks, and that the patient, not the schedule, is the best judge of the pace.

Professor Ashton’s advice is to reduce by up to one tenth of the dose at each step, and the Maudsley Deprescribing Guidelines describe hyperbolic reductions, in which each cut is smaller than the one before. The shape matters more than any number. The last part of a taper is usually the slowest, and burning skin is one of the symptoms that tells the patient and the doctor when to slow down.

A hold is usually enough. Chapter II of the Manual advises, as far as possible, never going backwards, and most flares settle at the current dose without any step back up. When a flare does not settle, a small increase to the last dose that felt steady is a stabilization decision, made with the prescriber, and it is not a failure. Talk to your prescriber before any change, and ask for a hold or a smaller step rather than a bigger cut to “get it over with.” A bigger cut is the one change that makes this symptom worse.

If the burning tracks the clock, easing after each dose and returning before the next, the drug may be too short-acting for a smooth taper. The Manual’s answer is a crossover taper to diazepam, replacing one dose at a time, which Dr. Leeds uses where it helps and explains on the page about how he applies the Ashton Manual. For many patients, the swings between doses are what set the skin alight.

Stopping abruptly is never the answer.

In September 2020, the United States Food and Drug Administration (FDA) updated the boxed warning on every benzodiazepine to cover abuse, misuse, addiction, physical dependence, and withdrawal reactions. The label states that dependence can develop within days to weeks of steady use, even as prescribed, and that stopping abruptly or cutting too quickly can cause withdrawal reactions, including seizures, which can be life-threatening, and it calls for a gradual taper.

Call emergency services for a seizure or any medical emergency. A person who cannot bear the burning is in far less danger holding the dose than stopping it.

Chapter II of the Ashton Manual allows one exception, for triazolam, a benzodiazepine eliminated so quickly that the Manual says it can be stopped abruptly without substituting a long-acting drug. Dr. Leeds does not recommend abrupt stopping even there, and prefers a gradual taper for every benzodiazepine and z-drug, consistent with the drug’s own label.

Not every burning sensation is withdrawal.

Most burning skin during a taper is the hyperexcitable nervous system described above. Some is not. Burning with a rash, blisters, swelling, or fever, burning confined to one band of skin on one side of the body, or burning with weakness in a limb deserves an examination, because a taper does not make a person immune to other conditions.

Patients in withdrawal are understandably wary of doctors, often for a good reason: the prescription that caused the dependence came with an assurance that it was safe. Yet, a wary patient still deserves a doctor who will look at the skin, rule out the other causes, and then say plainly that this is withdrawal and it will pass.

Dr. Leeds treats a flare as information about the pace.

Dr. Leeds’ practice offers one service, medically supervised benzodiazepine and z-drug tapering, by telemedicine for patients in Florida, on a concierge basis rather than through insurance. Every taper starts with informed consent: the risks first, the alternatives, an exit plan, and the patient’s right to decline or pause at any point. The pace is patient-directed, over months and sometimes longer, with hyperbolic reductions and a crossover taper to diazepam where it helps.

When a patient’s skin starts burning after a cut, he and the patient hold the taper, wait for the nervous system to catch up, and resume with a smaller step. His practice treats the flare as information, not as a reason to push through. Contact Dr. Leeds to talk about a taper that moves at the pace your nervous system can tolerate.
