Several medications can help manage Xanax (alprazolam) withdrawal, but the most common and well-supported approach is switching to a longer-acting benzodiazepine and then gradually tapering the dose over weeks or months. Additional medications can target specific symptoms like insomnia, racing heart, and anxiety that persist during the taper.
Why Xanax Is Harder to Stop Than Other Benzodiazepines
Xanax leaves your body quickly. Its effects wear off in just a few hours, which means your brain experiences sharp dips between doses. These rapid fluctuations make withdrawal symptoms more intense and harder to control compared to longer-acting benzodiazepines that clear the body more slowly and evenly. This is why most tapering plans start by switching you to a different medication before reducing the dose.
Switching to a Longer-Acting Benzodiazepine
The most widely recommended strategy is transitioning from Xanax to a longer-acting benzodiazepine, most often diazepam (Valium) or sometimes clonazepam (Klonopin). These drugs stay active in your body for much longer, which smooths out the peaks and valleys that drive withdrawal symptoms. Guidelines from the American Society of Addiction Medicine endorse this switch as a standard approach, particularly for people who have been taking Xanax at higher doses or for extended periods.
The conversion isn’t one-to-one. Roughly 1 mg of Xanax is considered equivalent to about 10 mg of diazepam, though some references place it closer to 0.5 mg of Xanax per 10 mg of diazepam. Your prescriber will adjust based on how you respond. In a typical scenario, someone taking 1.5 mg of Xanax daily might be transitioned to 15 mg of diazepam, switching one dose at a time over about two weeks to make the changeover gradual.
Once you’re stable on the longer-acting medication, the actual taper begins. Current guidelines recommend dose reductions of 5% to 10% every two to four weeks. The taper should not exceed 25% every two weeks. For people with strong physical dependence, such as those who have taken a high dose for over a year, a slower pace of 5% to 10% every six to eight weeks is recommended. The final reductions, as you approach zero, are typically the slowest part of the process.
Pregabalin and Gabapentin for Withdrawal Symptoms
Pregabalin (Lyrica) has the most direct evidence for easing benzodiazepine withdrawal specifically. In one study of 282 long-term benzodiazepine users, 52% were completely benzodiazepine-free after 12 weeks of pregabalin treatment. Their withdrawal symptom scores dropped by more than half, and anxiety improved by 69%. About 83% of patients rated the tolerability as good or excellent.
In a separate controlled trial focused specifically on people tapering off Xanax, those given pregabalin had significantly less severe withdrawal symptoms during the taper compared to those given a placebo. About 51% of the pregabalin group became Xanax-free, versus 37% on placebo. Both pregabalin and the related drug gabapentin (Neurontin) work by calming overexcited nerve signaling, which is a core driver of withdrawal symptoms like anxiety, restlessness, and nerve pain.
Medications for Racing Heart and Tremors
Withdrawal often produces a surge of adrenaline-like activity: elevated heart rate, high blood pressure, sweating, and tremors. Two types of medication help with these physical symptoms. Clonidine, which acts on the brain’s stress-response system, brings down pulse and blood pressure. Beta-blockers like propranolol target the heart directly, slowing your heart rate and reducing the shaking and jitteriness that can make withdrawal feel unbearable.
Neither of these medications should be used alone to manage withdrawal. They don’t prevent seizures or address the underlying neurological rebound that causes withdrawal in the first place. They work best as add-ons to a tapering plan, taking the edge off the most distressing physical symptoms.
Help for Withdrawal-Related Insomnia
Sleep disruption is one of the most persistent withdrawal symptoms and often the last to resolve. Because the goal is to move away from addictive sleep aids, prescribers typically reach for non-habit-forming options. Mirtazapine, an antidepressant with strong sedating properties, is frequently used at low doses (often around 7.5 mg) to improve sleep during tapering. Multiple studies have confirmed it increases sleepiness and helps with insomnia, and it also addresses the co-occurring anxiety and loss of appetite that many people experience during withdrawal.
Trazodone is another commonly prescribed option for the same purpose. Melatonin, available over the counter, is sometimes used as a gentler sleep support alongside other medications.
Anticonvulsants for Seizure Protection
Seizures are the most dangerous risk of benzodiazepine withdrawal, and they can occur even during a supervised taper. Carbamazepine and valproate, both anticonvulsant medications, have been studied as aids during benzodiazepine detoxification. They can lower seizure risk and may also reduce anxiety and mood instability. Like the blood pressure medications above, these are used alongside a taper rather than as standalone treatments.
Flumazenil Infusions: A Specialized Option
Flumazenil is a medication that acts directly on the same brain receptors as benzodiazepines. At very low doses delivered through an IV over several days, it appears to “reset” receptors that have adapted to chronic benzodiazepine exposure. In one controlled study, patients who received low-dose flumazenil infusions alongside a standard taper had significantly fewer withdrawal symptoms, less craving, higher completion rates, and lower relapse rates afterward. In another case series, all 29 patients completed treatment, and 51% remained abstinent at six months.
This approach is only available in specialized clinical settings. The infusions typically run for four to seven days and require medical monitoring. It’s not widely accessible, but it represents a promising option for people with severe dependence who have struggled with conventional tapers.
Supplements With Some Supporting Evidence
L-theanine, an amino acid found in green tea, has shown anxiolytic (anxiety-reducing) properties in animal studies. It increases levels of calming brain chemicals like GABA and serotonin while also blocking certain excitatory receptors that become overactive during withdrawal. While the direct evidence in benzodiazepine withdrawal is limited, its mechanism of action is relevant, and it has FDA Generally Recognized as Safe (GRAS) status. It’s not a substitute for medical treatment, but some people use it as a mild complementary support during tapering.
What a Typical Treatment Plan Looks Like
In practice, most people tapering off Xanax don’t use just one medication. A realistic plan often combines a switch to a long-acting benzodiazepine for the taper itself, something like pregabalin or gabapentin to reduce withdrawal intensity, a sleep aid like mirtazapine or trazodone, and possibly clonidine or a beta-blocker if physical symptoms are prominent. The specific combination depends on your dose, how long you’ve been taking Xanax, and which symptoms are most troublesome for you.
The timeline varies widely. A straightforward taper for someone on a moderate dose might take two to three months. For long-term, high-dose users, tapers lasting six months to a year or longer are not unusual, and the guidelines explicitly support going that slowly when needed. The final 25% of the taper is often the hardest stretch, and many prescribers slow the reductions further as you approach the end.
