Lorazepam (Ativan) Detox Guide

Even though lorazepam (Ativan) is a common prescription medicine for treating anxiety and sometimes insomnia, it can lead to physical dependence and withdrawal.1 This is especially true if you take it more often, in higher doses, or longer than prescribed.2 Withdrawal symptoms can be serious and often need medical treatment.2 In this article, you will learn about the symptoms and risks of Ativan withdrawal, what to expect from detox, and how to find help.

Lorazepam (Ativan) Withdrawal Symptoms

Ativan withdrawal symptoms begin shortly after suddenly stopping or reducing your dose of Ativan.2 Withdrawal symptoms vary widely from person to person. Symptoms can be very uncomfortable and, in rare cases, even dangerous if left untreated.2–4

Acute withdrawal signs and symptoms of Ativan may include:2–4

  • Anxiety or panic attacks.
  • Dizziness.
  • Depression.
  • Feeling fearful, irritable, or restless.
  • Numbness or tingling in the feet or legs.
  • Headache.
  • Being unable to focus or concentrate.
  • Increased heart rate and blood pressure.
  • Dilated (enlarged) pupils.
  • Increased sensitivity to light, sound, and touch.
  • Sweating.
  • Tremors (shakiness) and muscle twitching.
  • Trouble sleeping (insomnia).
  • Weight loss.
  • Hallucinations (seeing or hearing things that aren’t there).
  • Delirium (extreme confusion).
  • Psychosis (when you believe things that aren’t true and don’t know these ideas aren’t based in reality).
  • Seizures.

Symptoms of anxiety and insomnia may appear again when you stop taking Ativan, especially if you stop suddenly.4 That is, if you were taking it to treat anxiety, you may have anxiety again and if you were taking it for insomnia, you may have insomnia again.

These are known as rebound symptoms, and can be more severe than they were before treatment.4 Rebound anxiety symptoms can last at least 2 weeks, while sleep troubles can last at least 3 days.4

Post-Acute Withdrawal Symptoms (PAWS)

About 3 in 20 long-term Ativan users will have symptoms that last beyond (or appear again after) the acute stage of withdrawal. This is called post-acute withdrawal syndrome, or PAWS. PAWS symptoms can last for months or years after quitting Ativan use and may change over time in appearance and severity. PAWS symptoms may include:3–5,9

  • Anxiety.
  • Depressed mood.
  • Feeling like there are bugs under the skin.
  • Increased sensitivity to light, sound, or smell.
  • Irritable bowel syndrome.
  • Memory loss.
  • Tingling of the skin, or feeling “pins and needles.”
  • Trouble falling or staying asleep, or having nightmares.
  • Twitching or jerking muscles.
  • Hallucinations.
  • Ringing in the ears.

Lorazepam (Ativan) Withdrawal Timeline

How bad withdrawal symptoms are and how long they last will vary from person to person. It depends on how much Ativan you take, how long you’ve been taking it, and whether or not you take other sedatives or tranquilizers, mix with alcohol, or have other health issues.2–4 Using other substances can make withdrawal symptoms worse.3 This is especially true for substances with similar effects to Ativan, like alcohol or other central nervous system depressants.3 This is because these substances have additive effects, meaning when taken together they increase your risk of side effects.

In general, symptoms often begin 2 to 10 days after you stop taking Ativan.6 The symptoms then often slowly build for the next 2 weeks before slowly resolving in 1 to 2 weeks.4 But for those with a history of very heavy, long-term use, withdrawal symptoms may last even longer.

PAWS symptoms, when they appear, often begin a week or two after the acute withdrawal phase and last 6 to 12 months or longer.4 Anxiety symptoms can last for up to 2 years or more.4

Can You Die from Lorazpam (Ativan) Withdrawal?

Some withdrawal symptoms can be dangerous and need medical attention, especially if symptoms are severe.2–4,6 Potentially severe withdrawal symptoms include the following:2–4,7

  • A reduction in your body’s ability to regulate basic, involuntary body functions, including heart rate, breathing (respiratory) rate, and temperature. This can be dangerous and may need medical care right away, especially if you have other medical issues or withdrawal syndromes from other substances.
  • Withdrawal delirium may be life-threatening and need immediate medical care when severe. Symptoms can include feeling very disoriented and confused, psychosis, hallucinations, and seizures.
  • Seizures are rare but can be very dangerous and need medical attention when they do happen. These are more likely when you’ve been taking high doses of Ativan. Your risk for seizures is higher and the seizures can be worse if you already have a seizure disorder, take other medicines that increase the risk of seizure (benzodiazepines, sleep medicines, some depression medicines), or have alcohol use disorder.

How to Stop Taking Lorazepam (Ativan) Safely

Medical detox in an inpatient setting can work well for severe Ativan withdrawal, where symptoms can be dangerous and even fatal.7,8 Inpatient treatment helps ensure your safety while managing uncomfortable and possibly dangerous symptoms.7 Doctors often advise inpatient detox for those who:3,7

  • Take high doses of Ativan.
  • Have been using or misusing Ativan for a long time.
  • Also use alcohol or other medicine.
  • Have a history of seizures or other mental or physical illnesses.

During detox, medical staff will slowly wean you off of Ativan.7 This is called tapering and means taking smaller and smaller doses over time before stopping completely.7 Your care team may also switch you to a similar long-acting benzodiazepine that has a lower risk of being misused, such as Librium (chlordiazepoxide) or Klonopin (clonazepam).8

Can I Stop Lorazepam (Ativan) Cold Turkey?

Ativan withdrawal can be dangerous or even fatal.7 So before you decide to quit Ativan cold turkey, you should speak to your doctor. They can help assess the risks you may face during withdrawal, as well as identify the right level of treatment that will meet your recovery needs and respect your preferences while keeping you comfortable and, most important, safe.

Withdrawal symptoms can worsen quickly and, though rare, seizures are possible without any warning even if you have no other withdrawal symptoms.7 Cravings and other stressful withdrawal symptoms may also make it hard to follow a tapering schedule during outpatient detox, and this may increase your risk of relapse.3 Professional detox centers offer structure and support away from influences that could promote substance misuse. This can ease the withdrawal process in a way you won’t get detoxing at home.
