How Long Do Benzos Stay in Your System?

Last Updated on

Benzodiazepines, commonly known as “Benzos,” were created to help people who needed something to help them relax, decrease their anxiety and to help mentally/emotionally stabilize them so that they can lead healthy, productive lives.

They have also been used to help people with various medical problems including schizophrenia and panic attacks.

The problem is that not only do they work, but they sometimes work too well, and people have begun to use them recreationally to increase their physical and mental states of relaxation or to increase the effects of opiate or alcohol use.

One interesting thing revealed, in a study done by the National Library of Medicine in 2008, is that benzo use seems to be more prevalent in women and, for men and women, the percentage of benzodiazepine use increases with age.

Since 2008, the amount of people using benzos, whether for medical conditions or recreational use, has increased. This increased usage amount, according to The National Institute on Drug Abuse, is attributed to the increased amount of deaths related to benzo overdose.

Now that’s a quick overview done. Let’s talk about what you came here for: how long do benzos stay in your system.

What are Benzodiazepines?

Benzodiazepines are a group of medications prescribed for their strong sedative effects. Doctors prescribe them to patients who have problems with panic attacks, sleep disorders, anxiety, and social phobias.

This group of drugs helps patients with the mentioned disorders by acting as a tranquilizer and depressant to the central nervous system.

Benzos have also been used to help calm patients who are having alcohol withdrawals, helping them to calm down even though the potential for abuse to the benzos are very high and can become a replacement for the alcohol abuse.

It may sound strange, now that you are aware of the addictive possibility of Benzos, but they have also been widely used to help decrease the withdrawal symptoms of people who have abused heroin, cocaine, speed and other stimulants.

How Long do Benzos Stay in Your System?

Multiple personal factors can affect how long benzos stay in your system. There are various answers that you may find in your search, but the information below will give you a rough idea of how long it will take for benzodiazepines to clear your system.

Benzos Can be in Your:

  • Blood for about 2-3 days
  • Urine for approximately 3-6 weeks
  • Hair for around 90 days or 3 months [ we stock detox shampoo]

As mentioned above, these numbers aren’t solid and can be shorter or longer from person to person depending on the amount used, the length of use and sometimes even the weight of the person.

What is a Half-Life?

When you hear someone talking about the half-life of a drug they are talking about how long it will take your body to eliminate half of the amount of the drug taken.

As noted above, some benzos are short-acting, and others are long-acting. This affects the half-life as well.

Short-acting Benzos can have a half-life of fewer than 5 hours up to 24 hours. Long-acting Benzos can have a half-life of 24 hours or more.

Is There a Reliable Detox?

If someone has been using Benzodiazepines for quite some time, and have become dependent or addicted to them, the most reliable detox is a medical detox that happens in hospitals or detox centers and typically lasts for four weeks.

Detoxing at home is NOT advised. There are withdrawal symptoms that cannot be managed effectively at home, seizures are a hazard, and the possibility of mental dysfunction and brain damage are high.

To safely detox, an inpatient program is the most reliable way to remove the drugs from your body and live to tell about it.  An inpatient program will assure that you will get the rest, fluids and food you need to help combat the symptoms of benzo withdrawal.

Take a look at some of the benzodiazepine withdrawal symptom below and you will get a better understanding of why an inpatient detox program is the most reliable way to detox from benzos.  

The list includes:

  • Seizures
  • Psychosis
  • Hallucinations
  • Confusion
  • Increased anxiety
  • Headaches
  • Panic attacks
  • Impaired Judgement
  • Weakness

If you are in a position where you need to get the benzodiazepine out of your system in a hurry, the information above should tell you whether or not this is possible for you. If you have only used benzos occasionally and as needed for a particular condition, you might be alright.

But if you have been using them for awhile, either recreationally or to treat medical problems you are having, a quick “I can do this myself” plan is not the way to go.

If you are scheduled to have a urinalysis to see if there are toxins in your system, and you need your test to come back negative, don’t put your health in danger. There is another way.
