How Long Does Hydroxyzine Stay In Your System?
Hydroxyzine is an antihistamine to treat allergic skin reactions, anxiety, and tension. It can also be used as a sedative before or after general anesthesia.
Hydroxyzine will stay in your system for about 100 hours, on average, but its clinical effect may wear off before this time. Hydroxyzine has a half-life of about 20 hours. The half-life of a drug is the time it takes for the plasma (blood) concentration to be reduced by 50% from its original value.
However, the duration of action of hydroxyzine may vary depending on the dose, the individual, and the condition being treated. Some sources suggest that hydroxyzine wears off in 3 to 6 hours, while others say it can last for over 24 hours in some people.
Hydroxyzine may cause side effects such as drowsiness, dry mouth, headache, or dizziness. It may also impair your thinking or reactions, so be careful if you drive or do anything that requires you to be alert. Hydroxyzine can also cause a severe heart problem, mainly if you use certain medicines simultaneously. Tell your doctor about all your current medicines and any you start or stop using.
You should not use hydroxyzine if you are allergic to it or have certain medical conditions such as long QT syndrome, glaucoma, heart disease, or electrolyte imbalance. Hydroxyzine may also harm the unborn baby or cause birth defects. Talk to your doctor before using hydroxyzine if you are pregnant or breastfeeding.

Hydroxyzine Half Life
Hydroxyzine is an antihistamine to treat allergic skin reactions, anxiety, and tension. It can also be used as a sedative before or after general anesthesia.
The half-life of a drug is an estimate of the time it takes for the concentration or amount of the drug in your body to be reduced by exactly one-half (50%). The symbol for the half-life is t½.
Knowing the half-life of a drug is essential for determining how often to take the drug, how long it will take to reach a steady state in your body, and how long it will take to be eliminated from your body. It can also help you avoid drug interactions, side effects, and overdose.
Hydroxyzine has a half-life of about 20 hours for adults. This means that after 20 hours, you will have 50% of the original amount of hydroxyzine left in your body. After another 20 hours, you will have 25% left, and so on.
However, the duration of action of hydroxyzine may vary depending on the dose, the individual, and the condition being treated. Some sources suggest that hydroxyzine wears off in 3 to 6 hours, while others say it can last for over 24 hours in some people.

Hydroxyzine Factsheet
Hydroxyzine Overview
Hydroxyzine is an antihistamine medication for itching, anxiety, and nausea. It works by blocking the effects of histamine, a natural chemical that causes allergic reactions. Hydroxyzine can also be used as a sedative before or after surgery. Hydroxyzine is available by prescription only and can cause side effects such as drowsiness, dry mouth, and heart problems.
How long does hydroxyzine stay in your system? It should not be used by people who are allergic to it or have certain medical conditions. Hydroxyzine has a half-life of about 20 hours, which means it takes about that long for half of the drug to leave the body. However, the effects of hydroxyzine may last longer or shorter depending on the dose and the individual.
Hydroxyzine Withdrawal Symptoms
Hydroxyzine withdrawal symptoms are not familiar or severe, as this medication is not known to cause physical dependence or addiction. However, some people may experience a rebound of anxiety, insomnia, or itching when they stop taking hydroxyzine, especially if they have been using it for a long time or at high doses.
These symptoms are usually mild and temporary and can be managed by gradually tapering off the medication under a doctor’s supervision. Some people may also experience side effects from hydroxyzine while taking it, such as drowsiness, dry mouth, headache, or dizziness. These side effects are usually mild and go away with time or by adjusting the dose.
Hydroxyzine Side Effects
- Sedation: You might feel drowsy or sleepy or have trouble focusing while taking hydroxyzine. This can affect your ability to drive or do other tasks that require alertness. This side effect is more common than with other medications used for anxiety.
- Dry mouth: Hydroxyzine can reduce the production of saliva in your mouth, which can make it feel dry and uncomfortable. You can try drinking water, chewing gum, or sucking on hard candy to relieve this side effect.
- Nausea: Hydroxyzine can sometimes make you feel sick, especially if you take it on an empty stomach. You can take it with food or milk to prevent or reduce nausea.
- Headache: Hydroxyzine can cause a mild headache in some people. You can try taking a pain reliever such as acetaminophen or ibuprofen to ease the pain.
- Dizziness: Hydroxyzine can lower your blood pressure and make you feel dizzy or lightheaded when you stand up. You can try getting up slowly and holding on to something for support to prevent falls.
- Heart problems: Hydroxyzine can affect the electrical activity of your heart and cause a severe condition called QT prolongation, which can lead to irregular heartbeats, fainting, or even sudden death.
This is more likely to happen if you have a history of heart problems, use certain other medications, or have low levels of potassium or magnesium in your blood. You should tell your doctor about all your medicines and get regular electrocardiograms (ECGs) to monitor your heart while taking hydroxyzine.

Does Hydroxyzine Build Up In Your System?
Hydroxyzine is generally not known to accumulate or build up in the body over time. It is classified as a short-acting medication, meaning its effects are typically felt for a limited duration.
After taking hydroxyzine undergoes various processes in the body, including absorption, distribution, metabolism, and elimination. The drug is metabolized by the liver and primarily eliminated through the kidneys through metabolites. The half-life of hydroxyzine, which is the time it takes for half of the drug to be eliminated from the body, is reported to be around 20-25 hours in adults.
Due to its relatively short half-life, hydroxyzine is not expected to accumulate significantly in the system with regular use. However, it is essential to note that age, liver function, kidney function, and dosage frequency can influence the drug’s clearance from the body.

Video Script
“I wanted my life back. I was a shell of a person. I wanted to be trusted; I wanted relationships back that I lost, mainly my children and family. It started innocent enough, I got into a car accident, and then I got sucked into the whole, you know, medication issue with the pills. And before I knew it, I was in a cloud. I was sucked in by addiction, and with my mind, I kept thinking it was OK because a doctor was prescribing this for me, a doctor was giving me this, a doctor was giving me that.
So, I didn’t think I was doing anything wrong. Level Up supports my family and my relationships with my family, and they’ve helped me grow as a person. When I first started there, I was so intimidated and scared, you know? But, they’ve taught me, they’ve taught me how to come into my own. And then, you know, when I get the call from my twenty-one-year-old daughter in the middle of the day, to say ‘I love you, Mom.’ that’s amazing.”
