How Long Does Hydroxyzine Stay In Your System
How long do hydroxyzine’s effects last? And how long does it stay in your system? – Hydroxyzine is a type of drug called an antihistamine, It works by attaching to histamine receptors (binding sites) in your body. This produces a calming effect that helps relieve anxiety and itching.

  1. You may continue to have these effects from hydroxyzine for several hours after you take the drug.
  2. Hydroxyzine’s half-life can be used to figure out how long the drug stays in your system.
  3. The half-life of a drug is the time it takes for half of a drug’s dose to leave your body.
  4. Hydroxyzine’s half-life is about 14 hours.

So it takes about 14 hours for your body to get rid of half of a dose of hydroxyzine. Typically, it takes about five half-lives for a drug to completely leave your system. For hydroxyzine, this means the drug will stay in your system for about 70 hours after your last dose.

Hydroxyzine side effects – For some people, hydroxyzine side effects, which vary from mild to severe, can be unwelcome. When using hydroxyzine for sleep, common side effects include drowsiness, fatigue, nausea, dry mouth, and headache. Sometimes hydroxyzine makes people feel groggy, and they experience daytime sleepiness from its persistent effects after sleep.

  • Although this sedating effect is usually transient with regular or reduced usage, some people have reported that hydroxyzine leaves them feeling perpetually fatigued.
  • Using hydroxyzine for sleep also can make you feel nauseous.
  • Side effects like dry mouth and headaches are typically mild and short-lived, disappearing after a few days.

More severe hydroxyzine side effects include chest pain, severe headache, hallucinations and trauma nightmares, severe grogginess, respiratory depression, over-sedation and confusion in the elderly, and fainting. In the case of a hydroxyzine overdose, seizures may result.

  1. To avoid complications or serious side effects, do not take additional sleep-inducing substances when using hydroxyzine for sleep.

When does hydroxyzine peak?

Hydroxyzine (Atarax, Vistaril) – Hydroxyzine is an antihistamine with weak sedative, anticholinergic, and antiemetic properties. It produces sedation by inhibiting the hypothalamic H-1 histamine receptors involved in governing the sleep-wake cycle in humans.28 The antimuscarinic action of hydroxyzine inhibits the flow of saliva, resulting in various degrees of xerostomia.

Although clinical anxiolysis is sometimes reported with hydroxyzine, this effect is most likely related to the production of drowsiness and is not linked to specific actions on the neural substrates involved in anxiety. In normal doses, it has no cardiovascular or respiratory depressant effects. Absorption through the gastrointestinal tract is relatively rapid, with the onset of action occurring in 15 to 30 minutes.

Peak levels occur at 2 hours. Recovery is slow by modern standards, reflected by the mean half-life of 3 hours. It is available in two forms, hydroxyzine hydrochloride (Atarax) and hydroxyzine pamoate (Vistaril). Preparation: tablets, elixir Dosage: 0.5 to 1.0 mg/kg Side effects: prolonged drowsiness, ataxia, dry mouth.

Does hydroxyzine calm your mind?

Hydroxyzine for Anxiety – Hydroxyzine is a first-generation antihistamine that has been used for many years. Histamine is a chemical that your body releases as part of its immune response, which then stimulates histamine receptors. When histamine receptors are stimulated, it can cause symptoms like:

Anxiety, panic attacks, and tensionFlushing from the dilation of veinsCoughingLung and gastrointestinal contraction (such as asthma, intestinal cramping, or diarrhea)Hives, rashes, and other anaphylaxis symptoms

Because it is an antihistamine, hydroxyzine suppresses the effects of histamine. It is prescribed for:

Itching from hives or contact dermatitisSymptoms of anxiety, including generalized anxiety disorder (GAD)TensionPanic attacksSedation before general anesthesia

Hydroxyzine is in the same class of drugs as diphenhydramine (Benadryl), which is also a first-generation antihistamine, and cetirizine (Zyrtec), which is a second generation H-1 antihistamine that works in a similar way. All these medications act on H-1 histamine receptors. H-1 receptors are found all over the body, including:

Uterine liningCentral nervous system (CNS)Cardiac tissueGastrointestinal tissuesVascular cellsSmooth muscle of the lungsImmune cells

Hydroxyzine is not typically used long-term for anxiety, but may be prescribed as a way to relieve symptoms while longer-acting medications become effective. It may also be used for people who do not have chronic anxiety, but only need occasional relief during stressful moments or episodes.

  • By blocking the effect of histamine, it can decrease the anxiety-related effect that too much histamine can stimulate.
  • Hydroxyzine, unlike other antihistamines, also affects serotonin, a brain chemical that helps with feelings of calm, stability, and balance.
  • Because hydroxyzine can help your brain retain more serotonin, it might have a longer effect on feelings of anxiety and mood.

If insomnia or sleep problems are related to anxiety, hydroxyzine may be doubly impactful by having a sleep-inducing effect while also supporting serotonin levels.

Hydroxyzine is intended for short-term use only (less than 4 months) when used to treat anxiety. Using hydroxyzine long-term would be considered an off-label use for the drug because there are no studies looking at the long-term effects of hydroxyzine.

Some research suggests a link between long-term use of medications with anticholinergic properties, such as hydroxyzine, and dementia, particularly in older adults. Brain fog has also been reported with long-term use. Other conditions that hydroxyzine may be prescribed for, such as itchy skin due to an allergy, hives, dermatitis, or eczema, or as a sedative before surgery or other procedures, are generally short-lived and there is no need to prescribe hydroxyzine long-term.

Does hydroxyzine stop panic attacks?

Successful Treatment With Hydroxyzine of Acute Exacerbation of Panic Disorder in a Healthy Man: A Case Report To the Editor: In a given year, approximately 6 million American adults aged 18 years or older have panic disorder., To the best of our knowledge, this is the first report to document the successful treatment of acute exacerbation of panic disorder with hydroxyzine in a healthy adult.

Case report. Mr A, a 25-year-old man with a history of panic disorder, presented in 2010 to the emergency department complaining of chest pain, tachycardia, palpitations, hyperventilation, shortness of breath, sweating, nausea, and vomiting. Moreover, he reported derealization, a sense of doom, and constant fear of having another panic attack.

Mr A stated that he had been having panic attacks about 3 or 4 times daily for the previous week. Myocardial infarction was ruled out. Blood workup was inconclusive for any other medical cause. Mr A had been on venlafaxine 75 mg/d orally for the previous 6 months.

He had taken paroxetine 40 mg/d orally with no improvement for the 6 months prior to starting venlafaxine. Past medical, surgical, and family histories were not significant for any major illnesses. He was employed and single and smoked half a pack of cigarettes daily, but had no history of alcohol or illegal drug use.

The patient denied having any psychosocial stressors. Physical examination findings revealed no abnormalities. Mr A was admitted to the acute psychiatry unit for observation. Upon admission to the unit, hydroxyzine 25 mg 3 times daily was started with no other changes in medication or therapy.

The patient received prompt relief, and there were no further panic attacks during his 3-day admission or his 1-month follow-up. To the best of our knowledge, there are no published cases of successful treatment of acute exacerbation of panic disorder with hydroxyzine in healthy adults. There has been clear evidence of the anxiolytic efficacy of hydroxyzine.

In a controlled trial in generalized anxiety disorder patients, hydroxyzine demonstrated greater and more rapid cognitive improvement compared to lorazepam. Moreover, it has also shown a lack of organ toxicity and an absence of dependency. As reported in our case, an acute exacerbation of panic disorder was effectively managed by hydroxyzine in a healthy adult.

If practitioners recognize this association, extensive use of benzodiazepines may be prevented.1. Kessler R.C, Chiu W.T, Demler O, et al.

Does hydroxyzine give you a hangover?

Discussion – The primary result of this study was that both levocetirizine monotherapy and therapy with levocetirizine plus hydroxyzine were similarly effective in reducing urticarial symptoms, reducing night-time sleep disturbances and improving QoL.

  • In contrast, daytime sedation was significantly less with levocetirizine monotherapy in comparison with levocetirizine plus hydroxyzine.
  • The effectiveness of levocetirizine in relieving the symptoms of CSU and improving QoL confirms previous findings.14, 16 – 18 It is of particular relevance in this study that the subjective element of the UAS, the severity of pruritus, was similarly reduced by both treatment regimens, suggesting that the central effects of hydroxyzine do not contribute to the overall antipruritic effect, which is agreement with the hypothesis that histamine is involved primarily in the peripheral genesis of itch.19 Furthermore, both treatment regimens having a similar effect in reducing night-time sleep disturbances again indicates that it is the peripheral antipruritic effect of the nonsedating second-generation H 1 -antihistamine that is of prime importance rather than any central sedative effects.

What is very clear from this study is that patients receiving levocetirizine monotherapy were significantly less sedated during the day than they were before treatment at the beginning of the study, confirming the findings of Staevska et al,14 In contrast, when treated with levocetirizine plus hydroxyzine, patients experienced a similar level of sedation to those who were not treated.

Furthermore, patients receiving levocetirizine monotherapy experienced less daytime sedation than those receiving levocetirizine plus hydroxyzine. This strongly suggests that the detrimental sedative effects of hydroxyzine were due to its prolonged central nervous system effects. With a terminal half life of 20–25 h, 20 it is not surprising that hydroxyzine has hangover effects into the next day.

We believe that this study has two weaknesses. Firstly, we did not perform objective assessments of alertness or productivity. Even so, our study would support the conclusion of Murota et al,21 that pruritic diseases negatively impact on daily activity and impair productivity, and that this is improved in patients taking second-generation nonsedative, but not first-generation sedative, H 1 -antihistamines, and that the improvements correlated with the alleviation of itch and improved QoL.

The second weakness is that the length of the study, 10 days, is less than that of many similar studies in urticaria. This was because the study was performed at a tertiary referral clinic with patients from all over Bulgaria and we wanted to ensure a sustainable follow-up of patients, particularly given compliance issues.

In conclusion, the results of this study do not support the widely held belief that the most effective treatment for chronic urticaria is a nonsedating second-generation H 1 -antihistamine in the morning and a sedating first-generation H 1 -antihistamine, usually hydroxyzine, at night to enhance sleep.
