Hydroxyzine for Anxiety: Unveiling Its Efficacy and Usage

Hydroxyzine is an anti-histamine (allergy) medication that is often prescribed for the treatment of various conditions including some forms of anxiety. Recognized for its anxiolytic (anti-anxiety) properties, hydroxyzine works by inhibiting certain activity in the central nervous system, contributing to a calming effect for those who experience symptoms of anxiety. Unlike many other anxiolytics, hydroxyzine is not classified as a benzodiazepine and therefore does not carry the same risk of dependency or high potential for abuse.

  • Hydroxyzine has proven efficacy for treating symptoms of anxiety.
  • It offers advantages including a lower risk of dependency and withdrawal.
  • Proper medical guidance is critical for safe hydroxyzine administration.
  • Hydroxyzine can cause side effects like sleepiness, drowsiness, and dry mouth

Hydroxyzine Overview

Hydroxyzine is a medication primarily used as an antihistamine for the treatment of itching, anxiety, and nausea. It is also known for its sedative properties. Here’s a closer look at its chemistry, use as an antihistamine, and available brands and forms.

Chemical Properties and Mechanism of Action

Hydroxyzine belongs to a class of medications known as diphenylmethanes. Specifically, there are two main types of hydroxyzine: Hydroxyzine Hydrochloride and Hydroxyzine Pamoate. As an antihistamine, hydroxyzine blocks the activity of histamine, a substance in the body that causes allergic symptoms. While both forms are effective in treating symptoms of anxiety and itching, their chemical properties differ slightly, which can affect their solubility and onset of action.

Hydroxyzine as an Antihistamine

In addition, hydroxyzine acts as an antihistamine drug. Histamine is a substance that can cause things like rashes or hives when it is released in the body such as an allergic reaction. By blocking the action of histamine, hydroxyzine can prevent hives and rashes. Hydroxyzine can also cause sedation, meaning it can make users feel sleepy or drowsy. This is why it can be prescribed to treat anxiety. Patients who are anxious or agitated can take hydroxyzine (also known as Vistaril) to help them calm down.

Brands and Forms

Hydroxyzine is available under several brand names, including Atarax and Vistaril. Atarax generally refers to hydroxyzine hydrochloride formulations, while Vistaril is typically hydroxyzine pamoate. Both are available in various forms, including tablets, capsules, and a syrup. Additionally, it is chemically related to other antihistamines like Cetirizine (Zyrtec), and Levocetirizine (Xyzal), which are used primarily for the treatment of allergic conditions and usually have less sedative effect compared to hydroxyzine.

Hydroxyzine for Anxiety Disorders


Hydroxyzine is an antihistamine medication recognized for its effectiveness in treating anxiety symptoms. As an alternative to benzodiazepines, it alleviates anxiety symptoms without the serious side effects commonly associated with more traditional anxiolytics.

Effective Use in Treating Anxiety Symptoms

Hydroxyzine has been found to be more effective than placebo for individuals experiencing symptoms of generalized anxiety disorder (GAD), particularly in reducing overall anxiety levelsClinical studies demonstrate hydroxyzine’s ability to improve mood and mitigate anxious feelings without the risk of rebound anxiety or dependency that might come from medications in the family of alprazolam, commonly known as Xanax.

Comparing Hydroxyzine to Other Anxiolytics

When comparing hydroxyzine to other anxiolytics, such as buspirone and benzodiazepines, different studies present nuanced findings. For instance, a three-month double-blind study confirmed that hydroxyzine is effective and posed a lower risk of withdrawal symptoms. Another study shows hydroxyzine as a competent treatment option with efficacy comparable to buspirone and an advantage over placebo treatments.

Long-Term Management of Anxiety Disorders

For the long-term management of anxiety disorders, hydroxyzine can be an important part of the treatment plan. While it has been shown to assist in symptom management, determining the appropriate duration and dosage requires careful consideration and ongoing assessment by healthcare providers. Maintenance of symptom relief without the development of dependence is a key benefit in the use of hydroxyzine over benzodiazepines for chronic conditions such as anxiety disorders.

Dosage, Administration, and Safety

When considering hydroxyzine as a treatment for anxiety, proper dosage, administration, and safety are crucial. These factors depend on the patient’s age, the presence of other medical conditions, and specific response to the medication.

Potential Side Effects and Adverse Reactions

Hydroxyzine can cause various side effects, including:

  • Sedation
  • Dry mouth
  • Drowsiness
  • Headache
  • Nausea

In rare cases, it can affect the heart rhythm, a condition known as QT prolongation. An overdose of hydroxyzine can be dangerous, leading to extreme drowsiness or even unconsciousness or death. For these reasons, this medication must be taken as prescribed by a healthcare professional.

Safety Considerations in Special Populations

For those with liver or kidney problems, hydroxyzine should be used with caution, and doses may need to be adjusted. During pregnancy, hydroxyzine should only be used if absolutely necessary, as there is a lack of extensive safety data. It’s also advised for those breastfeeding to avoid use due to the risk of adverse effects in the nursing infant.

Interactions with alcoholantidepressantssupplements, and other medications must be reviewed as hydroxyzine can enhance their sedative effects. Caution is recommended for patients on other central nervous system depressants or those with HIV on treatment due to potential interactions.

When taking hydroxyzine, patients should remain informed about these considerations and communicate regularly with their healthcare provider to ensure safe and effective use of the medication.

Additional Considerations

Before prescribing hydroxyzine for anxiety, health professionals consider several essential factors to ensure the safety and effectiveness of treatment. These include the potential for drug interactions, the management of dosing inconsistencies, and the incorporation of lifestyle adjustments and supportive therapies.

Drug Interactions and Contraindications

Hydroxyzine, widely used for its anxiolytic and antihistamine properties, can have drug interactions that may increase the risk of side effects, such as dizziness or impairment of the central nervous system. It is particularly important to avoid concomitant use with substances that depress CNS activity, such as alcohol, sedatives, and some antibiotics like certain macrolides. Patients should also be cautious of combining hydroxyzine with drugs that affect serotonin levels, like escitalopram, to prevent serotonin syndrome. It is crucial that individuals inform their doctor of all medications they are taking, including those for allergiesdermatitishives, and itching, as well as drugs administered pre- and post-surgery.

Managing Overdose and Missed Doses

In instances of overdose, immediate medical attention is vital to address symptoms such as excessive drowsiness and dizziness. If a dose is missed, patients should take it as soon as possible unless it’s near the time for the next dose. Doubling up doses is discouraged to avoid potential overdose. Physicians caution that although hydroxyzine is not classified as a controlled substance, it should be used responsibly to prevent dependence and to ensure optimal sleep quality, especially for patients with insomnia. In the case of a possible overdose, call 911 or head to the emergency room.

Lifestyle and Supportive Therapies in Conjunction with Hydroxyzine

Lifestyle changes and supportive therapies like improved sleep hygiene and activities such as cognitive-behavioural therapy (CBT) or mindfulness can help complement hydroxyzine or other medication treatments of anxiety and potentially improve symptoms of anxiety and insomnia. For treatment of the physical manifestations of anxiety (shakiness, sweating etc), medications like beta blockers and mindfulness and meditation techniques can be helpful as well. A treatment plan should always be discussed with your doctor based upon your unique and specific symptoms.

All in all, then, hydroxyzine can be seen as an alternative for treating anxiety, especially when traditional antidepressants or other treatments cannot be used or have undesirable effects. The fact that hydroxyzine can alleviate anxiety symptoms can supported by the fact that it doesn’t seem to have much abuse potential and is relatively safe to use in most people. As such, hydroxyzine could be a valuable addition to the treatment armamentarium against anxiety. However, it’s important to note that drowsiness and a general reduction in vigilance that can be seen with hydroxyzine – especially at higher doses – and this could be problematic if one is responsible for driving, operating machinery, or any task that requires vigilance. Further studies are needed to examine the effects of long-term use and determine ideal dosing strategies in the years to come so that its key benefits can be balanced against its potential risks, thereby ensuring that hydroxyzine remains a safe and useful option for treating anxiety.
