Effectiveness

How Hydroxyzine Pamoate Affects Patients

Hydroxyzine helps reduce symptoms of allergies such as itching, and can also be used as a sedative and anti-nausea medication. It usually starts working within 15-60 minutes and can last for 4-6 hours. It may increase the effects of other medicines that cause drowsiness, so patients should be carefully monitored after receiving general anesthesia. Hydroxyzine can also interfere with the heart's electrical activity, which can lead to serious heart problems, so it should be used cautiously in those with an increased risk of such problems.

How Hydroxyzine Pamoate works in the body

Hydroxyzine is a medicine used to treat allergic reactions. It works by blocking the histamine H1 receptor, which is responsible for causing allergic symptoms like itching, sneezing, and watery eyes. Hydroxyzine also has sedative and anti-nausea effects, which are thought to come from blocking other receptors in the body.

Hydroxyzine Pamoate Toxicity & Overdose Risk

The lowest toxic dose of hydroxyzine in rats has been found to be 840 mg/kg and 400 mg/kg in mice. Symptoms of overdose include excessive sedation, seizures, confusion, nausea, and vomiting. Treatment involves inducing vomiting and providing general supportive care. Low blood pressure may be treated with intravenous fluids, and caffeine and sodium benzoate can be administered to reduce the effects of CNS depressants. Dialysis is unlikely to help with hydroxyzine overdose.

Hydroxyzine Pamoate for Inducing of a Relaxed Easy State

I was prescribed this after being taken off of clonazepam, which actually worked for me. This medication does nothing in comparison and the withdrawal from clonazepam has been incredibly difficult. I haven't slept more than an hour or two since stopping that medicine, and my anxiety is through the roof. Doctors are quick to prescribe this as a replacement for something that actually works because they're afraid of addiction, but all this has done is make me miserable.

Patient Q&A Section about hydroxyzine pamoate

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is hydroxyzine pamoate used for?

"Hydroxyzine is used to treat itching resulting from allergies. By blocking histamine, it functions as an antihistamine to alleviate allergic reactions."

Answered by AI

Is hydroxyzine pamoate the same as Xanax?

"These drugs work by different mechanisms, but both have anti-anxiety effects.

The drugs Vistaril and Xanax are both used to treat anxiety, though they work via different mechanisms. Vistaril is an antihistamine with drying and sedative properties, while Xanax is a benzodiazepine. Though their means of anxious relief differ, both drugs are effective."

Answered by AI

Is hydroxyzine pamoate good for anxiety?

"Vistaril is used as a short-term treatment for anxiety symptoms or as an alternative to habit-forming anxiety medications such as benzodiazepines. It is also prescribed as an antihistamine to treat skin allergies, so it can be a good choice for people who have both allergies and anxiety."

Answered by AI

Is hydroxyzine pamoate a sleeping pill?

"Hydroxyzine is an antihistamine that is approved for the treatment of anxiety. However, it is also used to treat difficulty sleeping, nausea, vomiting, itching, skin rash, and allergies."

Sleep and Dreaming Practices for Anxiety

18+
All Sexes
Evanston, IL

People spend approximately one-third of their lives asleep, yet sleep is often underused as an opportunity to support psychological well-being. Contemplative traditions, including Tibetan Dream Yoga, have developed practices that use waking imagination and lucid dreaming to explore perception, awareness, and habitual patterns of thinking. Recent advances in sleep monitoring, dream communication, and lucid dream induction now make it possible to study these practices using scientific methods. This study is a randomized controlled trial designed to examine the feasibility and effects of a Dream-Yoga-inspired intervention compared with an active control condition. The intervention combines waking and dreaming practices that are adapted for individuals without prior experience and delivered using virtual reality-based training and home sleep technology. The program is designed to be scalable and culturally neutral, without requiring prior knowledge of contemplative or religious traditions. The primary goals of the study are to characterize sleep and waking neurophysiology associated with Dream-Yoga-inspired practices and to evaluate whether participation is associated with changes in sleep-related brain activity and cognitive processes. Outcomes include measures of lucid dreaming, sleep physiology, and waking cognitive and perceptual processes. Anxiety will be assessed as an exploratory outcome to examine whether participation may be associated with changes in emotional experience. This study is not designed to provide treatment for anxiety or other clinical conditions. Results from this study will help inform the development of scalable sleep-based mental training approaches and guide future research on the use of dreaming and sleep practices to support psychological health and well-being

Audio-Based Therapy for Anxiety in Psoriasis

18+
All Sexes
San Francisco, CA

Anxiety in psoriasis is associated with impaired quality of life, and the prevalence of anxiety symptoms in psoriatic populations is approximately 34% and anxiety disorders up to 16%. Many experts recommend routine screening, referral, and interventions for anxiety in psoriasis; however, many barriers inhibit access to mental health resources and proper management. To our knowledge, there is a lack of easily accessible interventions that manage anxiety. Audio-based therapy offers convenient and effective interventions that show reduced anxiety in published, randomized studies and is a promising management for psoriasis patients. This study will evaluate the effects of audio therapy in patients with psoriasis and measure changes in overall symptoms.

BEAR Program for Suicidal Thoughts

18 - 75
Female
Stanford, CA

The current study aims to test the feasibility of a new form of group therapy for women who have a history of interpersonal trauma and current suicidal ideation. The Building Empowerment and Resilience (BEAR) Therapeutic group has been adapted for women who have experienced trauma and have current suicidal ideation. It incorporates psychological skills, psychoeducation about trauma and gender-based violence, and physical self-defense training, all within a therapeutic process. It will be implemented with women who have experienced interpersonal trauma (physical, sexual, or emotional abuse/neglect) and experience various mental health difficulties, including suicidal ideation. We aim to assess the feasibility to recruit and implement the BEAR group. Our ultimate aim is to assess whether the program can effect self-efficacy and suicidal ideation.

Psilocybin Therapy for Anxiety and Depression in Cancer

18 - 85
All Sexes
Seattle, WA

This phase II trial tests the safety, side effects and how well group retreat psilocybin therapy works for the treatment of anxiety and depression in patients with solid tumors that have spread from where they first started (primary site) to other places in the body (metastatic) or with hematologic cancers for which no treatment is currently available (incurable). For patients with metastatic, incurable cancer, unrelieved anxiety and existential distress can cause profound suffering. Psilocybin therapy can relieve anxiety and existential distress by disrupting patterns of thinking that contribute to anxiety and depression. Psilocybin is a substance being studied in the treatment of anxiety or depression in patients with cancer. In this study, a pharmaceutical grade of psilocybin will be used that has been approved by the FDA for research, provided by Filament Health. Psilocybin acts on the brain by resetting the brain's activity and increasing connections between brain regions, particularly those involved in mood regulation and self-perception. In this study psilocybin is combined with structured discussions and reflections that enable patients to have new insights about their situation. In a prior study, group retreat psilocybin therapy was proven to be safe and this study tests a refined dosing regimen for symptoms of anxiety and depression in patients with metastatic solid tumors or incurable hematologic malignancies.

Pine Ridge, SD

The goal of this open pilot trial (OPT) is to develop a Lakota-adapted Family Acceptance Project (LFAP) for Indigenous 2SLGBTQ+ youth and their caregivers. The OPT is specifically focused on acceptability, feasibility, and safety of programming and research protocols. The investigators will also examine pre- to post- changes on outcomes for the sole purposes of making sure scores on measures are changing in the hypothesized direction (e.g., depression scores are going from moderate to minimal as opposed to no change or depression scores increasing). Once enrolled in the study, participants complete a baseline survey. Then participants will engage in LFAP which is an 8-session group intervention; sessions will be scheduled once a week for eight weeks (at 2 hours per session). Participants will complete survey instruments before and immediately after the program sessions, in addition to post-program surveys and an exit interview.
