Hydroxyzine Withdrawal Symptoms: An Overview
Introduction to Hydroxyzine and Its Uses
Hydroxyzine is an antihistamine commonly used to treat anxiety, nausea, and allergies. It is also sometimes used as a sedative before surgery. While hydroxyzine is generally considered safe, there are instances where withdrawal symptoms can occur, particularly after long-term use.
Hydroxyzine and Opioid Withdrawal
Reduction of Opioid Withdrawal Symptoms
Research has shown that hydroxyzine can be effective in reducing the severity of opioid withdrawal symptoms. In a study involving healthy male volunteers, the co-administration of hydroxyzine with a 5-HT3 receptor antagonist (palonosetron) significantly reduced the objective signs of opioid withdrawal induced by naloxone after morphine administration 1. This suggests that hydroxyzine may enhance the effectiveness of treatments aimed at alleviating opioid withdrawal symptoms.
Hydroxyzine in Benzodiazepine Withdrawal
Efficacy in Lorazepam Withdrawal
Hydroxyzine has also been studied for its role in benzodiazepine withdrawal. In a controlled study involving patients with generalized anxiety who were long-term users of lorazepam, hydroxyzine was used to support the withdrawal process. The study found that hydroxyzine, whether administered abruptly or progressively, helped reduce withdrawal symptoms and anxiety levels significantly 2. Patients who received hydroxyzine reported fewer withdrawal symptoms and side effects compared to those who received a placebo.
Hydroxyzine and Generalized Anxiety Disorder (GAD)
Anxiety Reduction and Withdrawal Symptoms
In a study focused on patients with generalized anxiety disorder, hydroxyzine was found to be effective in reducing anxiety symptoms over a four-week period. Importantly, the study noted that there were no significant withdrawal symptoms after abrupt discontinuation of hydroxyzine 3. This indicates that hydroxyzine can be a safe option for managing anxiety without the risk of severe withdrawal symptoms.
Hydroxyzine in Alcohol Withdrawal
Comparison with Other Treatments
Hydroxyzine has also been evaluated for its effectiveness in treating acute alcohol withdrawal symptoms. In a study comparing hydroxyzine with other drugs like chlordiazepoxide and chlorpromazine, hydroxyzine was found to be less effective in preventing severe withdrawal symptoms such as delirium tremens and convulsions 45. This suggests that while hydroxyzine may offer some benefits, it may not be the best option for managing severe alcohol withdrawal symptoms.
Neonatal Withdrawal Symptoms
Case Report on Neonatal Withdrawal
A case report highlighted the potential for neonatal withdrawal symptoms associated with maternal hydroxyzine use during late pregnancy. The newborn exhibited neurological symptoms, which were attributed to hydroxyzine withdrawal, confirmed by plasma concentration measurements 6. This underscores the need for caution when prescribing hydroxyzine to pregnant women.
Conclusion
Hydroxyzine is a versatile antihistamine with applications in treating anxiety, opioid withdrawal, and as a sedative. While it is generally safe, there are instances where withdrawal symptoms can occur, particularly in neonates and long-term users. Studies suggest that hydroxyzine can effectively reduce withdrawal symptoms in opioid and benzodiazepine users, but it may not be the best option for severe alcohol withdrawal. Clinicians should be aware of these potential withdrawal symptoms and monitor patients accordingly.
