Hydroxyzine is an antihistamine that reduces the effects of the body’s natural chemical called histamine, which can cause sensations like itching or the formation of hives on the skin. Hydroxyzine is used to treat allergic skin reactions such as hives or contact dermatitis. It is also applied in the treatment of various allergic skin conditions, including hives and contact dermatitis.
How should I take hydroxyzine?
Follow your doctor’s instructions precisely when taking hydroxyzine. Adhere to all the guidelines provided on your prescription label. Your doctor may occasionally adjust your dosage. Avoid using this medication in amounts that are larger or smaller than advised, and do not extend its use beyond the recommended duration.
Before measuring a dose, make sure to shake the oral suspension (liquid) thoroughly. Use the provided dosing syringe, a designated dose-measuring spoon, or a medicine cup to measure the liquid medicine. If you don’t have a suitable measuring tool, consult your pharmacist to obtain one.
How long does hydroxyzine stay in your system?
Hydroxyzine is a commonly used antihistamine for the treatment of allergies, anxiety, and certain other medical conditions. The length of time hydroxyzine remains in your system can vary based on factors such as your metabolism, dosage, frequency of use, and individual variations.
The elimination half-life of hydroxyzine can range from approximately 3 to 14 hours. This indicates that it takes this amount of time for the concentration of hydroxyzine in your bloodstream to decrease by half. On average, it may take about 1 to 2 days for hydroxyzine to be mostly eliminated from your system.
However, it’s essential to recognize that individual differences can have a significant impact. Some individuals may metabolize the drug more quickly or slowly than others. Additionally, the duration of its effects (such as sedation or antihistamine action) might differ from the time it takes for the drug to be completely cleared from the body.
If you have concerns about the duration of hydroxyzine in your system, particularly if you plan to take other medications or have underlying medical conditions, it is advisable to consult a healthcare professional for personalized advice tailored to your specific situation.
How hydroxyzine works
Hydroxyzine functions by attaching itself to histamine receptors found in the brain. Histamine is a protein with various roles in the body, including assisting the immune system in fighting infections. However, excessive or unnecessary release of histamine can result in issues like itching. Through its action of blocking histamine, hydroxyzine effectively reduces itching.
The mechanism by which hydroxyzine induces sedation and relieves anxiety is believed to be connected to its binding to brain histamine receptors. This is because brain histamine plays a role in promoting wakefulness. By binding to these receptors, hydroxyzine can counteract histamine’s wakefulness-promoting effect, leading to sedation and a reduction in anxiety.
What happens if I miss a dose?
If you happen to forget a dose of your medication, take it as soon as you remember. However, if your next scheduled dose is approaching, it’s best to skip the missed dose. Avoid taking extra medication to make up for the dose you missed.
What happens if I overdose?
If there is a need for urgent medical assistance or if you require help, please contact the Poison Help line immediately at 1-800-222-1222.
Signs of an overdose may include severe drowsiness, nausea, vomiting, uncontrollable muscle twitches, or seizures. It’s crucial to seek prompt medical attention if you suspect an overdose or experience these symptoms.
What to avoid
This medication can potentially impact your cognitive abilities and responsiveness. It is important to exercise caution when participating in activities like driving or tasks that require vigilance.
Combining alcohol with this medication may result in adverse effects and is generally not recommended. It’s advisable to avoid alcohol while taking this medication to ensure your safety and well-being.
Hydroxyzine side effects
If you display signs of an allergic reaction to hydroxyzine, such as hives, difficulty breathing, or swelling of the face, lips, tongue, or throat, it is crucial to seek immediate medical assistance.
In rare instances, hydroxyzine may cause a severe skin reaction. If you experience sudden skin redness, a rash that spreads and results in white or yellow pustules, blistering, or peeling, discontinue its use and promptly contact your doctor.
Stop using hydroxyzine and get in touch with your doctor immediately if you encounter:
- Rapid or pounding heartbeats.
- A headache accompanied by chest pain.
- Severe dizziness or fainting.
- Seizures (convulsions).
These symptoms require immediate medical attention to ensure your safety and appropriate management of any potential complications.
Before starting hydroxyzine oral tablet treatment, it is essential to consult your doctor regarding your medical history. Several medical conditions and factors could influence the suitability of hydroxyzine oral tablets for your use. These considerations include:
- Age: Older individuals should exercise caution when using hydroxyzine, as they are at an increased risk of experiencing side effects. If hydroxyzine is necessary for older adults, a lower dosage is often prescribed, along with careful monitoring by their doctor. Older individuals are more susceptible to side effects such as confusion, constipation, and dry mouth from hydroxyzine.
- Convulsions or Seizures: While not commonly reported in clinical trials, some individuals have experienced seizures after using hydroxyzine. If you have a history of convulsions or seizures or are at a higher risk for such conditions, it’s advisable to discuss hydroxyzine usage with your doctor.
- Dementia: Hydroxyzine can lead to side effects like confusion and difficulty concentrating, especially in individuals with dementia. If you have dementia, your doctor can assess the safety of hydroxyzine for your specific situation.
- Heart Problems: Hydroxyzine has the potential to affect the QT interval of your heart rhythm. Individuals with existing heart issues, including those already taking medication for heart rhythm management, face an elevated risk of this side effect when using hydroxyzine. Before starting hydroxyzine, ensure your doctor is informed about any heart problems you might have so they can establish the safest course of treatment.
- Kidney or Liver Problems: People with kidney or liver problems should receive a reduced hydroxyzine dosage. This is because the kidneys and liver are involved in metabolizing hydroxyzine. Impaired kidney or liver function could hinder the breakdown of the medication, increasing the risk of side effects. If you have kidney or liver issues, your doctor can determine whether hydroxyzine is suitable for you.
- Low Blood Pressure: Hydroxyzine can lead to low blood pressure. If you already have this condition, your risk of experiencing low blood pressure as a side effect is higher. Discuss all medical conditions, including low blood pressure, with your doctor before starting hydroxyzine treatment.
- Allergic Reaction: If you’ve had a previous allergic reaction to hydroxyzine or any of its components, it’s advisable to avoid using hydroxyzine oral tablets. Consult your doctor to explore alternative medication options.
- Pregnancy: Hydroxyzine use during pregnancy is generally not considered safe. Refer to the “Hydroxyzine and Pregnancy” section for more details.
- Breastfeeding: While taking hydroxyzine, breastfeeding is not recommended due to the potential transfer of the medication to the infant through breast milk.
Discuss your medical history and any relevant factors with your doctor to ensure that hydroxyzine is safe and appropriate for your specific situation.
Hydroxyzine is a versatile medication with dual actions. As an antihistamine, it effectively counteracts symptoms related to histamine, providing relief from itching and allergic skin reactions. Furthermore, its interaction with histamine receptors in the brain results in sedative effects, making it valuable for the management of anxiety and tension.
However, careful consideration is necessary when starting hydroxyzine use, particularly in older individuals and those with specific medical conditions such as convulsions, dementia, heart problems, kidney or liver issues, low blood pressure, and allergies to the drug. These factors should be thoroughly evaluated by a healthcare professional to determine the suitability and safety of hydroxyzine for each individual’s unique circumstances.
