Formula Information

A small arrow pointing down

Hydroxyzine dihydrochloride 25 mg suppositories offer an alternative route of administration for patients requiring antihistamine therapy. As an antihistamine, hydroxyzine is commonly used to treat symptoms associated with allergies, such as itching, hives, and rashes. It also has anxiolytic properties, making it effective in managing anxiety and tension.

The suppository form is particularly beneficial for patients who have difficulty swallowing pills, are experiencing nausea or vomiting, or require rapid absorption of the medication. When inserted rectally, the suppository dissolves and allows hydroxyzine to be absorbed through the rectal mucosa directly into the bloodstream, potentially providing quicker onset of action compared to oral administration.

For prescribers, compounding hydroxyzine dihydrochloride into a suppository form allows for personalized patient care. It ensures that patients with unique needs or limitations can still receive the therapeutic benefits of hydroxyzine. This customized approach can improve compliance and overall treatment outcomes, especially in pediatric, geriatric, or palliative care settings where alternative dosing forms are often necessary.

Patients using hydroxyzine suppositories should follow their healthcare provider's instructions carefully. Proper insertion technique is important for optimal absorption and effectiveness. Common side effects may include drowsiness, dry mouth, blurred vision, or dizziness. Patients should be cautioned about engaging in activities that require mental alertness, such as driving or operating heavy machinery, until they know how the medication affects them.

Drug Interactions

A small arrow pointing down

Hydroxyzine Dihydrochloride 25 mg suppositories are a solid dosage form designed for insertion into a body cavity, such as the rectum or vagina, where they dissolve or melt to release medication for local or systemic absorption. This formulation is used to treat various conditions, including anxiety, nausea, vomiting, allergies, and as a sedative for premedication before surgery. While effective, it is crucial to be aware of potential drug interactions that may affect the safety and efficacy of hydroxyzine suppositories.

Hydroxyzine is an antihistamine with anticholinergic and sedative properties, which can interact with other medications that have similar effects. Concomitant use with other central nervous system (CNS) depressants, such as benzodiazepines, opioids, or alcohol, can enhance the sedative effects, leading to increased drowsiness, dizziness, and risk of respiratory depression. Patients should be advised to avoid or limit the use of alcohol and consult their healthcare provider before using other CNS depressants.

Anticholinergic drugs, including certain antidepressants, antipsychotics, and medications for Parkinson's disease, may interact with hydroxyzine by exacerbating anticholinergic side effects such as dry mouth, constipation, urinary retention, and blurred vision. Patients should be monitored for these effects, and dose adjustments may be necessary.

Hydroxyzine may also interact with medications that prolong the QT interval, such as certain antiarrhythmics, antibiotics, and antipsychotics. This interaction can increase the risk of serious cardiac arrhythmias, including Torsades de Pointes. Patients with a history of cardiac conditions or those taking other QT-prolonging drugs should be closely monitored, and alternative treatments should be considered if necessary.

Additionally, hydroxyzine can interfere with skin allergy tests, as it may suppress the wheal and flare response. It is recommended to discontinue hydroxyzine at least 72 hours before undergoing such tests to avoid false-negative results.

Patients and prescribers should be aware of these potential interactions and take appropriate precautions. It is essential to review the patient's current medication list, including over-the-counter drugs and supplements, to identify any possible interactions.

How Does it Work

A small arrow pointing down

Hydroxyzine Dihydrochloride 25 mg suppositories are a specialized formulation designed to deliver medication through insertion into a body cavity, typically the rectum. This solid dosage form is engineered to dissolve or melt at body temperature, facilitating the release of hydroxyzine for absorption. Hydroxyzine is an antihistamine with anticholinergic and sedative properties, commonly used to manage symptoms of anxiety, tension, and allergic reactions, as well as to induce sedation prior to medical procedures.

Upon insertion, the suppository begins to dissolve or melt, allowing the hydroxyzine to be absorbed through the mucous membranes of the rectum. This route of administration can be particularly beneficial for patients who are unable to take oral medications due to nausea, vomiting, or difficulty swallowing. The rectal mucosa provides a rich blood supply, enabling efficient systemic absorption of the medication, which can lead to rapid onset of action.

For patients experiencing anxiety or tension, hydroxyzine works by suppressing activity in certain areas of the central nervous system, providing a calming effect. Its antihistamine properties help alleviate symptoms of allergic reactions by blocking the action of histamine, a substance in the body that causes allergic symptoms. Additionally, the sedative effects of hydroxyzine can be useful in preparing patients for surgical or diagnostic procedures by reducing anxiety and inducing relaxation.

Prescribers may choose this formulation for patients who require a non-oral route of administration or for those who need a rapid onset of action. The rectal delivery system bypasses the gastrointestinal tract, reducing the risk of gastrointestinal side effects and first-pass metabolism in the liver, which can alter the effectiveness of the medication. This can be particularly advantageous in achieving the desired therapeutic effects with potentially lower doses.

It is important for both patients and prescribers to understand the proper administration technique for suppositories to ensure optimal absorption and effectiveness. Patients should be advised to store the suppositories in a cool place to prevent melting and to follow specific instructions for insertion.

Other Uses

A small arrow pointing down

Hydroxyzine Dihydrochloride 25 mg suppositories are primarily used for their antihistamine and anxiolytic properties, often prescribed for the treatment of anxiety, nausea, and allergic reactions. However, this formulation can also be considered for other uses due to its pharmacological profile. One potential off-label use is for the management of pruritus, or severe itching, which can be associated with various dermatological conditions or systemic diseases. The rectal administration of hydroxyzine can be particularly beneficial for patients who have difficulty swallowing oral medications or for those who experience gastrointestinal disturbances that may affect the absorption of oral formulations.

Additionally, hydroxyzine suppositories may be utilized in palliative care settings to help manage symptoms such as anxiety and agitation in patients who are unable to take medications orally. The systemic absorption through rectal administration can provide a calming effect, which is valuable in end-of-life care where comfort is a priority. Furthermore, hydroxyzine's sedative properties can be advantageous in preoperative or postoperative settings to help reduce anxiety and induce sedation, especially in patients who are unable to tolerate oral medications due to nausea or vomiting.

For prescribers, it is important to consider the patient's overall health status, potential drug interactions, and specific needs when prescribing hydroxyzine suppositories for off-label uses. Patients should be informed about the potential side effects, such as drowsiness, dry mouth, and dizziness, and advised to avoid activities that require mental alertness until they know how the medication affects them. As with any medication, the benefits and risks should be carefully weighed, and the decision to use hydroxyzine suppositories for off-label purposes should be based on clinical judgment and individual patient circumstances.
