The recommended adult dosage for cetirizine hydrochloride is 10 mg once daily. However, your doctor may prescribe 20 mg daily in certain cases, typically if a higher dose is needed for symptom relief. This higher dose should only be taken under the guidance of a physician.
Factors Influencing Dosage
Several factors influence the appropriate cetirizine dose. Kidney function plays a significant role; individuals with impaired kidney function may require a lower dose to prevent medication buildup. Similarly, age and overall health impact the body’s processing of the medication. Always inform your doctor about any existing health conditions or medications you are taking.
Administration and Potential Side Effects
Cetirizine hydrochloride 20 mg is typically administered orally, once daily, with or without food. Common side effects include drowsiness, dry mouth, and fatigue. While these are usually mild and temporary, inform your doctor if they persist or worsen. Severe reactions are rare but require immediate medical attention. Always follow your doctor’s instructions carefully regarding dosage and duration of treatment. Never exceed the prescribed dose.
When to Contact Your Doctor
Contact your doctor if your symptoms don’t improve after a few days of taking cetirizine, if you experience any unexpected side effects, or if your symptoms worsen. This information is for guidance only and does not replace professional medical advice. Always consult with your physician or pharmacist before starting any medication, especially if you have pre-existing health conditions or are taking other medications.
