Claritin-D is used to treat seasonal allergies (hay fever), perennial allergies, and nasal congestion. It provides relief from symptoms such as sneezing, runny nose, itchy/watery eyes, and sinus pressure.
Loratadine blocks histamine H1 receptors to reduce allergic reactions, while pseudoephedrine constricts blood vessels in the nasal passages to decrease swelling and congestion. Together, they address both the histamine response and nasal stuffiness.
This medication may not be suitable for individuals with certain conditions including high blood pressure, heart disease, thyroid disorders, diabetes, or prostate issues. Pseudoephedrine may cause insomnia, nervousness, or increased heart rate. Patients should consult a healthcare provider before use if pregnant, breastfeeding, or taking other medications.
