Hooikoortstabletten Loratadine Trekpleister (Loratadine)

Hooikoortstabletten Loratadine Trekpleister is used to manage common allergic conditions. It helps reduce symptoms caused by histamine release in the body.

• Relief of seasonal allergic rhinitis (hay fever)
• Treatment of perennial allergic rhinitis
• Management of acute urticaria (hives)
• Alleviation of itching and sneezing associated with allergic reactions
• Supportive therapy for mild allergic conjunctivitis when combined with other measures

• Loratadine acts as a selective peripheral H1‑receptor antagonist. By binding to H1 receptors on mast cells, basophils, and other target cells, it blocks the action of endogenous histamine released during allergic responses. This inhibition prevents the cascade of intracellular events that lead to vasodilation, increased vascular permeability, and sensory nerve stimulation, thereby reducing typical allergy symptoms such as itching, swelling, and rhinorrhea.

Loratadine is generally well tolerated, but some users may experience adverse reactions.

Common

• Headache
• Dry mouth
• Mild drowsiness or fatigue
• Nausea or abdominal discomfort
• Nasal congestion

Serious

• Severe skin rash or Stevens‑Johnson syndrome
• Anaphylactic reaction (difficulty breathing, swelling of face or throat)
• Hepatotoxicity (jaundice, elevated liver enzymes)
• Cardiac arrhythmias (rare)
• Blood dyscrasias such as neutropenia

Before using Hooikoortstabletten Loratadine Trekpleister, consider the following safety points.

• Use with caution in patients with liver impairment; dose adjustment may be required.
• Not recommended for children under 12 years without medical guidance.
• Pregnant or breastfeeding individuals should consult a healthcare professional.
• Avoid concurrent use with other antihistamines to reduce risk of additive sedation.
• Discontinue use and seek medical attention if signs of a severe allergic reaction occur.
• Keep out of reach of children to prevent accidental ingestion.

Loratadine may interact with several medicines; awareness can help prevent reduced efficacy or increased toxicity.

Avoid

• Strong CYP3A4 inhibitors (e.g., ketoconazole, erythromycin) that can raise loratadine plasma levels.
• Alcohol or central nervous system depressants that may increase sedation.

Use with caution

• Other antihistamines or sedating medications (may enhance drowsiness).
• Antifungal agents such as itraconazole (moderate interaction).
• Certain antidepressants (e.g., fluoxetine) that affect metabolism.
• Herbal supplements like St. John's wort (may reduce effectiveness).
