Hooikoortstabletten Loratadine Etos (Loratadine)

Hooikoortstabletten Loratadine Etos is indicated for the temporary relief of symptoms associated with allergic conditions.

• Seasonal allergic rhinitis (hay fever) characterized by sneezing, nasal congestion, and itchy eyes.
• Perennial allergic rhinitis caused by indoor allergens such as dust mites or pet dander.
• Acute urticaria (hives) presenting with itchy, raised skin welts.
• Non‑sedating relief of itching and watery discharge due to allergic conjunctivitis.
• Symptomatic treatment of mild to moderate allergic reactions to insect bites or contact allergens.

• Loratadine acts as a selective peripheral histamine H1‑receptor antagonist. By binding to H1 receptors on mast cells, basophils, and vascular smooth muscle, it blocks the action of endogenous histamine released during allergic responses. This inhibition prevents the cascade that leads to vasodilation, increased vascular permeability, and sensory nerve stimulation, thereby reducing the typical signs of allergy such as itching, swelling, and rhinorrhea without crossing the blood‑brain barrier in significant amounts.

Like other antihistamines, loratadine may cause unwanted effects, most of which are mild and reversible.

Common

• Headache, often mild and transient.
• Dry mouth or mild throat irritation.
• Mild fatigue or occasional drowsiness, usually not impairing daily activities.
• Nausea, abdominal discomfort, or mild gastrointestinal upset.
• Dizziness or light‑headed feeling, usually brief.

Serious

• Severe skin reactions, including Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Rapid, irregular, or pounding heartbeat (arrhythmia) requiring medical attention.
• Swelling of the face, lips, tongue, or throat (angioedema) that may obstruct breathing.
• Difficulty breathing, wheezing, or bronchospasm indicative of a possible allergic reaction to the medication.

Before using Hooikoortstabletten Loratadine Etos, consider the following precautions to ensure safe and appropriate use.

• Verify that you are not allergic to loratadine or any other ingredients.
• Use with caution in patients with liver impairment, as metabolism may be reduced.
• Consult a healthcare professional before use during pregnancy or breastfeeding, because safety data are limited.
• Avoid driving or operating machinery if you experience drowsiness or visual disturbances.
• Keep the medication out of reach of children; accidental ingestion can cause adverse effects.
• Do not combine with other antihistamines or sedating medications without medical advice.
• Discontinue use and seek medical help if a rash, swelling, or breathing difficulty develops.

Loratadine can interact with certain medicines; awareness of these interactions helps prevent reduced efficacy or increased risk of side effects.

Avoid

• Strong CYP3A4 inhibitors such as ketoconazole, itraconazole, or clarithromycin, which can raise loratadine plasma levels.
• Other antihistamines or sedating agents that may increase drowsiness.

Use with caution

• Alcohol, which can enhance central nervous system effects.
• CNS depressants (e.g., benzodiazepines, opioids) that may potentiate sedation.
• Certain antidepressants (e.g., fluoxetine, paroxetine) that affect hepatic metabolism.
• Herbal supplements like St. John’s wort that induce CYP enzymes and may lower drug concentrations.
