One-A-Day Allergy Relief (Loratadine)

Loratadine is an antihistamine that provides symptom relief across several allergy‑related conditions.

• Seasonal allergic rhinitis: Reduces sneezing, nasal congestion, and itchy watery eyes.
• Chronic urticaria: Diminishes the frequency and severity of hives.
• Allergic conjunctivitis: Alleviates eye itching and redness.

• Loratadine selectively blocks peripheral H1 histamine receptors, preventing histamine‑induced vasodilation, increased vascular permeability, and sensory nerve stimulation. This antagonism reduces the typical signs of allergic inflammation without readily crossing the blood‑brain barrier, limiting central nervous system effects.

Adverse reactions to loratadine are generally mild and reversible.

Common Side Effects

• Headache: Mild to moderate intensity.
• Dry mouth: Transient sensation of oral dryness.
• Fatigue: Low‑grade tiredness not interfering with daily activities.
• Nausea: Occasional mild stomach upset.
• Drowsiness (rare for loratadeine): Slight sleepiness in a small subset of patients.

Serious or Rare Side Effects

• Stevens‑Stevenson: Severe skin rash with blistering and systemic involvement.
• Anaphylaxis: Acute, potentially life‑threatening allergic reaction.
• Hepatotoxicity: Elevated liver enzymes indicating liver stress.
• Cardiac arrhythmia: Irregular heartbeat reported in isolated cases.
