Generic: Loratadine

Reviewed by Dr. Younghun ChoLast reviewed April 24, 2026

Generally yes, Claritin 24 Hour Allergy Relief Loratadine Tablets 10mg are safe for most adults and children aged 6 and older when used as directed. It is a non-drowsy antihistamine that effectively relieves common allergy symptoms like sneezing, runny nose, and itchy eyes or throat without causing significant sedation for most users.

Who Should Avoid or Consult First

  • Children under 6 years old (for the 10mg tablet formulation)
  • People with severe liver or kidney disease should consult a doctor before use, as dose adjustments may be needed
  • Pregnant or breastfeeding women should talk to their doctor before taking Claritin

Common Side Effects

  • Headache — reported in a small percentage of users
  • Dry mouth
  • Fatigue or tiredness — less common than with older antihistamines, but can still occur in some individuals
  • Nervousness or restlessness
  • Stomach pain or diarrhea

Interactions to Watch For

Ketoconazole, Erythromycin, or Cimetidine

These medications can increase the amount of loratadine in your body, potentially leading to more side effects, though this is usually not a major concern.

Alcohol or other sedating medications

While Claritin is generally non-drowsy, combining it with alcohol or other drugs that cause drowsiness could increase sedation for some individuals.
