Overview
Clarinase 24hr Tablet is a 24-hour repeat-action tablet combining loratadine 5mg and pseudoephedrine sulfate 120mg, used to relieve the symptoms of allergic rhinitis – sneezing, a runny or itchy nose, and itchy/watery eyes – together with the nasal and sinus congestion that often accompanies it.
Loratadine relieves allergy symptoms by blocking histamine, the substance the body releases during an allergic reaction, while pseudoephedrine narrows swollen blood vessels in the nasal passages to relieve congestion; the repeat-action formulation releases the decongestant gradually so that both effects last for up to 24 hours from a single tablet.
How it Works
Loratadine is a second-generation antihistamine that selectively blocks peripheral H1 histamine receptors, reducing sneezing, itching, and nasal/eye discharge without significant sedation, while pseudoephedrine is a sympathomimetic decongestant that constricts dilated nasal blood vessels, reducing swelling of the nasal lining and relieving congestion.
Directions for Use
Take Clarinase 24hr Tablet once daily, with or without food, swallowing the tablet whole with water – do not crush, chew, or split the tablet, as this is a repeat-action formulation designed to release the decongestant gradually over 24 hours.
Dosage
The usual dose of Clarinase 24hr Tablet is one tablet once daily, providing symptom relief for up to 24 hours. Your doctor or pharmacist will advise on how long you can safely use this combination product, as the decongestant component is generally intended for short-term relief rather than continuous long-term use.
Shelf Life

Drug / Food Interactions

- Pseudoephedrine may reduce the blood-pressure-lowering effect of antihypertensive medicines
- Alcohol or other CNS depressants may modestly increase drowsiness, though loratadine itself is largely non-sedating
