This tablet should be administered when both the antihistaminic properties of Loratadine and the nasal decongestant activity of Pseudoephedrine are desired. This is indicated for the relief of the following symptoms due to hay fever or other upper respiratory allergies:
nasal congestion
runny nose
sneezing
itchy, watery eyes
itching of the nose or throat

sinus congestion and pressure

In general it is well tolerated. Clinical trial suggests a very low of adverse effects commonly reported is dry mouth, somnolence, insomnia, pharyngitis, dizziness, coughing, fatigue, nausea, nervousness, anorexia, dysmenorrheal and headache.

This tablet should generally be avoided in patients with hepatic insufficiency. Patients with renal insufficiency should be given a lower initial dose because they have reduced clearance of Loratadine and Pseudoephedrine. As because the doses of this fixed combination product cannot be individually titrated and hepatic insufficiency results in a reduced clearance of Loratadine to a much greater extent than Pseudoephedrine.
This tablet should be used with caution in patients with hypertension, diabetes mellitus, ischemic heart disease, increased intraocular pressure, hyperthyroidism, renal impairment, or with accompanying hypotension may be produced by sympathomimetic amines.

Loratadine is a non-sedative histamine H1-receptor antagonist with anti-allergic properties. Loratadine is a long acting tricyclic anti-histamine with selective peripheral H1-receptor antagonistic activity and no central sedative or anti-cholinergic effect.
Pseudoephedrine is an orally active sympathomimetic amine and exerts a decongestant action on the nasal mucosa. This is recognized as an effective agent for the relief of nasal congestion due to allergic rhinitis. It has nasal and bronchial decongestant activity. Pseudoephedrine is both an α-and β-adrenergic receptor agonist. It causes vasoconstriction via direct stimulation of α-adrenergic receptors of the respiratory mucosa. It also directly stimulates β-adrenergic receptors causing bronchial relaxation, increased heart rate and contractility.
