Rupatadine Fumarate


Rupatadine is indicated for the symptomatic treatment of Seasonal & Perennial Allergic Rhinitis and Urticaria.


Rupatadine is a long-acting, non-sedative antagonist of histamine H1-receptors. It also antagonizes the platelet activating factor (PAF). Both histamine and PAF cause broncho constriction which leads to an increase in the vascular permeability and act as a mediator in the inflammatory process. With the dual mode of action, Rupatadine shows better therapeutic effect than an isolated antihistamine. Rupatadine possesses other anti allergic properties such as the inhibition of the degranulation of mast cells induced by immunological and non immunological stimuli and inhibition of the release of cytokines, particularly of the tumor necrosis factor alpha (TNF α) in human mastocytes and monocytes.

Dosage & Administration

Adults and adolescents (over 12 years): The recommended dose is 10 mg once a day. Rupatadine may be taken with or without food.

Children aged 2 to 11 years:
  • Children weighing 25 kg or more: 1 teaspoonful (5 ml) of the oral solution once daily with or without food.
  • Children weighing equal or more than 10 kg to less than 25 kg: 1/2 teaspoonful (2.5 ml) oral solution once daily with or without food.


With medicine: The concomitant administration of Rupatadine 20 mg and ketoconazole or erythromycin increases the systemic exposure. Rupatadine should be used with caution when it is administered concomitantly with these drug substances and other inhibitors of the isozyme CYP3A4.
