What is the relationship?
Claritin and Furosemide are different things: Claritin is a branded medication whose active ingredient is Loratadine (in the Allergy and Antihistamines class), whereas Furosemide is in the Loop diuretic class. They belong to different therapeutic classes and are chosen for different indications.
When Claritin is used
Claritin is approved in adults and children for the treatment of seasonal and perennial allergic rhinitis and chronic idiopathic urticaria.

Mechanisms compared
Claritin: Loratadine selectively blocks peripheral H1 histamine receptors, antagonising histamine effects during allergic reactions. Furosemide: Furosemide acts on the thick ascending limb of the loop of Henle in the kidney, where it inhibits the Na+/K+/2Cl- co-transporter (NKCC2).
When the comparison makes sense
