Key Differences
Claritin, generically known as loratadine, is an over-the-counter medication primarily used to treat allergy symptoms like sneezing, itching, and watery eyes. Claritin-D, on the other hand, includes the same antihistamine properties of Claritin but adds a decongestant called pseudoephedrine.
The primary function of Claritin is to block histamines, which are chemicals in the body that cause allergy symptoms. Claritin-D not only blocks histamines but also helps reduce nasal congestion and sinus pressure due to its decongestant component.
Claritin is known for its non-drowsy formula, making it suitable for daytime use without causing sleepiness. Claritin-D, while also generally non-drowsy, may cause sleeplessness or nervousness in some people due to the pseudoephedrine.
Claritin is typically taken once daily for relief from allergies. Claritin-D may require a government-issued ID for purchase in some regions due to the pseudoephedrine content, which can be misused to manufacture illegal drugs.
Regarding side effects, Claritin is less likely to cause drowsiness compared to other antihistamines. Claritin-D can have additional side effects like increased heart rate or blood pressure due to the decongestant.
