Flonase vs Claritin – Which Is The Best Allergy Medicine?

Flonase vs Claritin - Which Is The Best Allergy Medicine

Allergies occur when your immune system reacts to a food which doesn’t cause a reaction in most people or a foreign substance (like – bee venom, pollen, or pet dander).

Allergies are very common, and over 50 million people in the United States suffer from allergies.

Symptoms

Symptoms may include one or more of the following:

  • odd taste in the mouth;
  • hives (itchy areas on the skin);
  • slight, dry cough;
  • eczema flare (a persistent dry rash);
  • sneezing;
  • redness of the skin, especially around the mouth or eyes;
  • nasal congestion or a runny nose;
  • stomach pain;
  • diarrhea;
  • vomiting;
  • nausea;
  • itchy mouth.

An allergist can properly diagnose your condition and prescribe an allergy treatment to help you feel better and live better.

Below Is A Comparison Of Two Allergy Medications

Flonase (generic name – fluticasone propionate) is in a class of medications called corticosteroids. This synthetic corticosteroid has 18-fold higher affinity for the corticosteroid receptor compared with the reference standard for corticosteroid potency (dexamethasone).

Claritin (generic name – loratadine) is an over-the-counter antihistamine medication which was first approved by the US Food and Drug Administration in 1993. It belongs to a family of drugs called histamine H1 antagonists and nasal decongestants.

Its structure resembles that of the tricyclic antidepressants and it is a derivative of azatadine.

It comes in two versions: Claritin and Claritin-D (contains loratadine plus pseudoephedrine – a sympathomimetic medication of the amphetamine and phenethylamine chemical classes). Both versions come in OTC versions as well as by prescription.

Claritin

It is used to treat the symptoms of allergies, such as watery eyes, sneezing, and runny nose. Moreover, this antihistamine is used to treat skin hives and itching in sufferers with chronic skin reactions.

You should not take Claritin if you are allergic to loratadine or to other ingredients in this product. In addition, Claritin may contain phenylalanine, a precursor for catecholamines including dopamine, epinephrine, tyramine, and norepinephrine. Talk to your healthcare professional before using this medicine if you have phenylketonuria (an inherited disorder which increases the levels of phenylalanine in the blood).

Conclusion – Flonase vs Claritin

Flonase (fluticasone propionate) belongs to the class of medications called corticosteroids. Fluticasone propionate is used to treat seasonal allergic rhinitis, including perennial rhinitis and hay fever.

Claritin (loratadine) is an antihistamine which works by blocking histamine, a substance in the human body which causes allergic symptoms. This antihistamine is used to relieve hay fever and allergy symptoms, including watery eyes, sneezing, and runny nose.

According to a March 4, 2002 study which was done at the University of Chicago and was presented at the 58th annual meeting of the American Academy of Allergy, Asthma and Immunology, the corticosteroid nasal spray Flonase is slightly more effective at controlling seasonal allergies than a combination of montelukast (brand name – Singulair) and loratadine (brand name – Claritin).

Can You Take Claritin And Flonase Together?

According to the data, there are no negative interactions between Claritin and Flonase. Therefore, both medications can be used, depending on the clinical symptoms and the response to treatment.
