Outdoor Allergy Symptoms
Hay fever, also known as outdoor allergies or pollen allergy, is one of the most common kinds of allergies. About 35 million Americans suffer from hay fever. It is caused by breathing in pollen from trees, grasses, and/or weeds that then cause an allergic reaction. This can result in classic allergy symptoms.
Clarinex-D is used to treat hay fever symptoms, including:
- Runny nose
- Itchy nose, ears, and throat
- Itchy, burning eyes
- Tearing/watering eyes
- Redness of eyes
- Nasal congestion.
For symptoms of hay fever, Clarinex-D can be used in adults and adolescents 12 years of age and older.
How Does Clarinex-D Work?When you come into contact with something you're allergic to, a chain reaction begins inside your body. During this chain reaction, special cells release powerful chemicals. Some of these chemicals can trigger swelling of the nasal passages, leading to nasal congestion (a "stuffy" nose). Other chemicals, such as histamine, can cause sneezing, itching, and irritation.
Clarinex-D is a combination medication of desloratadine and pseudoephedrine sulfate. Desloratadine is part of a class of drugs called antihistamines. As the name implies, Clarinex-D blocks the effects of histamine. This leads to relief of allergy symptoms -- except for nasal congestion. Pseudoephedrine sulfate (Sudafed®) is a decongestant. It works by decreasing the swelling in the nasal passages, which improves nasal congestion.
