Frequently asked questions about desloratadine

Desloratadine is a prescription medication used for the treatment of allergy symptoms. It is commonly supplied as an oral tablet meant to be swallowed or an orally disintegrating tablet. While desloratadine cannot cure allergies, it helps fight your body’s natural response to allergenic irritants, which helps minimize symptoms of itching, sneezing, and redness.

Desloratadine is prescribed to treat symptoms caused by an allergic reaction. Allergic reactions happen when your body thinks that harmless substances, like pet dander or peanuts, are actually pathogens that could make you sick. When this happens, your body prompts an immune response - which causes the symptoms like itchy eyes, itchy or runny nose, and scratchy throat that make allergic reactions troublesome.

Seasonal allergy symptoms can include allergic rhinitis (sneezing, runny nose, itchy nose, sinus pressure or pain, nasal congestion), and swollen or red itchy eyes. There is no cure for allergies, but a treatment plan can manage the symptoms listed above.

Desloratadine is also prescribed for the treatment of hives. Hives, also known as urticaria, are red, itchy bumps on the skin caused by exposure to an irritant or allergen. The size and severity of these welts will vary, but they often migrate to various areas of the body. All sorts of things can trigger hives. Exposure to an irritating substance (known as an allergen) will trigger your immune system’s allergic response, a release of chemicals called histamines. This reaction may result in hives and swelling. Pollen, pet dander, mold spores, and food allergies can all cause hives.

Desloratadine belongs to a class of drugs known as antihistamines. These medications work by blocking the body's natural reaction to histamines. Histamines are chemicals released by your body in response to irritants. An allergic reaction occurs when your body mistakenly believes a substance is harmful, leading to sneezing, itching, swelling, and other symptoms. By blocking the effect of histamines, medications like desloratadine reduce the symptoms listed above.

Desloratadine has been shown to cause mild side effects. Talk to a health care provider if these adverse reactions become severe or do not go away after a few days.

Common symptoms reported from desloratadine use include:

  • Headache
  • Dizziness
  • Diarrhea
  • Fatigue
  • Dry mouth
  • Muscle pain

This is not a complete list of adverse effects – though these are the most common. Seek medical attention right away if you experience symptoms such as swelling, difficulty breathing, rash, hives, or weight gain while taking desloratadine.

As with all prescription medication, be sure to inform the prescribing doctor about any medical conditions you have been previously diagnosed with, as well as any medication/ supplements you are currently taking before starting treatment with desloratadine. Desloratadine can interact with other forms of medication and substances, causing potentially serious side effects. In addition, let your doctor know if you are pregnant or plan on becoming pregnant. If you become pregnant while taking desloratadine, inform your health care provider immediately.

Desloratadine is commonly supplied as an oral tablet to be swallowed or an orally disintegrating oral tablet. The exact dosage you will be prescribed will depend on your age, medical history, and the condition being treated.

Most adults and children over the age of 12 are prescribed one tablet (to be swallowed or left to disintegrate in the mouth) per day.

For those who have been prescribed a liquid solution, this often means 2 teaspoons of the medication to be taken once a day. Children younger than 11 are often prescribed 1 teaspoon of liquid solution per day.

Do not crush or chew oral desloratadine tablets. Take the medication exactly as prescribed by your health care provider. Do not discontinue or increase your dosage of desloratadine without consulting your provider first. If you begin to experience adverse side effects while taking this medication, like those listed above, inform your provider right away.

Desloratadine is currently only available via prescription. This means that the use of this drug must be authorized by a licensed health care provider.
