Claritin D is an over-the-counter drug marketed for relief of seasonal allergies causing nasal congestion, according to Drugs.com. Claritin D is a combination of two drugs, an antihistamine and a decongestant. Claritin D should be taken as directed while under the supervision of a medical doctor. Do not take any medication without the consent of physician. Some drugs may interact with the ingredients in Claritin D and should be discussed with the pharmacist or doctor before taking them.
Drugs
According to MediLexicon.com, Claritin D is a combination of loratadine and pseudoephedrine. Loratadine is a non-sedative, 24-hour antihistamine that works by blocking the release of histamine, the chemical that causes allergy symptoms. Pseudoephedrine, is the "D" in Claritin D. It is a decongestant that works by restricting blood to the sinus cavity, reducing nasal inflammation.
About Loratadine
According to National Library of Medicine, loratadine is used to alleviate symptoms of allergies, such as sneezing, irritated eyes and nasal congestion. Loratadine is effective at treating seasonal allergies but will not prevent or treat hives. This drug is not recommended for children younger than 2, unless directed by a doctor. It is non-sedative, so it does not cause drowsiness in healthy adults when taken as directed. Loratadine may be taken on a consistent, daily basis.
About Pseudoephedrine
Pseudoephedrine is a nasal decongestant that restricts the blood vessels in the sinuses to provide normal breathing, according to the National Library of Medicine. Pseudoephedrine is a stimulant that can increase someone's heart rate. It commonly causes excitability, difficulty sleeping and irritability. Someone with heart disease should not take pseudoephedrine. In some states, this drug is only available behind the pharmacist's counter. Avoid excessive amounts of caffeine while taking this drug, as it can enhance the side effects.
Precautions
Drugs.com recommends taking precaution before driving or performing a task that requires alertness, because the drugs may cause blurred vision or impair the ability to think clearly. Do not take diet pills or stimulants without talking with your doctor. Many over-the-counter cold and allergy medications contain the same ingredients and could cause an accidental overdose. Read the labels to prevent an overdose. If symptoms do not improve in three days, talk with your doctor.
Warning
Claritin D, like any drug, may cause an allergic reaction. If taking Claritin D causes a faint pulse, difficulty breathing, swollen lips or tongue, discontinue use and seek medical attention.
