Loratadine-D 24 Hour (generic name loratadine 10 mg / pseudoephedrine sulfate 240 mg extended-release) is an over-the-counter antihistamine-decongestant combination sold under names like Claritin-D 24 Hour, Allergy Relief-D, and various store brands; it's available without a prescription, but if you're comparing what you'll pay, a loratadine-d-24hr coupon can still help since pharmacy prices for this product vary — enter your ZIP above to see today's price at pharmacies near you.
What Is Loratadine-D 24 Hour and How Does It Work?
Loratadine-D 24 Hour combines two active ingredients in one once-daily tablet: loratadine, a non-drowsy antihistamine, and pseudoephedrine sulfate, a decongestant, in an extended-release core. Under the FDA's OTC monograph, it's used for temporary relief of nasal and sinus congestion, sneezing, runny nose, and itchy/watery eyes or itchy nose and throat caused by hay fever (allergic rhinitis) or the common cold.
The tablet is designed to release the decongestant slowly over 24 hours, so it should be swallowed whole. Do not crush, chew, or split it, since breaking the extended-release core can release the full dose at once.
Comparing Prices and Saving on Loratadine-D 24 Hour
Because this is a generic OTC combination, it's sold under several store and brand names, and prices can differ from one pharmacy to the next. There's no manufacturer copay card for this product, but a pharmacy coupon can sometimes bring the price at the register below the shelf price, or below what you'd otherwise pay out of pocket. Enter your ZIP code above to compare current prices at pharmacies near you before you buy.
Keep in mind this product is sold "behind the counter" at pharmacies under the federal Combat Methamphetamine Epidemic Act, so you'll need to show ID and purchases are limited in quantity, even though a prescription isn't required.
Loratadine-D 24 Hour vs. Other Allergy Options
If you don't need the decongestant, plain loratadine covers the antihistamine allergy symptoms on its own. If you need a shorter-acting decongestant combination, loratadine-D 12 Hour is dosed twice daily instead of once. Some people prefer taking the decongestant, pseudoephedrine, separately from the antihistamine so they can adjust each one independently.
Other non-drowsy antihistamines, such as cetirizine and fexofenadine, are also available OTC and are sometimes combined with pseudoephedrine in similar 24-hour products. The brand-name version, Claritin, is the antihistamine-only equivalent without the decongestant.
Safety Information
Loratadine-D 24 Hour does not carry an FDA boxed warning. However, you should not use it with, or within two weeks of, a monoamine oxidase inhibitor (MAOI). Ask a doctor before use if you have heart disease, high blood pressure, thyroid disease, diabetes, glaucoma, or trouble urinating due to an enlarged prostate, since the pseudoephedrine component can raise blood pressure and heart rate and cause insomnia, nervousness, or dizziness. It is not intended for children under 12.
