Looking for a fexofenadine HCl coupon? Fexofenadine hydrochloride is the non-drowsy, second-generation antihistamine sold over the counter as Allegra and its generics. It relieves seasonal allergy symptoms such as runny nose, sneezing, and itchy, watery eyes, and it also treats hives. Even though it is available without a prescription, some pharmacies price it lower when you use an Rx.com coupon or when your provider writes it as a prescription. Enter your ZIP above to see today's price at pharmacies near you.
What is fexofenadine HCl and how does it work?
Fexofenadine hydrochloride is a second-generation (non-sedating) H1 antihistamine. It blocks histamine, the natural chemical your body releases during an allergic reaction, which is what causes sneezing, a runny nose, and itchy, watery eyes. It is best known by the brand names Allegra, Allegra Allergy, Children's Allegra, and Allegra ODT (orally disintegrating tablets).
Doctors and pharmacists use fexofenadine for two main purposes: relief of seasonal allergic rhinitis (hay fever) symptoms in adults and children 2 years and older, and treatment of ongoing skin itching and hives (chronic idiopathic urticaria) in patients as young as 6 months. It was originally an FDA-approved prescription medicine and is now widely sold over the counter.
How to save on fexofenadine HCl with an Rx.com coupon
Fexofenadine is available over the counter, but that does not always mean it is cheapest off the shelf. Prices vary widely by pharmacy and package size, and in some cases the cost is lower with an Rx.com coupon or when your provider writes it as a prescription. Because a generic is available, you can often find the same fexofenadine hydrochloride for less than the brand-name Allegra.
To find your price, enter your ZIP above to see today's cost at pharmacies near you, then show the Rx.com coupon at the counter. The maker of Allegra also lists its own offers on its official website (allegra.com); those terms vary and are separate from the Rx.com coupon. Compare both to see which is lower for the package size you need.
Fexofenadine vs. other allergy medicines
Fexofenadine is one of several non-drowsy, second-generation antihistamines. The main alternatives work in a similar way but differ slightly in how likely they are to cause drowsiness and how they are dosed:
- cetirizine (Zyrtec) — effective but slightly more likely to cause drowsiness in some people.
- loratadine (Claritin) — another once-daily, non-sedating option.
- levocetirizine (Xyzal) — a close relative of cetirizine.
- desloratadine (Clarinex) — a close relative of loratadine.
- allegra-d — fexofenadine combined with a decongestant (pseudoephedrine) for added nasal congestion relief.
Which one is best is a personal choice; some people respond better to one antihistamine than another. Compare prices for each above and talk with your pharmacist or provider if you are unsure. This is general information, not medical advice.
Safety and how to take fexofenadine HCl
Fexofenadine has no boxed warning and is generally very well tolerated and non-sedating at recommended doses. The most common side effects are headache, dizziness, and diarrhea, along with nausea or vomiting in children. Rare hypersensitivity reactions such as rash, swelling, or trouble breathing are a medical emergency and need immediate care.
A few practical tips: do not take fexofenadine with fruit juices (apple, orange, or grapefruit), because they reduce how much of the drug your body absorbs and can make it work less well; take it with plain water instead. Antacids that contain aluminum or magnesium can also lower absorption, so separate the two doses by a couple of hours. If you have kidney problems, your dose may need to be adjusted. This is general information and not a substitute for medical advice; follow the label and ask your provider or pharmacist about your specific situation.
