Generic Allegra is a non‑prescription antihistamine (fexofenadine) that relieves sneezing, watery eyes, and itching caused by seasonal allergies. If you’re hunting for a budget‑friendly way to keep pollen at bay, the internet is full of offers that promise the same relief as the brand name at a fraction of the cost.
Generic drugs are required by the FDA U.S. Food and Drug Administration to contain the same active ingredient, strength, dosage form, and intended use as their brand‑name counterparts. The only real differences lie in price and inactive fillers. For fexofenadine, studies from the American College of Allergy, Asthma, and Immunology show that generic versions achieve 95% bioequivalence with the branded Allegra, meaning you get virtually the same symptom control.

Not every site offering a price that looks too good to be true follows legal standards. Red flags include:
If you encounter any of these, walk away and try a known pharmacy such as Boots, LloydsPharmacy, or a certified international provider.
Fexofenadine comes mainly as:
All forms are bioequivalent, so choose the one that fits your lifestyle. Remember that the oral solution must be stored in a refrigerator after opening, which adds a handling step.
Like any antihistamine, generic Allegra can cause mild reactions. The most frequently reported are:
Serious side effects - such as rapid heartbeat, swelling of the face or throat, or severe rash - are rare (<0.1%). If any of these occur, stop the medication and contact a healthcare professional immediately.
In the UK, fexofenadine is classified as a “pharmacy‑only” medication, meaning you can purchase it without a prescription but only from a registered pharmacy. In the US, it is an over‑the‑counter (OTC) drug, so any reputable online retailer can sell it. Always confirm the pharmacy’s jurisdiction‑specific compliance before completing a purchase.
Once you have your supply, keep a simple log of when you take each tablet. This helps you spot patterns - for example, you might notice that symptoms flare up if you miss a dose. Pair the medication with lifestyle tweaks like using a HEPA filter at home or washing bedding in hot water to reduce allergen load.
Yes. Regulatory agencies require the generic to demonstrate at least 90‑95% bioequivalence, meaning it works just as well for most people.
No prescription is needed, but the seller must be a licensed pharmacy. Look for the NHS or MHRA registration number on the website.
Reputable online pharmacies price generic Allegra between £5 and £8 per 30‑tablet supply. Anything dramatically lower should be flagged as suspicious.
Fexofenadine has few drug interactions, but it can increase levels of certain antibiotics (e.g., erythromycin) and antifungals. Always check with a pharmacist.
Contact the pharmacy’s customer service immediately. Reputable sites will arrange a return and issue a full refund, and they may report the incident to the regulatory body.
Children under 12 should use the pediatric formulation (30mg). The adult 180mg tablet is not recommended for younger kids without a doctor’s guidance.
Unopened tablets remain potent for up to two years if kept in a cool, dry place. Once opened, the oral solution should be used within 30 days and refrigerated.
