Generic Allegra is a non‑prescription antihistamine containing fexofenadine hydrochloride, used to relieve seasonal allergy symptoms such as sneezing, itchy eyes and runny nose. If you’re hunting for a budget‑friendly option, the UK market offers several routes to secure this medication without compromising safety.
Why Choose Generic Over the Brand?
Both the branded and generic versions share the same active ingredient, dosage strength, and therapeutic effect. The primary difference lies in price. Studies from the UK's Medicines and Healthcare products Regulatory Agency (MHRA) show that generic antihistamines cost on average 60‑70% less than their branded counterparts, delivering the same clinical outcomes.
Understanding the Active Ingredient: Fexofenadine
Fexofenadine is a second‑generation antihistamine that blocks H1 receptors, preventing histamine‑induced inflammation without causing drowsiness. Its pharmacokinetic profile includes a rapid onset (within 1‑2 hours) and a half‑life of about 14hours, making a once‑daily 180mg tablet sufficient for most adults.
The Role of Antihistamines in Seasonal Allergic Rhinitis
Seasonal allergic rhinitis is an inflammation of the nasal mucosa triggered by airborne allergens like pollen, leading to sneezing, nasal congestion and watery eyes. Antihistamines like fexofenadine reduce these symptoms by inhibiting the body’s histamine response.
Finding a Reputable Online Pharmacy
Online pharmacy refers to a licensed digital retailer that dispenses medicines after verifying a prescription (if required) and ships directly to the consumer’s address. In the UK, the General Pharmaceutical Council (GPhC) regulates these outlets. Look for the GPhC registration number on the site’s footer and verify it on the council’s online list.
Legal Landscape: FDA vs. MHRA
While the US Food and Drug Administration (FDA) issues the initial approval for fexofenadine, the UK’s MHRA ensures that any generic version sold locally meets the same quality standards. This dual‑approval system guarantees that the cheap generic Allegra you purchase abroad is no less safe than the version sold in Britain.

Price Comparison: What to Expect
Product | Active ingredient | Typical UK price (per 30‑tablet pack) | OTC status | Onset of relief |
---|---|---|---|---|
Generic Allegra | Fexofenadine 180mg | £5‑£8 | OTC (pharmacy‑only) | 1‑2hours |
Brand Allegra | Fexofenadine 180mg | £12‑£15 | OTC (pharmacy‑only) | 1‑2hours |
Cetirizine (Zyrtec) | Cetirizine 10mg | £4‑£7 | OTC (pharmacy‑only) | 30‑60minutes |
The table illustrates how generic Allegra comfortably fits between the brand version and another popular antihistamine, offering a balance of price and rapid symptom control.
Key Factors to Evaluate Before Purchase
- Regulatory compliance: Confirm the site displays a valid GPhC registration number and mentions MHRA‑approved sourcing.
- Price transparency: Look for a clear breakdown of product cost, shipping, and any taxes. Hidden fees often inflate the final price.
- Packaging integrity: The medication should arrive in sealed foil blisters with a batch number and expiry date clearly printed.
- Customer reviews: Authentic feedback (verified purchase) helps gauge reliability and delivery speed.
- Return policy: Reputable pharmacies allow returns or refunds if the product is damaged or does not match the description.

Potential Pitfalls and How to Avoid Them

- Never purchase from sites that do not display a GPhC number.
- Avoid offers that sound too good to be true-prices below £3 for a 30‑tablet pack usually indicate a problem.
- Check that the site uses HTTPS encryption (look for the lock icon).
- Read the fine print regarding customs duties; some overseas sellers charge hidden import fees.
