Generic Fexofenadine Information

Introduction

Fexofenadine is a second‑generation antihistamine used to relieve the symptoms of allergic conditions. It belongs to the allergy medication group and contains the active compound fexofenadine. In the United Kingdom, the drug is prescribed for seasonal allergic rhinitis (hay fever) and chronic idiopathic urticaria (hives). Its rapid onset, limited sedation, and favourable safety profile make it a first‑line option for adults seeking relief from histamine‑mediated allergic reactions.

What is Fexofenadine?

Fexofenadine is the generic version of Allegra, a well‑known brand name produced by Sanofi. Both contain the same active compound, fexofenadine, which is chemically related to the earlier antihistamine terfenadine but lacks the cardiotoxic metabolites that required cardiac monitoring. Our online pharmacy provides this generic alternative as a cost‑effective treatment option, offering the same therapeutic benefit without the premium price of the branded product.

How Fexofenadine Works

Fexofenadine selectively blocks the histamine H₁ receptor on peripheral mast cells, basophils, and sensory nerves. By preventing histamine from binding, it stops the cascade that leads to vasodilation, increased vascular permeability, and sensory nerve stimulation—processes that cause itching, sneezing, rhinorrhoea, and swelling.

• Onset: Clinical effects typically appear within 1 hour after oral administration.
• Duration: A single dose provides symptom control for up to 24 hours, allowing once‑daily dosing for many patients.
• Clearance: Approximately 30 % of an oral dose is absorbed in the fasted state; food, especially fruit juices, can increase bioavailability by up to 2‑fold. The drug is minimally metabolised and is excreted unchanged in the urine and feces, giving a terminal half‑life of about 14 hours.

Conditions Treated with Fexofenadine

• Seasonal allergic rhinitis – caused by pollen, dust‑mite, or mold exposure. In the UK, an estimated 20 % of adults suffer from seasonal hay fever, creating a substantial demand for rapid, non‑sedating antihistamines.
• Chronic idiopathic urticaria – daily or near‑daily hives that persist for six weeks or longer. Fexofenadine has demonstrated efficacy in reducing wheal size and itch intensity in randomised controlled trials.

Both indications are approved by the Medicines and Healthcare products Regulatory Agency (MHRA) and are supported by European Medicines Agency (EMA) assessment reports.

Who is Fexofenadine For?

• Adults (≥ 12 years) with moderate‑to‑severe symptoms of seasonal allergic rhinitis or chronic idiopathic urticaria who require rapid relief and wish to avoid drowsiness.
• Patients working in safety‑critical environments (e.g., drivers, pilots, machine operators) because the drug has a low risk of impairing cognition or reaction time.
• Individuals with cardiovascular disease – fexofenadine does not prolong the QT interval and is safe for patients taking anti‑arrhythmic drugs, provided drug–drug interactions are respected.

Contra‑indications include known hypersensitivity to fexofenadine or any of the tablet’s excipients, and concurrent use of strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole) that can markedly increase plasma concentrations. Use in pregnancy and lactation should follow the advice of a qualified healthcare professional.

Risks, Side Effects, and Interactions

Common

• Headache
• Dry mouth
• Nausea or mild gastrointestinal discomfort

These events occur in ≤ 10 % of treated adults and are usually self‑limiting.

Rare

• Drowsiness or fatigue (reported in < 2 % of users)
• Palpitation or mild tachycardia

Rare events may resolve without intervention, but patients should report persistent symptoms to a clinician.

Serious

• Anaphylaxis or severe cutaneous reactions (e.g., Stevens–Johnson syndrome) – immediate medical attention required.
• Cardiac arrhythmia when combined with potent CYP3A4 inhibitors or strong P‑glycoprotein blockers (e.g., erythromycin, clarithromycin).

Clinically Relevant Interactions

• Antacids containing aluminium or magnesium – reduce fexofenadine absorption if taken within 15 minutes of the antihistamine.
• Ketoconazole, erythromycin, itraconazole – increase plasma AUC by up to 2‑fold; dose reduction or alternative therapy may be needed.
• Fruit juices (apple, orange, grapefruit) – enhance bioavailability; patients are advised to take the medication with water rather than juice.
• Alcohol – does not potentiate sedation but may exacerbate headache in susceptible individuals.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing: 60 mg tablet taken twice daily (morning and evening) or a single 180 mg tablet once daily. The 30 mg tablet is generally reserved for paediatric use and is not indicated for adults.
• Administration: Swallow whole with a glass of water. Food may be taken with the dose, but avoid fruit juices and antacids within a 15‑minute window.
• Missed dose: If a dose is forgotten, take it as soon as remembered unless it is near the time of the next scheduled dose; do not double‑dose.
• Overdose: Signs may include excessive drowsiness, rapid heart rate, or gastrointestinal upset. Management is supportive; gastric lavage is rarely required. Prompt medical evaluation is advised, especially if cardiac symptoms develop.
• Precautions: Adjust dose in severe renal impairment (e.g., 30 mg once daily) per specialist guidance; no adjustment is required for mild hepatic dysfunction.

FAQ

• Can Fexofenadine be taken with alcohol?
  Fexofenadine does not increase sedation when combined with moderate alcohol consumption, but alcohol may worsen headache in some users. It is advisable to limit intake and observe individual tolerance.

• Is a cold chain required for storage of Fexofenadine tablets?
  No special temperature control is needed. Store the tablets at room temperature (15‑30 °C) in a dry place, away from direct sunlight and moisture.

• What do the tablets look like and how are they identified?
  The 60 mg tablets are typically white, oval‑shaped, and imprinted with “FEX 60”. The 180 mg tablets are larger, round, and may carry the imprint “FEX 180”. In the UK, generic tablets contain the same markings as the branded product but include a distinct batch code for traceability.

• Does Fexofenadine contain any common allergens such as lactose or gluten?
  In the UK formulation, the tablets contain microcrystalline cellulose, lactose monohydrate, and magnesium stearate. Patients with severe lactose intolerance should consult a pharmacist, although the amount per tablet is minimal.

• Can I travel internationally with Fexofenadine and pass customs without issues?
  Yes. Fexofenadine is listed as an over‑the‑counter antihistamine in most jurisdictions. Carry the medication in its original packaging with the prescription label (if applicable) to facilitate customs inspection.

• Are there specific UK import rules for personal use of generic medications?
  The UK allows import of a three‑month supply for personal use without a prescription, provided the product is sourced from a licensed overseas pharmacy. Our online pharmacy ensures compliance with the Medicines and Health products Regulatory Agency (MHRA) guidelines.

• Do drug‑testing laboratories detect fexofenadine?
  Fexofenadine is not a substance of abuse and is not included in standard workplace drug‑testing panels. However, specialized assays can detect it if specifically requested.

• What was the historical development of fexofenadine?
  Fexofenadine was developed in the early 199s as a metabolite of terfenadine, designed to retain antihistamine potency while eliminating the risk of cardiac arrhythmias linked to terfenadine’s hepatic metabolites.

• Which clinical trials established fexofenadine’s efficacy for chronic urticaria?
  A pivotal double‑blind, placebo‑controlled study (JACI 1998) demonstrated a statistically significant reduction in wheal size and itch scores after 14 days of 180 mg daily dosing, leading to its EMA approval for chronic idiopathic urticaria.

• How does fexofenadine compare with cetirizine regarding sedation?
  Both are second‑generation antihistamines, but fexofenadine has a lower propensity for crossing the blood‑brain barrier, resulting in fewer reports of daytime drowsiness compared with cetirizine, especially at higher doses.

• Is there a difference between EU and US formulations of fexofenadine?
  The EU formulation contains a slightly lower amount of magnesium stearate and uses a different film coating to meet European regulatory standards; the active dose and clinical efficacy remain equivalent.

• Can fexofenadine be used safely while breastfeeding?
  Small amounts of fexofenadine appear in breast milk, but studies suggest minimal exposure to the infant. Nevertheless, mothers should discuss any antihistamine use with their health‑care provider.

• Are there any specific warnings for people of Asian descent?
  Pharmacokinetic studies have shown slightly higher plasma concentrations in Japanese subjects, possibly due to genetic variations in drug transporters. Clinicians may consider a lower starting dose in this population.

• What is the recommended shelf‑life of fexofenadine tablets?
  The product remains stable for up to 24 months when stored under recommended conditions. The expiry date is printed on the primary packaging.
