Generic Claritin Cost Calculator
Generic Claritin is a loratadine‑based antihistamine that relieves sneezing, runny nose and itchy eyes caused by seasonal allergies. It contains the same active ingredient as the brand name Claritin but is sold at a lower cost because it doesn’t carry the trademark premium.
Quick Summary
- Generic Claritin = loratadine, an OTC antihistamine.
- UK‑regulated online pharmacies must display a valid MHRA license.
- Compare per‑tablet prices; 10mg tablets often cost £0.08‑£0.12.
- Check dosage, expiration date and shipping policies before ordering.
What Makes Generic Claritin Different?
Both brand Claritin and its generic counterpart use loratadine as the active molecule. The generic version drops the brand’s marketing spend, which brings the price down dramatically. In the UK, the Medicines and Healthcare products Regulatory Agency (MHRA) ensures that any product labelled “generic loratadine” meets the same purity, strength and safety standards as the branded product.
How Loratadine Works
Loratadine blocks histamine receptors (H1) in the body. When pollen or pet dander triggers the immune system, histamine is released, leading to classic allergy symptoms. By preventing histamine from binding, loratadine reduces those symptoms without making you drowsy in most people.
Finding a Safe Online Pharmacy
Not every website that promises “cheap Claritin” is trustworthy. Follow this checklist before you click ‘Buy’:
- Verify the MHRA licence number on the pharmacy’s footer.
- Look for a clear privacy policy and secure HTTPS connection.
- Check whether the site displays a physical UK address and a customer service phone number.
- Read recent customer reviews on independent forums (e.g., Reddit’s r/ukmedicine).
- Confirm that the pharmacy lists the exact dosage form (10mg tablet) and packaging size you need.
Sites that pass these tests are typically listed on the MHRA’s “Registered Online Pharmacy” register. Examples include Pharmacy2U, LloydsPharmacy.com and TheGenericDrugStore (fictional for illustration).

Price Comparison - What to Expect
Product | Active Ingredient | Typical Price (10mg tablet) | Onset of Relief | Average Sedation |
---|---|---|---|---|
Generic Claritin | Loratadine | £0.08‑£0.12 | 1‑2 hours | Low |
Brand Claritin | Loratadine | £0.32‑£0.40 | 1‑2 hours | Low |
Reactine (Cetirizine) | Cetirizine | £0.14‑£0.18 | 30‑60 minutes | Medium |
Allegra (Fexofenadine) | Fexofenadine | £0.20‑£0.25 | 1‑2 hours | Low |
When you multiply the per‑tablet cost by a typical 28‑day supply, the savings add up to over £8 compared to the brand. Shipping for most UK pharmacies is free for orders over £20, so bulk buying often stays under £5 total cost.
Ordering Steps - From Cart to Doorstep
- Visit a vetted site and navigate to the "Allergy" or "Antihistamine" category.
- Select Generic Claritin 10mg tablets and choose the pack size (e.g., 28, 56, or 84 tablets).
- Add to basket and review the order summary. Verify the MHRA licence number displayed next to the product.
- Enter your delivery address (UK mainland addresses receive standard 2‑3day service).
- Choose a payment method - most sites accept debit/credit cards and PayPal.
- Confirm the order. You’ll receive an email with a tracking link; keep it in case you need to contact support.
Most reputable pharmacies also include a printed Patient Information Leaflet (PIL) inside the package, which matches the official NHS guidance.
Safety, Dosage and Side‑Effect Checklist
Loratadine is approved for adults and children over 12years at a dose of 10mg once daily. For younger children, a pediatric formulation (5mg) exists, but it’s sold under separate brand names.
- Common side effects: mild headache, dry mouth, occasional nausea.
- Rare reactions: rash, swelling of the face, difficulty breathing - seek medical help immediately.
- Drug interactions: avoid simultaneous use with strong CYP3A4 inhibitors (e.g., ketoconazole) as they can raise loratadine levels.
- Pregnancy & breastfeeding: considered safe, but always confirm with a GP.
If you’re already taking other medications-antibiotics, antidepressants, or heart drugs-double‑check with a pharmacist or your doctor before adding a new antihistamine.

Understanding your allergy better can help you stay ahead of the season. Consider reading about:

- Environmental controls: HEPA filters, dust‑mite covers, and pollen forecasts.
- Alternative non‑sedating antihistamines and their comparative effectiveness.
- How the NHS “Allergy Services” pathway works for chronic sufferers.
These topics sit in the broader “Health & Wellness” cluster, while the specifics of loratadine dosage belong to the narrower “Allergy Medication” sub‑cluster.
Frequently Asked Questions
Is generic Claritin legal to buy from overseas websites?
Only if the vendor holds a valid MHRA licence to sell medicines in the UK. Unlicensed imports can be seized at the border and may not meet safety standards.
How long does a standard 28‑tablet pack of generic Claritin last?
At the recommended 10mg once‑daily dose, one pack provides a full month of relief.
Can I take generic Claritin with my blood pressure medication?
Loratadine has a low potential for interaction with most antihypertensives, but it’s wise to confirm with your GP or pharmacist.
What should I do if I receive damaged tablets?
Contact the pharmacy’s customer service immediately. Reputable sellers will replace the batch at no extra cost and report the incident to the MHRA.
Is there a cheaper way than buying a full pack?
Some online pharmacies offer “split‑pack” options (e.g., 14 tablets) at a slightly higher per‑tablet price, but the total spend is lower if you only need short‑term relief.
Does generic Claritin work as fast as the brand?
Yes. Because the active ingredient and formulation are identical, the onset and effectiveness match the branded version.
