Loratadine Price‑per‑Mg Calculator
Generic Claritin (loratadine) is a second‑generation antihistamine that relieves sneezing, itchy eyes, and runny nose without causing drowsiness. Buying it cheap online sounds easy, but the market is full of out‑of‑date sites, counterfeit pills, and confusing price tricks. This guide walks you through every step you need to take to snag a safe, affordable pack, from checking pharmacy credentials to comparing price‑per‑milligram values.
What Exactly Is Generic Claritin?
When you see generic claritin on a search page you’re really looking at Loratadine, the chemical name behind the over‑the‑counter brand Claritin. Loratadine belongs to the antihistamine class, which blocks histamine receptors to curb allergy symptoms.
- Strengths: 5mg, 10mg tablets; 5mg/5ml syrup.
- Formulation: Film‑coated tablet, chewable tablet, oral solution.
- Onset: Usually 1‑3hours after ingestion.
- Duration: Up to 24hours per dose.
The drug is approved by the U.S. Food and Drug Administration (FDA) and, for Australian shoppers, by the Therapeutic Goods Administration (TGA). Those approvals guarantee that the active ingredient meets strict potency and purity standards.
How to Spot a Legitimate Online Pharmacy
Not all websites selling "cheap" loratadine are created equal. A legitimate online pharmacy will display clear licensing information, a physical address, and a verifiable pharmacy registration number.
- Check the URL for https:// and a lock icon - that’s basic encryption.
- Look for a pharmacy license number that matches the regulator in your country (e.g., “APN123456” for Australian pharmacies).
- Verify the site on the FDA’s BeSafeOnline list or the TGA’sRegistered Medicines database.
- Avoid sites that require you to pay via wire transfer, cryptocurrency, or gift cards - those are classic red flags.
- Read recent customer reviews that mention product authenticity and packaging quality.
When a pharmacy passes these checks, you can be reasonably confident you’ll receive genuine loratadine tablets that meet the label claim of 5mg per tablet.
Price Comparison: How Cheap Is Too Cheap?
Price alone doesn’t tell the whole story. A cheap offer might hide extra shipping fees, a lower dosage, or even a different compound. Below is a quick side‑by‑side look at the most common options you’ll encounter.
Product | Average price (USD) | Price per mg | Onset of action | Sedation risk |
---|---|---|---|---|
Generic Claritin (loratadine) 10mg, 30tablets | $9.99 | $0.033 | 1‑3hrs | Low |
Brand Claritin 10mg, 30tablets | $19.99 | $0.067 | 1‑3hrs | Low |
Zyrtec (cetirizine) 10mg, 30tablets | $12.49 | $0.042 | 1‑2hrs | Medium |
Benadryl (diphenhydramine) 25mg, 30tablets | $7.99 | $0.011 | 30‑60min | High |
Notice how generic Claritin beats the brand name on a per‑milligram basis while staying non‑sedating. Zyrtec is comparable but a touch more expensive, and Benadryl is cheap but not suitable for daytime use because of its drowsiness.

Dosing, Side Effects, and Interactions
Even a cheap medication can cause trouble if you don’t follow the right dosing regimen. Loratadine’s standard adult dose is one 10mg tablet once daily. For children aged 2‑5 years, the syrup form (5mg/5ml) is recommended at 5ml daily.
The most common side effects are mild headache, dry mouth, and occasional fatigue. Serious reactions - such as rash, swelling, or trouble breathing - are rare but warrant an immediate stop and a call to a health professional.
Because loratadine is metabolized by the liver enzyme CYP3A4, watch out for interactions with:
- Antifungal agents (ketoconazole, itraconazole)
- Macrolide antibiotics (erythromycin)
- Some antidepressants (sertraline)
If you’re on any of those, keep a drug interaction checker handy or ask a pharmacist before placing your order.
Legal and Shipping Considerations
In most countries, loratadine is an over‑the‑counter drug, meaning you don’t need a prescription. However, some jurisdictions treat it as a prescription‑only medication when sold online. Always double‑check the local regulatory rule before clicking “buy”.
Shipping constraints matter too. Customs may hold parcels that don’t include a proper invoice or that appear to contain “unapproved” medicines. To avoid delays:
- Select a pharmacy that ships with a tracking number.
- Make sure the label lists the generic name (loratadine) and dosage.
- For Australian orders, the pharmacy should be TGA‑registered; for U.S. orders, FDA‑registered.
Most reputable sites ship within 3‑5 business days and offer free shipping on orders over a certain amount (often $30‑$40). If you’re buying a bulk pack (e.g., 90 tablets), you’ll usually cross that threshold automatically.
Tips to Get the Best Deal Without Compromising Safety
- Bulk discounts: Buying 90 or 120 tablets can shave $3‑$5 off the per‑tablet price.
- Subscription services: Some online pharmacies let you set a recurring order; you save 10% and never run out.
- Coupon codes: Search for “loratadine coupon” a few days before checkout. Many sites post a fresh code on their home page.
- Compare total cost: Include shipping, handling, and any tax. A $9.99 product with $7.00 express shipping is worse than a $12.99 product with free standard delivery.
- Check expiration dates: Reputable sellers list the manufacturing date on the product page. Avoid lots that are within six months of expiry.
By pairing these tactics with the verification steps above, you’ll consistently land a safe, cheap pack of loratadine.

Frequently Asked Questions
Is generic Claritin as effective as the brand?
Yes. Generic Claritin contains the same active ingredient-loratadine-in the same strength (10mg). FDA and TGA approval guarantee bio‑equivalence, meaning you’ll get the same symptom relief without paying the premium brand price.
Do I need a prescription to buy loratadine online?
In most countries loratadine is over‑the‑counter, so a prescription isn’t required. However, some regions treat it as prescription‑only for online sales. Always verify your local regulation before ordering.
How can I tell if an online pharmacy is legitimate?
Look for a valid pharmacy license, HTTPS encryption, clear contact details, and verification on the FDA or TGA databases. Avoid sites that only accept gift cards or cryptocurrency.
What’s the safest way to store loratadine after delivery?
Store tablets in a cool, dry place away from direct sunlight. Keep them out of reach of children and pets. If you receive syrup, refrigerate after opening and discard after the expiry date on the label.
Can I take loratadine with other allergy meds?
Because loratadine is non‑sedating, it’s often combined with nasal sprays or eye drops. However, avoid stacking multiple oral antihistamines, as that can increase side‑effect risk without adding benefit.
What should I do if I suspect a counterfeit pill?
Stop using the product, keep the packaging, and contact the pharmacy’s customer service. You can also report the issue to the FDA’s MedWatch program or the TGA’s MedSafe portal.
