Claritin Allergy & Sinus Extra Strength® for Daytime Allergy and Congestion Relief

What Claritin® Allergy & Sinus Extra Strength Is and How It Works

Claritin® Allergy & Sinus Extra Strength combines loratadine, a non-drowsy antihistamine, with extended-release pseudoephedrine, a nasal decongestant. This over-the-counter option helps relieve sneezing, runny nose, itchy eyes, sinus pressure, and stuffy nose. Many shoppers compare the Claritin Allergy & Sinus Extra Strength price across sites to manage out-of-pocket costs, and some look for Claritin Allergy & Sinus Extra Strength without insurance options to save more. Youdrugstore is a licensed Canadian pharmacy headquartered in Manitoba, and our pharmacists review prescriptions before dispensing. We also offer OTC health products online and by phone during posted hours.

We partner with licensed, vetted international pharmacies so you get authentic brand medicines, a wide selection, and fair pricing. Loratadine blocks histamine H1 receptors to reduce allergy symptoms. Pseudoephedrine narrows swollen nasal blood vessels, which opens nasal passages and eases sinus pressure. Extra Strength tablets are typically designed for 24-hour relief in adults and adolescents 12 years and older. Always follow the specific package directions supplied with your product.

Dosage and Usage

• Adults and children 12+: typical dosing for Extra Strength 24-hour tablets is 1 tablet once daily with water. Do not exceed 1 tablet in 24 hours.
• Swallow tablets whole. Do not crush, split, or chew extended-release tablets.
• May be taken with or without food. Avoid taking near bedtime to reduce the chance of insomnia.
• If your product is a 12-hour strength, follow its label: often 1 tablet every 12 hours, not more than 2 in 24 hours.
• Missed dose: if it is close to the next dose, skip the missed dose. Do not double up.
• Avoid other decongestants, stimulant cough-and-cold products, or energy supplements while using pseudoephedrine-containing tablets.
• Do not use within 14 days of monoamine oxidase inhibitor (MAOI) therapy.

• Store at 20–25 °C (68–77 °F). Short excursions 15–30 °C (59–86 °F) are acceptable.
• Keep tablets in the original blister or bottle with the label intact.
• Protect from heat, moisture, and direct sunlight. Do not freeze.
• When traveling, pack tablets in your carry-on with a copy of the product facts. Keep out of reach of children.
• Do not store in a bathroom cabinet or hot vehicle.

Benefits and Savings

This combination offers dual-action relief. Loratadine addresses itching, sneezing, and runny nose, while pseudoephedrine targets congestion and sinus pressure. Extra Strength tablets provide once-daily convenience for continuous daytime coverage. Non-drowsy performance helps you stay productive, and many people find steady control during peak pollen seasons.

Ordering from a Canadian pharmacy often lowers the Claritin Allergy & Sinus Extra Strength cost. Typical savings are 60–80% versus usual US prices, especially on multi-pack sizes. That can be helpful if you pay cash or shop without insurance. Multi-month supplies and bulk promotions can reduce the per-month price further, and we can send gentle reorder reminders by email.

Side Effects and Safety

• Common effects: dry mouth, dry nose, thirst, headache, dizziness.
• Nervousness, restlessness, or insomnia may occur, especially if taken late in the day.
• Increased heart rate or a rise in blood pressure may occur with pseudoephedrine.
• Nausea, decreased appetite, or stomach upset can happen in some people.
• Fatigue or mild drowsiness is uncommon with loratadine but possible.
• Mouth or throat irritation may occur if swallowing with insufficient water.

Serious problems are rare but can include severe hypertension, palpitations, heart rhythm changes, chest pain, confusion, seizures, or severe allergic reactions (rash, swelling, trouble breathing). Do not use with MAOIs or in people with uncontrolled high blood pressure, severe coronary artery disease, narrow-angle glaucoma, urinary retention, or hyperthyroidism. Caution is advised in diabetes, prostate enlargement, kidney or liver disease, pregnancy, and breastfeeding. Not for children under 12 years unless directed by a healthcare professional.

Onset Time

Pseudoephedrine starts to open the nose within about 30–60 minutes, with peak decongestant effect in 2–4 hours. Loratadine’s antihistamine effect begins within 1–3 hours and lasts a full day. Many people notice relief on day one. Congestion and pressure often improve quickly, while itchy and runny symptoms may continue to ease over 2–3 days of steady dosing.

Compare With Alternatives

Zyrtec-D (cetirizine/pseudoephedrine) is another 24-hour or 12-hour combination. Cetirizine can be more sedating for some users, and some prefer loratadine’s non-drowsy profile. Both options provide dual action for allergy symptoms with congestion.

Allegra-D (fexofenadine/pseudoephedrine) offers similar decongestant relief with a different non-drowsy antihistamine. People who do not respond to loratadine may try fexofenadine under label guidance. As with all decongestant combos, stimulant-like effects are possible.

Single-agent antihistamines such as loratadine 10 mg, cetirizine 10 mg, or fexofenadine (various strengths) help itching, sneezing, and runny nose but do not relieve congestion. If congestion is mild or intermittent, a non-decongestant antihistamine plus a saline nasal rinse or an intranasal steroid spray can be a suitable alternative.

Combination Therapy

• Intranasal corticosteroid sprays (e.g., fluticasone or triamcinolone) can be used with loratadine for stronger nasal allergy control.
• Isotonic saline rinses or sprays help clear mucus and moisten nasal passages.
• Lubricating eye drops can ease itchy, watery eyes.
• Analgesics such as acetaminophen or ibuprofen may help sinus headache or facial pressure. Use as directed.
• Avoid other pseudoephedrine- or phenylephrine-containing products to prevent excess decongestant exposure.

Patient Suitability and Cost-Saving Tips

This product suits adults and adolescents 12+ with seasonal or perennial allergies and bothersome nasal congestion or sinus pressure. It is not appropriate for those with uncontrolled hypertension, serious heart disease, narrow-angle glaucoma, urinary retention, or those taking MAOIs. Review all medicines and supplements for potential interactions before starting.

Pregnant or breastfeeding individuals should speak with a healthcare professional. Pseudoephedrine may reduce milk supply in some people. Consider single-agent antihistamines or non-drug measures if congestion is minimal. Always read and follow the package directions.

To lower the Claritin Allergy & Sinus Extra Strength price, consider larger pack sizes or multi-month orders to reduce the per-tablet cost. You can set a simple reorder reminder so you do not run out during allergy season. Savings are available whether you use health coverage or shop without insurance.
