Claritin® Allergy & Sinus Extra Strength for allergy and sinus relief

What Claritin Is and How It Works

Claritin® Allergy & Sinus Extra Strength combines an antihistamine with a decongestant to relieve seasonal and year-round allergy symptoms. It helps with sneezing, runny nose, itchy eyes, sinus pressure, and nasal congestion. Many shoppers look for claritin allergy extra strength without insurance, and this over-the-counter option offers straightforward access at Canadian prices.

Claritin® products contain loratadine, a non-drowsy antihistamine. Extra Strength allergy and sinus formats often pair loratadine with pseudoephedrine, a long-acting decongestant. Together, they block histamine effects and shrink swollen nasal passages. Tablets are taken by mouth and are designed for either 12-hour or 24-hour relief, depending on the package.

Dosage and Usage

Always follow the exact directions on your specific package and ask a healthcare professional if unsure. Strengths and dosing frequency vary by format.

• Adults and children 12+: For many Extra Strength 12-hour tablets (loratadine with pseudoephedrine 120 mg), take 1 tablet every 12 hours. Do not exceed 2 tablets in 24 hours.
• For 24-hour formats, take 1 tablet once daily. Do not exceed 1 tablet in 24 hours.
• Swallow tablets whole with water. Do not crush or chew extended-release tablets.
• If a dose is missed and it is close to the next dose, skip the missed dose. Do not double up.

• Storage: Store your tablets at room temperature, away from moisture and heat. Keep in the original packaging and out of children’s reach.
• Travel: Pack your medicine in your carry-on. Keep your original labeled packaging for security checks. Carry only your personal-use quantity.
• Ordering: You can order claritin sinus and allergy extra strength online and choose the quantity that suits your needs.

Benefits and Savings

The antihistamine component eases sneezing, itching, and runny nose, while the decongestant relieves stuffy nose and sinus pressure. Many users appreciate non-drowsy daytime control from loratadine and dependable decongestant relief from pseudoephedrine. Claritin® Allergy & Sinus Extra Strength is convenient for outdoor activities, work, and travel.

Ordering from YouDrugstore helps you access Canadian pricing. Typical savings range from 60–80% versus common US retail prices, especially for multi-pack orders. If you pay without insurance, our transparent pricing and selection make it easier to manage seasonal needs. Reorder reminders help you stay stocked during peak allergy months.

Side Effects and Safety

• Common: dry mouth, headache, nausea, nervousness, dizziness, trouble sleeping, or mild upset stomach.
• Less common: rapid heartbeat, palpitations, tremor, sweating, or increased blood pressure.
• Serious: severe allergic reaction, chest pain, shortness of breath, fainting, severe hypertension, urinary retention, or vision changes. Seek urgent care if serious effects occur.

Do not use with monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping an MAOI. The decongestant may worsen high blood pressure, heart disease, hyperthyroidism, glaucoma, or urinary retention due to enlarged prostate. Ask a healthcare professional before use if you have these conditions. Use caution with stimulants, caffeine, and other cold or allergy medicines that contain decongestants. Claritin® products are not for children under 12 unless labeled otherwise. If pregnant or breastfeeding, seek medical advice before use.

Onset Time

Pseudoephedrine starts easing nasal congestion within about 30–60 minutes, with effects that generally last 12–24 hours depending on the tablet strength. Loratadine often begins to help allergy symptoms within 1–3 hours, with peak benefit by about 8–12 hours for many people. Consistent daily use during high-allergen periods can improve control.

Compare With Alternatives

Claritin® Allergy & Sinus Extra Strength is similar to other antihistamine-decongestant combinations. Claritin-D products also pair loratadine with pseudoephedrine, with 12-hour or 24-hour options. If you want stronger antihistamine effects, cetirizine plus pseudoephedrine (often called Zyrtec-D) may offer more potency for some users, but it can be more sedating. Fexofenadine plus pseudoephedrine (often called Allegra-D) is another non-drowsy option with twice-daily or once-daily dosing depending on the format.

Some people prefer plain antihistamines without a decongestant when congestion is mild. Others use an intranasal corticosteroid spray for persistent nasal symptoms and reserve decongestants for short periods. Choice depends on symptom pattern, sensitivity to stimulants, and medical history.

Combination Therapy

Combination strategies can target different pathways. Many adults pair a non-drowsy antihistamine with an intranasal steroid spray for steady control of nasal inflammation. Saline rinses can help thin mucus and clear allergens. Avoid taking multiple oral or topical decongestants at the same time to reduce the risk of elevated blood pressure, insomnia, or palpitations. If you use other medicines that affect heart rate or blood pressure, speak with a healthcare professional before adding a decongestant.

Patient Suitability and Cost-Saving Tips

This product suits adults and adolescents 12+ who need relief from both allergy symptoms and nasal congestion. It may not be suitable for those with uncontrolled hypertension, significant heart disease, glaucoma, severe kidney disease, hyperthyroidism, or urinary retention. People who are very sensitive to stimulants or who have insomnia may prefer a non-decongestant antihistamine. Always read the label and consult a healthcare professional if you have complex conditions or take multiple medicines.
