Claritin Allergy & Sinus® (loratadine + pseudoephedrine) Tablets

What Claritin Allergy & Sinus® Is and How It Works

Claritin Allergy & Sinus® combines loratadine and pseudoephedrine in one tablet. It relieves sneezing, runny nose, itchy eyes, and nasal congestion from seasonal or indoor allergies. Many shoppers search for claritin allergy & sinus, claritin allergy sinus, and claritin sinus for these symptoms. The 12-hour option contains loratadine 5 mg with pseudoephedrine 120 mg taken twice daily. The 24-hour option contains loratadine 10 mg with pseudoephedrine 240 mg taken once daily.

Loratadine is a second-generation antihistamine that blocks H1 receptors. It helps reduce allergy symptoms without strong drowsiness in most people. Pseudoephedrine is a decongestant. It shrinks swollen nasal blood vessels to ease stuffiness and sinus pressure. The extended-release core helps maintain relief over 12 or 24 hours. Labels may read claritin 12 hour allergy and sinus or claritin 24 hour allergy and sinus. You may also see claritin allergy and sinus 12 hour, claritin allergy and sinus 24 hour, claritin allergy plus sinus, or claritin plus sinus on packages.

Dosage and Usage

Follow the product label or guidance from a healthcare professional. Swallow tablets whole with water. Do not crush, split, or chew extended-release tablets.

• Adults and children 12+: 12-hour tablets: 1 tablet every 12 hours, as needed.
• Adults and children 12+: 24-hour tablets: 1 tablet once daily, as needed.
• Take the lowest effective dose for the shortest time needed.
• Avoid taking near bedtime because pseudoephedrine may cause insomnia.
• Do not use with other products that contain antihistamines or decongestants unless advised.

Missed dose

• If a dose is missed, take it when remembered unless it is near the next dose.
• Skip the missed dose if it is almost time for the next dose.
• Do not double doses.

Storage and travel

• Store in the original package at room temperature away from moisture.
• Keep out of reach of children and pets.
• When traveling, carry tablets in your hand luggage with the label intact.
• Avoid excessive heat or freezing.

Benefits and Savings

This combination targets two problems at once. Loratadine eases itching, sneezing, and runny nose. Pseudoephedrine opens nasal passages and reduces sinus pressure. Relief lasts 12 or 24 hours depending on the tablet selected. Many people prefer once-daily dosing for busy days. Others choose the 12-hour format to avoid evening stimulation.

Side Effects and Safety

Most people tolerate loratadine well. Pseudoephedrine can cause stimulation. Read the label warnings and speak with a healthcare professional if unsure.

• Common: dry mouth, headache, nervousness, dizziness, trouble sleeping, nausea.
• Less common: rapid heart rate, palpitations, increased blood pressure, tremor.
• Serious (seek medical help): chest pain, severe dizziness or fainting, severe rash, swelling of face or throat, trouble breathing, severe anxiety.

Do not use with monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping an MAOI. People with high blood pressure, heart disease, hyperthyroidism, glaucoma, diabetes, or trouble urinating due to prostate enlargement should ask a healthcare professional before use. Use caution in older adults. In pregnancy or breastfeeding, discuss risks and benefits with a healthcare professional before use.

Onset Time

Pseudoephedrine congestion relief often starts within 30 to 60 minutes. Many feel improved airflow within the first hour. Loratadine allergy relief typically begins within 1 to 3 hours and builds through the day. The 12-hour tablet maintains relief for about half a day. The 24-hour tablet supports all-day symptom control for many users.

Compare With Alternatives

Single-ingredient loratadine (Claritin®) may be enough if nasal congestion is mild or absent. It helps itching, sneezing, and runny nose without the stimulant effects of pseudoephedrine. If stuffiness is the main issue, a short course of a topical nasal decongestant spray may help, but avoid use beyond a few days to prevent rebound congestion.

Other combination options include cetirizine + pseudoephedrine (Zyrtec-D®) and fexofenadine + pseudoephedrine (Allegra-D®). Cetirizine can cause more drowsiness in some users compared with loratadine. Fexofenadine is typically non-drowsy but must be separated from certain juices. All “-D” combinations contain pseudoephedrine and share similar stimulant and blood pressure warnings.

Intranasal corticosteroid sprays like fluticasone or mometasone treat nasal inflammation directly and can be paired with an oral antihistamine if needed. Saline rinses can also ease dryness and help clear allergens.

Combination Therapy

Many people use Claritin Allergy & Sinus® alongside non-drug measures. Rinse with isotonic saline to clear pollen and dust. Use a humidifier if indoor air is dry. An intranasal steroid may be added for persistent nasal inflammation. Avoid taking other oral decongestants or caffeine late in the day to reduce insomnia risk. Do not combine with other antihistamines unless a healthcare professional agrees.

Patient Suitability and Cost-Saving Tips

This product is intended for adults and children 12 years and older. It is not for younger children. Those with cardiovascular conditions or uncontrolled hypertension should seek medical advice before using any pseudoephedrine-containing product. People sensitive to stimulants may prefer the 12-hour option and take it earlier in the day. Those needing steady, daylong control may choose the 24-hour format.

Save by comparing claritin 12 hour allergy and sinus with claritin allergy and sinus 24 hour to match dosing needs. Buying multi-month supplies when available can lower the per-month cost. You can set simple reorder reminders in your account to avoid gaps during allergy season. Our team can help you compare claritin allergy & sinus options during office hours by chat.
