Claritin Allergy & Sinus® Tablets for Allergy and Sinus Congestion

This non-drowsy combination pairs an antihistamine with a decongestant. Claritin Allergy & Sinus® is used to relieve allergies with sinus pressure and stuffiness, with US delivery from Canada for convenient access. This page explains what it treats, how to use it, and key safety details.

What Claritin Is and How It Works

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This medicine contains loratadine, a selective H1 antihistamine, and pseudoephedrine, a nasal decongestant. It helps reduce sneezing, runny nose, itchy eyes, and congestion linked to allergic rhinitis. Loratadine blocks histamine effects in the nose and eyes. Pseudoephedrine constricts swollen nasal blood vessels to open the passages.

The treatment is designed to be non-sedating for most people. However, the decongestant may cause alertness or jitteriness in some users. The combination comes in 12-hour and 24-hour options to match daytime or all-day needs. Use the product label and your clinician’s guidance to choose the right schedule.

If your symptoms are mainly congestion and pressure, a decongestant-containing option may be appropriate. If dryness or stimulant effects become bothersome, speak with a healthcare professional about alternatives.

Who It’s For

This product is intended for adults and adolescents who have seasonal or perennial allergic rhinitis with nasal congestion and sinus pressure. It can also help those whose allergies trigger postnasal drip and sinus discomfort. People who only need itch or sneeze relief may do well with an antihistamine alone.

Avoid this medicine if you have severe or uncontrolled high blood pressure, significant heart disease, narrow-angle glaucoma, severe urinary retention, or if you are taking an MAOI or have taken one in the past 14 days. Ask a healthcare professional before use if you have diabetes, thyroid disease, prostate enlargement, or liver or kidney concerns. Learn more about the condition in Allergic Rhinitis and Nasal Congestion resources, or browse Allergies.

Dosage and Usage

Follow the product label and your prescriber’s directions. Swallow tablets whole with water. Do not crush or chew. Take with or without food, and avoid taking close to bedtime if the decongestant affects your sleep.

Daytime users may prefer a 12-hour option taken twice daily. Those needing once-daily convenience may prefer an all-day tablet. Claritin Allergy & Sinus 12 Hour is generally taken in the morning and early evening. Space doses evenly, and do not exceed the labeled maximum.

Drink fluids regularly unless told otherwise, as hydration can help thin mucus. If you also use a saline spray or steroid nasal spray, use those as directed and at different times if advised by your clinician.

Strengths and Forms

This product is supplied as extended-release oral tablets in 12-hour and 24-hour formats. Availability may vary by pack size and manufacturer.

Commonly listed presentations include loratadine 5 mg with pseudoephedrine 120 mg ER for half-day relief, and loratadine 10 mg with pseudoephedrine 240 mg ER for once-daily use. For specificity, many labels list loratadine 10 mg pseudoephedrine 240 mg ER tablets. Check the exact strength on your pack.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to your next scheduled time. If it is late in the day, it may be better to skip the missed dose to reduce the chance of insomnia. Do not double up to make up a missed dose.

If symptoms are mainly daytime, start your schedule in the morning and reassess as needed. For all-day control, consider whether a once-daily option aligns with your routine. Ask a clinician if you are unsure about timing for loratadine pseudoephedrine tablets.

Storage and Travel Basics

Store tablets at room temperature in a dry place away from moisture and direct light. Keep them in the original blister or bottle with the label intact. Close the cap tightly and keep out of reach of children and pets.

When traveling, carry your medicine in your hand luggage with the original package for identification. Pack only what you need, plus a small buffer per your itinerary. If you use a travel pill case, keep the labeled carton or a copy of your receipt as proof of content. For longer trips, set reminders on your phone to maintain consistent dosing times.

Benefits

This combination provides broad symptom coverage for people who need relief from both allergies and congestion. The antihistamine supports relief from sneezing, runny nose, and itchy eyes. The decongestant can reduce sinus pressure and help you breathe more comfortably through your nose.

Once- or twice-daily schedules offer flexibility for busy routines. Many prefer a morning dose to avoid sleep disruption. Non-drowsy Claritin Allergy & Sinus is an option when you want less daytime sedation than some older antihistamines.

Side Effects and Safety

• Headache
• Dry mouth or throat
• Nervousness or jitteriness
• Insomnia or trouble sleeping
• Nausea or upset stomach
• Dizziness
• Increased heart rate or palpitations

Serious effects are uncommon but can include severe hypertension, chest pain, shortness of breath, or urinary retention. Stop the medicine and seek urgent care if you experience severe reactions, fainting, or signs of an allergic reaction such as swelling of the face, lips, or tongue. Older adults and those with cardiovascular disease may be more sensitive to decongestants. The combination in loratadine pseudoephedrine tablets can also aggravate anxiety or insomnia in some people.

Drug Interactions and Cautions

Do not use with monoamine oxidase inhibitors (MAOIs) or within 14 days of stopping one. Avoid taking with other decongestants or stimulants, including certain migraine medicines or weight-loss products. Use caution with some antidepressants and blood pressure therapies; ask a healthcare professional to review your regimen.

Limit caffeine if you notice jitteriness. Alcohol can increase dryness or dizziness. If you have glaucoma, an enlarged prostate, thyroid disease, diabetes, or heart rhythm problems, seek medical advice before using this product. Always read the label and consult an official source if unsure.

What to Expect Over Time

Many people notice relief of sneezing and runny nose after the first doses, with congestion easing as the decongestant effect builds. Consistent timing day to day may improve symptom control. If your allergy triggers are persistent, consider pairing this treatment with allergen avoidance strategies like keeping windows closed during peak pollen seasons.

Compare With Alternatives

Some people do well with an antihistamine alone when congestion is mild. Diphenhydramine offers short-term relief but may cause drowsiness; see Benadryl. Others benefit from a nasal corticosteroid to reduce inflammation in the passages; review Omnaris® Nasal Spray. Your clinician can help choose based on your symptoms and health history.

Availability and Substitutions

Stock can vary by strength and pack size.

We do not provide restock dates; please check back or speak with your healthcare professional about alternatives that fit your needs.

Patient Suitability and Cost-Saving Tips

You may be a good candidate if your allergies include nasal stuffiness along with sneezing and itch. You may not be a good candidate if you have uncontrolled hypertension, serious heart disease, glaucoma, urinary retention, or if you take an MAOI. Discuss with a clinician if you are pregnant or nursing.

To save, consider multi-month supplies when appropriate for your season and symptom pattern. Set refill reminders so you don’t run out during high-pollen periods. Compare once-daily versus twice-daily formats and choose the one you will take consistently. Read more background in Drug Allergies and general respiratory guidance in What Is Asthma.
