Aerius® Tablets and Syrup for Allergic Rhinitis

Aerius is an antihistamine used for seasonal allergies and hives. This page explains what it treats, how it works, dosing basics, and safety. It also shows access options with US delivery from Canada, plus ways to save on Aerius without insurance.

What Aerius Is and How It Works

Aerius® contains desloratadine, a long-acting antihistamine. It blocks histamine at H1 receptors, which can reduce sneezing, runny nose, itchy eyes, and hives. The medicine is non-sedating for most people, though some may still feel tired. You can review allergy basics in our Allergic Rhinitis category and this practical overview Allergic Rhinitis Hay Fever Symptoms Treatment.

Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.

Some people ask about Aerius generic desloratadine. Desloratadine is the active ingredient; brand and generic options may be available depending on stock. For symptoms that include nasal congestion, your clinician may advise adding a nasal spray if appropriate. You can also review another antihistamine here: Histantil.

Who It’s For

This treatment is used in adults and children for allergic rhinitis. It is also used to relieve itching and hives in chronic spontaneous urticaria. People with severe kidney or liver impairment, or known allergy to desloratadine or loratadine, should avoid it unless a prescriber decides otherwise. Discuss pregnancy or breastfeeding with your healthcare professional before starting. For broader condition support, see Hives.

Dosage and Usage

Follow your prescription label exactly. Many adults take the tablet once daily with or without food. Children may use the oral liquid by age-based guidance from the official label. Swallow tablets whole with water. Do not take more often than directed.

If your clinician prefers tablets, they may reference Desloratadine 5 mg tablets when discussing typical adult regimens. For those who have trouble swallowing, discuss orally disintegrating options or the liquid with your prescriber. Always measure liquids with a marked device.

Strengths and Forms

Availability can vary by pharmacy and manufacturer. Common presentations include:

• Tablets: 5 mg
• Oral solution/syrup: 0.5 mg/mL
• Orally disintegrating tablets: 2.5 mg or 5 mg (varies by market)

Families sometimes ask about flavor and measuring tools for children. Your pharmacist can provide a dosing syringe or cup when filling the liquid. One common listing you may see is Aerius 0.5 mg/mL syrup.

Missed Dose and Timing

If you miss a dose, take it when you remember unless it is close to the next dose. If it is almost time, skip the missed dose and resume your regular schedule. Do not double up. For children, try to give the dose at the same time daily to build a routine. Some caregivers prefer the evening if daytime drowsiness occurs.

For those using the liquid, labeling may list Aerius allergy relief tablets alongside the oral solution. Your prescriber will recommend the form that fits the person’s age and needs.

Storage and Travel Basics

Store at room temperature in a dry place. Keep the bottle tightly closed and protect from excessive heat and moisture. Do not freeze the liquid. Keep all medicine out of reach of children and pets. When traveling, carry this treatment in your hand luggage with the original labeled container. A copy of your prescription can help during security checks. Avoid leaving the medicine in a hot car. Dispose of outdated liquid according to local guidance.

Pen Handling and Sharps Disposal

This product is supplied as tablets or oral liquid. No pens, needles, or sharps are involved. Use a marked measuring device for the liquid to ensure accurate dosing.

Benefits

Antihistamines in this class can relieve sneezing, runny or itchy nose, and itchy, watery eyes. They may also decrease the number and size of hives and reduce itching. Once-daily schedules are convenient for many people. The non-drowsy profile is helpful for daytime activities, though individual responses vary. This medicine can be taken with or without food.

Side Effects and Safety

• Headache
• Dry mouth
• Fatigue or drowsiness
• Sore throat
• Upset stomach

Serious reactions are uncommon but can include allergy to the drug, severe rash, swelling of the face or throat, fast heartbeat, or severe dizziness. Seek urgent care for breathing trouble or swelling. Use caution with alcohol or other sedating medicines, which may increase drowsiness. People with significant kidney or liver disease should consult a prescriber before use.

Drug Interactions and Cautions

Tell your healthcare professional about all medicines, vitamins, and herbal products. Taking multiple antihistamines together can increase side effects. Alcohol and sedatives may add to drowsiness. Strong inhibitors of certain liver enzymes can affect antihistamines; your prescriber will evaluate risks. If you are pregnant, planning pregnancy, or breastfeeding, discuss whether benefits outweigh potential risks. Stop and seek care if you notice an allergic reaction to the product.

What to Expect Over Time

Many people notice symptom relief on days they take the medicine. Steady, daily use during allergy season may help maintain control. If symptoms persist, your clinician may consider adjusting therapy by adding a compatible nasal spray or reviewing triggers. Track your symptoms, such as sneezing or itching, to share at follow-up. Consistent timing each day can support better routine use.

Compare With Alternatives

Some patients do well with a different nonsedating antihistamine such as Claritin. Others with prominent nasal symptoms may add or switch to a steroid nasal spray like Omnaris Nasal Spray. Your prescriber will match therapy to your symptoms, medical history, and age.

Availability and Substitutions

Supply may vary by strength and form. If a specific pack is unavailable, a prescriber may consider a comparable desloratadine product or another antihistamine. Your pharmacist can help coordinate with your clinician if a substitution is needed. We do not list restock dates.

Patient Suitability and Cost-Saving Tips

This therapy suits many adults and children who need once-daily allergy control. It may not fit people with severe renal or hepatic disease unless adjusted by a prescriber. If you are very sensitive to drowsiness, start when you can monitor how you feel. Consider multi-month fills to reduce per-fill costs. Set reminders on your phone so you do not miss doses or refills. When traveling, keep your medicine in original packaging to avoid delays at security.
