Aerius® (desloratadine) 5 mg Tablets for Allergies and Hives

What Aerius® Is and How It Works

Aerius® is desloratadine, a non-drowsy second-generation antihistamine used to relieve allergic symptoms such as sneezing, runny nose, itchy or watery eyes, and hives. It is available as 5 mg tablets and as oral liquid at 0.5 mg/mL. Many people choose Aerius 5 mg for once-daily relief that lasts 24 hours.

Desloratadine blocks H1 histamine receptors. This reduces the effect of histamine released during allergic responses. It helps with Seasonal Allergic Rhinitis, Perennial Allergic Rhinitis, and Chronic Idiopathic Urticaria. The relief starts quickly and continues all day with once-daily dosing.

• Children 2–5 years: 1.25 mg once daily (2.5 mL of 0.5 mg/mL oral liquid).
• Swallow tablets whole with water. Take the oral liquid with a marked dosing device.
• With or without food. Aim for the same time each day.

Missed dose guidance:

• If a dose is missed, take it when remembered the same day.
• If it is near the time of the next dose, skip the missed dose.
• Do not double a dose to make up for a missed one.

Storage and travel tips:

• Store at room temperature, about 15–30°C (59–86°F).
• Keep tablets in the original blister or bottle to protect from moisture.
• Keep the oral liquid tightly closed and avoid freezing.
• When traveling, pack in your carry-on with a copy of your order details.

Side Effects and Safety

Most people tolerate desloratadine well. Some experience mild effects. Seek urgent care for signs of a severe reaction.

• Common: dry mouth, fatigue, headache, sore throat, dizziness, nausea.
• Less common: sleepiness, stomach discomfort, muscle pain, constipation.
• Serious (seek medical help): fast or irregular heartbeat, severe rash, swelling of face or throat, trouble breathing.

Use caution in severe kidney impairment. Discuss use in pregnancy or when breastfeeding. Check for interactions if taking other sedating medicines, alcohol, or strong CYP3A4 inhibitors. Do not combine with other desloratadine-containing products.

Onset Time

Many people begin to feel relief within 1 hour of dosing. Maximum effect can build over several hours, and a single dose provides relief for about 24 hours. Daily use during your allergy season can help maintain steady symptom control.

Compare With Alternatives

Desloratadine is in the same family as loratadine, cetirizine, and fexofenadine. All are second-generation antihistamines. They differ slightly in speed, drowsiness risk, and individual response.

Loratadine is non-drowsy for most and taken once daily. Cetirizine may act quickly but has a higher chance of sleepiness in some users. Fexofenadine is also non-drowsy and taken once or twice daily depending on the strength. For patients with concomitant allergic rhinitis and asthma, a leukotriene receptor antagonist such as Singulair® or its generic Montelukast may be considered by a clinician. These are not antihistamines and have a different place in therapy.

For nasal symptoms that persist, adding an intranasal corticosteroid may help. These sprays address congestion and inflammation directly in the nose. Choice depends on symptom pattern, age, and tolerance. Always review specific product directions and age limits.

Combination Therapy

Aerius® can be used alone or as part of a plan. For moderate to severe nasal symptoms, an antihistamine plus an intranasal steroid can improve control versus either alone. Some people need an antihistamine for itch and hives and a nasal spray for congestion.

Decongestants such as pseudoephedrine relieve stuffy nose, but they may raise blood pressure or heart rate. Combination products that add decongestant are not right for everyone. Eye drops with antihistamine or mast-cell stabilizer can help allergic conjunctivitis. Non-drug measures, such as saline rinses and avoiding triggers, add benefit.

Patient Suitability and Cost-Saving Tips

Aerius® suits many adults and children with seasonal or perennial allergies and hives. It is helpful when daytime alertness matters, since it is non-drowsy for most people. Those with kidney disease, pregnant or breastfeeding individuals, and people on interacting drugs should review suitability with a healthcare professional.

To save more, consider larger quantities when appropriate. A multi-month supply often reduces the monthly price. Set up reorder reminders so you do not run out during peak pollen season. For current offers and bulk options, check our Aerius coupon page.
