Understanding Fexofenadine

Fexofenadine is a second-generation antihistamine primarily used to relieve the symptoms of seasonal allergies, such as hay fever. Unlike older antihistamines, fexofenadine is less likely to cause drowsiness, making it a preferable choice for those needing to maintain alertness during the day.

Antihistamines work by blocking histamines, substances your body releases during an allergic reaction. This action helps mitigate symptoms such as sneezing, itching, watery eyes, and a runny nose.

How Fexofenadine Works

Fexofenadine works by blocking the H1 receptor. Histamine in the body attaches to these receptors during an allergic reaction, causing symptoms. By blocking these receptors, fexofenadine effectively reduces the symptoms associated with allergies.

• Reduces allergic reactions: Fexofenadine soothes inflammation and other allergy symptoms.
• Minimal penetration to the brain: This characteristic reduces drowsiness, making it different from first-generation antihistamines.

Common Uses of Fexofenadine

Fexofenadine is used to treat various allergy-related conditions. Some of the most common conditions include:

• Seasonal Allergies (Hay Fever): Helps relieve symptoms like runny nose and watery eyes.
• Chronic Idiopathic Urticaria: Provides relief from persistent hives and itching.

• Adults and children over 12: 60mg twice daily or 180mg once daily.
• Children aged 6-12: 30mg twice daily.

Always follow a healthcare professional’s advice and do not exceed the recommended dosage.

Potential Side Effects

While fexofenadine is generally safe, potential side effects exist.

• Common side effects: Include headache, dizziness, and nausea.
• Rare but severe side effects: Could be an allergic reaction to the drug itself, presenting symptoms like rash, itching, swelling, severe dizziness, and trouble breathing.
