How Allegra Works
Fexofenadine works by blocking the H1 histamine receptors in the body. When an allergen triggers the immune system, histamine is released and binds to these receptors, causing allergic reaction symptoms. Allegra reduces the severity of allergy symptoms by preventing histamine from attaching to these receptors.
Unlike older antihistamines, which often cause drowsiness by affecting the brain, fexofenadine selectively targets the peripheral histamine receptors and has little to no effect on the central nervous system. This makes Allegra a non-sedating antihistamine that can be used during the day without the concern of feeling tired or drowsy.
Uses and Benefits
Allegra is primarily used to treat the following:
- Seasonal Allergies (Hay Fever): Allegra helps relieve symptoms such as sneezing, runny or itchy nose, itchy or watery eyes, and itching of the throat or roof of the mouth caused by hay fever (allergic rhinitis).
- Chronic Urticaria (Hives): Allegra effectively treats chronic urticaria, a condition characterized by itchy, red hives. This can occur due to allergic reactions or other factors.
- Non-Drowsy Relief: The 180 mg dose provides long-lasting, 24-hour relief without causing drowsiness, making it suitable for daily use during allergy seasons or for individuals experiencing chronic allergic reactions.
- Safe for Long-Term Use: Allegra’s formulation is suitable for daily use, providing consistent relief without the need for frequent re-dosing.
- Quick Onset of Action: The effects of Allegra are typically felt within one hour of taking the medication, making it a fast-acting solution for allergy symptoms.
Side Effects
As with any medication, Allegra may cause side effects in some individuals. These are usually mild and tend to subside as your body adjusts to the medication. However, it is essential to be aware of potential side effects:
- Difficulty breathing or swallowing
- Swelling of the face, throat, lips, or tongue (signs of an allergic reaction)
- Fast or irregular heart rate
- Severe dizziness or fainting
If any of these serious side effects occur, you should seek medical help immediately.
Recommendations for Use and Safety Precautions
To ensure the best possible results and safety when using Allegra, follow these guidelines:
- Take as Directed: The typical dose for adults and children over 12 years old is one 180 mg tablet once daily. The tablet should be taken with water and can be taken with or without food.
- Avoid Overuse: Do not take more than the recommended dose, as doing so could increase the risk of side effects.
- Use with Caution if Pregnant or Breastfeeding: Allegra should be used during pregnancy or breastfeeding only if necessary and as advised by a healthcare provider.
- Consult Your Doctor: If you have a history of kidney problems, speak with your healthcare provider before using Allegra, as dose adjustments may be necessary.
- Alcohol Consumption: While Allegra is non-sedating, it’s still a good idea to limit alcohol consumption, as it can exacerbate side effects like dizziness and drowsiness.
- Children Under 12: Allegra 180 mg is generally not recommended for children under 12. A doctor’s recommendation is necessary for younger children, and a lower dose may be more appropriate.
