Why is this medication prescribed?
Allegra-D, which contains the active ingredients fexofenadine and pseudoephedrine, is typically prescribed for the treatment of seasonal allergic rhinitis (hay fever) in adults and children aged 12 years and older.
How should this medicine be used?
Allegra-D is a medication that combines fexofenadine and pseudoephedrine. It is typically used to relieve symptoms of seasonal allergies (such as hay fever) and nasal congestion.
Here are general guidelines for using Allegra-D:
- Dosage: Follow the dosage instructions provided by your doctor or as indicated on the packaging. Typically, it is taken once daily.
- Timing: It’s usually taken in the morning with a full glass of water to prevent potential insomnia due to pseudoephedrine, which can be stimulating.
- Swallowing: Swallow the tablet whole; do not crush, chew, or break it, as it is formulated for extended release.
- Avoiding Certain Substances: Avoid taking Allegra-D with fruit juices (especially grapefruit, apple, or orange juice) as they may interact with the absorption of fexofenadine.
- Consultation: Always consult your healthcare provider or pharmacist before starting Allegra-D, especially if you have any existing medical conditions or are taking other medications.
- Duration: Use Allegra-D for the duration recommended by your healthcare provider, even if your symptoms improve.
- Side Effects: Be aware of potential side effects such as headache, nausea, insomnia, or dry mouth. If you experience severe side effects or an allergic reaction (difficulty breathing, swelling of the face/lips/tongue), seek medical help immediately.
- Storage: Store Allegra-D at room temperature away from moisture and heat.
Remember, Allegra-D is a controlled substance due to the pseudoephedrine component, so it should be used responsibly according to the directions provided. If you have any doubts or questions, it’s best to seek advice from your healthcare provider or pharmacist.
Other uses for this medicine
- Chronic Rhinitis: In some cases, Allegra-D may be prescribed for chronic rhinitis or non-allergic rhinitis where nasal congestion is a prominent symptom.

What special precautions should I follow?
When using Allegra-D, it’s important to take special precautions to ensure safe and effective use:
- Medical History: Before starting Allegra-D, inform your healthcare provider about your complete medical history, especially if you have conditions such as high blood pressure, heart disease, thyroid problems, diabetes, glaucoma, prostate problems, or kidney disease.
- Drug Interactions: Notify your doctor about all other medications you are currently taking, including prescription drugs, over-the-counter medicines, herbal supplements, and vitamins. Some medications may interact with Allegra-D, particularly other decongestants or antihistamines.
- Pregnancy and Breastfeeding: Consult your doctor before using Allegra-D if you are pregnant or breastfeeding. Pseudoephedrine can pass into breast milk and may have undesirable effects on a nursing infant.
- Age Considerations: Allegra-D is generally not recommended for children under 12 years old due to the risk of serious side effects from pseudoephedrine. Use in older adults should be approached cautiously due to potential cardiovascular effects.
- Side Effects: Be aware of potential side effects such as headache, insomnia, dizziness, dry mouth, nausea, or increased blood pressure. If you experience severe or persistent side effects, consult your doctor.
- Dosage: Follow the dosage instructions provided by your healthcare provider or those on the product label carefully. Do not exceed the recommended dose or duration of treatment unless instructed by your doctor.
- Monitoring: Your doctor may need to monitor you closely while you are taking Allegra-D, especially if you have underlying medical conditions.
- Discontinuation: Do not stop taking Allegra-D suddenly without consulting your doctor, as this could lead to withdrawal symptoms or a rebound effect.
By following these precautions and guidelines, you can help ensure safe and effective use of Allegra-D for its intended purposes under medical supervision. Always discuss any questions or concerns with your healthcare provider before starting or modifying treatment with Allegra-D.
What special dietary instructions should I follow?
There are no specific dietary restrictions associated with Allegra-D. However, it’s generally recommended to take the medication with a full glass of water to ensure proper absorption, and to avoid taking it with fruit juices, especially citrus juices, as they can interfere with the absorption of pseudoephedrine.
What should I do if I forget a dose?
If you miss a dose of Allegra-D, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one.
