When cold and flu season hits, you might find yourself juggling multiple symptoms. If you are a regular user of Allegra (fexofenadine) for allergies, you may wonder if it is safe to combine it with over-the-counter (OTC) cold and flu medications. Understanding these interactions is vital for your health.

What is Allegra?
Allegra is a non-drowsy antihistamine used to treat allergic rhinitis. Unlike older antihistamines, it is specifically designed to block histamine receptors without crossing the blood-brain barrier significantly, which is why it typically does not cause the sedation associated with other allergy drugs.
Can You Mix Them?
In general, yes, you can often take Allegra with many cold medicines, but with significant caveats. Because Allegra is non-drowsy, it is often safer to combine than diphenhydramine (Benadryl). However, you must avoid “doubling up” on active ingredients.
Crucial Precautions:
- Check for Antihistamines: Many multi-symptom cold medicines (like NyQuil or DayQuil) already contain antihistamines (e.g., chlorpheniramine or doxylamine). Taking Allegra on top of these can increase the risk of side effects like dry mouth, urinary retention, or dizziness.
- Decongestants: Medications containing pseudoephedrine or phenylephrine are generally safe to take with Allegra. However, if you have high blood pressure, be cautious, as decongestants can raise your heart rate and blood pressure.
- Avoid Alcohol: Never mix cold medications with alcohol, as this increases the risk of impaired judgment and excessive drowsiness.
When to Consult a Doctor
Before mixing medications, always read the “Drug Facts” label. If you are pregnant, elderly, or have chronic conditions like heart disease or glaucoma, consult your pharmacist or physician first.
A Note on Emergency Symptoms
While managing cold symptoms, it is important to stay vigilant about your overall health. Though unrelated to cold medicine, sudden symptoms such as facial drooping, slurred speech, or weakness on one side of the body are warning signs of a stroke. If you or a loved one experience these, seek emergency medical help immediately. Every second counts in medical emergencies.
