Can I swallow it with juice?
Use water. Apple, orange and grapefruit juices can reduce absorption; do not use fruit juice to take it.
Can I take my antacid at the same time?
Avoid taking aluminum- or magnesium-containing antacids close to fexofenadine. Ask the pharmacist to set the spacing for your products.
Is every Allegra product once daily?
No. Strength, formulation and age change the directions. Follow your exact label.
Sources: MedlinePlus; fexofenadine labeling.
Does the form change how I take it?
Shake suspension before measuring with a medicine device. Peel dissolving tablets from the foil with dry hands just before use; let them dissolve on your tongue. Check your product's food instructions. MedlinePlus
What if I miss a dose?
For scheduled use, take it when remembered unless the next is nearly due; then skip it. Never double. MedlinePlus
What should the pharmacist check?
Mention kidney disease, pregnancy, breastfeeding and the child's age. Headache, nausea or drowsiness can occur. Do not add another antihistamine without advice. MedlinePlus
When is it urgent?
Severe breathing trouble or tongue/throat swelling needs emergency help. Fexofenadine is not emergency treatment for a severe allergic reaction. MedlinePlus
