Generic Allegra 180mg (fexofenadine hydrochloride) is typically administered once daily. Take it with a glass of water.
Important Considerations
- Timing: You can take it with or without food. However, consistency is key; choose a time that works best for your routine and stick to it. Missed Dose: If you miss a dose, take it as soon as you remember, unless it’s almost time for your next dose. Never double the dose. Kidney Disease: If you have kidney problems, your doctor may adjust your dosage. Always inform them of your medical history.
Potential Interactions
While generally well-tolerated, fexofenadine can interact with certain medications. Discuss all your current medications, including over-the-counter drugs and supplements, with your doctor or pharmacist.
Antacids containing aluminum or magnesium can reduce Allegra’s absorption. Space out the administration of these medications by a few hours. Ketoconazole and erythromycin can increase fexofenadine levels. Your doctor might recommend dosage adjustments.
Always follow your doctor’s instructions and read the medication guide provided with your prescription. Contact your doctor or pharmacist if you have questions or concerns.
