What should I tell my doctor before starting treatment with Allegra 180mg Tablet?
It is important to inform your doctor about any existing medical conditions and medications. This includes kidney disease, as dose adjustments may sometimes be needed while taking Allegra 180mg Tablet. Also mention if you are pregnant, planning a pregnancy, or breastfeeding. Providing a complete list of prescription or non-prescription medicines to your doctor helps identify potential interactions.
What if I forget to take a dose of Allegra 180mg Tablet?
If you miss a dose, take it when you remember. However, if it is nearly time for the next scheduled dose, skip the missed dose. Do not take two doses at the same time. Since Allegra 180mg Tablet is usually taken once daily, maintaining a consistent schedule helps ensure symptom control.

It is always better to consult your doctor and provide a list of all prescription and non-prescription medicines before taking Allegra 180mg Tablet.

Can I stop taking Allegra 180mg Tablet if I feel better?
Take Allegra 180mg Tablet exactly as directed to help manage your allergy symptoms. This medicine relieves the signs of an allergic reaction but does not treat the underlying cause; therefore, you can stop it when your symptoms have improved. If your symptoms recur after stopping the medicine or persist despite treatment, contact your doctor for further evaluation.
Is Allegra 180mg Tablet an antibiotic?
No. It is not an antibiotic; it is an antihistamine. Antibiotics treat bacterial infections, whereas antihistamines like Allegra 180mg Tablet relieve allergy symptoms by blocking the effects of histamine in the body.

What is the best time of day to take Allegra 180mg Tablet?
Allegra 180mg Tablet is usually taken once daily. It can be taken at any time of day, but taking it at the same time each day helps maintain consistent symptom control. Some people prefer taking it in the morning for daytime allergy symptoms.
