It is best to wait till morning for the next dose- details below

Detailed Answer:
Hello and welcome to 'Ask A Doctor' service,

I carefully read your query and understand your concern.

Allegra 24 contains all the dose of Fexofenadine you need in 24 hours, so the next pill can be taken only after 24 hours. It is best to wait till morning before you get another dose of fexofenadine.

If you have symptoms of severe allergy, swelling of lips, or eyes or shortness of breath you will need to see your doctor as soon as possible. Otherwise, waiting till morning to take the next dose is the safest approach.

I hope this answers your query.
I remain at your disposal in case further medical assistance is needed.

Regards
