Hello and welcome to Healthcare Magic. Thanks for your query.

LCZ (Levocetrizine) and Allegra (Fexofenadine) are anti-allergy medication which are called "anti-histamines". They act by preventing the release of allergy-mediating chemicals called "histamines"

These anti-allergy medication do not cause any addiction and generally, there would be no necessity to keep increasing the medication as time goes by. However, usually, these medication are prescribed for short periods only, with the hope that the body will slowly get 'sensitized' or adjusted to the allergen and will be able to tackle it without the necessity of the medication.

Both LCZ and Allegra are usually prescribed as once daily doses, because their duration of action is roughly one day - i.e. the optimum effects of the medication last for one day. But in your case, you mention that one tablet is effective for 4 days. If you are comfortable taking Allegra once a day, then it should be quite okay. There is no hard and fast rule that they have to be taken daily.

Wish you all the best.

Hi rashma,
Welcome to healthcare Magic!
There is a norm for the practicing doctors, there are treatment schedules of drugs for diseases called Regimens. They are decided upon by the apex hospitals of developed countries like America/Britain/Australia/Japan.
The idea for giving a medicine thrice in a day is to win over the disease, the once in a 4day thing will also work but will take a life time probably.
No one would like to live with a disease for life.
Try to get it diagnosed soon and manage under physician supervision.
There is more harm in self styled changes of medication schedule than good, simply avoid it.
I hope the advise would be informative and useful for you.
Take Care!
