Can i use 10mg of loratadine on a regular basis?

Yes: This medication is safe to use regularly. If you are on other medications or have any chronic illness, kidney, or liver problems check with your own doctor about your specific issues first.

Yes but: No harm buy taking it regularly but it is not a good idea to take a medication indefinitely without a definite diagnosis. If you need it throughout the year I will recommend allergy testing done by an allergy and immunologist. Take a drug holiday every now and then, do not take it for few days in a row and see what happens. This info will help allergy specialist.
