I think the most popular brands are being sold all over the world, under different names. In Sweden they are nowadays all OTC in small packs. All the popular brands have essentially the same effect so any of them will do.

Go by the generic names of the substance, for example loratadin or cetirizin.

As tablets have a systemic effect, they will have an impact on symptoms in all potentially affected organ systems, in this case mostly the upper airways - nose, throat and eyes.

By the same coin, they will very often not suffice. Typically one needs to add a local medicine - like antihistamine eye drops and nasal steroid spray for optimal effect.

Try it daily for a week or two, make an appointment with a doc. It will be very useful information for the doc, whether the medicine have had any effect or not.
