It's the ultimate ballerina name for me....graceful and swanlike.
I imagine in 15 or 20 year's time, the allergy medicine will be gone, so I wouldn't bypass such a lovely name for that reason only.
Possible middles, in no particular order (sorry for any repeats):
I just keep thinking of the medicine unfortunately
If the allergy medicine association bothers you a bit, what about Allegrea (ah-leg-ree-ah)? My cousin's brother just used that for his newest little girl (his other girl is Annika). She does get the nn "little legs" but she has these long, slender, beautiful legs! HA!
I thought of the allergy medicine first, but then I'm allergic to everything and have been on the vast majority of allergy meds at on e point or another!
Like others said, it's also a musical term. I definitely think it's still usable as a name! (Be prepared for some people to make the medicine connection, though.)
the first thing that comes to mind for me is the allergy medication, which is a shame, because it's lovely.
The first thing I think of is the allergy meds too. Although it is pretty.
