You might try a Z pack...most people tolerate it well...just be sure to eat with it...and it only is a 5 day regimen. I took it for years with no trouble until 2 years ago...so now it's on the "no" list with penicillin, tetracycline and sulfa drugs.

Also, if you are allergic to ragweed, don't take the echinacea...it's a member of the ragweeed family.
