The active ingredient in Mizollen is mizolastine. Mizolastine
is an antihistamine.
Mizollen is used to reduce the symptoms of:

• other allergic reactions causing irritation of the eyes and
nose (perennial allergic rhinoconjunctivitis)
• urticaria (an itchy skin rash, like nettle rash).

ingredients of this medicine (listed in section 6)
if you are taking a macrolide antibiotic (such as
erythromycin, clarithromycin, azithromycin)
if you are taking an imidazole antifungal medicine (such
as ketoconazole, fluconazole, itraconazole, used to treat
fungus infections)

if you have heart problems
if you have ever had an irregular heart beat or a slow
heart rate
