Antihistamines such as diphenhydramine (Benadryl), hydroxyzine (Visatril), and cetirizine (Zyrtec) are often helpful in managing and preventing episodes of angioedema.
Why do you give FFP for angioedema?
Therefore, the rationale for using FFP in ACEI-associated angioedema is that it contains kininase II, which is similar to angiotensin-converting enzyme and catalyzes the degradation of excessive bradykinin, thus rendering it ineffective.
