Is it possible for topical hemostatic agents cause any allergic reaction?

Yes: Any topical substance can potentially cause an allergic reaction. This is commonly known as contact dermatitis. If the reaction occurs after repeated exposure, it is most likely allergic. If it occurs on the very first exposure, it is probably an irritant reaction (irritant contact dermatitis).

Possible: It is possible for any medication that one use's to cause an allergic reaction, an adverse drug reaction or to have side effects.
