Reaction, allergic precipitating

Immunologic findings in individuals with wood dust-induced asthma also vary. In some cases, a Type 1 allergic reaction is confirmed by the presence of IgE antibodies. Positive skin reactions and the presence of precipitating antibodies to wood dust or extracts may or may not occur.

In susceptibie individuais, NSAIDs may precipitate acute bronchospasm. It affects 10-20% of adults with asthma but is rare in asthmatic children. The mechanism is related to cyclooxygenase inhibition, with shunting of arachidonic acid metabolism from the prostaglandin pathway to the biosynthesis of ieukotrienes with increased mucosal permeability and bronchospasm. Susceptible patients should avoid NSAIDs since the bronchospasm may be severe and has been fatal. Paracetamol in doses up to 1000 mg daiiy wiii be toierated by most patients. True type I allergic reactions to NSAIDs, with specific IgE, are rare but anaphyloactoid reactions have occasionally been described in patients with a history of aiiergy or bronchiai asthma. 

When diphenhydramine was mixed with meglumine iodi-pamide to prevent an allergic reaction to the latter, a precipitate was formed. These two drugs should be regarded as incompatible for in vitro mixing. 

Most parenteral iron is administered intramuscularly, but intravenous injections have enjoyed a wave of popularity for no very good medical reason it seems particularly likely to precipitate acute allergic or anaphylactic reactions in sensitive individuals, sometimes involving cardiac dysrhythmias, hypotension, circulatory collapse, and pulmonary edema. 

The integrity of the blood-retinal and retinal pigment epithehal barriers may be examined directly by retinal angiography using intravenous administration or either fluorescein sodium or indocyanine green. These agents commonly cause nausea and may precipitate serious allergic reactions in susceptible individuals. 

Yes. Allergies to meat derived from certain animals may precipitate allergic reactions to heparin derived from the same source (e.g., beef or pork). In addition, allergies to sulfites may precipitate allergic reactions to heparin that is administered as sulfur conjugates. 

No. These drugs have a sulfonamide structure and cross-sensitivity may precipitate an allergic reaction. 

These drugs cause nausea and vomiting, and can precipitate allergic reactions in penicillin-allergic patients. 

F. Some oral haloperidol tablets contain tartrazine dye, v ich may precipitate allergic reactions in susceptible patients. 

The ability of sex hormones to precipitate an allergic reaction or to influence the immune response is not clear. There are, however, reports suggesting that OCDs, in addition to eliciting allergic reactions, may either adversely affect or improve already existing allergic rhinitis. Some of these reports are included below.
