Final answer:
Two methods to prevent latex allergic reactions include avoiding direct contact by using latex-free alternatives and undergoing desensitization therapy under medical supervision.
Step-by-step explanation:
To prevent latex allergic reactions, two effective methods are to avoid direct contact with latex products and to use latex-free alternatives. For individuals who cannot avoid latex exposure due to their professional responsibilities, it is advisable to use non-latex gloves and other latex-free medical supplies. Additionally, to minimize the chances of an allergic reaction, one can take steps such as avoiding oil-based lubricants which can degrade latex and being cautious not to invert or spill latex products like condoms.
Desensitization therapy is another method to prevent allergic reactions to latex. This involves receiving injections of dilute concentrations of latex allergens in gradually increasing amounts, to help the immune system become accustomed to it and reduce hypersensitivity reactions. This treatment must be performed under strict medical supervision due to the risk of severe reactions.
