POLLINEX Grasses and Rye Initial/Extension Course is a form of allergen immunotherapy specifically designed for individuals who suffer from allergies to grasses and rye pollen. This treatment aims to desensitize the immune system to these allergens, potentially reducing the severity of allergic reactions or even preventing them altogether. The course typically involves a series of injections that are administered over a period of time, starting with an initial dose followed by extension doses to boost the immune system's tolerance. By gradually exposing the immune system to increasing amounts of the allergen, POLLINEX Grasses and Rye can help alleviate allergic symptoms such as sneezing, nasal congestion, and itchy eyes, improving the quality of life for those affected by grass and rye pollen allergies.
