This makes it particularly useful in managing conditions like allergic rhinitis and hives. Additionally, Bamirastine can be applied topically or taken orally, providing flexibility in its administration based on the severity and type of allergic response. Its fast-acting nature ensures quick relief, making it a reliable option for individuals seeking immediate alleviation of allergic symptoms.
