Y43.0: Antiallergic and antiemetic drugs

The term "Antiallergic and antiemetic drugs" refers to medications that are used to manage or prevent allergies or nausea and vomiting, respectively. The Pharmaceutical substances classified under this category help reduce symptoms of allergic reactions such as sneezing, itching, and rash. They can also keep the body from reacting to allergens, substances that cause an allergic response. Antiemetic drugs are primarily designed to prevent or reduce nausea and vomiting, which can be symptoms of various conditions like migraines, flu, food poisoning, or side effects of certain medications. While these drugs are essential in managing symptoms, they can lead to adverse reactions or complications as well, particularly when not used correctly. This may include symptoms like dizziness, blurred vision, or gastrointestinal discomfort among others. In severe cases, these drugs can cause serious health issues requiring medical intervention.
