Can you have an allergic reaction to alcohol just by smelling it?

People with alcohol allergies might also experience allergic reactions just from the smell of alcohol, which is related to individual physical constitutions. Generally, alcohol allergies occur after contact with alcohol or after consuming it. However, individuals with poor health and an allergic constitution might experience allergic reactions when exposed to the smell of alcohol, such as chest tightness, shortness of breath, dizziness, and fatigue. In such cases, it is advisable to immediately leave the environment where the alcohol smell is present and rest in a place with good air circulation and drink more water. If the symptoms do not improve, it is necessary to seek further medical treatment at a hospital. Regularly drinking more water and exercising appropriately to strengthen the physique is recommended, and if necessary, visiting a hospital to check for allergens might be needed.

Can drug allergies be tested for allergens?

Drug allergies do not require allergen testing because drug allergies are allergic reactions caused after taking medications, with fairly clear causes, eliminating the need for allergen testing. Allergens are the causes of allergic reactions. If the cause of an allergy is unclear, it is necessary to go to a hospital to check for allergens. The main focus of allergen testing includes food, pollen, etc., but this is unnecessary for medications. Commonly, skin testing can be conducted for medications to see if any allergic reactions occur. If there is an allergic reaction, the medication should not be used again. If the medication must be used, desensitization methods can be adopted to provide drug treatment.

Alcohol allergy causes

Alcohol allergy, also known as ethanol allergy, occurs because normally, ethanol in the body is converted into acetaldehyde. People with alcohol allergies lack the enzyme needed to convert acetaldehyde, therefore cannot expel acetic acid from the body, resulting in acetaldehyde poisoning and various allergic symptoms. People who can consume large amounts of alcohol usually have a higher amount of this acetaldehyde converting enzyme, allowing them to quickly convert it without experiencing poisoning or allergic symptoms. Alcohol allergies are mostly linked to an allergic constitution; thus, individuals with this constitution will display various allergic symptoms upon exposure to alcohol, the allergen.
