An allergic rash is a quite common skin condition for many people. This is because nowadays people are reacting to or have a greater sensitivity to allergens than they every did in the past. Even very small amounts or very small exposures to allergens can trigger an allergic reaction characterized as an allergy rash.
Individuals may experience an allergic skin rash for many reasons. People may have an allergy to medications is one of the main reasons. In fact, the most common medications that lead to a skin rash are antibiotics such as penicillin. Codeine is another medication that often causes a rash on the skin. In reality, individuals can experience an allergic reaction with any medication but the above two are the most common.
Certain foods can often lead to a rash. When a person has a food allergy, such as a nut allergy, a common symptom is an allergic skin rash. As is the case with medications, the list of foods that may cause problems is endless and whether an allergic reaction occurs really depends on the specific individual. This type of reaction is difficult to diagnose and careful attention has to be paid to the foods consumed and potentially those consumed together. An allergic food reaction may not occur immediately, thus making it even harder to diagnose in some cases.
A skin rash on the body may also result from spider bites, insect bites or insect stings, contact with poisonous plants such as poison ivy or poison oak, or contact with various environmental and chemical allergens that people may encounter in their daily routines.
Basically, it is very difficult to isolate the exact cause of a skin rash initiated by an allergic reaction. Careful attention must be paid to when the rash first appeared and whether it can be linked to a specific drug, food, etc.
If a skin rash due to an allergy occurs, it should not be taken lightly. This is especially true if the individual that has developed the skin rash does not appear to be physically well. In particular, when a person with the skin problem is having difficulty breathing, speaking, is incoherent, or is unconscious, then emergency medical attention is required immediately. Severe allergic reactions can lead to death and therefore any allergic rash needs to be carefully monitored and emergency aid obtained if more serious symptoms develop. The rash on the skin may simply be the first indicated of the onset of a more serious health issue.
