An allergy is an exaggerated immune response or reaction to substances that are generally not considered harmful. As an example one can be allergic to hay fever, mold, dust, food and certain medications. Allergic reactions can also be caused by insect bites, jewelry, cosmetics, and almost any substance that contacts the body. Some people have allergic-type reactions to hot or cold temperatures, sunlight, or other physical stimuli, such as friction (rubbing or vigorously stroking the skin). The goal of antiallergy medications is to reduce the symptoms caused by inflammation of the affected tissues. Below you may find a list of anti allergy medications available for sale in Singapore and Malaysia.
