An allergen is any substance that may cause an allergic reaction. So if an individual has an allergy to penicillin then penicillin is the stimulus for that individuals allergic reaction and PCN is an allergen but only for that individual. So any substance including nuts, pollen and drugs can act as an allergen. The key point is that allergens will only cause an allergic reaction in a person whose body perceives that substance as foreign but not for the general population.
