A viral infection is different than an allergy. It is, as the name implies, an infection with a virus, whereas an allergy is a reaction of your body's immune system to a substance; it is not an infection.
Viral infections are not treated with antibiotics, and most are short-lived. If it's itching you might try a topical itching ointment. Otherwise, leave it alone to heal. If it persists for more than a month, check back with your doctor.
