When you have contact with any allergen, your body produces histamines. These chemicals then trigger swelling, itching, rashes and hives.
Therefore, doctors often choose antihistamines to treat allergies. As the name shows, antihistamines can reduce histamines so as to eliminate the symptoms.
If you have hives, drugs containing antihistamines will help stop itching, swelling and other hives symptoms. However, if these do not work, your doctor will prescribe you other drugs.
