I have an allergy to dust , dust mites and grass should i take an antihistamine every day ?

Address the cause: Taking antihistamines daily is one option -however, additional interventions are important. Though it is impossible to avoid allergens, many physicians will recommend minimizing your exposure to them by using air purifiers, using rugs rather than wall to wall carpeting, using hypoallergenic bedding and minimizing outdoor activities during specific times of the year when pollen counts are high.
