News: Pollen allergy.

Pollen allergy is common but fortunately it is safe to treat allergy symptoms even during pregnancy. The primary choice for local symptoms is a topically administered medicine available in pharmacies over the counter. In oral antihistamines, loratadine or desloratadine are the primary choice, as well as fexofenadine. Cetirizine and levocetirizine are secondary options. Products that are safe to take during pregnancy are also safe to use when you are breastfeeding. Further information on this topic (Allergy and asthma)
