What is R-Tanna?
Chlorpheniramine reduces the effects that histamine has on the body. Histamine can cause symptoms such as sneezing, itching, and watery eyes. Phenylephrine shrinks the blood vessels of the nasal passages. Dilated blood vessels can cause congestion in the nasal passages. R-Tanna, a combination medication, is used to treat the symptoms of the cold and seasonal allergies. These include sneezing, a runny nose, or watery eyes. R-Tanna can be used in other ways not mentioned in this guide.
