can you take allergy medicine for a cold?
Most experts say that histamine isn't the major cause of a runny nose when you have a cold. Even so, some of the older antihistamines, such as brompheniramine and chlorpheniramine, can bring relief. Newer antihistamines like fexofenadine (Allegra) and loratidine (Claritin) have not been shown to work for cold symptoms.
