According to medical researchers at Vanderbilt University Medical Center, most people can safely take products containing pseudoephedrine. Dr. Italo Biaggioni, Professor of Medicine and Pharmacology at the Vanderbilt Clinical Trials Center, notes that some patients may not know they are susceptible to the drug's effects when they take over-the counter medications. At typical doses of 30 milligrams, there's only a slightly chance that pseudoephedrine will raise blood pressure. Extended-release allergy and cold medications, however, can have up to four times that amount, or 120 milligrams. Many allergy and cold medications contain pseudoephedrine; it's not only in Claritin and Claritin D.
