Over-the-counter drugs that can boost blood pressure

People with high blood pressure should avoid certain popular over-the-counter drugs used to treat cold and flu symptoms and pain. The problematic products are those that contain decongestants such as oxymetazoline, pseudoephedrine, and phenylephrine; and nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen sodium. Because drugstores contain an overwhelming number of products that feature those drugs, people should ask their pharmacist to recommend a product.
