Phenylephrine is a common ingredient in cough and cold drugs, used to treat nasal congestion. It is a decongestant that works by narrowing the blood vessels in the nasal passages, reducing swelling and congestion. It is available in both over-the-counter and prescription medications, and is often combined with other ingredients such as antihistamines, expectorants, and pain relievers. It is also used in combination with other drugs to treat sinus infections, allergies, and other respiratory conditions. Phenylephrine is generally considered safe and effective when used as directed, but it can cause side effects such as dizziness, headache, and nausea. It is important to follow the instructions on the label and speak to a doctor if any side effects occur. Some companies that produce cough and cold drugs containing phenylephrine include Johnson & Johnson, GlaxoSmithKline, Pfizer, and Novartis. Show Less Read more
