Sudafed is a decongestant medication that is available over the counter. It works to relieve nasal and sinus congestion by stimulating certain receptors known as alpha-adrenergic receptors in the lining of the nose and sinuses. The medication comes in the form of immediate-release tablets, extended-release tablets, and a liquid. While most people tolerate it well, potential side effects include insomnia, rapid heart rate, and nervousness.
