The two most common causes of swollen lips are injuries and allergic reactions.

The cause that probably requires a doctor's attention more than any other is the reaction to certain kinds of high blood pressure medications, specifically ACE-inhibitors, including benazepril (Lotensin), captopril (Capoten), enalapril (Vasotec), fosinopril (Monopril), lisinopril (Prinivil, Zestril), quinapril (Accupril), ramipril (Altace), and trandolapril (Mavik).

If you're taking these or anything similar and your lip swells up, call your prescriber and tell them about it before you have an episode in which your tongue swells up and your throat and air passages are blocked by runaway swelling. This often happens to patients whose lip swells up, although not necessarily at the same time. Ask the doctors or other prescribers if you should stop taking that particular medication (they will usually tell you to do so and replace it with a different kind of blood pressure med). They may even put you on a one-week detoxification program.
