Is it an allergic reaction if my face is very swollen after using Dymista?

An allergic reaction cannot be excluded. The drug Dymista - like any product - can provoke such a response of the body. According to the documentation: "You should seek medical attention immediately if you experience any of the following symptoms: swelling of the face, lips, tongue or throat, which may cause difficulty swallowing and/or breathing, and sudden appearance of a skin rash. These may be signs of a severe allergic reaction." There is also a note that these symptoms are very rare. However, it cannot be ruled out that they affected you.
