i am currently taking oxybutynin 5mg. one a day. Had signs of a cold coming on, running nose, cought, etc. took a Mucinex-DM 12 hr. tablet. h woke the next morning with my lips swallen. Next day my right side of my face was drooping, eyes watering, . went to Dr. today and he said i had a alergigic reaction to something. I didn t think of the Mucinex till after I got home and was trying to think of what i took to cause this reaction. can you tell me if taking both of these caused this reaction?
