My husband started taking oxybutynin & 2 weeks later he got thrush like symptoms. His tongue swelled, the top of his mouth felt super smooth, the sides of his mouth felt coarse, & his lips swelled & were red & chapped. He said everything he tried to eat tasted & felt like wet sand. Because of this, he stopped eating everything but chicken broth for several days. It is the fifth day of all of this & he says it still has not gotten any better & still cannot eat. I went with him to the doctor & she thought he might have thrush. Do you have any thoughts on this, even though I know it is difficult because you cannot see him?
