Multiple drugs: Gastrointestinal side effects, nausea, drug misuse and lack of efficacy.

A 30-year-old woman experienced gastrointestinal side effects and nausea while being treated for generalized plaque psoriasis and chronic hepatitis B infection. She also did not respond well to several medications for her psoriasis and misused some of them.

However, she eventually discontinued tenofovir due to nausea. [Extracted from the article]
