Viread Oral Warning
Rarely, tenofovir has caused a severe (sometimes fatal) liver and blood problem (lactic acidosis). Immediately tell your doctor if you develop symptoms of liver problems (persistent nausea, stomach/abdominal pain, dark urine, yellowing eyes/skin), or of lactic acidosis (rapid breathing, drowsiness, muscle aches).
If you have hepatitis B infection along with HIV, your hepatitis symptoms may get worse or become very serious if you stop taking tenofovir. Talk with your doctor before stopping this medication. Your doctor will perform liver function tests for several months after you stop tenofovir. Tell your doctor immediately if you develop symptoms of worsening liver problems.
