What is the most important information I should know about tenofovir (Viread)?


Do not take tenofovir together with adefovir (Hepsera), or with combination medicines that contain tenofovir (Atripla, Complera, or Truvada).


Tenofovir should not be given to a child with HIV who is younger than 2 years old. Tenofovir should not be used to treat hepatitis B in anyone younger than 18 years old.


Some people develop lactic acidosis while taking tenofovir. Early symptoms may get worse over time and this condition can be fatal. Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, fast or uneven heart rate, dizziness, or feeling very weak or tired.


Tenofovir can also cause severe or life-threatening effects on your liver. Call your doctor at once if you have any of these symptoms while taking tenofovir: nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes).


If you have hepatitis B you may develop liver symptoms after you stop taking this medication, even months after stopping. Your doctor may want to check your liver function for several months after you stop using tenofovir. Visit your doctor regularly.


HIV/AIDS is usually treated with a combination of drugs. Use all medications as directed by your doctor. Do not change your doses or medication schedule without your doctor's advice. Every person with HIV or AIDS should remain under the care of a doctor.
