What should I discuss with my healthcare provider before taking tenofovir (Viread)?
Do not use this medication if you have ever had an allergic reaction to a medicine containing tenofovir, including Truvada.
To make sure you can safely take tenofovir, tell your doctor if you have any of these other conditions:
Some people develop a life-threatening condition called lactic acidosis while taking tenofovir. You may be more likely to develop lactic acidosis if you are overweight or have liver disease, if you are a woman, or if you have taken HIV or AIDS medications for a long time. Talk with your doctor about your individual risk.
Tenofovir can also cause severe or fatal liver problems. Symptoms include nausea, stomach pain, low fever, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes). Call your doctor at once if you have any of these symptoms.
FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby, but HIV can be passed to your baby if you are not properly treated during pregnancy. Take all of your HIV medicines as directed to control your infection.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of tenofovir on the baby.
Women with HIV or AIDS should not breast-feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
Tenofovir should not be given to a child unless your doctor has told you otherwise.
How should I take tenofovir (Viread)?

HIV/AIDS is usually treated with a combination of drugs. Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. 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.
To be sure this medicine is helping your condition and is not causing harmful effects, your blood will need to be tested often. Your liver and kidney function may also need to be tested. Visit your doctor regularly.
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.
