FDA approves Vemlidy
The U.S. Food and Drug Administration (FDA) has approved Vemlidy (tenofovir alafenamide, TAF) 25mg, a once-daily hepatitis B virus (HBV) nucleoside analog reverse transcriptase inhibitor indicated for the treatment of adults with chronic HBV infection with compensated liver disease.

Important information
Vemlidy can cause serious side effects, including:
Build-up of lactic acid in your blood (lactic acidosis).
Lactic acidosis may happen in some people who take this medicine, or similar medicines. Lactic acidosis is a serious medical emergency that can lead to death.
Lactic acidosis can be hard to identify early, because the symptoms could seem like symptoms of other health problems. Call your healthcare provider right away if you get any of the following symptoms which could be signs of lactic acidosis:
feel very weak or tired
have unusual (not normal) muscle pain
have trouble breathing
have stomach pain with nausea or vomiting
feel cold, especially in your arms and legs
feel dizzy or lightheaded
have a fast or irregular heartbeat
Severe liver problems. Severe liver problems may happen in people who take Vemlidy. In some cases, these liver problems can lead to death. Your liver may become large (hepatomegaly) and you may develop fat in your liver (steatosis). Call your healthcare provider right away if you get any of the following symptoms of liver problems:
your skin or the white part of your eyes turns yellow (jaundice)
dark tea-colored urine
light-colored bowel movements (stools)
loss of appetite
nausea
pain, aching, or tenderness in the right side of your stomach area
You may be more likely to get lactic acidosis or severe liver problems if you are female, very overweight (obese), or have been taking this medicine or a similar medicine for a long time.
Worsening of hepatitis B infection. Your hepatitis B (HBV) infection may become worse (flare-up) if you start treatment, and then stop. A flare-up is when your HBV infection suddenly returns in a worse way than before.
Do not run out of this medicine. Refill your prescription or talk to your healthcare provider before your pills are all gone.
Do not stop taking this medicine without first talking to your healthcare provider.
If you stop taking this medicine, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your HBV infection. Tell your healthcare provider about any new or unusual symptoms you may have after you stop treatment.
