If Vemlidy has been prescribed for your child, please note that all the information in this leaflet is addressed to your child (in this case please read “your child” instead of “you”).
Vemlidy contains the active substance tenofovir alafenamide. This is an antiviral medicine, known as a nucleotide reverse transcriptase inhibitor (NtRTI).
Vemlidy is used to treat chronic (long-term) hepatitis B in adults and children 6 years of age and older, who weigh at least 25 kg. Hepatitis B is an infection affecting the liver, caused by the hepatitis B virus. In patients with hepatitis B, Vemlidy controls the infection by stopping the virus from multiplying.
If this applies to you, do not take Vemlidy and tell your doctor immediately.
If any of these apply to you, talk to your doctor before taking Vemlidy.
There is a possibility that you may experience kidney problems when taking Vemlidy over a long period of time (see Warnings and precautions).
Do not give this medicine to children who are under 6 years old, or weighing less than 25 kg. Vemlidy has not been tested in children aged less than 6 years old or weighing less than 25 kg.
Bone problems. Loss of bone mass has been reported in some children who received Vemlidy. The effects on long-term bone health and future fracture risk in children are uncertain. Your doctor will monitor this possible risk. Tell your doctor if any bone pain or fractures occur.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. Vemlidy may interact with other medicines. As a result, the amounts of Vemlidy or other medicines in your blood may change. This may stop your medicines from working properly, or may make any side effects worse.
