Warnings and precautions

• Take care not to pass on your hepatitis B to other people. You can still infect others when taking this medicine. Vemlidy does not reduce the risk of passing on hepatitis B to others through sexual contact or blood contamination. You must continue to take precautions to avoid this. Discuss with your doctor the precautions needed to avoid infecting others.
• Tell your doctor if you have a history of liver disease. Patients with liver disease, who are treated for hepatitis B with antiviral medicines, have a higher risk of severe and potentially fatal liver complications. Your doctor may need to carry out blood tests to monitor your liver function.
• Talk to your doctor or pharmacist if you have had kidney disease or if tests have shown problems with your kidneys, before or during treatment. Before starting treatment and during treatment with Vemlidy, your doctor may order blood tests to monitor how your kidneys work.
• Talk to your doctor if you also have hepatitis C or D. Vemlidy has not been tested on patients who have hepatitis C or D as well as hepatitis B.
• Talk to your doctor if you also have HIV. If you are not sure whether you have HIV, your doctor should offer you HIV testing before you start taking Vemlidy for hepatitis B.

• If any of these apply to you, talk to your doctor before taking Vemlidy.
