Table of contents:

Vemlidy is a prescription medicine used to treat chronic (long-lasting) hepatitis B virus (HBV) in adults and children 12 years of age with stable (compensated) liver disease. Vemlidy does not cure hepatitis B virus infection, and it is not known if it can prevent the spread of the virus to others. It contains the active ingredient tenofovir alafenamide, which is a nucleoside analog reverse transcriptase inhibitor.

Tenofovir works by stopping the hepatitis B virus in the liver from multiplying. It is prescribed to be activated in the liver, and once there, it interferes with the normal working of an enzyme (DNA polymerase) that is essential for the virus to replicate and multiply. This slows down the virus's ability to spread in the body and can help reduce the amount of hepatitis B virus in the blood. As a result, Vemlidy can help to improve liver inflammation and reduce the risk of serious liver-related complications in people with chronic hepatitis B.

Uses and Dosage

Vemlidy is a tablet taken orally, usually once daily with or right after a meal, or as directed by your doctor. Swallow the tablet whole with a glass of water and do not break, divide, or chew this medication. If you are on dialysis, take this nucleoside analog after your dialysis treatment.

The recommended dosage for Vemlidy in adults and pediatric patients who are 12 years of age and older is 25 mg (one tablet) taken orally once daily with food. The dosage for patients with renal impairment may be different - it is not recommended in patients with end stage renal disease who require dialysis. As with any medication, please consult with your healthcare provider for personalized dosage instructions.

Take Vemlidy regularly and on a dosing schedule to achieve the best results. The dosing and length of treatment will depend on your medical condition, response to treatment, and other medications you are taking. Do not adjust your dosage without consulting a healthcare professional. Do not stop taking Vemlidy abruptly, even for a brief time, as this can lead to worsening or drug-resistant infections.
