Indications 

Vemlidy is a prescribed medication for adults with stable (compensated) liver disease to manage chronic hepatitis B virus (HBV) infection. 

Classified as a nucleoside reverse transcriptase inhibitor (NRTI), Vemlidy works by inhibiting the replication of the hepatitis B virus within the body. This action may lead to a reduction in HBV levels and potential liver improvement. 

Uses and Dosage 

Before starting Vemlidy treatment, HIV-1 testing is essential, as this medication should not be used as a standalone therapy for patients with HIV-1 infection. 

Review the medication guide and patient information leaflet of Vemlidy before taking it and with every prescription refill. For any inquiries, consult your doctor or pharmacist. 

The dosage of this medication is determined based on the patient’s medical condition, treatment response, and concurrent medications. 

Typically, Vemlidy is taken once daily with food as prescribed by the doctor. 

Patients receiving dialysis should take Vemlidy following their dialysis sessions. Maintaining a regular dosing routine is essential to ensure no doses are skipped. 

If vomiting happens within 1 hour after a dose, take an additional dose. If vomiting occurs more than 1 hour after the dose, do not take an extra dose; instead, adhere to your regular dosing schedule for the next dose. 

Adhere strictly to the prescribed dosage of Vemlidy and refrain from altering it, discontinuing, or deviating from the treatment plan unless specifically instructed by your doctor. Such actions could exacerbate the infection, increase resistance, or intensify side effects.
