Boxed warning

EXACERBATIONS OF HEPATITIS B, AND DIFFERENT FORMULATIONS OF LAMIVUDINE.

Exacerbations of Hepatitis B Severe acute exacerbations of hepatitis B have been reported in patients who are co-infected with hepatitis B virus (HBV) and human immunodeficiency virus (HIV-1) and have discontinued lamivudine. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue lamivudine and are co-infected with HIV-1 and HBV. If appropriate, initiation of anti-hepatitis B therapy may be warranted [see Warnings and Precautions (5.1)]. Important Differences among Lamivudine-Containing Products Lamivudine tablets (used to treat HIV-1 infection) contain a higher dose of the active ingredient (lamivudine) than EPIVIR-HBV tablets and oral solution (used to treat chronic HBV infection). Patients with HIV-1 infection should receive only dosage forms appropriate for treatment of HIV-1 [see Warnings and Precautions (5.1)]. […]

What does the patient leaflet for lamivudine say first?

The FDA-approved Medication Guide or Patient Information that comes with the medicine, in its own words.

From the patient leaflet: What is the most important information I should know about lamivudine tablets?

Lamivudine tablets can cause serious side effects, including: Worsening of hepatitis B virus in people who have HIV-1 infection. If you have HIV-1 (Human Immunodeficiency Virus type 1) and hepatitis B virus (HBV) infection, your HBV may get worse (flare-up) if you stop taking lamivudine tablet. A "flare-up" is when your HBV infection suddenly returns in a worse way than before. Worsening liver disease can be serious and may lead to death. Do not run out of lamivudine tablets. Refill your prescription or talk to your healthcare provider before your lamivudine tablets is all gone. Do not stop lamivudine tablets without first talking to your healthcare provider. If you stop taking lamivudine tablets, your healthcare provider will need to check your health often and do blood tests regularly for several months to check your liver.
