- a history of pancreatitis; or
- if you have used a medicine similar to lamivudine in the past, such as abacavir (Ziagen), didanosine (Videx), emtricitabine (Atripla, Complera, Emtriva, Truvada), stavudine (Zerit), tenofovir (Viread), zalcitabine (Hivid), or zidovudine (Retrovir).
Some people develop a life-threatening condition called lactic acidosis while taking lamivudine.

Talk with your doctor about your individual risk.

Tell your doctor if you are pregnant or plan to become pregnant during treatment. Take all of your HIV medicines as directed to control your infection.
Lamivudine can pass into breast milk and may harm a nursing baby. You should not breast-feed while you are using lamivudine to treat hepatitis B. Women with HIV or AIDS should not breast feed a baby. Even if your baby is born without HIV, the virus may be passed to the baby in your breast milk.
If you are pregnant, your name may be listed on a pregnancy registry. This is to track the outcome of the pregnancy and to evaluate any effects of lamivudine on the baby.
