Drug Uses
Epivir interferes with the HIV virus's ability to reproduce in the human body and delays the breakdown of the human immune system. It is also used for treatment of chronic hepatitis B.
How it is taken
Epivir must be taken exactly as prescribed by your doctor. You must continue to take it even if you have started feeling better. You may take it with or without food.
Missed Dosage
If you miss a dose of Epivir then you may take it as soon as you remember and adjust the remaining doses accordingly. However, if it is nearly time for the next dose then you may skip this dose and continue with the regular dosage. Do not take a double dose to make up for the missed dose.
Overdose
If you suspect an overdose, seek medical attention immediately.

You must not take Epivir if you are allergic to any ingredient in it or if you are taking zalcitabine or other medicines containing lamivudine.
If you are pregnant or suspect that you are, then stop using Epivir and contact your doctor immediately.
If your medicine supply starts to run out, then get a refill immediately or maintain an ample stock. Because the virus can get very difficult to control if you stop the dosage even for a while.

Use barrier forms of contraception (eg, condoms) if you are infected with HIV. Do not share needles, other injection equipment, or personal items such as toothbrushes or razor blades.
Cases of worsening liver disease have been reported when Epivir is stopped in patients with both HIV and hepatitis B virus infection.
If you have hepatitis B virus infection, your doctor will perform lab tests for several months after you stop taking Epivir.
Some patients have had worsening hepatitis B virus after stopping use of Epivir. Tell your doctor about any new or unusual symptoms that you notice after stopping treatment. Epivir may affect your blood sugar.
Certain drugs can interact with and hence, mention clearly to your doctor or pharmacist all medicines, dietary supplements and herbal prescriptions that you are taking.
