Drug
Lamivudine
Pronounced
"la-MIV-ue-deen"
Uses
This drug is used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life. Lamivudine belongs to a class of drugs known as nucleoside reverse transcriptase inhibitors-NRTI.
Lamivudine is not a cure for HIV infection. To decrease your risk of spreading HIV disease to others, continue to take all HIV medications exactly as prescribed by your doctor. Use an effective barrier method (latex or polyurethane condoms/dental dams) during sexual activity as directed by your doctor. Do not share personal items (such as needles/syringes, toothbrushes, and razors) that may have contacted blood or other body fluids. Consult your doctor or pharmacist for more details.
Warning
If you have hepatitis B infection along with HIV, your hepatitis symptoms may get worse or become very serious if you stop taking lamivudine. Talk with your doctor before stopping this medication. Your doctor will perform liver function tests for several months after you stop lamivudine. Tell your doctor right away if you develop symptoms of worsening liver problems.
Different brands of this drug have different amounts of drug. Do not switch brands of this medication without first checking with your doctor. If you have HIV infection (with or without hepatitis B infection), you should be taking the higher-strength dosage. Consult your doctor or pharmacist.

Skipping or changing your dose without approval from your doctor may cause the amount of virus to increase, make the infection more difficult to treat (resistant), or worsen side effects.
