Baraclude (Entecavir) is used to treat long-term hepatitis B infection. Hepatitis B is an infection of the liver caused by the hepatitis B virus. Long-term infection can cause liver damage, rarely liver cancer, and liver failure. Entecavir helps to decrease the amount of hepatitis B virus in your body. It is unknown if this medication lowers your chance of getting liver cancer or liver damage. Entecavir is an antiviral that belongs to a class of drugs known as hepatitis B virus nucleoside reverse transcriptase inhibitors.
Entecavir is not a cure for hepatitis B. It does not prevent the spread of the virus to others through sexual contact or blood/body fluid contamination (such as sharing used needles).
WARNINGS: Rarely, entecavir may cause serious (possibly fatal) liver problems and lactic acid build-up in the blood (lactic acidosis). Get medical help right away if you have any of the following symptoms: nausea/vomiting that doesn't stop, loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine, unusual tiredness/weakness, deep/fast breathing, unusual drowsiness, unusual muscle pain, feeling cold in your arms/legs, fast/irregular heartbeat. These side effects may occur more often in women and obese patients.
Your hepatitis B infection may get worse if you stop taking entecavir. Do not stop this medication without talking to your doctor. Your doctor will do blood tests to check your liver for several months after you stop entecavir.
This medication is not recommended if you have both HIV and hepatitis B and are not receiving effective treatment for HIV. This drug does not treat HIV, and it can cause certain HIV medications to become ineffective. Get an HIV test before starting this medication, and get tested again anytime you may have become infected. Consult your doctor for more details.
