Entecavir

Entecavir can cause serious or life-threatening damage to the liver and a condition called lactic acidosis (a buildup of acid in the blood). The risk that you will develop lactic acidosis may be higher if you are a woman, if you are overweight, or if you have been treated with medications for hepatitis B virus (HBV) infection for a long time. Tell your doctor if you have or have ever had liver disease. If you experience any of the following symptoms, call your doctor immediately: yellowing of the skin or eyes; dark-colored urine; light-colored bowel movements; difficulty breathing; stomach pain or swelling; nausea; vomiting; unusual muscle pain; loss of appetite for at least several days; lack of energy; extreme weakness or tiredness; feeling cold, especially in the arms or legs; dizziness or lightheadedness; or fast or irregular heartbeat.

Do not stop taking entecavir without talking to your doctor. When you stop taking entecavir, your hepatitis may get worse. This will most likely happen during the first several months after you stop taking entecavir. Take entecavir precisely as directed. Be careful not to miss doses or run out of entecavir.If you experience any of the following symptoms after you stop taking entecavir, call your doctor immediately: extreme tiredness, weakness, nausea, vomiting, loss of appetite, yellowing of the skin or eyes, dark-colored urine, light-colored bowel movements, or muscle or joint pain.

Suppose you have human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) that is not being treated with medications and you take entecavir. In that case, your HIV infection may become more challenging to treat. Tell your doctor if you have HIV or AIDS or if there is a chance that you have been exposed to HIV. Your doctor may test you for HIV infection before you begin treatment with entecavir and at any time during your treatment if there is a chance that you have been exposed to HIV. Entecavir will not treat HIV infection.

Keep all appointments with your doctor and the laboratory before, during, and a few months after your treatment with Entecavir. Your doctor will order specific tests to check your body’s response to entecavir during this time.

Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.

Talk to your doctor about the risks of taking entecavir.

Inflated pharmaceutical prices are another huge factor in the steep cost of healthcare. Americans spend an average of $858 per person on prescription drugs, according to Vox. That’s about twice as much as people in Australia spend on prescriptions. It’s three times the amount paid by people in The Netherlands.

🔔 Why is this medication prescribed?

Entecavir is used to treat chronic (long-term) hepatitis B infection (swelling of the liver caused by a virus) in adults and children two years of age and older who have liver damage. Entecavir is in a class of medications called nucleoside analogs. It works by decreasing the amount of hepatitis B (HBV) in the body. Entecavir does not cure HBV and may not prevent complications of chronic hepatitis B, such as liver cirrhosis or liver cancer. Entecavir does not prevent the spread of HBV to other people.

🔔 How should this medicine be used?

Entecavir is a tablet and solution (liquid) to take by mouth. It is usually taken once a day on an empty stomach, at least 2 hours after a meal and at least 2 hours before the next meal. Take entecavir at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take entecavir precisely as directed. Do not take more or less of it or more often than your doctor prescribes.

1. Hold the spoon that came with your medication upright and slowly fill it with entecavir solution up to the mark that matches your dose.
2. Hold the spoon with the volume marks facing you and check that the top of the liquid is level with the mark that matches your dose.
3. Swallow the medication right from the measuring spoon. Do not mix the medication with water or any other liquid.
4. Rinse the spoon with water after each use and allow it to air dry.
5. Put the spoon in a safe place where it will not get lost because you must use it every time you take your medication. If you do lose the dosing spoon, call your doctor or pharmacist.
