Product introduction

Entecavir is an antiviral medicine used in the treatment of hepatitis B virus (HBV) infection. It works by inhibiting the replication of the virus, thereby reducing its levels in the body. By suppressing viral replication, it helps to slow down the progression of liver damage.

E-Vir Tablet should be taken in an empty stomach. Take it in the exact dose and duration prescribed by your doctor. Follow the instructions carefully. Taking it regularly at the right times greatly increases the effectiveness and help improve liver function, and decrease the risk of complications associated with chronic HBV infection. It is not known whether E-Vir Tablet will reduce your chances of getting liver cancer or liver damage (cirrhosis), which may be caused by chronic HBV infection. Do not miss a dose and keep taking until your doctor tells you it is safe to stop. 
Common side effects of this medicine include headache, nausea, vomiting, stomach pain, fatigue, and diarrhea. These are usually not serious but tell your doctor if they bother you or do not go away. Rarely, some people may experience a skin reaction or liver damage. Your doctor will closely monitor you for these in the initial period of treatment.

Before taking it, tell your doctor if you have any skin problems or kidney disease. While using it, you may need regular blood tests to check your blood counts and liver function. Avoid drinking alcohol as it may increase your risk of liver damage. Pregnant or breastfeeding mothers should consult their doctor before using this medicine. Do not have unprotected sex or share personal items like razors or toothbrushes, if you are HIV positive. Talk to your doctor about safe ways like condoms to prevent HIV transmission during sex.

FAQs

Q. How should E-Vir Tablet be taken?

You should take E-Vir Tablet exactly as prescribed by your doctor and continue taking it till your doctor tells you to stop. 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. It is advised to take it around the same time every day. If not sure, consult your doctor.

Q. Can E-Vir Tablet cause liver problems?

Yes, E-Vir Tablet can cause serious liver problems like hepatomegaly (enlargement of the liver) and steatosis (an increased build-up of fat in the liver). It is important to know that hepatomegaly along with steatosis is a serious medical emergency which requires immediate medical attention.

Q. What are the symptoms of serious liver problems?

The symptoms of liver problems include jaundice (a condition in which your skin or the white part of your eyes turns yellow), dark-colored urine, light-colored stools, loss of appetite, nausea and stomach pain. These symptoms are more common in women, overweight patients, or if you have been on E-Vir Tablet for a long time. Immediately contact your doctor if you experience any such symptoms.

Q. What is drug resistance? Can I develop drug resistance with E-Vir Tablet?

Drug resistance is a state where the medicine which was once effective in treating an infection becomes ineffective. This mainly happens due to the ability acquired by the virus or bacteria to get modified inside the body which affects the overall working of the medicine. Hence, the medicine is no longer able to fight against the virus or bacteria. Generally, drug resistance with E-Vir Tablet is more likely to happen if you take less dose than what is recommended.

Q. How long should I take E-Vir Tablet?

Do not stop taking entecavir without consulting your doctor. Stopping entecavir before treatment may worsen your hepatitis. This can happen during the first several months after you stop taking entecavir. Take the medicine strictly as advised and do not miss any dose.

Q. What if HIV infection co-exists with HBV infection? Will this affect treatment with E-Vir Tablet?

The use of E-Vir Tablet is not recommended in HBV patients who are also diagnosed with HIV, until and unless these patients start taking medicines for HIV management. Starting E-Vir Tablet in such patients may cause resistance to the prescribed HIV medicines. Therefore, doctors recommend tests for HIV in patients diagnosed with HBV infection before starting treatment with E-Vir Tablet.

Q. Can E-Vir Tablet cure hepatitis B?

No, E-Vir Tablet does not cure hepatitis B but may improve the condition of the liver. The medicine may help decrease the amount of hepatitis B virus (HBV) present in the body. This is done by limiting the ability of HBV to multiply and further infect new liver cells.
