FAQ
What if HIV infection co-exists with HBV infection? Will this affect treatment with X Vir 1mg?
The use of X Vir 1mg is not recommended in HBV patients who are also diagnosed with HIV, until and unless these patients start taking medicines for HIV management. Starting X Vir 1mg 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 X Vir 1mg.
What is drug resistance? Can I develop drug resistance with X Vir 1mg?
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 X Vir 1mg is more likely to happen if you take less dose than what is recommended.
Can X Vir 1mg cause liver problems?
Yes, X Vir 1mg 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.
Can X Vir 1mg cure hepatitis B?
No, X Vir 1mg 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.

What are the symptoms of serious liver problems?

These symptoms are more common in women, overweight patients, or if you have been on X Vir 1mg for a long time. Immediately contact your doctor if you experience any such symptoms.
