Frequently asked questions
Lamuvid 100mg Tablet should be taken in the dose and duration advised by the doctor. This medicine can be taken with or without food. However, it is better to take it at a fixed time of the day to avoid the chances of missing a dose.
Lamuvid 100mg Tablet is effective if used in the dose and duration advised by your doctor. Do not stop taking it even if you see improvement in your condition. If you stop using Lamuvid 100mg Tablet too early, the symptoms may return or worsen.
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 Lamuvid 100mg Tablet is more likely to happen if you take less dose than what is recommended.
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.
If you forget a dose of Lamuvid 100mg Tablet, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take the next scheduled dose in the prescribed time. Do not double the dose to make up for the missed one as this may increase the chances of developing side effects.
In HBV patients who are diagnosed with HIV, Lamuvid 100mg Tablet is not recommended until and unless these patients start taking medicines for HIV management. Starting Lamuvid 100mg 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 Lamuvid 100mg Tablet.
No, Lamuvid 100mg Tablet does not cure hepatitis B but may improve the condition of the liver. It may 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.
Lamuvid 100mg Tablet is safe if used in the dose and duration advised by your doctor. Take it exactly as directed and do not skip any dose. Follow your doctor's instructions carefully and let your doctor know if any of the side effects bother you.
