Frequently asked questions about Tenofovir disoproxil fumarate
Q. Does Tenofovir disoproxil fumarate prevent passing of HIV-1 and HBV to others?
In case of HIV-1 infection, Tenofovir disoproxil fumarate may reduce the risk of passing the virus to others, but the chances of infecting others still persist. However, in case of HBV infection, Tenofovir disoproxil fumarate has not proven to reduce risk of transferring the virus to others. Therefore, the patients of both HIV-1 infection and HBV infection should practice safe sex and should not share dirty needles.
Q. Is Tenofovir disoproxil fumarate safe?
Tenofovir disoproxil fumarate 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.
Q. How should I take Tenofovir disoproxil fumarate?
You should take Tenofovir disoproxil fumarate in the dose and duration advised by your doctor. Tenofovir disoproxil fumarate works best when taken with meals or just afterwards. However, taking it without food does not reduce its effectiveness. If you have any doubts, consult your doctor.
Q. For how long do I need to take Tenofovir disoproxil fumarate for HBV infection?
Duration of treatment will depend on the severity of HBV infection. You will need to take periodic blood tests to keep a check on the viral load and number of T cells. Your doctor will then decide the duration of the medicine accordingly. In some cases, treatment is required life long.
Q. I vomited after taking Tenofovir disoproxil fumarate. What should I do?
Take another tablet of Tenofovir disoproxil fumarate if you vomit within 1 hour of taking it. If you vomit after more than an hour of taking Tenofovir disoproxil fumarate, then you need not take another tablet. Consult your doctor if you have vomiting every time you take Tenofovir disoproxil fumarate or if the vomiting persists for a longer duration.
Q. What should I do if I forget to take Tenofovir disoproxil fumarate?
If you forget to take Tenofovir disoproxil fumarate within 12 hours of the time you usually take it, you should take Tenofovir disoproxil fumarate with food as soon as possible and resume the normal dosing schedule.

Frequently asked questions about Lamivudine
Q. How should I take Lamivudine?
Lamivudine 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.
Q. Is Lamivudine effective?
Lamivudine 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 Lamivudine too early, the symptoms may return or worsen.
Q. What is drug resistance? Can I develop drug resistance with Lamivudine?
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 Lamivudine is more likely to happen if you take less dose than what is recommended.
Q. How long should I take Lamivudine?
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 I forget to take a dose of Lamivudine?
If you forget a dose of Lamivudine, 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.
Q. What if HIV infection co-exists with HBV infection? Will this affect treatment with Lamivudine?
In HBV patients who are diagnosed with HIV, Lamivudine is not recommended until and unless these patients start taking medicines for HIV management. Starting Lamivudine 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 Lamivudine.
Q. Can Lamivudine cure hepatitis B?
No, Lamivudine 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.
Q. Is Lamivudine safe?
Lamivudine 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.
