Product introduction

Tavin EM Tablet is not a cure for HIV/AIDS and only helps to decrease the amount of HIV in your body. This helps lower your risk of getting HIV-related complications and improves your lifespan. It may also be used to prevent HIV infection in some people at high risk. It may be prescribed alone or in combination with other HIV medicines. Your doctor will recommend the best medicines for you and will decide the doses that you need. Carefully follow the instructions for all the medicines that you are given. Taking these medicines regularly at the right time greatly increases their effectiveness and reduces the chances of HIV becoming resistant to them. It is important not to miss doses and to keep taking them until your doctor tells you it is safe to stop.


Common side effects of this medicine include nausea, diarrhea, headache, trouble sleeping, rash, and dizziness. These are usually not serious, but inform your doctor if they bother you or do not go away. It can also increase the risk of bone loss (osteoporosis) if you take it for a long time. Exercise regularly and take calcium and vitamin D supplements as suggested by your doctor. Some people put on weight while taking medicines to treat HIV/AIDS.


Before taking it, let your doctor know if you have any liver or kidney disease or bone problems. While using it, you may need regular blood tests to check your blood counts, liver function, and kidney function. Since this medicine may cause dizziness or sleepiness, do not drive if you experience these symptoms. Pregnant or breastfeeding women 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.
