Tenvir-EM for PrEP – Side Effects

Anti-HIV meds are the ultimate remedies helping millions of HIV-1 infected people. Individuals afflicted with this virus go through various medical challenges caused by weaker immune function. However, there are easily available and cost-effective ways to address this condition with the use of anti-HIV meds like Tenvir-EM tabs.

Tenvir-EM, an antiretroviral drug from Cipla Pharmaceuticals, is a daily med taken along with other safer sex practices to reduce the risk of becoming infected. It’s also important to be fully informed about safe sex and HIV infection methods. In most cases, you should conduct follow-ups while under PrEP treatment. You’re required to visit your doctor or healthcare provider every 12 weeks for testing. Where in doubt, ask your doctor for advice.

HIV usually attacks the body’s white blood cells (also known as CD4+ cells) – immune cells that play a vital role in protecting and fighting external harmful infections that find opportunities to enter into the body. When these cells are attacked, the immune system becomes weaker making other external harmful opportunistic viruses (infections) to easily enter your body. As the CD4+ becomes weaker and weaker, the HIV-1 replicates and spread faster resulting in AIDS.

The function of Tenvir-EM is to prevent the virus by slowing down the potential of HIV-1 from replicating and spreading. It strengthens the immune system by increasing the number of CD4+ cells and keeping the number of virus low – making the virus pose a reduced risk of disease development.

While it’s an effective drug for PrEP with higher efficacy and tolerability, there are some side effects and drug reactions (as discussed below) which you must know when using this medication. At HIVPrEP, we only give you detailed and educative resources to help you be informed while using Tenvir-EM.
