Tenvir-EM, manufactured by the Indian company Cipla, is a generic of the well-known medicinal product Truvada from the USA. Tenvir includes two active antiviral substances Tenofovir (300 mg) and Emtricitabine (200 mg). The medicine is licensed and approved by doctors around the world to cure the human immunodeficiency virus (HIV). They also recommend buying it and using it for patients with AIDS in the early stages. Thanks to the active antiviral components Tenofovir and Emtricitabine, the biological product, once it enters the patient’s body, begins to resist Tenvir-EM by lowering the quantitative value of infected bodies and inhibiting the future development and replication of the microbe in the infected body. Studies and laboratory tests have shown its positive effects and positive response to treatment, however, it is recommended to buy and use the analog of Truvada only after the diagnosis and delivery of the necessary tests and examinations with the infectious disease doctors. The price of Tenvir-EM is much lower than that of the official Truvada, but the effectiveness of the existing medicines Emtricitabine and Tenofovir in it is absolutely the same, the difference is only in the country of manufacture.
