When you or someone you know is prescribed the Zidovudine (ZDV) vaccine as a treatment for HIV, it's normal to feel a little apprehensive and curious. "What is this medicine?", "What will happen with this?", "Are there any side effects?" are a lot of questions that may come to mind. So today, let's understand this medicine called Zidovudine very simply, as if we were talking to a friend.
What kind of medicine is Zidovudine (ZDV)?
Simply put, Zidovudine is an antiretroviral medicine . It is a type of medicine used to treat HIV infection. However, it is not used alone, it is usually given in combination with several other medicines used for HIV.
The main function of this medicine is to control the spread of the HIV virus in the body, that is, the multiplication of the virus. Through this, it reduces the damage to the body's immune system and helps you live a healthy life.
But this is very important: Zidovudine is not a cure for HIV. But it can help control the virus. Also, it is important to remember that while taking this medicine can reduce the risk of passing HIV to others, it does not eliminate the risk completely.
