Prophylaxis = treatment for disease
There is no cure for HIV once it has established itself in the body. However, if taken within 72 hours (3 days) of exposure to the HIV virus PEP can, in most cases, prevent it from establishing itself in the body.
It takes a few days for HIV to become established in the body following exposure. PEP drugs given at this time may help the body's immune system to stop the virus from replicating (multiplying) in the infected cells of the body. The cells originally infected would then die naturally within a short period of time without producing more copies of the HIV virus.
Not if you act quickly. After HIV gets in the bloodstream it takes some time before it permanently establishes itself in the body. If a person who has been exposed to the virus acts quickly (within 72 hours) they stand a chance of stopping the virus from establishing itself in their body.Top of page
