when the action of these proteins is decrease the production of HIV slows.
3TC interferes with a compound named reverse transcriptase
(RT) that is utilized by HIV- infected cells to make new infection viruses. From
the 3TC inhibits, or decrease, the action of this enzyme, this medication
causes HIV--infected cells to make less HIV.
How do individuals with HIV use 3TC?
