Testim contains the hormone testosterone in a gel. It works by increasing testosterone to a normal level. Testim is used as a skin gel because it would have little effect on testosterone levels if taken orally. When medications are taken by mouth, they must first pass through the liver before they reach the bloodstream (the liver would metabolize the testosterone before it reached the bloodstream).
Before you start using Testim, the prescribing information should be reviewed in order to help minimize risks. Since Testim can rub off onto others with skin-to-skin contact, even hours after it is applied, it is important to take measures to avoid exposing women and children to the drug, as virilization (the development of male characteristics) may occur. You should also be aware that Testim may cause a number of side effects. Potential side effects to look out for during the treatment process include:
