The Food and Drug Administration (FDA) has cautioned the doctors against over-prescription of testosterone-boosting drugs for men, calling the treatment methods unsafe.
According to the federal agency, the commonly-used treatments are not established as effective or safe for common age-related woes such as fatigue and low libido.
The FDA said that the pharmaceutical companies should clearly detail about the effects and use of the drugs in their labeling as well as promotions. The drug is only approved for treating low testosterone levels which is caused due to any injury or disease, and not normal aging.
The testosterone-boosting drugs are currently used by millions of American men.
The FDA also warned against the use of drugs, saying it may raise the risk of stroke, heart attack and several other cardiovascular problems.
The regulatory agency said that the drug makers must include detailed information about the potential risk posed by such medications on their prescribing labels.
Moreover, the drug makers are also suggested to conduct a long-term research for examining the health problems related to it.
Last July, Canada health officials had issued a similar medical warning about the risks posed by testosterone.
