-- A hack of the World Anti-Doping Agency has drawn attention to commonly prescribed medications that are prohibited for use during the Olympics without a medical waiver.
Biles, 19, took to Twitter today to say she was not ashamed of her condition.
While stimulants are a banned substance, medications used for ADHD may be allowed if an athlete gets a medical waiver. And although stimulants in people without ADHD can make them feel hyperactive or laser focused, the drugs help people with ADHD rein in their hyperactivity and diminishes distractibility. WADA officials no longer ask athletes to cease treatment for a competition because symptoms are best controlled with consistent daily usage.
Medical experts point out that the drug is one of many common over-the-counter and prescription drugs that athletes must either avoid or get a waiver to take.
Pseudoephedrine, commonly found in the cold and flu medication Sudafed, is banned on the day of competition. The drug is a stimulant and can make athletes more alert for a competition.
If an athlete is battling a cold or flu, the U.S. Anti-Doping Association advises athletes to stop taking the drugs a few days before they compete.
Albuterol, used to treat asthma, may not be used in conjunction with a diuretic without a medical waiver. The drug has been used by athletes to build muscle mass.
