UFC’s Mayra Bueno Silva suspended, has Holly Holm win overturned after positive drug test for ADHD med

Top UFC women’s bantamweight contender Mayra Bueno Silva has received official punishment from the Nevada Athletic Commission (NAC) after she tested positive for a banned substance during a urine test conducted in connection with her July 15 victory over Holly Holm.

Mayra Bueno Silva, a leading contender in the UFC women’s bantamweight division, has been subjected to sanctions by the Nevada Athletic Commission (NAC) following a positive urine test for a prohibited substance. The test was administered after her triumph over Holly Holm on July 15.

While Bueno Silva previously disclosed her positive test for ritalinic acid, both she and the commission have now formalized the disciplinary measures at a monthly NAC meeting. She has been handed a 4.5-month suspension, an $11,250 fine amounting to 15% of her purse, and has incurred legal costs of $314.50.

Bueno Silva’s victory over Holm in the main event at UFC on ESPN 49 has been overturned to a no contest. Bueno Silva emerged triumphant by submitting Holm in the second round.

MMA Junkie received confirmation of the official ruling from a reliable source well-versed in the matter, following an initial report by MMA Fighting.

Since revealing her positive drug test result, Bueno Silva has attributed it to her use of Concerta, a medication prescribed for ADHD. Ritalinic acid is a metabolite of Concerta (methylphenidate).

Bueno Silva expressed gratitude towards the commission and her supporters for their understanding and support throughout the process.

Irrespective of the ultimate outcome of the Holm bout, Bueno Silva maintains that the drug did not enhance her performance in any way.

“I take this medication because my mind is very hyperactive. If I don’t take this medication, I won’t be able to focus. It’s not beneficial for training or fighting. It has no effect on my performance,” Bueno Silva shared with MMA Junkie in August.

Bueno Silva clarified that her dispute lies solely with the Nevada Athletic Commission and explained that neither the UFC nor USADA sought punitive action against her. Bueno Silva hopes for changes in the policies concerning ADHD medications and their metabolites going forward.

“I believe these regulations need to be revised to accommodate individuals with ADHD. This revision is essential. If I can serve as an example for this cause, I’m willing to do it, but the change is necessary,” Bueno Silva asserted.
