ITIA four-year tour ban
Following a provisional suspension, in October 2025 Oliveira was issued with a four-year ban by the International Tennis Integrity Agency backdated to January 2025 for an anti-doping rule violation after testing positive for methamphetamine. The test was taken at an ATP Challenger event in Manzanillo, Mexico in November 2024. Oliveira argued that he came into contact with the substance following a kiss but after a review, an independent tribunal ruled that he could not prove that his exposure to the drug was unintentional and issued the ban on 10 October 2025. His results from 25 November 2024 onwards were disqualified.ATP Challenger and ITF Tour finals
