Adult Swim’s Common Side Effects has taken the animated world by storm with its unique blend of dark humor, conspiracy-driven storytelling, and surreal visuals. Since its Season 1 premiere in February 2025, fans have been buzzing about the possibility of a second season. Here’s everything we know so far.
Common Side Effects Season 2 Renewal Confirmed
Adult Swim officially renewed Common Side Effects for a second season on March 28, 2025, just before the Season 1 finale aired. The announcement came as no surprise, given the show’s critical acclaim, strong viewership on Adult Swim and Max, and enthusiastic fan support on social media.
Season 2 Release Date Speculation
While Adult Swim has confirmed the renewal, an official release date for Common Side Effects Season 2 has not been announced. Based on the production timeline of Season 1, which took roughly 18 months from its June 2023 announcement to its February 2025 premiere, industry experts speculate a potential release in late 2026, possibly around September or October.
The intricate animation style and serialized storytelling require significant production time, typically 12–18 months for high-quality animated series. However, recent updates from the Annecy International Animation Film Festival in June 2025 revealed that the first script for Season 2 is complete, and the team described the upcoming season as “tight,” suggesting progress is underway.
Where to Watch Common Side Effects
Season 1 of Common Side Effects is available to stream on Max and airs on Adult Swim, with encore broadcasts on the Toonami programming block.
