Broadcast regulator Ofcom is investigating Loose Women following an incident that saw Katie Price's disabled son, Harvey, swear on live TV.
Katie's son joined her on the ITV show last month for a segment to discuss internet trolls.
The media watchdog confirmed it had received 10 complaints following the May 17 episode.
An Ofcom spokesman said: "Ofcom is investigating this programme which included the most offensive language before the watershed."
Fourteen-year-old Harvey, whose father is footballer Dwight Yorke, is visually impaired, autistic and suffers from Prader-Willi syndrome.
The NHS describes Prader-Willi syndrome as a "rare genetic condition that causes a wide range of problems", among them "a constant desire to eat, learning difficulties and reduced muscle tone".
Harvey has frequently been the target of online abuse and when asked on the show about people who had targeted him, he used the c-word.
Katie, 38, asked him: "If someone says something horrible to Harvey, what does Harvey say?"
The teen responded: "Hello, c***."
Panellist Andrea McLean apologised numerous times, adding before the show ended: "We have to apologise, obviously, for the language that you heard a little bit earlier on."
During the episode, Katie defended her decision to show the segment with Harvey live, instead of pre-recording it.
She said: "I want people to see what he's like, not manufacture and edit what he's like."
Ofcom further added that in relation to Harvey's welfare, they had received sufficient assurances from ITV that the broadcaster had ensured due care of him, and as such they would not be pursuing any potential issues in this regard any further.
