Real Housewives of Beverly Hills alum Teddi Mellencamp, who's battling stage 4 melanoma skin cancer, was left fighting for her life after she had an allergic reaction to a medication, RadarOnline.com can reveal.
The 44-year-old daughter of hitmaker John Mellencamp was recently hospitalized after being diagnosed with Stevens-Johnson syndrome, a rare, potentially fatal disorder of the skin and mucous membranes.
Teddi Mellencamp’s Health Scare Horror
Teddi Mellencamp recalled urgent care telling her: 'You need to go to the ER right now.'
"I hadn't felt good for a couple of days," the wellness coach recounted. "I thought I had the flu. And then I woke up one day, and my whole body was just covered in this terrible rash. You can't even say it's a rash because there's almost like sores all over my entire body."
"And [the sores] hurt and they burned," she continued.
"And, so, I went to the urgent care first, hoping they would just be, like, 'Oh, you're having an allergic reaction.' And the urgent care doctor immediately was like, 'No, you need to go to the ER right now.'"
Doctors discovered that she was allergic to a medication she had started taking, which had caused the severe, painful blisters.
"It went into my mouth," Teddi said. "Around my eyes a little bit. It was just everywhere. And then I couldn't swallow."
Hospitalized Mom Fears Missing Birthday
Mellencamp worried she would miss Dove's sixth birthday during hospitalization.
In the hospital, she received steroids and antibiotics and started to feel better within a couple of days.
But adding to her agony was the worry that she wouldn't get out of the hospital in time to celebrate her daughter Dove's sixth birthday.
She'd missed her birthday last year when she was also hospitalized, so she was especially anxious to attend this year.

Teddi was diagnosed with stage 2 melanoma in March 2022, then in April 2025, she shared that it had grown to stage 4 and had spread to her brain and lungs.
