Kate Moss' sister Lottie, 26, has issued an urgent warning after being rushed to hospital as a result of overdosing on weight loss drug Ozempic.
The model opened up about how she became violently ill and suffered a seizure after a friend bought her the drug from a doctor.
She took high doses of the drug, which has been popularised in Hollywood, when she weighed around 60kg.
Moss has since opened up about being hospitalised as she said she would "rather die" than use the drug, which is supposed to treat obesity or diabetes, again.
Her seizure was caused by severe dehydration, with Moss admitting it had been one of the "scariest" experience she had faced.
She said there were "small things I wish I'd known before taking it" and that her weight fell to 53kg within a few weeks.
After she was seen by medical professionals, Lottie was told the dosage she'd injected should be prescribed to someone weighing at least 100kg, almost double her size.
She stated: "A few months ago, I was not feeling happy about my weight, I had a friend, and she could get it for me.
"It was below board, from a doctor, but it wasn't like you go into a doctor's office and he prescribes it for you, takes your blood pressure, and takes tests, which is what you need when you go on something like Ozempic.
"At the end of the day it is a medication, it is dangerous and really meant for weight loss of people of a very large size.

"When I was taking it, the amount that I was taking was meant for people who are 100kg and over and I'm in the 50s range.
"It's these small things I wish I'd known before taking it. But I took it, you inject it into your leg, and it was the worst decision I ever made.
"This is a warning to everyone. Please, if you're thinking of taking it, do not take it, it's so not worth it.

Speaking on her podcast Dream On, Moss continued: "I would rather die any day than take it again. It made me feel so nauseous.
"I took it for two weeks. It comes with a pen and different doses, you take one injection one week, one injection the next week and you take every week, and I've never felt sicker in my life."
