Warning over Lamar Odom 'herbal Viagra'

People are being warned not to take a pill linked to Lamar Odom's collapse in a brothel.

Khloe Kardashian's husband was found unconscious at Love Ranch in Nevada.

The brothel's owner, Dennis Hof, told Newsbeat the basketball star "was doing herbal supplements, herbal Viagra if you will, and he was doing a lot of it".

The US Food and Drug Administration (FDA) says such "sexual enhancement" products are "dangerous".

Proper Viagra is medicine for men who have problems having an erection - only a doctor can prescribe it.

The FDA says products sold in shops or online claiming to be "herbal" alternatives to Viagra contain substances such as sildenafil which can react badly with other medications you might be taking, causing things like "dangerously low blood pressure".

The packaging often doesn't make it clear what is in these "herbal" products, making it difficult for buyers to know if they are putting themselves in danger.

"Consumers should stop using this product immediately and throw it away," says the FDA website. Any side effects should be reported to your doctor "as soon as possible".

The NHS in the UK has made similar warnings in the past.

Police in Nevada have said Lamar took up to 10 pills in a three-day period, which the brothel says he bought at its shop. In a 911 emergency call, workers at the brothel also said they thought Lamar had used the illegal drug cocaine.

The 35-year-old NBA player is on life support in a hospital, surrounded by family and friends. It's still not clear what caused him to become ill.

Lamar and Khloe filed for divorce in 2013, but still need a judge to formally declare their marriage over.
