LONDON (Reuters) -Men at the sex shop said they bought 50 tablets of Viagra for £14.99 and had ordered 10,000 more for a total of 30,000.

He said: "If you are buying a drug that is to be sold under the brand name Viagra, you are going to see some very worrying data and the use of erectile dysfunction drugs in the UK. And as a result, we will be monitoring and assessing the potential for this to affect patients.

"Erectile dysfunction is a very common condition that affects many men and could lead to significant health care costs for some people."

The Medicines and Healthcare products Regulatory Agency (MHRA) is warning patients to avoid using the medicine if they are over the age of 18.

"The Medicines and Healthcare products Regulatory Agency (MHRA) is also recommending that patients stop taking or using the erectile dysfunction drug and seek advice from their GP or another healthcare professional if they have been diagnosed with erectile dysfunction," said spokesman Tom McKillop.

The MHRA said the advice to patients had been given to other prescribers by health officials.

Meds Health Chief Medical Officer Simon Clark told the BBC: "We're aware of the concerns raised by the Medicines and Healthcare products Regulatory Agency (MHRA), but we're working with other groups to raise the alarm about this.

"We're aware of the concerns raised by the Medicines and Healthcare products Regulatory Agency (MHRA) and we're making these recommendations to provide more clarity for patients and the public about the potential impact on their health."

The MHRA is also advising patients to stop using the erectile dysfunction drug if they have a serious heart or blood vessel disease.

The Medicines and Healthcare products Regulatory Agency (MHRA) said it was investigating the case.

The MHRA had previously said the risk of heart attacks and stroke was "very low" in people taking the medicine and in people taking nitrates.
