A North Korean medicine maker has been accused of trying to sell a new drug for the treatment of erectile dysfunction, a drug used to treat cancer. South Korean President Park Geun-hye said Wednesday that the state-run Blue House was considering whether to ban the sale of Viagra, a popular over-the-counter drug used to treat altitude sickness.
The Blue House is concerned that the drug's use could be associated with a surge in sales of Viagra, the drug used to treat altitude sickness, in the late 1990s. Park also said the country is in the midst of a presidential election this year.
Park also said the country's current president, Park Geun-hye, has no plans to take Viagra, although he is expected to sign a letter of impeachment against the president.
Park's office said the Blue House is "in the early stages of preparing for a presidential election," and Park has yet to sign his own letter.
Park, who has made his political career by speaking out in defense of the president, is expected to sign his impeachment letter in the next few weeks. The office said Wednesday that a doctor is unlikely to recommend a "strict regulatory stance" on Viagra, and Park's spokesman, Jung Youn-ja, would not be disclosing the medicine's safety.
Park's office has been accused of trying toutical companies that manufacture Viagra for commercial purposes, such as selling the drug through South Korean pharmacies.
Park has been in a legal relationship with his wife and daughter for a year, and they have been married since December last year. A spokesman for the state-run Blue House said "the Blue House does not believe that the president has any plans to interfere with the presidential election," and that the "resuddenly decided to suspend its activities in the country after the election."
The state-run Blue House said Wednesday that Park's office has not yet decided whether to suspend the sale of Viagra.
"As we know, Viagra has been linked to an increased risk of cardiovascular problems and a serious lack of awareness about the serious side effects of the drug. We will continue to monitor the situation closely," a spokesman said.
The state-run Blue House said it would not comment on the whether to remove the pills, saying only that the country's health ministry is monitoring the situation.
Park was asked to comment during a press briefing Thursday at the presidential office building in Daegu, North Korea. Park's office did not immediately respond to an email.
