The Health Ministry’s pharmaceutical crime unit seized counterfeit “erectile dysfunction” pills named SharkEssence, it was announced on Wednesday.

The pills were checked and each was found to contain 183 milligrams of sildenafil citrate, the active ingredient in the prescription drug Viagra, and 27 milligrams of tadalafil, the active ingredient in Cialis. The concentrations are higher than the maximum amounts; there are 100 milligrams in authentic Viagra pills and 20 milligrams in Cialis.

The ministry said use of these smuggled pills would be dangerous to public health. In addition, the ministry said it had no indication as to where the pills were made, how they were stored or how they were smuggled into the country.

The ministry warned the public to only purchase medications from licensed pharmacies and not via the Internet or inside Israel from unauthorized vendors.
