The products contain undeclared ingredients, which are analogues of sildenafil and vardenafil, western medicines used for treating erectile dysfunction.

Distributors of five of the products have been instructed to recall and surrender them to the department.

Side effects associated with both sildenafil citrate and vardenafil hydrochloride include headache, flushing, gastrointestinal disorders, penile tissue damage, visual disturbances, and inflammation of the mucous membrane of the nose. Sildenafil and vardenafil can interact with nitrates found in some prescription drugs, like nitroglycerin, and can lower blood pressure to dangerous levels.

People who have the products should stop using them immediately, and seek medical attention if they feel unwell.

Sildenafil and vardenafil are prescription medications indicated for treatment of erectile dysfunction. They should only be used under the supervision of a health care professional.

Saudi Food and Drug Authority advise that the above products are not registered and marketed in Saudi Arabia. Whereas, availability of those products in Saudi Arabia could be through either travelers getting those products for personally or online purchasing.
