Health Canada is advising consumers not to use Dai Dai Hua Jiao Nang, Darling Capsules, Dali Capsules, Spanish Fly Capsules, an unnamed product, due to concerns about possible side-effects.
Medsafe, the New Zealand health regulatory authority, advised the public not to use the products Darling Capsules, Dali Capsules, Spanish Fly Capsules, and an unnamed product, because they were found to contain sildenafil. Medsafe also advised the public not to use the product Dai Dai Hua Jiao Nang because it was found to contain sibutramine.
Sildenafil and sibutramine are prescription medications indicated for treatment of erectile dysfunction and obesity, respectively. They should only be used under the supervision of a health care professional.
Side effects associated with sildenafil citrate include headache, flushing, gastrointestinal disorders, penile tissue damage, visual disturbances, and inflammation of the mucous membrane of the nose.
Products containing sildenafil citrate should not be used by anyone taking a nitrate medication, as the combination could lead to potentially life-threatening low blood pressure.
Sibutramine is the active ingredient in a prescription drug marketed in Canada for the treatment of obesity. It should only be used under the supervision of a health care professional. Its side effects may include increased heart rate and blood pressure, and headaches.
