Health Canada warns public not to use Hua Fo

OTTAWA - Health Canada is warning consumers not to use Hua Fo tablets, an unapproved herbal product that claims to enhance sexual function. Health Canada analyzed samples of Hua Fo tablets and found that they contained sildenafil. Sildenafil is a drug approved as prescription only for male erectile dysfunction, sold under the brand name Viagra®. Use of sildenafil without medical supervision could cause severe adverse reactions.

Sildenafil should not be used by individuals who are taking any nitrate medication sold by perscription or over the counter. Nitrate medications are commonly used for angina. Concurrent use could result in the development of potentially life-threatening low blood pressure. In extremely rare instances, use of sildenafil could result in penile tissue damage and permanent loss of potency.

To date, there have been no adverse drug reactions reported to Health Canada, involving the use of Hua Fo. However, consumers who have used Hua Fo should contact their physicians.

Hua Fo is manufactured in China by Guizhou Ribulo Medical Industry Inc. and sold in Canada by Shenlong Company. The product is packaged in white plastic bottles containing red, round tablets. The bottles have a red label with the following directions for use: "300 mg. 50 tablets, Dosage: For adults only, take 2 tablets twice daily."

Health Canada is issuing this warning to advise consumers, health care professionals, and the provincial Ministries of Health of the safety issues related to the use of Hua Fo. Health Canada is also working with the importer of the product to ensure its removal from the market.
