Introduction On 22nd Aug 2013, the Food and Drug Administration (FDA) is

advising consumers not to purchase or use Ortiga, which is an unapproved product.

Ortiga is sold on multiple websites, including www.ebay.com, and in some retail stores. 

Ortiga is manufactured in Mexico and labeled primarily in Spanish.

Ortiga contains the prescription drug ingredient, diclofenac and was confirmed by FDA laboratory analysis.

Diclofenac is a non-steroidal anti-inflammatory drug (commonly referred to as NSAIDs) which may increase the risks of heart attack, stroke, gastrointestinal bleeding, ulceration, and fatal perforation of the stomach and intestines. 

Diclofenac may also interact with other medications and significantly increase the risk of adverse events, particularly when consumers use multiple NSAID-containing products.

Conclusion Consumers should stop using Ortiga immediately and dispose of it.  Consumers should consult a health care professional as soon as

possible if they have experienced any negative side effects, such as unusually dark stools or urine, stomach pain, increased bruising, or other signs of bleeding.

The purpose of this notification is to inform the public of a growing trend of dietary supplements or conventional foods containing hidden drugs and chemicals. 

These products are typically promoted to unsuspecting customers for sexual enhancement, weight loss, and body building, or for other medical uses and are often represented as being “all natural.” 

FDA is unable to identify and test all such products that may have potentially harmful hidden ingredients. 

Consumers should exercise caution before purchasing any product in the above categories.
