10 Day Forecast: FDA found sildenafil and acetaminophen

On October 15, 2026, the FDA advised consumers not to buy or use 10 Day Forecast, a product promoted for sexual enhancement. Laboratory analysis confirmed sildenafil and acetaminophen that were not listed on its label. The finding concerns this named product; the notice does not give tested amounts or prove every package is identical. [1]

What the FDA found

The FDA says 10 Day Forecast was promoted and sold for sexual enhancement on various websites, including eBay, and possibly in some retail stores. Its laboratory analysis confirmed sildenafil and acetaminophen, neither listed on the product label. The public notice does not identify a tested lot or state how much of either drug the sample contained. [1]

Why undeclared sildenafil is a serious concern

Sildenafil is the active ingredient in prescription Viagra. The FDA warns that it can interact with nitrates in some medicines, including nitroglycerin, and drive blood pressure dangerously low. The official prescribing information also says sildenafil must not be used with nitrate medicines. A consumer cannot safely judge this risk from a supplement label that does not disclose the ingredient or amount. [1][2]

The second hidden drug matters too

Acetaminophen is a common pain and fever medicine, but taking too much can cause severe liver damage, liver failure, or death. The FDA warns that signs may not appear for several days. Because its notice does not state the amount found in 10 Day Forecast, it does not let buyers calculate an exposure or assume a dose is safe. [1][3]

If you bought or used it

Follow the FDA's advice: do not buy or use 10 Day Forecast. If you have taken it, contact a healthcare professional or Poison Help at 1-800-222-1222 promptly and show them the package and a list of medicines you take. Do not wait for symptoms if you think you may have taken too much acetaminophen; the FDA says liver injury can be delayed. For chest pain, fainting, severe symptoms, or a possible emergency, call 911. Suspected reactions can also be reported to FDA MedWatch. [1][3]

What this warning does not establish

The FDA notice does not publish a dose, identify every seller, or say what any seller knew. It does not prove that every package has identical contents or that every sexual-enhancement supplement contains hidden drugs. This is a product-specific warning for the United States, not a statement about availability or regulatory status in every country. [1]

What drugs did the FDA find in 10 Day Forecast?

The FDA's laboratory analysis confirmed sildenafil and acetaminophen that were not listed on the label. The public notice does not state the amounts detected. [1]

Does this warning apply to every sexual-enhancement product?

No. The FDA warning names 10 Day Forecast and reports test results for that product. It is not evidence that every product in this category has the same ingredients. [1]

Our recommendation

We do not recommend 10 Day Forecast. The FDA confirmed two undeclared drug ingredients in the named product and directly advises consumers not to buy or use it. [1]
