biQ-FEL Recall: FDA Finds Undeclared Viagra and Cialis Ingredients

The FDA says recalled biQ-FEL supplement bottles contained undeclared sildenafil and tadalafil. Learn which lots are affected and what consumers should do.

Consumers who purchased a liquid dietary supplement online are being urged to check their bottles after federal regulators announced a nationwide recall involving undeclared prescription drug ingredients.

A&P Creations LLC is recalling certain lots of biQ-FEL, a 500-milliliter liquid dietary supplement, after laboratory testing by the U.S. Food and Drug Administration detected sildenafil and tadalafil that were not listed on the product's label. Sildenafil is the active ingredient in Viagra, while tadalafil is the active ingredient in Cialis.

The company announced the recall on Sept. 14, 2026, and the FDA published the recall notice on Sept. 15. According to the FDA, the product was distributed to consumers in the United States through online marketplaces and websites, including Amazon, Walmart.com and naturefuel.us.

Why the recalled supplement may pose a health risk

The concern is not simply that the product contained ingredients commonly associated with prescription erectile dysfunction medications. The FDA says the substances were not declared on the product label, meaning consumers could have taken them without knowing they were present.

Sildenafil and tadalafil belong to a class of medicines known as phosphodiesterase-5, or PDE5, inhibitors. These medications increase blood flow by affecting an enzyme involved in the body's response to sexual stimulation. Sildenafil is used to treat erectile dysfunction and pulmonary arterial hypertension, while tadalafil is used for erectile dysfunction, pulmonary arterial hypertension and symptoms associated with an enlarged prostate.

Both medicines are prescription drugs, and their use can depend on a person's other medications and medical conditions.

One particularly important concern involves nitrate medications. The FDA warns that sildenafil and tadalafil can interact with nitrates, including medications such as nitroglycerin, potentially causing blood pressure to fall to dangerously low levels. People with certain cardiovascular conditions may be prescribed nitrate medications, making an undisclosed dose of either drug especially concerning.

Mayo Clinic likewise advises that erectile dysfunction medicines such as sildenafil and tadalafil should not be used with nitrate medicines because of the potential for a dangerous drop in blood pressure.

Which biQ-FEL products are included in the recall?

The FDA recall applies to specific lots of biQ-FEL 500 mL liquid supplement.

The affected products are:

• Lot: biQ-f001-06-25
  Expiration: 05/06/27
  UPC/barcode identifier: biQ-FEL
• Lot: biQ-003-01-26
  Expiration: 01/01/28
  UPC/barcode: 7709799120663

The product was packaged in 500-milliliter bottles carrying the biQ-FEL name. The labeling includes Spanish-language wording, including the phrase "Sabor artificial Hierbabuena."

Consumers who purchased the product online should compare the lot and expiration information on their bottle with the details in the FDA recall notice.

What consumers should do with recalled bottles

The FDA and the company advise consumers who have one of the recalled products to stop using it immediately and destroy the product.

Anyone who believes they experienced a health problem after taking the supplement should contact a physician or other healthcare professional. Consumers and healthcare providers can also report suspected adverse reactions or product-quality concerns through the FDA's MedWatch reporting program.

Consumers should not assume that a supplement is harmless simply because it is marketed as a dietary or natural product. The FDA previously warned consumers about biQ-FEL after laboratory testing found the same two undeclared drug ingredients. The agency has also cautioned that some products marketed for sexual enhancement can contain hidden prescription drugs or other undeclared substances.

What are the risks of sildenafil and tadalafil?

When prescribed and used appropriately, sildenafil and tadalafil are established medical treatments. However, they are not appropriate for everyone.

Mayo Clinic notes that erectile dysfunction medicines can interact with several medications and may be unsuitable for people with certain medical conditions. Potential side effects can include headache, flushing, stomach discomfort, dizziness and changes in vision. More serious reactions can include sudden hearing or vision problems and prolonged or painful erections requiring immediate medical attention.

Tadalafil also carries specific warnings involving prolonged erections, sudden vision loss and sudden hearing changes. Patients are advised to tell healthcare professionals about their medications and medical history before using the drug.

The issue with the recalled supplement is therefore not necessarily that sildenafil or tadalafil are inherently unsafe. Rather, the concern is that consumers may have unknowingly consumed prescription drug ingredients without knowing the amount present or considering whether those ingredients were appropriate given their medications and health conditions.

Company stops distribution

According to the FDA, A&P Creations LLC distributed biQ-FEL as a finished product but did not manufacture or formulate it.

The company has stopped distributing the affected product and said it is notifying customers through direct electronic communications and procedures used by the online marketplaces involved in distribution. As of Sept. 14, the company had not received reports of adverse events associated with the recall.

Consumers with questions about the recall can contact the company at ecommerce@naturefuel.us, Monday through Friday from 9 a.m. to 4 p.m. Eastern Time.

A broader warning about sexual enhancement supplements

The biQ-FEL recall illustrates why consumers should be cautious when purchasing products marketed as dietary supplements for sexual enhancement.

The FDA says it cannot test every product marketed as a dietary supplement for potentially harmful hidden ingredients. The agency has previously warned consumers about products that appear to be supplements but contain undeclared prescription drugs or other chemicals.

Consumers considering an erectile dysfunction product should discuss their options with a qualified healthcare professional, particularly if they take medication for heart disease, blood pressure or other chronic conditions.
