PrimeZEN Black 6000 male enhancement capsules recall: Product contains undeclared tadalafil and sildenafil
Product contains undeclared tadalafil and sildenafil

The hazard: Undeclared allergen or ingredient
An ingredient subject to mandatory disclosure was left off the packaging, which is what the agency classes as misbranding.
What the notice says: Risk Statement: PrimeZen Black 6000 capsules containing sildenafil and tadalafil may interact with nitrates found in some prescription drugs (such as nitroglycerin) and may cause a significant drop in blood pressure that may be life threatening.
Why it matters: An ingredient that U.S. law requires to be declared is present but missing from the label. People who avoid that ingredient cannot make a safe choice from the packaging.
Symptoms and when to call a doctor
An undeclared allergen is a danger only to people allergic or intolerant to that ingredient. For everyone else the food is safe. Reactions range from an itchy mouth, hives, stomach cramps or vomiting through to anaphylaxis — swelling of the lips, tongue or throat, a tight chest, wheezing, a sudden drop in blood pressure or collapse. If anaphylaxis is suspected, use an epinephrine auto-injector straight away and call 911, even if the symptoms seem to settle, because a second wave can follow hours later.

What the company announced
FOR IMMEDIATE RELEASE – 2/13/2023 – Pomona, California, Volt Candy is voluntarily recalling one lot of PrimeZen Black 6000, 2000 mg capsule, to the consumer level. FDA analysis has found PrimeZen Black 6000 capsules to be tainted with sildenafil & tadalafil. Sildenafil and tadalafil are phosphodiesterase (PDE-5) inhibitors found in FDA-approved products for the treatment of male erectile dysfunction. The presence of sildenafil, tadalafil in PrimeZen Black 6000 capsules renders them unapproved drugs for which safety and efficacy have not been established and, therefore, subject to recall.
Risk Statement: PrimeZen Black 6000 capsules containing sildenafil and tadalafil may interact with nitrates found in some prescription drugs (such as nitroglycerin) and may cause a significant drop in blood pressure that may be life threatening. People with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. Among the adult male population who are most likely to use these products, adult males who use nitrates for cardiac conditions are most at risk from these products. Volt Candy has not received reports of state adverse events or injuries to date.

PrimeZEN — An ingredient subject to mandatory disclosure was left off the packaging, which is what the agency classes as misbranding.
- Read the official notice above for the exact ingredient involved, then check whether anyone in your home avoids it.
- Report any reaction to the FDA so it is recorded against this recall.

Refunds, and what else you can claim
The purchase price is the floor, not the ceiling. Where a recall caused you a real cost, say so.
- Claim the refund at the store first; it is the fastest route and needs the least paperwork.
- If you bought several packs over time, list them. Firms routinely settle for more than a single unit when a customer asks.
- Medical costs, lost earnings or a spoiled event are not handled at the service desk. Write to the company contact on this page instead, with dates and documents.
- Keep copies of everything you send. If a recall caused harm, that file is what any later claim rests on.
