Class I · High risk Terminated Initiated Jan 25, 2019 (8 years ago)

the silver bullet 10x Capsules

Class I — High risk. Reasonable probability of serious harm or death.

Why it was recalled

Marketed without an Approved NDA/ANDA; FDA analysis found product to be tainted with undeclared sildenafil and tadalafil

Cause type: Chemical / undeclared

A chemical that should not be there - benzene, methanol, lead - or an undeclared prescription drug hidden in a supplement. The label gives no warning: you may be taking a toxic solvent, a heavy metal, or a drug such as sildenafil that interacts with your other medicines. All chemical / undeclared recalls.

FDA recall number
D-0500-2019 · FDA notice

Treat this as urgent. Class I means FDA judged there is a reasonable probability of serious harm. Find the lot number on your package; if it matches the recalled lots, do not take another dose before you have spoken to your pharmacist or prescriber - today, not next week. This recall is now terminated, which means the firm has finished removing the affected product; anything on pharmacy shelves today should be unaffected.
