THE Food and Drug Administration (FDA) has issued a warning against the consumption of a herbal dietary supplement marketed for libido enhancement after tests revealed the presence of sildenafil citrate, a prescription drug used to treat erectile dysfunction in men.
Sildenafil citrate, commonly known by the brand name Viagra, is prohibited in food supplements.
FDA Advisory No. 2025-0365, signed by FDA Director General Dr. Samuel Zacate, states that laboratory analyses of Drivemax Plus Brand herbal dietary supplement capsules, specifically those with the following lot numbers and expiration dates, have been found to contain sildenafil citrate: 24581626 (April 5, 2026), 23521625 (August 8, 2025), 23551625 (November 8, 2025), and 24561626 (January 22, 2026).
The FDA has instructed all law enforcement agencies and local government units to ensure that these products are not sold in their respective areas. Consumers who have taken the adulterated Drivemax capsules are advised to consult a doctor immediately if they experience any of the following side effects: headache, diarrhea, dizziness or lightheadedness, urinary tract infection, priapism (prolonged erection), indigestion, nasal congestion, rashes, and changes in vision or sudden vision loss.
According to its website, Drivemax is a dietary supplement for men and women designed to enhance declining sexual performance through natural ingredients such as horny goat weed, ginseng, Tribulus terrestris, tongkat ali, and Gingko biloba.
