Oscillococcinum® has been shown in clinical trials to reduce the severity and shorten the duration of flu symptoms.

Oscillococcinum (Oscillo®), one of the world’s most popular flu medicines, works rapidly, with 63 percent of patients showing “complete resolution” or “clear improvement” at 48 hours.‡1 In a double-blind, placebo-controlled clinical trial, the recovery rate within 48 hours of treatment was significantly greater in the group that received the active drug than in the placebo group. 2

Unlike other flu medicines, Oscillococcinum does not cause drowsiness or interact with other medications. Oscillococcinum is regulated as a drug by the FDA and can be purchased at pharmacies, natural food stores, and supermarkets.3

Make sure patients have Oscillococcinum on hand because it works best when taken early. Recommend Oscillococcinum at the first signs of flu. Help patients feel better before they feel worse.
