Tag: F 91 pill

Over 70-80% of patients receiving chemotherapy experience nausea and vomiting. The white, oval pill marked with 'F 91' is identified as Ondansetron 4 mg, a key medication used to prevent this distressing side effect.

According to the U.S. Food and Drug Administration (FDA), most solid oral medications are required to have an imprint code, yet sometimes similar markings can exist on different products. This is the case with the F-91 imprint, which can be found on at least two distinct medications, requiring careful attention to other physical characteristics for proper identification.
