This oral syringe is not like the others
The oral syringes that come with risperidone oral solutions are uniquely labeled and may cause confusion. Risperidone is a medicine used to treat certain mood disorders. Unlike other oral syringes, risperidone oral syringes have a barrel (the part that holds the medicine) that does not have any lines or numbers (markings). Instead, the markings appear on the plunger ( Figure 1). To measure a dose, the plunger must be pulled back until the dose marking aligns with the flange (winged end) of the barrel. Even though these syringes are different than other oral syringes, the instructions do not provide detailed, clearly illustrated information on how to read the markings when measuring a dose. We recently learned about a man who may have taken too much risperidone due to confusion with the dose markings.

A woman with colon cancer recently received a full dose of fluorouracil at home over 4 days instead of 7 days. Fluorouracil is a drug used to treat cancer by causing fast-growing cancer cells to die. The medicine was given directly into a vein (intravenously) through a portable infusion pump that the woman wore while she was at home. For an unknown reason, the full amount ran in too quickly, leading to an overdose of the medicine. The effects of an overdose are serious and can be fatal. The effects from the medicine infusing too quickly include nausea, vomiting, diarrhea, mouth ulcers, stomach bleeding, and a weakened immune system (making it harder to fight off diseases).
Learn MoreOverdoses related to “pill dumping” into a spare medication vial
Pharmacists from the Maryland Poison Center recently published several cases of what they refer to as “pill dumping.” An article in the American Journal of Health-System Pharmacy 1 describes the term “pill dumping” for when patients use a spare medication vial to hold multiple medications taken from different labeled prescription vials.

Good catch! A mother picking up a prescription for her son was supposed to receive methylphenidate for attention deficit hyperactivity disorder (ADHD). Instead she was given a cardiac drug intended for another patient. The mother noticed the error because the pharmacist mentioned the medicine was for “chest pains.” It turned out that the two patients had the same name. Before leaving the pharmacy with your prescription, always make sure to verify your name and another identifier, such as your date of birth or address. It’s also important for pharmacists to provide drug information when you pick up your prescriptions. After all, that’s how this error was prevented.
