The Tenfold Suspension Error and the Request to Stay Quiet
A three-year-old weighing 15 kg is prescribed amoxicillin 400 mg/5 mL, 7.5 mL by mouth twice daily for 10 days. The technician enters 250 mg/5 mL, 7.5 mL twice daily, and the label prints accordingly. The pharmacist verifies between two vaccine appointments, glancing only at the drug name and the patient name. Two days later the parent returns: the child's ear pain persists and the bottle is nearly gone. The parent speaks limited English; the label and the brief instructions at pickup were in English only, and the family has been dosing with a kitchen teaspoon. The pharmacist who verified the prescription is off today; a colleague suggests handing over a replacement bottle and not writing anything up, since nothing serious happened and the error report would only create paperwork.
1. What are the clinical and professional consequences of the error, and what must the pharmacy do now?

The dose delivered was wrong by a large margin. The prescription called for 400 mg/5 mL x 7.5 mL = 600 mg twice daily, or 1,200 mg/day (80 mg/kg/day, an appropriate high-dose regimen for acute otitis media). What was dispensed delivered 250 mg/5 mL x 7.5 mL = 375 mg twice daily, or 750 mg/day - roughly 62 percent of the intended dose, at 50 mg/kg/day. A subtherapeutic beta-lactam course over 10 days invites treatment failure, persistent effusion, and eventually a resistant organism.
Immediate actions:
- Assess the child now: current symptoms, fever, hearing, any signs of mastoiditis or worsening. Direct the family to the prescriber today; this is not a wait-and-see situation.
- Contact the prescriber, disclose what was dispensed, and obtain a corrected prescription.
- Provide the correct product at no charge and replace the dosing device with an oral syringe marked in mL.
- Disclose to the parent in plain language, with a qualified interpreter: what happened, what it means, what to watch for, and what the pharmacy is doing.
- Write the incident report the same day, factually, and check whether any other prescriptions were entered or verified in that window.
- Start a root-cause review: look-alike concentrations, verification interrupted by vaccines, no barcode scan at fill, no second check on the concentration.
2. Evaluate the labeling and counseling that occurred. What should a compliant label and counseling encounter have included?

The label was technically legible and clinically inadequate.
A compliant label should show: pharmacy name, address, and phone; prescription number; date filled; patient name; prescriber name; drug name and concentration (amoxicillin 400 mg/5 mL, not merely amoxicillin); quantity in mL; directions in mL with frequency and duration; beyond-use date; number of refills; and auxiliary warnings - shake well, refrigerate, discard remaining suspension after 10 days.
Counseling failures were separate and more serious:
- Counseling must be offered by the pharmacist at dispensing, not at drop-off five hours earlier, and it must be in a language the patient understands. A signature at drop-off does not waive it retroactively.
- The English-only label for a family with limited English proficiency is a patient-safety defect. Use a qualified interpreter or language line, translated directions where available, and teach-back. Do not recruit a bystander or a Spanish-speaking clerk to interpret clinical content.
- The dosing device matters: a kitchen teaspoon is 3 to 6 mL of error potential. Dispense an oral syringe and demonstrate the 7.5 mL mark.
- Confirm understanding by having the parent repeat the dose, frequency, and duration back, and state what to do if a dose is missed or the child vomits.
The pharmacist's glance that skipped the concentration is the proximate cause, but the absence of a meaningful counseling step removed the last chance to catch it.
3. Respond to the colleague's suggestion to swap the bottle and skip the report. What are the pharmacist's obligations and the risks of staying quiet?
Read the worked answer
Decline the suggestion, and be direct about why.
The patient and family are entitled to know that a medication error occurred and what it means for the child's care. A silent bottle swap conceals the fact that the child received two days of an inadequate dose and may need re-evaluation and a different antibiotic. It also leaves the parent dosing with a kitchen spoon and reading an English-only label, which reproduces the same failure next month.
On the record side: creating an accurate, contemporaneous incident report is a professional obligation, and falsifying, suppressing, or backdating a pharmacy record is independently a ground for discipline regardless of the underlying error. The report is not an admission of liability; it is a safety document, and without it the store cannot fix the interrupted-verification workflow, the look-alike concentrations, or the missing scan.
Whether Colorado imposes an affirmative duty on one pharmacist to report a colleague to the Division, the obligation not to conceal does exist: the pharmacist should not participate in the cover-up, should ensure the report is written, and should escalate internally to the pharmacist in charge. If the colleague persists in suppressing the record, escalation to the owner and to the Division is appropriate. The professional risk of candor is small; the professional risk of a concealed pediatric error is not. Finally, notify the prescriber before the family arrives, so the prescriber is not blindsided.
