Denver Prescription Dosage Error Attorneys

When you pick up a prescription, you trust that the medication is correct, the dosage is accurate, and the instructions are safe to follow. Most of the time, that trust is well placed. But when a pharmacist or pharmacy makes a mistake, the consequences can be devastating. A medication error can lead to serious illness, hospitalization, permanent injury, or even death.

Pharmacy errors happen more often than many people realize. Patients may receive the wrong medication, the wrong dosage, incorrect instructions, or a drug that dangerously interacts with another prescription. These mistakes can affect anyone, but they can be especially dangerous for children, older adults, and people with complex medical conditions.

If you or a loved one was harmed by a pharmacy error in Denver or anywhere in Colorado, you may have legal rights under Colorado law. Pharmacists and pharmacies have a duty to dispense medications safely and accurately. When they fail to meet that responsibility, they can be held accountable for the harm they cause. At Frenkel & Frenkel, our Denver pharmacy error lawyers understand the medical and legal issues involved in these cases. We know how to investigate medication mistakes, preserve critical evidence, and pursue compensation from pharmacies, healthcare providers, and their insurers.

We offer free consultations and handle pharmacy malpractice cases on a contingency fee basis. You pay nothing unless we recover compensation for you.

What Can a Denver Prescription Error Lawyer Do for You?

If a Denver pharmacist filled your prescription with the wrong drug, the wrong dose, or missed a dangerous drug interaction, you may be able to recover money for medical bills, lost income, pain and suffering, and other losses. A Denver prescription dosage error lawyer can investigate what happened, gather records, work with medical experts, and build a claim against the pharmacist and the pharmacy. Colorado law also requires special steps, including a Certificate of Review from a qualified expert filed within 60 days of serving the complaint. Acting fast helps protect evidence and deadlines.

HOW COLORADO LAW TREATS PHARMACY NEGLIGENCE

Colorado treats pharmacist error claims as professional negligence, governed under the Colorado Health Care Availability Act (HCAA) and the standards set by the Colorado State Board of Pharmacy. Colorado law adds steps that do not apply in ordinary negligence cases.

THE CERTIFICATE OF REVIEW REQUIREMENT

The key procedural step is the Certificate of Review. Under C.R.S. sec. 13-20-602, within 60 days of serving the complaint, your attorney must file a Certificate of Review confirming that a qualified expert reviewed the case and found it has substantial justification. A separate certificate is required for each defendant. Failure to file on time can result in dismissal of your claim.

What Pharmacists Are Required to Do?

DRUG UTILIZATION REVIEW

Colorado pharmacy rules are detailed and enforced by the Colorado State Board of Pharmacy (dpo.colorado.gov/Pharmacy). Before filling a prescription, pharmacists must conduct a prospective drug utilization review — checking for allergies, drug interactions, duplicate drugs, and whether the dose is safe. If the pharmacist skips that review or rushes through it, that may be a breach of the standard of care.

PATIENT COUNSELING

Colorado pharmacists must also counsel patients who receive new prescriptions. That counseling should explain the drug name, the right dose, how to take it, side effects, drug interactions, storage, and what to do if a dose is missed.

Who Can Be Held Liable for a Prescription Error

Often, more than one party may be at fault. The pharmacist who filled the prescription may be liable for their own negligence. The pharmacy that employed them may also be liable under respondeat superior.

Large pharmacy chains like CVS, Walgreens, Walmart, Kroger, and others can also face direct corporate liability when their own policies helped cause the error. If a chain sets impossible volume goals, understaffs stores, or fails to use safe systems, those choices can help cause injury. If the prescribing doctor made the original mistake, the doctor may share liability too. Colorado uses a modified comparative negligence system (C.R.S. sec. 13-21-111): a jury can divide fault among several defendants, but if you are found 50% or more at fault, you may be barred from recovering damages.

What is the deadline to file a prescription error claim?

Colorado law usually gives you two years from the date of the error or from when you discovered your injury to file a pharmacy malpractice claim. There is also a 10-year statute of repose. That means no claim can be filed more than 10 years after the negligent act, no matter when you learned about it. You must also give each defendant written notice at least 60 days before filing suit. With the 120-day expert report rule, the timeline is short. Call a lawyer quickly.

How do you prove a pharmacist was negligent?

To prove pharmacy negligence in Colorado, you need proof that the pharmacist’s conduct fell below the standard of care and caused your injury. Key evidence can include the original prescription, dispensing records, the medication label, the patient record showing your allergy and drug history, records showing whether a drug review was done, and your medical records. A qualified expert is also required under Colorado’s Certificate of Review requirement (C.R.S. sec. 13-20-602). The expert must be a licensed pharmacist or a doctor with pharmacology knowledge.

Quick Answer

Can You Sue a Pharmacy for Giving You the Wrong Prescription?

Yes. In Colorado, pharmacists and pharmacies are treated as healthcare providers under Chapter 74 of the Colorado Civil Practice and Remedies Code. That means they can be sued for medical negligence when their mistakes cause harm. To bring a valid claim, you usually must show duty, a breach of the standard of care, causation, and real damages. Depending on where the error began, you may have claims against the pharmacist, the pharmacy, and sometimes the doctor.

Should I talk to the pharmacy’s insurance company on my own?

We suggest that you speak with a lawyer before giving any recorded statement or signing anything from a pharmacy or its insurer. Insurance adjusters are trained to protect their company’s money. Early statements, even honest ones, can be used to limit or deny your claim. A lawyer can handle those talks for you.

Common Types of Prescription Dosage Errors

Wrong Medication

A patient may get a different drug than the one the doctor ordered. That can mean an allergic reaction, a bad interaction, or no treatment at all. This often happens with drugs that sound alike, such as hydroxyzine and hydralazine, or with similar packaging.

Wrong Dose

A dose that is too high or too low can cause serious harm. An overdose may lead to toxicity, organ damage, or death. An underdose can let a condition get worse or harder to treat. These errors are especially dangerous with drugs that have a narrow safe range, including warfarin, anti-seizure drugs, heart drugs, and lithium.

Drug Interactions

Colorado law requires a drug review before the prescription is filled. That review should check for dangerous interactions with the patient’s current medicines. If the review is skipped or done carelessly, the patient may get a drug that reacts badly with another medicine. That can cause heart rhythm problems, seizures, severe bleeding, or other life-threatening harm.

Labeling Errors

Wrong label information, like the wrong drug name, wrong directions, the wrong patient name, or missing warnings, can cause a patient to use medicine the wrong way for weeks or months. Because patients rely on the label every day, labeling errors can cause long-lasting harm.

Nursing Home Abuse Statistics

About 1.5 million Americans are harmed by prescription and medication errors every year. An estimated 7,000 to 9,000 deaths are linked to medication mistakes each year in the United States.
Colorado recorded 127 adverse action reports related to pharmacy practice in a recent review, the highest number in the nation. That reflects the state’s large population, high prescription volume, and many major retail chains.
Research suggests that up to 5 percent of all filled prescriptions may contain some type of error. Look-alike or sound-alike drug names account for about 25 percent of reported medication mistakes.
Older adults age 75 and older are 38 percent more likely to have a medication error. Children face an adverse drug event risk three times higher than adults. That makes these mistakes especially dangerous for vulnerable people in Denver.

Frequently Asked Questions

Frenkel & Frenkel offers a free initial consultation. We handle prescription error cases on a contingency fee basis, which means you pay nothing unless we recover money for you. There are no upfront fees and no out-of-pocket costs to get started.

Depending on your facts, you may be able to recover past and future medical expenses, lost wages, reduced earning ability, pain and suffering, physical impairment, and emotional distress. In cases involving gross negligence or willful misconduct, punitive damages may also be available. Economic damages are not capped under Colorado law, but non-economic damages like pain and suffering are limited under the Colorado Medical Liability Act.

Many people are unsure at first. A sudden change in how you feel after picking up a prescription, unexpected side effects, a new medical problem soon after a medicine change, or a doctor saying the medicine was wrong are all reasons to look deeper. Our attorneys can review your records, work with medical experts, and help you decide if you have a claim. The consultation is free and there is no obligation.

No. Large chain pharmacies can face claims when their pharmacists make mistakes that harm patients. If the chain’s staffing policies, volume pressure, or poor training helped cause the error, the company may be liable along with the pharmacist. It helps to have a lawyer who understands both pharmacist negligence and corporate pharmacy liability.

Prescription errors sometimes start with the doctor, such as when the doctor orders a drug that interacts with another medicine or calculates the wrong dose. In those cases, the doctor may share liability. Colorado uses proportionate responsibility rules, so fault can be divided among several parties. Your lawyer will review the full chain of events.

Yes. You can file a complaint with the Colorado State Board of Pharmacy through the Division of Professions and Occupations (dpo.colorado.gov/Pharmacy, 303-894-7800). That process is separate from a civil lawsuit and does not recover money for you.

Keep the medication bottle and label, the original prescription if you have it, pharmacy receipts, and records of all medical treatment you received because of the error. Take photos of the label and the medication if you can. Do not return the medicine to the pharmacy or throw it away. Contact a lawyer as soon as possible so evidence can be preserved before records are changed or overwritten.

The attorneys at Frenkel & Frenkel have spent decades representing injured people across Colorado.
