Overview

A medication error case in Pennsylvania is usually a medical malpractice claim. To move forward in court, you almost always need a Certificate of Merit (COM) —a short filing that confirms a qualified expert supports your case.

Without a timely and proper COM, Pennsylvania courts can dismiss your lawsuit by entering a judgment of non pros , even if the error seems obvious.

Do You Qualify?

  • Medication error by a PA licensed professional: Doctor, nurse, hospital, pharmacist, or pharmacy involved in prescribing, dispensing, or administering medication.
  • Injury and losses: You suffered harm (e.g., hospitalization, worsened condition, additional treatment, lost wages, or death).
  • Filed on time: Generally a 2-year statute of limitations from when you knew or should have known about the injury; special rules for minors and estates.
  • Expert support available: A qualified professional (e.g., pharmacist or physician with appropriate specialty) can say there’s a reasonable probability the care fell below standards and caused harm.
  • Right defendants: Individuals and entities responsible (e.g., prescriber, hospital, pharmacy). Separate COMs may be needed for each.
  • Not a product defect claim: If the issue is a defective drug or device, that’s product liability and may not require a COM.

How PA Law Applies

Pennsylvania Rule of Civil Procedure 1042.3 requires a Certificate of Merit in any professional negligence case, including medication errors against health care providers and pharmacists.

Deadline: File the COM within 60 days after the complaint . You may ask the court for one extension (up to 60 days) if requested before the deadline and for good cause.

What the COM says: One of the following: (1) A qualified expert provided a written statement that there’s a reasonable probability the care fell outside acceptable standards and caused harm; (2) The defendant is sued for vicarious liability only ; (3) No expert is needed (rare, e.g., plainly wrong drug to the wrong patient).

One COM per defendant: File a separate COM for each professional or entity unless the entity is named solely on a vicarious basis.

Expert qualifications: The expert must meet Pennsylvania’s MCARE Act standards (40 P.S. § 1303.512), typically same or similar specialty and active in practice or teaching.

Missing the COM: The defense can issue a 30-day Notice of Intent (Pa.R.C.P. 1042.6). If you still do not file, the prothonotary can enter a judgment of non pros (Rule 1042.7), which can end your case.

Government defendants: If a public hospital or government provider is involved, special notice-of-claim rules and damage limits may apply.

Step-by-Step: What to Do

  • Save medication bottles, labels, discharge instructions, and pharmacy receipts.
  • Request your complete medical and pharmacy records early.
  • Write a timeline (who prescribed, what was dispensed, when symptoms appeared).
  • They will identify all proper defendants (prescriber, nurse, hospital, pharmacist, pharmacy).
  • They will obtain a pre-suit expert review to support the COM under Rule 1042.3 and MCARE § 512.
  • If the deadline is close, they may first file a writ of summons to toll the statute, then file the complaint and COM.
  • File the complaint, then the COM within 60 days (or timely request one 60-day extension for good cause).
  • File a separate COM for each defendant , noting if any are vicarious-only.
  • If you receive a 30-day Notice of Intent to take a non pros , cure immediately by filing the missing COM(s) or seeking court relief.
  1. Act fast and preserve evidence: Save medication bottles, labels, discharge instructions, and pharmacy receipts.
  2. Request your complete medical and pharmacy records early.
  3. Write a timeline (who prescribed, what was dispensed, when symptoms appeared).
  4. Hire a PA medical malpractice lawyer: They will identify all proper defendants (prescriber, nurse, hospital, pharmacist, pharmacy).
  5. They will obtain a pre-suit expert review to support the COM under Rule 1042.3 and MCARE § 512.
  6. If the deadline is close, they may first file a writ of summons to toll the statute, then file the complaint and COM.
  7. File correctly and track deadlines: File the complaint, then the COM within 60 days (or timely request one 60-day extension for good cause).
  8. File a separate COM for each defendant , noting if any are vicarious-only.
  9. If you receive a 30-day Notice of Intent to take a non pros , cure immediately by filing the missing COM(s) or seeking court relief.

Common Mistakes to Avoid

  • Missing the 60-day COM deadline: Leads to non pros and potential loss of the claim.
  • Using an unqualified expert: Your COM may be attacked if the expert doesn’t meet MCARE § 512 standards or specialty requirements.
  • Filing one COM for multiple defendants: Pennsylvania expects one COM per professional defendant unless vicarious-only.
  • Waiting for records too long: Delays can jeopardize SOL and COM timing.
  • Mislabeling claims: Corporate negligence claims against hospitals or pharmacies usually need their own direct-liability COM , not just vicarious.
  • Assuming “obvious error” means no expert: Courts rarely waive experts; use the “no expert needed” option cautiously.
  • Ignoring government notice rules: Claims against public entities may require early written notice and have damages caps.

What You Should Do Next

Consult a Pennsylvania medical malpractice attorney immediately. Bring your medication containers, pharmacy printouts, and a written timeline. Ask the lawyer about expert review, the COM strategy for each defendant, and deadlines for the complaint and COM.

Time is critical. A prompt expert review and correctly filed Certificates of Merit can preserve and strengthen your PA medication error case.
