Your Client's Doctor Prescribed an OTC Drug. That Prescription Is Worth More Than the Medication.

James Wong — Founder & Pharmacist, LienScripts | April 23, 2025 | 7 min read

When a physician writes a prescription for a medication available over the counter, they are creating something an OTC purchase receipt never can: a dated clinical record documenting that self-directed care was insufficient for this patient's injury. Here is why that distinction matters in a demand package — and how LienScripts can cover OTC medications under the lien.

The difference between "I recommend you try Voltaren gel on your knee" and "I am prescribing diclofenac sodium gel 1% twice daily to the left knee" looks trivial on the surface. The product is identical. The dose is the same. A patient could walk into any pharmacy and buy the exact tube their doctor just wrote a prescription for.

But in a personal injury case, those two sentences produce completely different outcomes at settlement.

[!KEY] When a physician writes a prescription for a product also available OTC, they create documented clinical evidence that self-directed care was insufficient — defense cannot argue a medication is clinically insignificant when the treating physician wrote for it explicitly.

The Clinical Signal Embedded in a Prescription

When a physician writes a prescription for a product that happens to be commercially available without one, they are making a clinical statement: this patient's condition required pharmacist-managed, physician-directed care rather than self-directed over-the-counter use.

That statement matters. In pharmacy practice, the initiation of prescription therapy — even for a medication that has an OTC equivalent — reflects a clinical determination that OTC-level management was not sufficient for the presenting condition. The physician examined the patient, assessed the injury, and concluded that a documented, monitored prescription was the appropriate course of treatment.

Defense counsel's most common attack on medication costs is "the patient could have bought this at CVS." That argument fails when a physician explicitly disagreed with it in writing.

[!KEY] When a physician prescribes a product also available OTC, they have already made the defense's cheapest argument for them — and rejected it — because writing the prescription is a clinical statement that self-directed OTC management was insufficient, and that statement is in the medical record for the defense to explain away.

This is not a paperwork technicality. It is a documented clinical escalation. And it is exactly the kind of documentation that appears in a pharmacist's opinion regarding outline of services — which is precisely how LienScripts documents it in MERIT reports.

What Happens Without a Prescription

The physician's recommendation stays in the chart note. That note is part of the medical record, but it does not generate a pharmacy dispensing event.

The patient goes to a drugstore, finds the medication, and pays out of pocket. For a PI client who is likely uninsured or has coverage that won't touch accident-related medications, this means absorbing a cost they may genuinely not be able to afford. Many simply don't fill it.

If the patient does buy the OTC medication, there is no pharmacy record created. There is no dispensing date tied to a prescription. There is no entry in the medication history that connects the prescriber's name, the injury timeline, and the fill. There is nothing for a MERIT report to reference. There is nothing for the demand package beyond a receipt that could have come from anyone, at any time, for any reason.

What Happens With a Prescription

When a treating physician writes a prescription for a medication — including one that is commercially available OTC — and that prescription is submitted to LienScripts, the full lien infrastructure activates:

Coverage: OTC-equivalent medications dispensed on prescription are handled through LienScripts' non-formulary exception process. The treating physician documents the clinical rationale for prescription-level management, and LienScripts approves coverage — typically within two business days. The patient fills at zero upfront cost.

Documentation: A dated pharmacy dispensing record is created. It includes the medication name, the prescriber's name, the fill date, the quantity, and the days supply. That record is part of the patient's pharmacy history. It is contemporaneous with the injury. It is the kind of documentation that shows up in demand packages and cannot be dismissed as speculative.

[!TIP] Brief treating physicians at intake to write prescriptions for any medication they recommend — including those available OTC — so that every treatment decision is captured in the pharmacy record and can appear in the MERIT report.

The MERIT narrative: This is where the distinction becomes most meaningful at settlement. The pharmacist narrative framework built into LienScripts' MERIT reports explicitly uses over-the-counter versus prescription as a clinical severity marker. When a prescribed medication appears in the dispensing record — including one that could have been purchased OTC — the report can document that the physician determined ongoing prescription-level intervention was required rather than episodic or over-the-counter management. The absence of de-escalation to OTC alternatives is itself a clinical observation worth making.

That sentence is in the MERIT. It is there because prescription therapy means something. Defense cannot argue that a drug is clinically insignificant when the treating physician wrote for it and the dispensing record confirms the patient needed it filled and refilled across a course of treatment.

Which OTC Medications Come Up in PI Cases

Any medication available without a prescription can be written as a prescription by a licensed physician — the two statuses are not mutually exclusive. In personal injury treatment plans, the following OTC-available medications are frequently prescribed:

Topical analgesics: Diclofenac sodium gel 1% (Voltaren) is the most common. Physicians prescribe it for focal joint inflammation — a knee, a shoulder, a wrist — where targeted topical delivery is preferred over systemic NSAID exposure. Generic equivalents now crowd pharmacy shelves, but a physician's prescription for the specific product used by the patient establishes clinical intent.

NSAIDs at OTC doses: Ibuprofen 200–400 mg is OTC. Ibuprofen 800 mg three times daily is a prescription-level dosing regimen. When a physician prescribes the higher dose, the prescription documents that the patient's pain and inflammation required a clinical decision about therapeutic dose — not a guess at the checkout counter.

Naproxen sodium: The 220 mg OTC dose is for self-directed use. Prescription naproxen at 500 mg twice daily is a documented pain management regimen tied to an injury.

Sleep aids: Doxylamine and diphenhydramine are sold OTC for insomnia. When a physician prescribes a sleep aid for trauma-related sleep disruption — which is a documented consequence of musculoskeletal injury and psychological trauma — the prescription documents that the patient's sleep disruption was clinically meaningful, not just occasional discomfort.

Topical antihistamines and anti-itch preparations: Less common in PI, but prescribed for localized reactions, wound healing, and dermatological injury sequelae.

In each case, the underlying medication is the same. What changes is whether a physician looked at this patient, assessed this injury, and concluded that a prescription was warranted.

The Intake Conversation That Changes the Demand Package

Most attorneys do not brief their treating physicians on pharmacy lien documentation. Physicians who work with PI patients regularly are usually comfortable writing prescriptions — that is what they do. But many default to verbal recommendations for medications they consider minor, particularly ones that are available OTC.

That default is worth correcting at intake.

The practical guidance: when treating physicians recommend any medication to a PI patient — whether standard formulary or OTC-available — the recommendation should be written. A prescription creates a record. A verbal suggestion does not.

For medications already on LienScripts' standard formulary, the prescription routes directly through the program. For OTC-equivalent medications, a brief non-formulary exception request — initiated through LienScripts with the physician's clinical documentation — brings the medication under lien coverage within days.

The strongest demand packages combine all four layers: the physician's prescription, the pharmacy lien dispensing record, the MERIT pharmacist narrative, and (for non-standard medications) the physician's medical necessity letter. When all four are present, the defense argument that a medication was unnecessary, excessive, or could have been purchased for less becomes substantially harder to make.

[!KEY] Briefing treating physicians at intake to write prescriptions for every recommended medication — including OTC-available products — costs nothing and takes seconds, but it converts every treatment recommendation into a dated clinical record that can appear in the MERIT report and withstand defense scrutiny in the demand package.
