You entered a 30-day supply and selected 75% used. 75% of 30 days is 22.5 days. Based on your selected counting method, the estimated timing date is AUG 25, 2026.
Suggested reminder: Check refill timing for this medication around AUG 25, 2026. Confirm with pharmacy or prescriber.
What to do next: Save the estimated date, compare it with the run-out date, and confirm the final timing with your pharmacy or insurance plan.

This calculator estimates dates using basic days-supply math. It does not decide whether a prescription can be legally, clinically, or operationally refilled. Final refill availability depends on your prescriber, pharmacy, insurance plan, medication type, state rules, and pharmacist judgment.

Emergency Prescription Refill Questions: What to Ask First

Travel delays, lost luggage, expired refills, or natural disasters can create urgent medication access problems. This page explains general questions to ask; it does not decide whether an emergency refill is available.

1. Pharmacist Emergency Dispensing and State Protocols

Some U.S. states allow pharmacists to provide limited emergency supplies of certain non-controlled maintenance medications when a prescriber cannot be reached. The supply length, medication types, documentation, and pharmacy requirements vary.

Some states have laws commonly called Kevin's Law or emergency-refill laws. Ask your pharmacist whether your state has a relevant process and whether your medication qualifies.

2. Insurance Claim Exceptions and Rejection Code 79

If medication is lost, damaged, stolen, or needed during travel before the usual timing point, an insurance claim may return a "Refill Too Soon" message. Ask the pharmacy or plan what documentation and exception process applies.

The pharmacy or plan may discuss claim-clarification or exception workflows, such as:

  • Lost, damaged, or stolen medication: The plan may ask for documentation and prescriber or pharmacy review.
  • Travel: The plan may have a travel exception process with limits and documentation requirements.
  • Declared emergencies: Plans and pharmacies may publish temporary procedures for affected areas.

3. Controlled Substance Restrictions

Controlled substances have separate requirements and may not follow the same emergency refill process as non-controlled maintenance medications.

Contact your prescriber and pharmacist directly for controlled-substance questions. Final availability may depend on a valid prescription, state and federal rules, PDMP review, pharmacy policy, and prescriber instructions.
