51.9K Prices: Headache, Allergy & Heartburn
How do listed and package-standardized prices for common over-the-counter pain, allergy, and heartburn products differ across U.S. ZIP markets and days?
This fixed research snapshot contains 51,861 unaggregated, quality-filtered price observations across 4 medicine categories, 12 U.S. ZIP markets, and 29 consecutive dates from July 21 through August 18, 2026. The analysis-ready CSV preserves product titles, dates, geography, listed package quantities and prices, plus a source-neutral 100-unit comparable-price field when quantity is resolved.
What “quality-filtered” means here: the rows are unaggregated product-level observations after category, safety, and exact-duplicate filtering. The file includes derived comparison fields and is a prepared research snapshot rather than an aggregate index.
Dataset at a glance
What one row represents
One row is one quality-filtered product-title, ZIP-market, date, package-quantity, and listed-price observation in one medicine category. It is not a sale, prescription, treatment, order, demand, inventory, market-share, or patient record. Multiple distinct offers can share a title, ZIP, and date; exact duplicate public rows have been removed.
Comparable-price method
price_amount preserves the listed price. Where a compatible package quantity is resolved, normalized_price_amount scales that price to 100 units, recorded in normalized_quantity_value and normalized_quantity_unit.
Compare normalized values within the same series_id. Rows whose quantity is unresolved or incompatible retain the listed price and leave normalized_price_amount blank. Price observations do not indicate clinical equivalence, dose, effectiveness, safety, or recommended use.

Project ideas
- Compare within-category 100-unit price distributions across the 12 ZIP markets.
- Measure how daily medians and dispersion change across the 29-day window.
- Study whether listed-package price gaps narrow or widen after quantity normalization.
- Model which product-title and package formats are most likely to have unresolved comparable prices.
Quick start with Pandas
import pandas as pd
df = pd.read_csv(
"costinflation-headache-allergy-heartburn-prices-2026-07-21-to-2026-08-18.csv",
dtype={"geography_id": "string", "series_id": "category"},
)
pain_relief = df.query("series_id in ['acetaminophen', 'ibuprofen']").dropna(
subset=["normalized_price_amount"]
)
print(pain_relief.groupby(["series_id", "geography_label"])["normalized_price_amount"].median())Quality and interpretation
- All 29 expected dates, all 12 ZIP markets, and all 1,392 category × ZIP × date cells are present.
- Exact duplicate public rows: 0.
- Formula-leading product titles: 0.
- Every nonblank comparable price has a positive resolved quantity compatible with the 100-unit target.
- Product titles are descriptive text, not stable public product identifiers.
- ZIP labels describe selected markets rather than citywide, metropolitan, state, or national estimates.
- Shipping, tax, redeemed promotions, purchases, clinical guidance, product performance, and coverage outside the selected ZIP panel are outside this dataset.
