No. Sig's Drug Interactions tool is a label check, not a severity-rated interaction database. Sig reads the current FDA label of each drug on a list, then finds mentions of the other drugs by name or by drug class. The FDA table of CYP and transporter substrates, inhibitors, and inducers backs the class matching.

For example, with simvastatin and clarithromycin on the same list, Sig shows the label sections of each drug mentioning the other or the other's class. Sections are quoted and ranked, with Contraindications before Drug Interactions. Additionally, our data add 1,499 rows of interaction guidance from HHS guideline tables, as of November 3, 2026.

The tool needs a connection to fetch labels from openFDA, and a drug with no openFDA label returns nothing. The list is kept for the session only and is never saved or sent anywhere else. Sig states the limits on the tool's own Sources and Limits page.

Yes. Sig's Pill Identifier searches 19,925 products by imprint, colour, and shape, or reads a photo of the tablet on the device. Scan Package reads the barcode on a box or takes a typed NDC and opens the current FDA label.

Images are analyzed on the device and are never saved to the photo library or uploaded.

For example, a pharmacist holding an unlabeled tablet can type the imprint and choose the colour and shape. Sig then lists each matching product with strength, labeler, and NDC. According to the app's sources, the imprint, colour, shape, score, and size data come from Structured Product Labeling published through DailyMed.

Our data come from the DailyMed archive of August 23, 2026. Additionally, imprints vary by manufacturer, so a match should always be confirmed against the dispensed product.

Yes. Sig bundles the FDA Orange Book edition of October 9, 2026. The Orange Book data include 48,865 products, therapeutic equivalence (TE) codes, reference listed drugs, 22,438 patents, and exclusivity. Sig also bundles the FDA Purple Book September 2026 release, with 2,251 biologic products, 100 biosimilars, and 146 interchangeables.

For example, opening a generic in the Orange Book shows the TE code, such as AB, and the reference listed drug the generic was rated against. Opening a biologic in the Purple Book shows the reference product and every biosimilar or interchangeable licensed against the reference, with what substitution means for each.

Additionally, pharmacists using Sig open both books from the Book button on the monograph of any listed drug, and both books work offline. Our data come from the FDA's own published files, and the edition date is shown in the app.

Yes. Sig's Controlled Substances tool lists 631 federal substances with DEA schedules, according to 21 CFR Part 1308 and 21 U.S.C. § 812. The tool adds the schedules of all 50 states and where each state differs from the federal list. Every entry is tied to the statute or rule cited.

For example, where a state schedules a substance differently from the DEA, Sig shows the state schedule with the statute setting the schedule. The tool also covers prescription rules from 21 CFR Part 1306 and who may prescribe controlled substances across ten professions in every state.

Additionally, pharmacists using Sig's DEA Number Check can validate a DEA registration number's letters and check digit, following the method in the DEA's own manual. The number is checked on the device and is never sent anywhere.

Our data for the federal and state schedules are current as of October 9, 2026.

Yes. Sig Translator is a tool for turning prescriber shorthand into plain patient directions. For example, "1 tab po bid x10d" becomes "Take 1 tablet by mouth twice a day for 10 days." Each expanded abbreviation is listed under the result, so a pharmacist using Sig Translator can see exactly how the label text was built.

The abbreviation table comes from named references, including the Joint Commission "Do Not Use" list, the ISMP List of Error-Prone Abbreviations, Symbols, and Dose Designations, FDA guidance on container labeling, and USP General Chapter <17> on prescription container labeling.

Our data draw on 10 published references for the abbreviations and the label wording, as of November 3, 2026.

Additionally, Sig Translator reads common pharmacy shortcut codes. The Day Supply tool then calculates days supply and NCPDP billing units for insulin pens, eye drops, inhalers, and topicals across 144 products, each tied to a published reference.
