Background: Package inserts (PIs) serve detailed information on drug products to the users and primary care physicians, so information should be accurate, reliable, and as per the regulatory guidelines. The study aims to analyze the information adequacy of the PIs available in the Indian market as per Drug and Cosmetic Rule 1945 and US Food and Drug Administration criteria. Materials and Methods: A cross-sectional study was conducted on PIs collected from accessible pharmacy stores. Information provided was recorded as per criteria, and total information adequacy score (IAS) and information deficiency (IDS) score were calculated. The association of factors like single-drug/FDCs, a company of origin Indian/multinational, and route of administration (ROA) with IDS was statistically analyzed. Results: Of 120 PIs, 60%, 86.66%, and 73% were single-drug, prescription-drug, and drugs by Indian manufacturers, respectively. Most PIs provided generic names, ROA, and indications for use. 85%, 12%, 29.16%, and 3.33% provided information on PIs on the ability to drive, drug–food interactions, drug–drug interactions, and addiction potential, respectively. Lacking area was information on use in pediatrics–geriatrics (30%), excipients (28.3%), preclinical (15.83%), post-surveillance data (18.33%), and approval date (2.5%). There was a statistically significant difference between pharmaceutical score (3.22 vs 4.12), therapeutic score (11.5 vs 13.18), and total IAS (14.78 ± 3.39 vs 17.31 ± 2.33) of Indian and multinational companies. IDS was statistically significantly different in both pharmaceutical and therapeutic categories for single-drug vs FDCs (P = 0.00001), OTC vs prescription drugs (P < 0.05), and Indian vs multinational companies’ PIs (P = 0.00001). Conclusion: Numerous facets of information are lacking in PIs, and they do not impart whole information, especially of Indian origin, as per objective IDS.
