Complete Guide to Indian Drug Schedules: All Schedules Under the Drugs and Cosmetics Act Compared
A comprehensive comparison of all drug schedules under India's Drugs and Cosmetics Act, 1940 -- Schedule G, H, H1, X, E, J and more, with a quick-reference comparison table.
Overview of Drug Scheduling in India
India's drug regulatory framework is built on the Drugs and Cosmetics Act, 1940 and the Drugs and Cosmetics Rules, 1945, administered by the Central Drugs Standard Control Organisation (CDSCO) under the Ministry of Health and Family Welfare. The scheduling system classifies drugs based on their risk profile, determining the level of control required for their manufacture, sale, distribution and use.
Understanding drug schedules is essential for medical professionals, pharmacists and students preparing for NEET PG, INI-CET, FMGE and other medical examinations. Each schedule carries specific obligations for labelling, prescribing, dispensing, record-keeping and storage.
Schedule C and C1: Biological and Special Products
Schedule C lists biological and special products such as sera, vaccines, toxins, antigens and similar products of biological origin. Schedule C1 lists other special products including blood products, intravenous fluids, and certain sterile preparations. These schedules do not directly affect prescription requirements but impose strict manufacturing, testing, storage and transportation standards.
Key requirements include cold chain maintenance for biological products, batch testing and release by the Central Drugs Laboratory (CDL) in Kasauli, and specific shelf-life limitations.
Schedule D: List of Drugs Exempt from Certain Provisions
Schedule D contains a list of drugs that are exempt from certain provisions of the Drugs and Cosmetics Rules. These include traditional medicines, homeopathic preparations, and certain Ayurvedic, Siddha and Unani products that are regulated under separate chapters of the Act.
This schedule has limited exam relevance but is important for understanding the regulatory distinction between allopathic drugs and traditional medicine systems in Indian law.
Schedule E and E1: Poisons
Schedule E lists poisonous substances used in Ayurvedic and Siddha medicines, specifying which substances must undergo purification (Shodhana) before use. Schedule E1 lists poisonous substances used in allopathic medicine, specifying maximum single doses and maximum 24-hour doses.
Key feature: The pharmacist must verify that prescriptions do not exceed the specified maximum dose. If a prescription exceeds the limit, the pharmacist must contact the prescriber for confirmation before dispensing.
Schedule G: Drugs Requiring Medical Supervision
Schedule G drugs must carry the warning: "Caution: It is dangerous to take this preparation except under medical supervision." This is primarily a labelling requirement rather than a prescription control. Most Schedule G drugs are also listed under Schedule H, where the prescription requirement supersedes the warning label.
Examples include hormonal preparations (testosterone, estradiol, progesterone), certain oral hypoglycaemics (tolbutamide, chlorpropamide), and antimalarials (chloroquine, primaquine).
Schedule H: Prescription-Only Drugs
Schedule H is the standard prescription-only category. Drugs in this schedule can only be sold on the prescription of a Registered Medical Practitioner. The label must state: "Schedule H Drug -- Warning: To be sold by retail on the prescription of a Registered Medical Practitioner only."
This is the largest drug schedule and covers most prescription drugs used in modern medicine, including antibiotics, antihypertensives, antidiabetics, NSAIDs (prescription-strength), cardiovascular drugs, and most other therapeutic classes.
Schedule H1: Stricter Prescription Control with Record-Keeping
Schedule H1, introduced in 2013, is a subset of Schedule H with additional requirements. The key distinction is mandatory record-keeping by the pharmacist -- a register must be maintained with the details of the prescriber, patient, drug and quantity for every Schedule H1 transaction. This register must be kept for three years.
Schedule H1 was introduced primarily to combat antimicrobial resistance (AMR) and misuse of habit-forming drugs. It covers third-generation cephalosporins, fluoroquinolones, anti-tuberculosis drugs, certain antiretrovirals, and habit-forming substances like codeine-containing preparations.
Schedule X: Narcotic and Psychotropic Drugs (Highest Control)
Schedule X represents the highest level of prescription drug control under the Drugs and Cosmetics Rules. Key requirements include prescriptions in duplicate, separate locked storage, a dedicated sales register (distinct from the H1 register), no refills without a new prescription, and quantity specified in words and figures.
Schedule X drugs include opioid analgesics (morphine, fentanyl, pethidine), benzodiazepines (diazepam, alprazolam, lorazepam), barbiturates (phenobarbital), and other drugs with high abuse potential. Many Schedule X substances are also controlled under the NDPS Act, 1985.
Schedule J: Diseases (Not Drugs)
Schedule J is unique in that it lists diseases and conditions, not drugs. No person can advertise any drug as a cure, treatment or prevention for Schedule J diseases. This schedule is enforced through the Drugs and Magic Remedies (Objectionable Advertisements) Act, 1954.
Schedule J covers cancer, diabetes, cardiovascular diseases, epilepsy, HIV/AIDS, tuberculosis, infertility, blindness, deafness, baldness, obesity and many other serious conditions.
Quick Comparison Table
The hierarchy from least to most restrictive is: OTC (no schedule) < Schedule G (warning label) < Schedule H (prescription required) < Schedule H1 (prescription + pharmacist records) < Schedule X (duplicate prescription + locked storage + dedicated register).
Key distinguishing features at each level:
OTC: No prescription needed. Can be sold from any licensed pharmacy. Examples: paracetamol, cetirizine, antacids.
Schedule G: Warning label required ("under medical supervision"). No mandatory prescription by the schedule itself. Examples: hormonal preparations, antimalarials.
Schedule H: Prescription from RMP required. Standard labelling. No special record-keeping beyond normal sales records. Examples: most antibiotics, antihypertensives, antidiabetics.
Schedule H1: Prescription required PLUS pharmacist must maintain a register (prescriber name, patient name, drug, quantity, date) for 3 years. Introduced 2013 for AMR control. Examples: fluoroquinolones, cephalosporins, anti-TB drugs.
Schedule X: Prescription in DUPLICATE. Separate LOCKED storage. Dedicated register. No refills. Dose in words AND figures. Examples: morphine, diazepam, fentanyl, alprazolam.
Related Legislation
Beyond the Drugs and Cosmetics Act, several other laws interact with drug scheduling:
NDPS Act, 1985: Governs narcotic drugs and psychotropic substances with criminal penalties far exceeding those under the DCA. Many Schedule X drugs are also controlled under NDPS.
Essential Commodities Act, 1955: The legal basis for DPCO 2013, which empowers NPPA to fix ceiling prices for NLEM drugs.
Drugs and Magic Remedies (Objectionable Advertisements) Act, 1954: Enforces Schedule J advertising restrictions.
Pharmacy Act, 1948: Regulates the pharmacy profession and establishes the Pharmacy Council of India, which sets standards for pharmacy practice including dispensing of scheduled drugs.
Relevance to NEET PG and Pharmacology Exams
Drug schedules are among the most frequently tested topics in pharmacology and forensic medicine for NEET PG, INI-CET and FMGE. A systematic approach to learning includes memorising the warning label text for Schedules G, H, H1 and X (each is different), knowing 10-15 examples for each schedule, understanding the record-keeping requirements (none for H, register for H1, dedicated register + duplicate Rx for X), knowing the year H1 was introduced (2013) and its rationale (AMR), understanding Schedule J as a disease list and advertising restriction, and knowing the role of NPPA (prices) vs CDSCO (quality and scheduling).
Common exam traps include confusing Schedule H and H1 requirements, not knowing that Schedule G is primarily a labelling schedule, not recognising that Schedule J lists diseases rather than drugs, and confusing DCA penalties with NDPS Act penalties for Schedule X substances.
Recent Updates and Regulatory Trends
The Indian drug scheduling system continues to evolve. Key trends include progressive expansion of Schedule H1 to cover more antibiotics as part of AMR control, ongoing work on formalising an OTC drug list, digital record-keeping options for Schedule H1 compliance, proposed E-Pharmacy Rules for online drug sales, and harmonisation of Indian schedules with WHO Model List classifications.
Students should stay updated on CDSCO gazette notifications that add or remove drugs from schedules, as these changes can appear in exam questions within a year of implementation.

Frequently Asked Questions
How many drug schedules are there under the Drugs and Cosmetics Rules?
The Drugs and Cosmetics Rules, 1945 contain multiple schedules: C, C1, D, E, E1, F, FF, G, H, H1, J, K, M, N, O, P, Q, R, S, T, U, V, W, X and Y. For pharmacology exam purposes, the most important are G, H, H1, X, E/E1 and J. Each serves a different regulatory purpose -- from manufacturing standards to prescription controls to advertising restrictions.
Which schedule has the strictest controls?
Schedule X has the strictest prescription and dispensing controls within the Drugs and Cosmetics Rules. It requires prescriptions in duplicate, separate locked storage, a dedicated sales register, no refills without a new prescription, and dose written in words and figures. Where a drug is also covered by the NDPS Act, 1985, even stricter criminal law provisions apply.
What is the correct hierarchy of drug schedules from least to most restrictive?
From least to most restrictive: OTC (no schedule, no prescription needed) < Schedule G (warning label only) < Schedule H (prescription required) < Schedule H1 (prescription + mandatory pharmacist record-keeping) < Schedule X (duplicate prescription, locked storage, dedicated register, no refills).
Can a drug be listed in multiple schedules?
Yes. Many drugs appear in more than one schedule. For example, a drug can be in both Schedule G and Schedule H (like some hormonal preparations). When a drug appears in multiple schedules, the more restrictive requirements apply. Most Schedule G drugs are also in Schedule H, making the prescription requirement (H) the operative rule.
Which drug schedule topics are most important for NEET PG?
For NEET PG, the most frequently tested topics are: (1) Schedule H vs H1 differences, (2) Schedule X requirements, (3) Schedule J as a disease list, (4) Schedule E1 maximum dose limits, and (5) the labelling text for each schedule. Students should also know the role of CDSCO, NPPA, and the relationship between the DCA and the NDPS Act.
