Schedule G Drugs in India: Drugs Under Medical Supervision Only
Guide to Schedule G drugs under the Drugs and Cosmetics Rules -- drugs that must be taken only under medical supervision, with examples, labelling rules and exam relevance.
What Are Schedule G Drugs?
Schedule G of the Drugs and Cosmetics Rules, 1945 lists drugs that, while not requiring the same level of prescription control as Schedule H or X, must be used only under medical supervision. These are drugs where the therapeutic benefit requires proper dosage adjustment, monitoring for adverse effects, or clinical oversight that a patient cannot reliably provide on their own.
The regulatory intent behind Schedule G is to ensure that certain drugs with a narrow therapeutic index, significant side effects, or complex dosing requirements are used with appropriate medical guidance, even if the prescription controls are less stringent than Schedule H.
Legal Framework and Requirements
Under the Drugs and Cosmetics Rules, Schedule G drugs must carry the following warning on their label: "Caution: It is dangerous to take this preparation except under medical supervision." This warning must appear on the innermost container and every outer covering.
Unlike Schedule H drugs, Schedule G drugs do not strictly require a written prescription for sale in all cases. The legal obligation is on the labelling and on the pharmacist to counsel the buyer that medical supervision is necessary. However, in practice, many Schedule G drugs are also listed under Schedule H, creating an overlap where the stricter requirement prevails.
Common Schedule G Drugs with Examples
Schedule G includes a range of hormonal preparations, anti-infective agents and other therapeutically important drugs:
- Testosterone (brand names: Sustanon, Cernos, Testoheal) -- an androgen for hormone replacement
- Progesterone (brand names: Susten, Gestone, Naturogest) -- a progestogen for hormonal support
- Estradiol (brand names: Progynova, Evalon, Estraderm) -- an estrogen for hormone replacement
- Tolbutamide (brand names: Rastinon, Orinase) -- a first-generation sulfonylurea
- Chlorpropamide (brand names: Diabinese, Copamide) -- a sulfonylurea oral hypoglycaemic
- Phenytoin (brand names: Eptoin, Dilantin, Fosphen) -- an anticonvulsant with a narrow therapeutic index
- Ergotamine (brand names: Cafergot, Ergomar, Migranal) -- used for migraine
- Thyroid extract (brand names: Thyroid Extract BP, various) -- used for hypothyroidism
- Hydrochlorothiazide (brand names: Aquazide, Esidrex, HydroDiuril) -- a thiazide diuretic
- Spironolactone (brand names: Aldactone, Spiromide, Lasilactone) -- a potassium-sparing diuretic
- Sulphasalazine (brand names: Salazopyrin, Sazo, Sulfazine) -- used in inflammatory bowel disease
- Chloroquine (brand names: Lariago, Resochin, Aralen) -- an antimalarial
- Primaquine (brand names: Malirid, Primaquine Phosphate) -- an antimalarial
- Clomiphene citrate (brand names: Clofert, Siphene, Fertomid) -- an ovulation-inducing agent
- Tamoxifen (brand names: Mamofen, Nolvadex, Tamodex) -- a selective estrogen receptor modulator
Prescription and Dispensing Requirements
The dispensing requirements for Schedule G drugs are less stringent than Schedule H. The primary legal requirement is the warning label on the packaging. Pharmacists are expected to inform buyers that the drug should be taken under medical supervision, but a written prescription is not mandated by Schedule G classification alone.
However, this distinction is largely theoretical. Most Schedule G drugs are also listed under Schedule H or H1, which imposes the prescription requirement. Where a drug appears in both schedules, the more restrictive requirement applies. Students should be aware that Schedule G is primarily a labelling schedule rather than a dispensing control schedule.
Record-Keeping Obligations for Pharmacists
Schedule G does not impose specific record-keeping requirements beyond the general obligations under the drug licence conditions. Pharmacists must maintain standard sales records and purchase registers as required by their state drug licence, but there is no separate Schedule G register equivalent to the Schedule H1 register.
Where a Schedule G drug is also listed under Schedule H1, the H1 record-keeping requirements apply in full. Pharmacists should check whether each Schedule G drug has additional schedule classifications before deciding on documentation requirements.
Penalties for Violations
Violations related to Schedule G drugs primarily involve labelling failures -- selling a Schedule G drug without the required warning on the label. Under Section 18 of the Drugs and Cosmetics Act, this constitutes a violation of labelling requirements and can attract imprisonment of up to one year, a fine, or both for first offences.
Manufacturers who fail to include the Schedule G warning on their packaging face more serious consequences, including potential recall of the affected batches and suspension of the manufacturing licence.
Relevance to NEET PG and Pharmacology Exams
Schedule G is less frequently tested than Schedules H, H1 and X, but it does appear in NEET PG and FMGE papers. The key exam points are the specific warning label text ("Caution: It is dangerous to take this preparation except under medical supervision"), the distinction from Schedule H (warning vs. prescription requirement), examples of drugs that are Schedule G but not Schedule H (though this category is shrinking), and the concept that Schedule G is primarily a labelling requirement.
A common exam question format presents a warning label and asks students to identify which schedule it belongs to. Knowing the exact wording for G, H and H1 is essential.
Recent Updates and Changes
The practical significance of Schedule G as a standalone category has diminished over time as most Schedule G drugs have been brought under Schedule H or H1 as well. The government has not recently added new drugs to Schedule G without also placing them under a higher schedule.
There have been periodic discussions about rationalising the schedule system to eliminate overlaps, but no formal amendment has been made. CDSCO continues to list Schedule G separately in the rules, and the labelling requirement remains in force.

Frequently Asked Questions
What is the warning label required on Schedule G drugs?
The label must state: 'Caution: It is dangerous to take this preparation except under medical supervision.' This must appear on the innermost container and every outer covering of the drug.
Do Schedule G drugs require a prescription?
Schedule G itself does not mandate a written prescription -- it requires a warning label advising medical supervision. However, most Schedule G drugs are also listed under Schedule H or H1, where a prescription is mandatory. Where a drug appears in multiple schedules, the stricter requirement applies.
What is the difference between Schedule G and Schedule H?
Schedule G requires a warning label stating the drug should be taken under medical supervision. Schedule H requires the drug to be sold only on the prescription of a Registered Medical Practitioner. Schedule H is stricter -- it mandates a prescription, while Schedule G mandates a warning.
Are hormonal drugs typically Schedule G?
Yes, many hormonal preparations -- including testosterone, estradiol, progesterone and clomiphene -- are listed under Schedule G. These drugs require dosage adjustment and monitoring that necessitates medical supervision, which is the core rationale of Schedule G.
Is Schedule G still relevant for pharmacology exams?
Yes, though it is tested less frequently than Schedules H, H1 and X. NEET PG and FMGE questions typically test the exact warning label text, the distinction from other schedules, and examples of Schedule G drugs. It is important to know that Schedule G is primarily a labelling schedule.
