Part 1: Schedule H — India’s Standard Prescription Drug Classification

Legal Disclaimer: This guide is for educational and informational purposes only. It does not constitute medical or legal advice.

Schedule H is the foundational tier of prescription-only medicines in India. It was established under the Drugs and Cosmetics Rules, 1945 and forms the baseline regulatory control for thousands of medications that cannot be sold over the counter (OTC).

What is Schedule H?

Schedule H is a list of drugs that can only be sold by a licensed pharmacist upon receiving a valid prescription from a Registered Medical Practitioner (RMP). These drugs are considered too potent, too dangerous, or too easy to misuse for a patient to self-prescribe.

Labeling Requirements

Every Schedule H drug must display the following on its packaging:

• The symbol “Rx” printed prominently in red on the left-hand top corner of the label.
• A warning box stating: “Schedule H Drug — Warning: To be sold by retail on the prescription of a Registered Medical Practitioner only.”

The Reality in India

Despite the legal requirements, the enforcement of Schedule H is notoriously lax in India. A 2019 study published in the Indian Journal of Pharmacology found that a majority of retail pharmacies in urban and semi-urban India dispense Schedule H drugs without requiring a prescription. This rampant over-the-counter sale of prescription drugs is a major driver of antimicrobial resistance and accidental drug interactions.

Common Categories of Schedule H Drugs

Schedule H is a massive list. Here are the most commonly encountered categories:

1. Antibiotics (Non-H1)

• Amoxicillin, Azithromycin, Ciprofloxacin, Doxycycline, Metronidazole.
• Why Rx?: Irrational antibiotic use drives antimicrobial resistance (AMR), creating “superbugs.”

2. Antihypertensives (Blood Pressure)

• Amlodipine, Telmisartan, Losartan, Atenolol, Enalapril.
• Why Rx?: Incorrect dosing can cause fatal drops in blood pressure or kidney damage.

3. Antidiabetics

• Metformin, Glimepiride, Sitagliptin, Insulin (all forms).
• Why Rx?: Incorrect use can cause fatal hypoglycemia (blood sugar crashing to dangerous levels).

4. Antidepressants & Antipsychotics

• Escitalopram, Fluoxetine, Sertraline (Schedule H, but many are also H1).
• Olanzapine, Quetiapine, Risperidone.
• Why Rx?: These alter brain chemistry and require psychiatric supervision to prevent dangerous side effects.

5. Corticosteroids

• Prednisolone, Dexamethasone, Betamethasone.
• Why Rx?: Long-term unsupervised use causes Cushing’s syndrome, osteoporosis, and adrenal suppression.

6. NSAIDs (Prescription-Strength)

• Diclofenac (injection), Piroxicam, Ketorolac.
• Why Rx?: These cause gastrointestinal bleeding and kidney damage with chronic use.

7. Cardiac Drugs

• Warfarin, Digoxin, Amiodarone, Propranolol.
• Why Rx?: Narrow therapeutic index — a tiny overdose can cause fatal heart arrhythmias.
