Cold Chain Drugs List India — Which Medicines Must Be Refrigerated
Not all medicines can sit on an open shelf at room temperature. A significant number of medicines — from vaccines and insulins to certain eye drops and biological medicines — require continuous refrigeration between 2°C and 8°C to maintain their potency and safety. Failing to refrigerate these medicines can render them ineffective or even harmful to patients.
For Indian pharmacy owners, knowing which medicines belong in the refrigerator is both a compliance requirement and a patient safety obligation.
Legal basis: Cold chain requirements for medicines are mandated under the Drugs and Cosmetics Act, 1940, and the Drugs and Cosmetics Rules, 1945. Storing cold chain medicines outside required temperature ranges is a violation that can lead to licence suspension or cancellation.
How to Identify If a Medicine Needs Refrigeration
Check the medicine label and outer carton — they will state one of the following:
- "Store between 2°C and 8°C" — must be kept in a pharmacy refrigerator at all times
- "Store in a cool, dry place (below 25°C)" — room temperature is acceptable in most Indian conditions with air conditioning
- "Store below 30°C" — can be stored at Indian room temperature in most seasons
- "Store in a freezer (−20°C)" — requires a medical-grade freezer; rare in retail pharmacy
If a medicine says "2–8°C", it is a cold chain medicine — no exceptions. Even keeping it at 10°C or 15°C for a few hours can degrade its efficacy.
Complete Cold Chain Drugs List for Indian Pharmacies
1. Vaccines
All vaccines require cold chain. Most Indian pharmacies do not stock vaccines (they are administered in clinics and government centres), but if you do stock them for private immunisation clinics, all must remain at 2–8°C at all times.
| Vaccine | Storage | Notes |
|---|---|---|
| Hepatitis B vaccine | 2–8°C | Do not freeze |
| Typhoid Vi vaccine | 2–8°C | Shake before use |
| Varicella vaccine | 2–8°C or −15°C | Freeze or refrigerate depending on brand |
| HPV vaccine (Gardasil, Cervarix) | 2–8°C | Do not freeze; shake before use |
| Pneumococcal vaccine | 2–8°C | High-value; monitor temperature closely |
| Meningococcal vaccine | 2–8°C | Do not freeze |
| Influenza vaccine | 2–8°C | Seasonal; high demand Oct–Feb |
2. Insulin and Anti-Diabetic Biologics
| Medicine | Storage (Unopened) | Storage (After Opening) |
|---|---|---|
| Regular human insulin (e.g., Actrapid, Huminsulin R) | 2–8°C | Up to 28 days at room temp (below 25°C) |
| NPH insulin (e.g., Insulatard, Huminsulin N) | 2–8°C | Up to 28 days at room temp |
| Insulin glargine (Lantus, Basalog) | 2–8°C | Up to 28 days at room temp (below 30°C) |
| Insulin aspart (NovoRapid) | 2–8°C | Up to 28 days at room temp |
| Insulin lispro (Humalog) | 2–8°C | Up to 28 days at room temp |
| Insulin detemir (Levemir) | 2–8°C | Up to 42 days at room temp |
| Premix insulins (30/70, 50/50) | 2–8°C | Up to 28 days at room temp |
| Liraglutide (Victoza, Saxenda) | 2–8°C | Up to 30 days at room temp |
| Semaglutide injection (Ozempic) | 2–8°C | Up to 56 days at room temp (below 30°C) |
Key rule for insulin: Unopened insulin vials and pens must stay in the refrigerator. Once opened/in-use, most insulins can be kept at room temperature for 28 days. Inform patients of this when dispensing.
3. Eye Drops and Ophthalmic Preparations
| Medicine | Storage | Notes |
|---|---|---|
| Latanoprost eye drops (Xalatan) | 2–8°C (unopened); room temp after opening | One of the most commonly stocked refrigerated eye drops |
| Bimatoprost eye drops | Check label — some require refrigeration | Varies by brand and formulation |
| Human albumin eye drops | 2–8°C | Biological preparation |
| Autologous serum eye drops | −20°C (freezer) | Not commercially dispensed; made in hospitals |
| Cyclosporine eye drops (Restasis) | Check label | Some formulations require refrigeration |
4. Biological Medicines and Injectables
| Medicine Category | Examples | Storage |
|---|---|---|
| Erythropoietin (EPO) injections | Erythrogen, Epofit | 2–8°C; do not freeze |
| G-CSF (Granulocyte Colony Stimulating Factor) | Grafeel, Neukine | 2–8°C; do not freeze |
| Anti-thymocyte globulin | ATG, Thymogam | 2–8°C |
| Human immunoglobulin | Bivenum, Flebogamma | 2–8°C; do not freeze |
| Monoclonal antibodies | Trastuzumab, Bevacizumab | 2–8°C — typically hospital/oncology pharmacy |
| Streptokinase injection | Streptase | 2–8°C after reconstitution |
5. Antibiotic Injections and Reconstituted Suspensions
| Medicine | Refrigeration Required? | Notes |
|---|---|---|
| Amoxicillin + Clavulanic acid suspension (after mixing) | Yes — 2–8°C after reconstitution | Dry powder stored at room temp; only after water is added |
| Cefuroxime axetil suspension | Yes — 2–8°C after reconstitution | Discard unused portion after 10 days |
| Azithromycin suspension | Check brand label — varies | Most brands stable at room temp for 5 days |
| Cefpodoxime suspension | Yes — 2–8°C after reconstitution | Discard after 14 days |
Important for suspensions: Many antibiotic dry powders/granules are stored at room temperature before mixing. Once water is added (reconstituted), they must be refrigerated and discarded after a specified number of days — typically 7–14 days. Always check the inner label after mixing.
6. Hormone and Fertility Medicines
| Medicine | Storage |
|---|---|
| FSH injections (Gonal-F, Follistim, Ovafol) | 2–8°C; once opened may be at room temp for limited period |
| hCG injection (Pregnyl, Ovitrelle) | 2–8°C |
| Progesterone injection | Room temp; some preparations 2–8°C — check label |
| Somatropin (growth hormone) | 2–8°C; do not freeze |
| Teriparatide (Forteo, Teriparatide injection) | 2–8°C; use within 28 days after opening |
7. Other Medicines Requiring Refrigeration
| Medicine | Storage | Notes |
|---|---|---|
| Calcitonin nasal spray / injection | 2–8°C (unopened); room temp after opening nasal spray | Inject form always 2–8°C |
| Some suppositories | Below 25°C or 2–8°C — check label | Melt easily in Indian heat |
| Dried blood spot test kits | 2–8°C | Diagnostic, not medicine |
| Certain ear drops (biologicals) | Check label | Standard antibiotic ear drops do not require refrigeration |
Pharmacy Refrigerator Requirements Under Indian Law
Under the Drugs and Cosmetics Rules, 1945, every licensed pharmacy stocking cold chain medicines must have:
- A dedicated pharmaceutical refrigerator (not a domestic refrigerator used for food) — though many small pharmacies use domestic models in practice
- A calibrated thermometer — digital min/max thermometers are preferred
- Temperature log maintained twice daily (morning and evening) showing the minimum and maximum temperature recorded
- Refrigerator alarm or monitoring system for after-hours temperature excursions (required for Schedule X cold chain medicines)
The acceptable range is 2°C to 8°C. If the temperature goes above 8°C for more than 2 hours continuously, any cold-chain medicine stored should be quarantined and the manufacturer/supplier contacted before continuing to dispense.
Never freeze 2–8°C medicines. Freezing at 0°C or below destroys insulin, vaccines, and most biologicals — they cannot be refrozen and must be discarded. If your refrigerator is set too cold or the thermostat fails, the medicines are just as damaged as if they were stored too warm.
How to Manage Cold Chain Records
When you receive cold chain medicines from a supplier, you must verify and document:
- That the cold chain was maintained during transport — look for thermoindicator labels on packages (these change colour if temperature was exceeded)
- Time between supplier departure and your receiving — for long-distance deliveries, ask for temperature data logger printout
- Enter the receipt into your cold chain register with date, supplier, medicine name, batch, quantity, and temperature at receipt
