How to Identify the Manufacturer on Your Pack
1. Look at the label – The manufacturer’s name or company logo is usually printed on the blister pack or bottle.
2. Check the batch/lot number – Sometimes the manufacturer’s code is embedded in this number.
3. Use the drug’s code – In many countries, the national drug regulatory body (e.g., FDA in the U.S., EMA in the EU, CDSCO in India) assigns a unique code that links to the manufacturer.
Why This Matters
- Quality and consistency: Different manufacturers may use slightly different excipients or manufacturing processes, which can affect how the drug is absorbed or tolerated.
- Pricing: Generics from large multinational companies often come at a lower cost than branded versions.
- Availability: Some countries may have exclusive agreements with a particular manufacturer for specific formulations.
If you’re looking for a specific brand or formulation in your country, the best approach is to consult your local pharmacy or the national drug regulatory authority’s database. They can give you a definitive list of approved manufacturers for diclofenac in your region.
