Medication Consultation


Under the inner packaging of the product, there is a row labeled "LOT NO." I have purchased two boxes with the same lot number.
However, I dissolved one capsule from each box in water, and both started to dissolve at around 20 seconds.
I am concerned that I may have bought a counterfeit product.
Please help me clarify my doubts.

More Info


Verifying the authenticity of your medication is crucial for ensuring safety and efficacy. Here’s a comprehensive guide to help you determine whether your medication is genuine.


1. Check Packaging and Labels
- Look for Tamper-Evident Seals: Authentic medications usually come with tamper-proof packaging. If the seal is broken or missing, it could indicate that the product has been compromised.

- Inspect the Label: Ensure that the label includes the correct spelling of the drug name, dosage, and manufacturer information. Look for any discrepancies or unusual fonts that might suggest counterfeit products.


2. Examine the Lot Number
- Understanding Lot Numbers: The "LOT NO." you mentioned is a unique identifier assigned to a batch of medication. This number can be used to trace the product back to the manufacturer. If you have multiple boxes with the same lot number, it’s not inherently suspicious, as medications are often produced in batches.

- Contact the Manufacturer: If you have concerns about the authenticity of the medication, you can contact the manufacturer directly with the lot number. They can confirm whether that lot was produced and if there have been any recalls or issues associated with it.


3. Dissolution Test
- Dissolution Rate: You mentioned that you dissolved a pill in water and observed it starting to dissolve within 20 seconds. While this can be a preliminary test, it’s not definitive proof of authenticity. Different formulations can have varying dissolution rates, and counterfeit medications may also dissolve similarly.

- Consult a Pharmacist: If you have concerns about the dissolution rate, consult a pharmacist. They can provide insights into the expected dissolution characteristics of the medication you have.


4. Verify with a Pharmacist
- Professional Insight: Pharmacists are trained to recognize authentic medications. Bring your medication to a pharmacy and ask the pharmacist to verify its authenticity. They can check for proper packaging, labeling, and any known issues with the specific medication.


5. Use Technology
- Mobile Apps and Websites: Some pharmaceutical companies and health organizations provide apps or websites where you can verify the authenticity of medications by entering the lot number or barcode. Check if the manufacturer of your medication offers such a service.


6. Purchase from Reputable Sources
- Avoid Unverified Sellers: Always purchase medications from licensed pharmacies or reputable online retailers. Be cautious of purchasing medications from unknown sources, as they may sell counterfeit products.

- Check for Licensing: If you are buying medication online, ensure that the pharmacy is licensed and requires a prescription for prescription medications.


7. Report Concerns
- Adverse Effects: If you suspect that you have received counterfeit medication or if you experience unusual side effects, report your concerns to your healthcare provider and the appropriate regulatory authority (such as the FDA in the United States). They can investigate and take necessary actions.


Conclusion
Your health and safety should always be your top priority. While it’s understandable to be concerned about the authenticity of your medication, following these steps can help you verify its legitimacy. If you ever have doubts, don’t hesitate to reach out to a healthcare professional for guidance. Remember, it’s better to be cautious and ensure that you are taking safe and effective medications.
