Counterfeit medicines are becoming increasingly problematic as they often contain no active ingredients and can be hazardous to consumers. Patients depend on medicines to treat illnesses and control their symptoms. However, misleading patients by providing them with fake medicines that may not contain any active ingredients or may contain ingredients that could be harmful, is a crime. Counterfeit medicines often look like the real thing and may be difficult to identify.
Being able to identify counterfeit medicines is imperative to protect you and your family. This guide explains counterfeit medicines in detail, including signs, effects, types, and how to differentiate between the real and fake medicines.

What Are Counterfeit (Fake) Medicines?
Counterfeit medicines are medical products that are deliberately misrepresented in terms of their identity, composition, or source. They are manufactured or distributed with the intent to defraud and deceive the consumer into believing they are purchasing a real medicine.
Various dangerous substances or no active pharmaceutical ingredient at all may be present in a counterfeit product. Counterfeit medicines may take different forms, such as tablets, capsules, syrup, injection or creams.
Not every poor quality medicine is counterfeit. Other reasons, like manufacturing or storage errors may cause medicines to not meet the quality standards.
Types of Fake Medicine
Counterfeit medicines can take various forms depending on how they are produced and how they are deliberately misrepresented.
Medicines with no Active Ingredients
These look similar to the genuine medicines but have no active pharmaceutical ingredients, and therefore cannot have the intended therapeutic benefit. Patients may have worsening symptoms.
Medicines with Incorrect Active Ingredients
Other fake medicines may have ingredients different from what is mentioned on their labels, and may cause unexpected reactions, including allergic ones.
Medicines with Incorrect Dosage
These fake medicines may have the required active ingredients, but are in incorrect doses. Less than the required dose may fail to give the intended therapeutic benefit, and more than the required dose may lead to toxicity.
Medicines with Correct Packaging
Counterfeit medicines may also contain the correct ingredients, but are packaged in counterfeit packaging which resembles the genuine packaging.
Expired or illegally relabeled medicines
Some medicines may have their expiry dates changed and/or their labels changed to mislead the consumers, and are, therefore, falsified medicines. Expired medicines, in and of themselves, are not counterfeit medicines.

Characteristics of Fake Medicine
Understanding the characteristics of fake medicine will allow end users to identify suspicious products before consumption.
Poor Packaging Quality
Damaged packaging may indicate that fake medicine is packaged in poor quality material. Poor packaging can also include unclear printing, spelling mistakes and inconsistencies in font style and size.
Missing or Suspicious Information
Packaging of real medicine provides a variety of important information including, the name of the medicine, strength, batch number, expiration date and the manufacturer information. Proper batch number and expiry date tracking is also important for identifying expired or questionable stock before it reaches consumers.
Unusual Appearance
There are several appearance related signs that may indicate a medicine is fake, including discoloration of tablets and liquids, unexpected textures, or unexpected contents.
Suspiciously Low Prices
Prices of medicines below the expected range may indicate a product is fake. However, relatively low prices of medicines, including real generic alternatives, should not be regarded as a sign of a product being fake.
Unverified Sellers
Reduced risk of purchasing a fake medicine is achieved by purchasing from a licensed pharmacy. The opposite is true by purchasing from unlicensed suppliers (unauthorized websites, social media, etc.).Pharmacies can also improve stock traceability through proper pharmacy inventory and stock management, including batch records and expiry monitoring.
How to Identify Fake Medicine?
Identifying counterfeit medicines is complicated and requires thorough analysis. There are multiple ways to help assess potentially unsafe medicines.
- Assess the packaging: Check for spelling errors and other anomalies in the printing, damaged seals, and differences from previous packages.
- Assess the medicine details: Check the product name, strength, batch number, the date and place of manufacturing and the expiration date.
- Assess the medicine: Look for changes in appearance and odor, and check for broken tablets and/or particles in the liquid.
- Assess security features: Check for any verification codes, tamper-evident seals or other verification systems provided by the manufacturer. Remember that security features can also be replicated.
- Buy medicine only from licensed pharmacies: Do not buy from unlicensed suppliers and sellers.
- Contact a pharmacist: If you are not sure about a medicine, ask a pharmacist to assist you.
Important: The appearance of the medicine cannot confirm its genuineness. Professional verification and/or laboratory testing may be required.
Fake Medicine Side Effects
The consequences of fake medicines range from no effect to inadequate treatment to the worsening of conditions. Ultimately, the use of counterfeit medicines can have serious health consequences, including death. Medication safety also involves checking prescriptions for potential drug interactions and other risks before medicines are dispensed.
Treatment Failure
Medicines that do not contain the correct or required amount of active pharmaceutical ingredients can be completely ineffective in providing treatment. Persons using these medicines may not benefit from treatment and may continue to be a reservoir of infection for others.
Serious Side Effects
The presence of incorrect and unacceptable ingredients in medicines, or the absence of any active ingredients, may result in a range of adverse effects including poisoning and organ damage.
Drug Resistance
Use of insufficient medicines to treat infections may lead to drug resistance, which in turn can make future treatment of the same infections even more difficult.
Delayed Medical Treatment
Use of counterfeit medicines can instill a false sense of security in patients which results in a delay in the seeking of appropriate medical care.
Financial and Psychological Stress
The purchase of ineffective medicines can be financially draining on patients and increases the stress already experienced by patients and their caregivers.
Conclusion
Using fake medicines poses a serious risk to the safety of patients and the health of the general public. Understanding the types, characters and effects of counterfeit medicines will empower the consumer to make an informed choice when buying medicine.
To limit your exposure to counterfeit medicines you should purchase your medicine from a licensed pharmacy. Always check the medicine package to make sure details printed on the package are correct. Avoid un-verified medicine sellers. And lastly, if you are not sure about the medicine you are taking, always seek help from a health care professional.
Do not take medicine you suspect to be counterfeit. If you suspect the medicine to be counterfeit and it is for a serious health condition you should inform the medical regulatory authority.
