How to Identify Generic Medicines: Label Reading, Verification and Safety Tips

Introduction

The rising cost of branded medicines has led many people to look for more affordable options. Generic medicines can be one such option. However, it is not always easy to recognise whether a medicine is a genuine generic medicine. A generic medicine has the same active ingredient as the branded medicine it is compared with and must meet required standards for quality, safety, strength and effectiveness¹. This guide explains how to identify, read, verify, and safely buy generic medicines. 

Why Is It Important to Identify Generic Medicines?

Identifying a generic medicine is an important first step in checking whether it is the right medicine for you. Here is why it matters: 

• Helps You Choose Affordable Medicines: Generic medicines are usually less expensive than their branded counterparts, making them a more affordable treatment option².
• Helps You Get the Right Medicine: Checking the generic name helps confirm the active ingredient and reduces the chance of taking the wrong medicine. 
• Makes It Easier to Compare Medicines: Knowing the generic name allows you to compare different products that contain the same active ingredient. 
• Helps with Long-Term Treatment Costs: Identifying generic options can reduce medicine expenses for people who need long-term treatment, making it easier for them to continue their medicines as prescribed³.
• Helps Prevent Duplicate Medicines: Checking the active ingredient can help you avoid accidentally taking two medicines that contain the same ingredient, such as a generic medicine and a branded version⁴.
• Helps Avoid Possible Allergies: Generic and branded medicines may contain different inactive ingredients. Checking these ingredients can help people with known allergies or sensitivities avoid ingredients that may trigger a reaction³.

How to Identify a Generic Medicine

Before using a medicine, take a few moments to check its label and compare it with your prescription. These steps can help you identify a generic medicine correctly: 

1. Look for the Active Ingredient 

Start by checking the medicine strip, bottle or box for the active ingredient. The active ingredient is the substance in the medicine that gives the desired effect. Generic medicines are usually identified by their active ingredient rather than a unique brand name².

2. Check the Medicine Strength 

Look at the strength mentioned next to the active ingredient, such as 500 mg or 10 mg. This helps you distinguish between medicines that contain the same ingredient but are available in different strengths¹. 

3. Look at the Dosage Form 

Check whether the medicine is a tablet, capsule, or syrup. The dosage form is important because medicines containing the same active ingredient may be available in different forms¹.

4. Match It with the Prescription 

If your doctor has prescribed a medicine by its generic name, compare the prescribed ingredient and strength with those printed on the medicine pack. This can help you identify whether you have received the intended medicine. 

Salt Name vs Brand Name

A medicine pack may show several names and details, which can make it confusing to know what you are taking. Understanding the difference between the brand name and the generic, or active ingredient, name can help you identify a medicine and compare products that contain the same ingredient. The table below explains common label details found on a medicine pack: 

Using the table as an example, Calpol is the brand name, while paracetamol is the generic or active ingredient name. The 500 mg shows the strength, and “tablet” describes the dosage form. 

Quick tip: The generic name may be printed near the brand name on a medicine box or strip. Look for terms such as “Composition”, “Each tablet contains”, “Active ingredient”, or “Salt composition”. The generic name may also be displayed prominently on the package, sometimes in a larger font than the brand name⁷. The ingredient name and its strength⁶, such as paracetamol 500 mg, tell you what active ingredient the medicine contains. 

Step-by-Step Medicine Identification Walkthrough

Information on a medicine package can help you find the generic name and strength. The examples below show what to look for: 

• Paracetamol: Look for the composition or active ingredient part. If you can see paracetamol 500 mg, paracetamol is the generic name, and 500 mg indicates its strength⁸. 
• Amoxicillin: Look for the ingredient list. If the label says Amoxicillin 500 mg, amoxicillin is the active ingredient and 500 mg is the amount present in each dose⁹.
• Cetirizine: Look for the medicine’s active ingredient on the packaging. If Cetirizine 10 mg is listed, cetirizine is the generic name, and 10 mg represents the medicine’s strength¹⁰.
• Metformin: Check the active ingredient list. If it states Metformin 500 mg, metformin is the generic name, and 500 mg tells the strength of the medicine¹¹.
• Omeprazole: Check the composition details printed on the medicine pack. If Omeprazole 20 mg is mentioned, omeprazole identifies the active ingredient, and 20 mg shows its strength¹².

Do not rely only on the large name printed on the front of the pack. Always check the active ingredient, strength, and dosage form to identify the medicine correctly. 

How to Verify a Generic Medicine 

After identifying a medicine by its active ingredient, strength and dosage form, check a few safety details before using it. 

• Check the Manufacturer: Look for the name of the company that made the medicine on the packaging. This helps you know who is responsible for manufacturing the product. 
• Check Regulatory Approval: Make sure the generic medicine is approved by the appropriate regulatory authority. Approved generics must meet the required standards for quality, safety and effectiveness¹.
• Check the Batch Number and Expiry Date: Find the batch number and expiry date printed on the pack. Do not use a medicine that has passed its expiry date or has damaged or unclear packaging¹³.
• Check the Packaging: Make sure the pack is properly sealed and does not appear damaged, opened, or altered. If anything looks unusual, ask a pharmacist before using it. 
• Compare It with Your Prescription: Once again, compare the medicine name, active ingredient, and strength with your prescription. If anything is different or unclear, check with your doctor or pharmacist before taking it. 

Generic Medicine vs Branded Medicine

The table below explains key differences between generic and branded medicines in simple terms. 

Common Mistakes People Make While Identifying Generic Medicines

People may make the following mistakes when trying to identify generic medicines: 

• Confusing the Brand Name with the Generic Name: A brand name may be different from the medicine’s generic name or the group of medicines it belongs to¹⁵.
• Focusing Only on Appearance: A generic medicine may have a different colour, shape, size or packaging from the branded version, even when it has the same active ingredient and strength³.
• Ignoring the Medicine Strength: When choosing medicines, it is important to look for the strength of the medicine, such as 500 mg or 10 mg⁶.

Tips for Buying Generic Medicines Safely

Use these tips to buy generic medicines more safely: 

• Choose a reliable pharmacy when buying medicines, including online. 
• Make sure the generic name, strength and dosage form match your prescription².
• Make sure the package is sealed, undamaged and not expired¹³. 
• Be careful if a medicine is offered at a price that seems unusually low, especially by an unfamiliar seller. 

Conclusion

Knowing the generic name, strength and dosage form can help you understand the medicine you are buying. Checking the label, packaging and prescription can help you choose the right medicine more safely. If you are unsure about a generic medicine, speak with your doctor or pharmacist before buying it or switching from another medicine.
