Unlike genuine medicines, counterfeit GLP-1 drugs do not go through strict quality checks. Dr Bansal explains that fake injections may contain incorrect ingredients, unsafe contaminants, or the wrong amount of medicine. In some cases, they may not contain the active drug at all. This means patients may believe their treatment is working while their diabetes or obesity continues to worsen. Contaminated products can also trigger allergic reactions, infections, or other serious side effects.

Authentic GLP-1 medicines are prescription drugs. Be cautious if they are sold at unusually low prices, promoted through social media ads or direct messages, or offered without a valid prescription. These are common warning signs of counterfeit medicines.

Before opening the medicine, inspect the box closely. Watch for spelling mistakes, poor-quality printing, damaged or broken seals, missing batch numbers, or missing expiry dates. Dr Bansal says, "These packaging errors can indicate a fake product."

If you have used the medicine before, compare the new pen with your previous prescription. Differences in colour, branding, labels, or the overall design should not be ignored. Even small changes may be a sign that the product is not genuine.

Most GLP-1 injections should appear clear. If the solution looks cloudy, discoloured, or contains floating particles, do not inject it. Instead, consult your pharmacist or healthcare provider immediately.

If you think your medicine may be counterfeit, stop using it immediately. Contact both your doctor and the pharmacy where you purchased it, and report the batch or lot number if possible. Seek urgent medical attention if you experience unexpected nausea, vomiting, dizziness, allergic reactions, or signs of infection after using the injection.

Dr Bansal advises that GLP-1 medicines should always be purchased from licensed pharmacies after consulting a registered healthcare professional. While these medications can be highly effective for diabetes and weight management, their benefits depend on using authentic products under proper medical supervision. Taking a few minutes to check your medicine before injecting it could protect your health and prevent serious complications.
