UK drug regulators have closed down an illegal factory making fake versions of a type of diabetes medication. These medicines are designed to mimic the effects of natural hormones in your body that help control blood sugar levels. The factory was producing these counterfeit drugs without proper approval or safety checks. This action by regulators is to protect public health and ensure that people get safe and effective medications. If you’re using these types of drugs, it’s important to get them from trusted sources and follow your doctor’s advice.
