Counterfeit medicines pose a serious threat to public health and safety and may cause harm to patients or fail to treat the disease they were intended for. They have been found to commonly contain corn starch, potato starch or chalk or other toxic ingredients or toxic levels of the wrong active ingredient. Additionally they may contain impurities and / or bacteria.
Unregulated websites are a potential source of counterfeit medicines. Consumers should therefore be cautious about ordering medicines online and be aware that some online pharmacies are unregistered.
