We are all familiar with ‘best-before’ and ‘use-by’ dates on food. Medicines are very similarly labelled.
If you look at the packet of your most recent medication, you will see stamped on it somewhere, an expiry date. But what does this expiry date really mean?
Although generally not recommended, we may sometimes choose to eat certain foods beyond their ‘best before’ date. But can we do the same with medicines?
Is it really necessary to throw away, and waste, unused medicines?
Not yet. Champix is the only brand name of the drug varenicline currently available in the UK or the EU. Champix was patented in 2006, and remains under patent until September 2021 in the UK/EU – in the USA it is patented until 2020 under the brand name of Chantix, so a generic cannot be legally sold until the patent expires.
The active medical ingredient in Champix is called varenicline. Varenicline is the generic name of the product.
