New biosimilars information sheet available

A new information sheet on Biosimilars is now available online, and to request as a hard copy.

This resource, produced as part of our commitment to providing accurate, good quality information, outlines what biosimilars are and what you need to know if you are offered one.

What are biologics and biosimilars?

There are many well-established and targeted treatments that can make a real difference and help manage psoriasis effectively over time. In the last three decades, biologic medicines have been launched and developed, which target the underlying causes of inflammation in psoriasis and psoriatic arthritis, and this has improved the management of psoriasis considerably.

When the patent (copyright) of a biologic medicine expires, the original pharmaceutical company no longer has the sole right to make the medicine. This means that other companies can then produce their own version, which are known as biosimilars. Biosimilar medicines are treatments designed to closely match an existing biological medicine.

Also covered in the new resource:

  • The difference between biosimilars and generic medicines
  • Whether biosimilars are safe and effective
  • Biosimilars and ‘interchangeability’
  • How and when you might be offered a biosimilar, and what you need to know beforehand

To find out more about Biosimilars, including information on potential side effects and other things to be aware of, you can download the full information sheet or email mail@psoriasis-association.org.uk to request a hard copy.
