What is this Health Advice & Guides section?

This Advice & Guides section is home to a range of guides that gives you advice on a wide range of topics. The topics we cover are based on common questions that we receive as a pharmacy, including questions based on what to take for hay fever or what you can take if you are pregnant, for example.

New guides will be available regularly so keep coming back to find more advice and guidance on medical queries and issues.
