If you choose to search for the brand “Dysport”, for example, you have to click on the bar next to where it says “Find Health Products”, and then a small drop-down menu with options where you want to select what you want.
Finally, go down to the bottom of the page and select the button called “Search”.
Then a page will appear where you can choose which view you want: “Standard View” or “Custom View”. If you select “Standard view”, the search results are displayed immediately.
