Here is a link to a website where there is information on many of the medications which may be prescribed to our pets to treat various conditions.

If you click on the name of any of the highlighted medications listed on the page, you will be brought to another webpage about that drug in particular.

Thanks to Diane for suggesting this link be posted here.

And here's another site with similar information:

If you click on any of the drugs listed, you'll be taken to a page about that drug where you can see a brief description of that medication and its use in Veterinary Medicine.

You can then click on "patient information sheet" to read a more detailed description of the drug (uses, contraindications, drug interactions etc)

Thanks to Sue for the second link.
